**** BEGIN LOGGING AT Sun Mar 29 03:01:48 2020 Mar 29 03:01:54 Should I take the lamp apart? Mar 29 03:01:55 Yes, that Flickr has lots of cool photo's. Even BBB is there now Mar 29 03:02:13 Ever heard of a program called makeLED ? Mar 29 03:02:18 Nope. Mar 29 03:03:01 It's cool. It lets you play with the user0 led. I hav the source written in C Mar 29 03:03:15 KenUnix: I will be gone exactly 7.25 minutes. brb! Mar 29 03:03:32 What he source? Mar 29 03:03:41 For later? Mar 29 03:07:53 Ha. Mar 29 03:08:00 Hey. My lamp parts are missing. Mar 29 03:08:06 I need some extra time. Mar 29 03:08:13 Can you wait while I look for my lamp parts. Mar 29 03:08:14 ? Mar 29 03:09:30 KenUnix: I need to find a lamp socket real quickly. I have none on hand in front of me. Mar 29 03:09:37 Are you going to be here in a bit? Mar 29 03:09:51 15 min. max! Mar 29 03:12:10 Okay. Mar 29 03:12:17 I found a keyless Socket adapter kit. Mar 29 03:12:43 Ckeck out the "C" code here https://paste.debian.net/1137177/ Mar 29 03:12:45 /nick MattB00ne Mar 29 03:13:35 test Mar 29 03:13:51 c++ makeLED.cpp -o makeLED Mar 29 03:14:14 'C" is good Mar 29 03:14:33 Okay. Mar 29 03:14:41 I saw the source. Nice. Mar 29 03:14:49 I need to wire this stuff real quickly. Mar 29 03:15:07 Look. You'll like it. Its got if else Mar 29 03:15:26 Download and try to compile Mar 29 03:16:10 Okay. Mar 29 03:16:19 I might try it later. Mar 29 03:16:54 The typing on this socket adapter is so small, i.e. you would think Microsoft typed it. Ha. Mar 29 03:18:34 Ha! =D Mar 29 03:19:02 No, Microsoft would use reverse threads Mar 29 03:19:16 test Mar 29 03:19:40 mattbone test Mar 29 03:20:13 Matt do you have a BBB? Mar 29 03:20:19 I do Mar 29 03:20:30 well it's a green Mar 29 03:20:35 but close enough Mar 29 03:20:39 Ever play with the user leds? Mar 29 03:20:49 nope Mar 29 03:21:13 Ckeck out the "C" code here https://paste.debian.net/1137177/ Mar 29 03:21:15 actually I did for about 2 min following molloys book Mar 29 03:21:43 ha I see you are doing the same Mar 29 03:23:14 So... Mar 29 03:23:34 NO goes to the bulb and GND goes to the bulb too? Mar 29 03:24:04 Then, Power or positive goes to the COM terminal on the relayCape? Mar 29 03:25:20 Yep. Mar 29 03:25:46 Okay. I have this socket adapter to use so I do not shoot sparks all over my skin. Mar 29 03:26:04 And - to the other side of the bulb Mar 29 03:26:17 FYI, I do not like making mistakes in wiring and creating my skin to burn. Mar 29 03:26:26 Okay. Mar 29 03:26:51 So, this is a three-wire set up, right? Mar 29 03:26:51 Burn? it's only 12 volts. Mar 29 03:27:09 Still, DC of so many watts will get anyone the gitters. Mar 29 03:27:32 battery negative to bulb Mar 29 03:27:47 bulb other side to no relay Mar 29 03:28:04 com relay to battery positive Mar 29 03:28:29 I could just use tape, I guess. I could use electrical tape to hold on my wiring to the naked bulb. Mar 29 03:28:56 naked bulb? Mar 29 03:29:20 w/out the socket. I could just use the bulb w/out the socket. Mar 29 03:30:56 Well, ok. be careful BBBZZZZZAp Mar 29 03:31:25 I do not know how this adapter works. Dang it. Mar 29 03:31:27 Please hold. Mar 29 03:32:41 Dang holes in the sides. I need another wiring harness. Please hold. Dang... Mar 29 03:42:57 Ghetto Rig...here I come! Mar 29 03:43:12 I am going to use some electrical tape on the bare bulb. Mar 29 03:51:07 Okay... Mar 29 03:51:27 I got everything connected. Power comes in a bit. Then, the source will be done, too. Mar 29 03:52:34 Hold. I need to get a fire extinguisher. Captain Safety says, "One more skin burn is not what I am about!" Mar 29 03:54:32 Can I use 5v AC for this Cape? Mar 29 03:54:50 I might need to instead of the 12v battery. Mar 29 03:56:45 Sure but only on the contacts Mar 29 03:57:10 KenUnix: What contacts? Are you talking about the bare bulb? Mar 29 03:57:36 No A.C across C and NO Mar 29 03:58:08 Right, one contact goes to NO and the other contact goes to GND on the battery. Mar 29 03:58:09 Okay. Mar 29 03:58:34 We are discussing the bulb right? Mar 29 03:58:41 I have to go. My right is acting up again. Everything is blury Mar 29 03:58:59 I have to go. My right eye is acting up again. Everything is blury Mar 29 03:59:08 Okay. Mar 29 03:59:11 Enjoy! Mar 29 03:59:25 Say no to the COVID-19. Mar 29 03:59:30 Oh well. Mar 29 04:04:14 Okay. I am fully powered and ready to rumble. I cannot wait until I can show the video to KenUnix. Mar 29 04:06:49 Alright, I heard it click. Mar 29 04:06:57 No light action, yet. Mar 29 04:07:31 It is probably the config-pin utility. I will test it real quickly. Mar 29 04:08:47 Nope. Not that. Mar 29 04:09:00 It must be my wiring. Mar 29 04:10:37 It is three wires. Mar 29 04:10:41 How could it be? Mar 29 04:11:26 I should poke it w/ a plastic pen. Mar 29 04:12:22 Or...is it this dang, ole battery? Mar 29 04:12:24 Sheesh. Mar 29 04:15:11 Nope, not the battery. Mar 29 04:16:02 Well, the Cape works supposedly. Oh! Mar 29 04:16:25 The Cape LED comes on and the switch clicks. I did not plug it in via barrel jack! Mar 29 04:16:33 Aw! Mar 29 04:17:15 So far only 1600 people have died in the US and their are only 100000 cases. These are in WA NJ and NY mostly. Mar 29 04:17:38 Oh. Mar 29 04:18:11 I am neck deep in switches and you are discussing deaths. How selfish. Mar 29 04:18:12 Ha. Mar 29 04:18:14 Just kidding. Mar 29 04:18:16 Sorry. Mar 29 04:20:22 Ok well I am heading to sleep take care. Mar 29 04:20:27 No! Mar 29 04:20:40 GenTooMan: Please wait. Mar 29 04:33:15 I got the LED to turn on during functioning of the RelayCape but the light bulb does not turn on. Mar 29 04:33:27 Is anyone else working w/ the RelayCape? Mar 29 04:35:46 COM is ground! Mar 29 04:35:54 I wonder why KenUnix told me differently. Mar 29 04:36:00 Odd days. Mar 29 04:36:16 Anyway. Living, breathing, chatting. Okey! Mar 29 04:52:50 Oh well. I tried the Relay1 Relay. I will try another one. Mar 29 04:56:52 I have gpio20 listed in /sys/class/gpio/ but I cannot use config-pin to make the pin work. The Cape works. I can hear the clicking from the switch and the LED onboard the RelayCape shows on and off. Mar 29 05:01:22 What do you think I am doing incorrectly? Mar 29 05:15:58 Oh well. Mar 29 05:16:06 Another day, another time. Mar 29 05:26:39 I guess it is b/c it is a 40w bulb and I am using 12v at 1.3Ah to crank it on via switch. Mar 29 05:27:00 I will look for another light to use. Mar 29 05:56:06 hi Mar 29 05:56:48 is it possible to develope pico projector pcba with beagle board Mar 29 06:54:17 dhan: that's more a question about your abilities than about the board Mar 29 09:41:30 hello Mar 29 09:42:15 i just requested for elinux wiki account. I got a verification mail. But it never asked me to set a password. Can anyone tell me how can i login now Mar 29 10:01:35 the register page says "your password will be emailed to you when your account is created" Mar 29 10:02:00 (i.e. after you click the confirmation link in the verification email) Mar 29 10:11:09 ok how long will it take, i did it half an hour ago still no password. The deadline for proposal is near Mar 29 10:12:44 I want to submit a proposal on Reference Design For A GPIO-based Parallel Bi-Directional Bus Mar 29 10:13:05 Is there any mentor with whome i can share my drafts Mar 29 10:13:59 my previous work https://deebot.github.io/ Mar 29 10:14:41 I have done some work with MUX to extend the pins of arduino using a TLC5940 chip Mar 29 11:00:00 deepankarmaithan: there's a separate channel #beagle-gsoc for gsoc questions... as for the elinux wiki, I'm not sure where the right place is. do be sure to check if it's accidently got marked as spam and ended up in your spam box Mar 29 11:51:24 ok thanks Mar 29 15:03:07 Is anyone using the RelayCape for lighting purposes? Mar 29 15:04:36 I am reading about relays but I see the COM terminal on the Cape is for GND. Is this a fact? I checked the schematic. Mar 29 15:08:34 The schematic definitely states that COM is GND. I am assuming that the pin mux has been done in EEPROM on the pins for this Cape. Mar 29 15:08:46 I will test it soon. Mar 29 15:18:17 https://drive.google.com/file/d/190170R10zAqb5Lpm_QirXWp5jYhyFlW1/view?usp=sharing is my funny schematic of the setup. Mar 29 15:18:33 Is that schematic correct? Mar 29 15:18:33 How about i warn you about lighting loads and relays instead? First are you using an incandescent lamp? If so the relay turn on current is VERY high for those. Normal relays contacts will be toast. Mar 29 15:18:48 Oh. Mar 29 15:18:58 I am using a normal light bulb and not a LED. Mar 29 15:19:24 They rate relays differently for lighting loads. I suggest an LED lamp might be better. Mar 29 15:19:36 Okay. Mar 29 15:19:46 Also check what the data sheet for the board says. Mar 29 15:19:56 I will go and get a LED bulb. Mar 29 15:20:23 The board/Cape does not say much so far. I think people are still using it as a prototype. Mar 29 15:20:32 It is not in production. Mar 29 15:21:05 15A at 24v. Mar 29 15:21:42 So, I am using 12v at what i would guess is ____A? Mar 29 15:23:55 My light bulb is busted. Mar 29 15:24:27 This is why it was not lighting or not exploding. Either way, I will get a LED bulb for this task now. Mar 29 15:26:32 are you using the cape from GHI Electronics? Mar 29 15:26:37 Yes sir. Mar 29 15:26:46 RelayCape from GHI. Mar 29 15:27:14 The Cape works. I tested it w/ a 12v 1.3Ah battery. Mar 29 15:27:44 I heard the clicking of the relay and the LED came on and went off. Mar 29 15:28:27 Ok you are running a 12V lamp? or 120V lamp? Mar 29 15:29:00 I am directly connecting the bare bulb to wiring to test it. Mar 29 15:29:20 Do the relays say "AC" or "DC" load? Most relays are 30V DC and 120V AC max. Mar 29 15:29:28 Let me see. Mar 29 15:29:32 Please hold. Mar 29 15:29:53 I think w/ these relays, one can use either DC or AC. Mar 29 15:30:30 From what is stated here: https://beagleboard.org/capes Mar 29 15:30:31 * GenTooMan points to what he said 30VDC and 120VAC Mar 29 15:30:47 Scroll down to RelayCape. Mar 29 15:31:01 it has a very brief intro. into these relays. Mar 29 15:31:16 I will check the relay again. Mar 29 15:32:18 Umm yeah. What is the voltage rating of the device you are trying to turn on? Mar 29 15:32:52 120VAC Mar 29 15:33:11 at 10W Mar 29 15:33:48 Try a 12V lamp Mar 29 15:33:51 The relay lettering is too small to read. Mar 29 15:33:53 Okay. Mar 29 15:34:22 12v lamp? Where would I find that? Mar 29 15:34:45 Everything I own is AC at 120v for lamping. Mar 29 15:34:53 The lamp won't turn on if the voltage is too small so your other lamp may not be busted. You can get 12V bulbs from any automotive place. Mar 29 15:35:07 Got it. Mar 29 15:35:09 even LED ones Mar 29 15:35:09 You are right. Mar 29 15:35:11 Nice. Mar 29 15:35:24 I will test it soon... Mar 29 15:35:28 First, to the Store! Mar 29 15:35:36 occasionally I am (right that is) Mar 29 15:35:46 You are right a lot, I have noticed. Mar 29 15:36:07 Anyway, you are more correct in this field compared to me. "Like you did not know." Mar 29 15:36:32 Well I am glad you are not using 120V or things could be a bit shocking, Mar 29 15:36:41 bzzt, bzzt! Mar 29 15:37:00 Caution! High Voltage! Mar 29 15:37:32 24VDC and 240VAC! Mar 29 15:37:34 Yikes! Mar 29 15:37:58 That is the highest load these relays can handle. Supposedly. But, shall I test it? No. Mar 29 15:38:10 24VDC can burn you if you are't careful but 240 you can definately feel 480 is quit painful Mar 29 15:38:19 Ha. Mar 29 15:38:58 I actually was working on cleaning something near electricity once. Something jumped into a socket, 240VAC, and it arched. Mar 29 15:39:14 Talk about, some scary situations. Mar 29 15:39:33 Oh notice I said 30VDC that's DC equivalent in hazard as 120V ... keep that in mind Mar 29 15:39:43 It was basically lightning shooting out of the wall. Mar 29 15:39:44 Okay. Mar 29 15:39:56 Okay. Mar 29 15:40:38 Too bad I did not have some wood around to catch the lighting wall. I could have made some neat wood markings. Mar 29 15:41:03 Anyway. I will be heading to the store later to get this 12v LED lighting for testing this Cape. Mar 29 15:41:06 Thank you, sir. Mar 29 15:41:40 https://www.tindie.com/products/icstation/mini-tesla-coil-plasma-arc-speaker-diy-kit-13034/ Mar 29 15:42:04 GenTooMan: Is there a formula for exchanging ac to dc and back? Mar 29 15:44:27 ac / sqrt2 Mar 29 15:44:38 ? Mar 29 15:44:41 I said hazard Mar 29 15:45:00 I got you. I am not going to do anything silly (hopefully). Mar 29 15:45:34 I will not attempt to mess w/ things over 12v unless I use my powerswitch tail II. Mar 29 15:45:37 AC has a chance of you letting GO not so with DC it will cook your behind permanently and you CAN'T let go. Mar 29 15:45:50 Yikes. Mar 29 15:46:41 I know it is serious, sir. I am not baffled by its power. Mar 29 15:46:58 No pun intended. Mar 29 15:47:24 24VDC is skirting the difficult zone with DC, you have to be MUCH more careful around high voltage DC. Mar 29 15:48:18 Okay. This is good to know. Are there any precautions you would take that I may have overlooked? Mar 29 15:49:23 I have quick disconnects on the end of my wiring w/ them crimped well from a crimping tool. Mar 29 15:50:35 I wear glasses during my tests, I have a fire extinguisher, and I connect GND first to the DC supply before positive connections. Mar 29 15:51:08 But... Mar 29 15:51:32 No loose wires only connect what you are testing. Remove any connection you aren't using don't lean near wires. Think that way. Mar 29 15:51:45 One thing I did overlook is the sheer Voltage of the lights I was using w/ my 12v battery. Mar 29 15:51:46 Okay. Mar 29 15:51:50 Good move. Mar 29 15:52:09 I need to remove my other boards and other wiring setups near my current project. Mar 29 15:52:20 Clean and clear! Mar 29 15:52:26 Think of each wire as a potential eye gouger. If you don't want to be poked in the eye don't get near it. Mar 29 15:52:43 I hate eye poking. Literally. Mar 29 15:53:23 Electrical eye pokes should be worse, I am assuming. Mar 29 15:54:14 Let me break for a bit. I need to think about what i have done and research it. Mar 29 15:54:34 right ... now to put in the CPU Mar 29 15:59:11 What do you mean? Mar 29 15:59:18 Are you attaching a CPU? Mar 29 16:00:13 Or... Mar 29 16:00:27 Do you mean the am335x w/ the RelayCape? Mar 29 16:01:52 you know I have about 20 different processor boards excluding 3 PCs? I am upgrading my big PC that's all had to find the thermal paste to put the heat sink on Mar 29 16:02:03 Oh. Mar 29 16:02:33 Yea. I got some stuff too. It looks like a turkey injector. Cooling for the even flow of heat! Mar 29 16:02:38 I have some REALLY old stuff including 2 of the first beagle boards. Mar 29 16:02:43 Oh. Mar 29 16:03:17 Do your beagleboards work still? Mar 29 16:05:16 I have no idea. Probably I used to use the PICO projector with one. The issue with that was TI screwed up the settings for the LEDs and the projector would over heat. Mar 29 16:05:28 GenTooMan: You do not have to answer. Do not worry about it. I am off to "da" "sto." Mar 29 16:05:29 No! Mar 29 16:05:53 have fun only buy what you need. I suggest looking online first then hunt the parts down. Mar 29 16:05:54 Heat is the enemy of plastic. Mar 29 16:06:04 Okay. Smart idea. Mar 29 16:06:17 Advanced Auto Parts! Mar 29 16:08:12 Should I get a halogen or a LED type of 12v light? Mar 29 16:13:34 Anyway, the LED bulbs are very expensive. I will get one for testing but if this thing blinds me from light density, I am calling my mommy! Mar 29 16:14:20 $9.00 for one! Mar 29 16:51:54 * GenTooMan returns blinking Mar 29 16:53:20 I know! Mar 29 16:53:37 I went to Wally World and found a LED for automotive use. Mar 29 16:53:44 So... Mar 29 16:53:54 I need to find the datasheet on it. Mar 29 16:53:56 brb Mar 29 16:57:32 Well, sylvania does not have a datasheet for whatever LEDs they are using. Mar 29 16:59:49 "It is a secret!" Mar 29 17:01:28 part number Mar 29 17:01:51 sylvania is the parent company not the actual manufacturer. Mar 29 17:04:16 Oh. Mar 29 17:04:28 Let me see. Mar 29 17:04:30 Please hold. Mar 29 17:04:42 3157 Mar 29 17:05:06 Off road! Mar 29 17:05:13 In house, off road! Mar 29 17:06:27 This plastic encasing is going to give me trouble. I know it. Mar 29 17:07:26 this? https://www.sylvania-automotive.com/products/interior-and-exterior-bulbs/long-life/3157_longlife.jsp Mar 29 17:07:43 3157 may be the part it's replacing Mar 29 17:07:58 Oh. Let me show you. That is not it. Mar 29 17:09:04 scroll down dude Mar 29 17:09:22 there are 3 products that have the 3157 added to it Mar 29 17:09:41 6000K Mar 29 17:09:48 Those are not them. Mar 29 17:10:38 there are 3 products on that page Mar 29 17:10:42 :D Mar 29 17:10:44 I saw them. Mar 29 17:10:49 None of those. Mar 29 17:10:52 I have the link. Mar 29 17:10:55 right Mar 29 17:10:57 But the link is long. Please hold. Mar 29 17:11:36 https://pastebin.com/WjuMca32 Mar 29 17:14:27 these https://www.sylvania-automotive.com/products/interior-and-exterior-bulbs/sylvania-led/3157_syl_led.jsp Mar 29 17:16:07 Nope. Mar 29 17:16:11 I checked all on that page. Mar 29 17:16:16 Did you look at my link? Mar 29 17:16:38 On the paste, it is just a link. Mar 29 17:17:08 Try 6000K too. Mar 29 17:17:16 I will look on their site. Mar 29 17:18:18 https://www.amazon.com/SYLVANIA-3157-White-Contains-Bulbs/dp/B01BDWI1BS Mar 29 17:18:31 It is the 6000K version and not the White Light version. Mar 29 17:19:00 12v, 2W! Mar 29 17:20:37 Just for reference, everyone here sells us old stuff. It may be out of production. Mar 29 17:22:05 I think these older models were stopped and ZEVO from sylvania was the new item w/ the 6000K versions. Mar 29 17:22:10 you have the LED's already I assume? at 2W they only require 170ma so you could hook to the pins with clip leads. Mar 29 17:22:23 Okay. Yes sir. I have them. Mar 29 17:23:27 you can diode check them with your multi meter to determine polarity. Mar 29 17:23:41 Issue Number One: I have no clip leads (I am pretty sure). Okay. I will check the polarity. Mar 29 17:33:34 Okay. I checked. Mar 29 17:33:43 mark the negative side with a black permanent marker IE what clips to the black lead of the multi meter Mar 29 17:33:47 Right! Mar 29 17:33:48 On it. Mar 29 17:34:11 Now, off to find another marker. Stuff runs out, man. Mar 29 17:34:35 you don't have allagator clips or fast clips? hmm problematic Mar 29 17:35:20 I might but they are not connected to wirings. Mar 29 17:35:33 I have two pair, actually. Mar 29 17:35:54 One set has no wiring and the other are bullet plugs on the other end. Mar 29 17:36:02 Ha. Mar 29 17:36:23 I have electrical tape. I will test w/ that. Mar 29 17:37:38 Okay. Marked up w/ black ink. Mar 29 17:38:10 GenTooMan: This is exciting for me. Mar 29 17:39:33 I can try to jam some wiring in the aligator clips and mash the ends together w/ a crimper. Mar 29 17:46:34 Okay. the aligator clip is crimped. Mar 29 17:46:45 "ret" to go. Mar 29 17:47:26 GenTooMan: What next? Mar 29 17:49:21 If the negative side of the diode test is known, what should I do w/ the postive side of the LED? Mar 29 17:52:26 hopefully you connected the negative side to the negative terminal of the battery and the COMMON should be connected to the positive side, verify that is what you have hooked up Mar 29 17:52:33 hopefully you connected the negative side to the negative terminal of the battery and the COMMON should be connected to the positive side, verify that is what you have hooked up Mar 29 17:52:44 argh ... Mar 29 17:54:00 Okay. Mar 29 17:54:46 So, COM (common) on the Cape goes to the positive terminal on the battery. Mar 29 17:54:47 Okay. Mar 29 17:54:55 And... Mar 29 17:56:17 The negative terminal on the battery goes to the aligator clip to the LED negative terminal on the LED. Mar 29 17:56:26 Is that right? Mar 29 17:58:24 GenTooMan: Do I need three wires or only two? Mar 29 17:59:14 Positive Wire: COMMON to 12v supply Positive! Mar 29 17:59:28 Negative Wire: NO to LED negative! Mar 29 17:59:42 But...what about the negative terminal on the battery? Mar 29 18:02:13 Ummm LOOK AT YOUR DIAGRAM Mar 29 18:02:37 Do you mean, that funny one I put together? Mar 29 18:02:56 Yes.. NO is positive according to the diagram Mar 29 18:03:18 which means COM is positive Mar 29 18:03:30 So, my diagram is incorrect? Mar 29 18:03:50 Either COM is positive or NO is positive. Mar 29 18:04:04 they both are. Mar 29 18:04:26 when the relay turns on COM shorts to NO Mar 29 18:04:37 Oh. Mar 29 18:04:43 Okay. Mar 29 18:05:28 So, three wires. Mar 29 18:07:15 So, I can use NO for the positive terminal on my battery or should I use COM on the Cape for the postive terminal on the battery? Mar 29 18:08:14 Go with your diagram ... it's written down Don't Change something midway unless you document it (IE redraw the diagram( Mar 29 18:08:29 GenTooMan: Does COM definitely need to be directly linked to the positive terminal on the battery? Mar 29 18:14:06 set_ it doesn't matter which it's connected to technically but you have a diagram stick with it. Mar 29 18:15:54 Okay. Mar 29 18:16:24 I was asking b/c on the schematic for the RelayCape, it shows that COM is GND on the board. Mar 29 18:16:46 So, I would use NO or NC for powering the device. Mar 29 18:16:58 When it switches, like you said. Mar 29 18:18:06 https://github.com/beagleboard/capes/blob/master/beaglebone/Relay/Relay_Cape_sch.pdf shows on page two of two that COM is GND. Mar 29 18:18:36 I think this is why I was wondering why COM is listed as positive in other ideas. Mar 29 18:19:43 Generally you switch positve or non ground lines Mar 29 18:20:22 Oh. Okay. That makes sense to me but the .pdf shows COM as negative/GND. Mar 29 18:20:32 What do you think was the idea behind this notion? Mar 29 18:20:47 you only need to connect the supply to COM if you what to use both the NC and NO line if you don't want power on NC ever don't hook the battery to common Mar 29 18:21:01 Okay. Got it. Mar 29 18:21:04 Thank you, sir. Mar 29 18:21:17 My source does the work for on/off operations. Mar 29 18:21:31 I just use a simple bonescript example to test so far. Mar 29 18:21:59 So, if this, do that. Else, do this. Mar 29 18:22:29 Actually, I think I have it on a timer too. Mar 29 18:24:17 umm you are just testing if a load switches right? So you have the LED positive connected to COM and LED negative hooked to battery minus. Time to test? Mar 29 18:24:46 don't blind yourself? Wear sun glasses in other words Mar 29 18:25:05 or put them on before you run the script at least Mar 29 18:25:12 Right. The load needs to be switched. Mar 29 18:25:23 ... Mar 29 18:25:55 you got high brightness LEDs hence "dude don't cook your eyes" Mar 29 18:26:03 Okay. Mar 29 18:26:18 other option is a piece of paper over the LED Mar 29 18:27:02 I obviously am thinking that there needs to be four wires now. Mar 29 18:27:58 If battery positive is to be attached to COM and the LED, then I will need four wires b/c the battery negative needs to be attached to the NO and LED too. Mar 29 18:34:33 set_ what the heck are you talking about? if battery positive is attached to NO already you just shorted your battery Mar 29 18:36:42 you need to complete a circuit. current flows positive to negative in EGR convention so positve terminal goes to NO, COMMON is connected to LED pos and LED neg is connected to the negative terminal of the battery. That would be a complete circuit when the relay is turned on Mar 29 18:40:08 follow the diagram ... so you don't kill your battery :D Mar 29 18:41:55 GenTooMan: I am talking about this. Do I need four connections on my LED? Mar 29 18:42:46 Or just three connections? Mar 29 18:44:23 you are confusing yourself (truth) what does your diagram have on it? Go by what you drew on the diagram. Mar 29 18:45:37 your LED is a 2 terminal device by the way. In fact you have 3, 2 terminal devices, a battery a relay (switch) and an LED they are all connected in series. Mar 29 18:47:55 Right. Okay. I am confused right now b/c of something. Mar 29 18:48:17 This something is two terminals on the LED needing three wires, right? Mar 29 18:48:28 I will just test it. Mar 29 18:48:30 Forget it. Mar 29 18:49:13 as i said follow the diagram don't over think yourself into blowing something up. Mar 29 18:51:50 I have my googles on and I am testing! Mar 29 18:52:02 Please wait for eithe disaster or greatness. Mar 29 18:53:23 I have a prior engagement so I may not be able to respond Mar 29 18:53:46 Have fun! Mar 29 19:00:29 Nither/nor...the light did not light up. I will go to google groups and see if anyone else is using this cape. Mar 29 20:07:03 short NO to common see if the LED device lights up. Mar 29 20:20:59 GenTooMan: When you say "short," what are you expecting me to do? Mar 29 20:27:14 connect a wire from NO to COM and see if the LED lights up? Mar 29 20:28:29 The LED oboard the Cape? Mar 29 20:29:18 Or make a circuit from NO to COM on the Cape w/ the "offroad" LED? Mar 29 20:29:59 oboard = onboard Mar 29 20:33:56 So, Positive LED to NO. Then, Negative LED to COM. Then, power the Cape and run the source? Mar 29 20:34:03 or... Mar 29 20:34:12 Should the LED just brighten up? Mar 29 20:37:43 Okay. I just put NC to Positive LED && COM to Negative LED. Notta and I am plugged in via the 5v barrel jack and w/ usb networking. Mar 29 20:39:01 I will try COM to Positive LED and NO to Negative LED next. Mar 29 20:41:46 Maybe I am attaching it to the LED incorrectly? Mar 29 20:44:33 OK set_ how about positive EX LED to positive bat and negative EX LED to negative bat? Mar 29 20:44:52
