**** BEGIN LOGGING AT Mon May 08 03:00:02 2017 May 08 15:02:43 do I have all the addresses and hardware requirements? May 08 15:24:27 welcome back beagleslackbot May 08 15:39:44 jkridner: I've emailed you my address. On hardware requiremnts , I think a beaglebone blue or black and x15 May 08 16:24:04 jkridner: just sent you mine :) May 08 16:54:24 k. so far, I only have 2 people on the spreadsheet that have hardware requirements listed. Mentors should be filling those sections in. I don't have many chances to do this, so today was the day I was going to do all the orders. May 08 16:54:58 please don't send me personal e-mails (except you ravikp7, since I'm your mentor). May 08 16:55:09 btw, ravikp7, I placed the order for your hardware just a few minutes ago. May 08 16:55:45 * jkridner is trying to avoid doing shipments personally this year, since we have worldwide distributors to leverage... worth paying the few dollars extra. May 08 16:59:00 jkridner: since I am assembling the units for my student's project how would the billing and shipping work? May 08 17:00:21 so, hardware should arrive soon.. May 08 17:01:52 perhaps I can create a cart at digikey then forward it or I could invoice after everything is ordered (up to $300) May 08 17:08:54 jkrider: Sorry! May 08 17:59:54 m_w: we have an org credit card. May 08 18:00:08 m_w: is there a way I can charge it for the stuff? May 08 19:02:55 can mentors put in requests for hardware or are mentors expected to buy their own? i'm find with buying my own, but the x15, for example, is almost impossible to get through regular channels May 08 19:03:02 s/find/fine May 08 19:03:27 jkridner: well I need to order the PCBs from OSHpark and the parts for various vendors May 08 19:04:49 I pay OSHPark via PayPal. If you put things up as shared projects, I can place orders. Trying to pay you back for stuff is more complex for me. May 08 19:05:30 jkridner: I will push the project up to oshpark May 08 19:08:36 I have a gift code from Drew that I can forward to you May 08 19:11:55 https://oshpark.com/shared_projects/WSmG2ZOf May 08 19:12:44 jkridner: ^ here is the board May 08 19:13:36 k, make sure to add it to the spreadsheet with addresses. I'll plan to drop-ship from OSHPark. May 08 19:17:49 jkridner: I sent you an email with the discount code the pdp7 sent me May 08 19:18:09 it should get us three copies for ~$44 May 08 19:18:34 my address is already up to date in the spreadsheet. May 08 19:19:26 the boards and components will go to me first for assembly then I will ship one unit to pmezydlo and one to jic23 if required May 08 19:22:04 pmezydlo: has your address changed since last year? May 08 19:22:26 my address is the same May 08 19:24:43 so both of our addresses are up to date on the document May 08 19:26:18 jkridner: looks like the PCBs will be free, neglecting shipping once pdp7 give you the new code May 08 19:26:50 pmezydlo: do you have a spreadsheet for the BOM or a Digikey cart for the components? May 08 19:28:04 m_w: no but if you need it I can prepare May 08 19:28:25 pmezydlo: please provide one or both of those ASAP May 08 19:28:50 if you can't do it soon, I will take care of it May 08 19:29:42 m_w: no problem I will do it now May 08 19:30:11 pmezydlo: aweseome, let me know if you can't find any of the parts on Digikey May 08 19:38:05 I think the grove connectors might be difficult to source May 08 19:47:47 m_w: I see only tht grove connectors May 08 19:56:16 m_w: I have a problem with flash memory (http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail&itemSeq=227411932&uq=636298520688454620) on digikay You have to order 1800 pieces May 08 20:40:56 pmezydlo: lets see May 08 20:44:16 pmezydlo: MT25QL128ABA1ESE-0SIT is the compatible cross according to the EOL document May 08 20:45:46 there are probably other compatible crosses as well May 08 20:46:57 most SPI flashes have a standard interface so that many parts can be used interchanibly May 08 20:47:07 interchangibly May 08 20:48:27 ok I added to list, Could you find sdram memory I have problem with it May 08 20:48:39 MT48LC32M8A2P May 08 20:50:14 m_w: ^^ May 08 20:50:28 pmezydlo: those look difficult to source as well May 08 20:50:45 lets see if we can find a compatible cross for that too May 08 20:52:10 https://www.digikey.com/product-detail/en/alliance-memory-inc/AS4C16M16SA-6TIN/1450-1253-ND/5214129 May 08 20:53:21 that should work May 08 20:54:43 should double check the pinout though May 08 20:55:17 I have found almost all the elements May 08 20:55:53 http://www.issi.com/WW/pdf/IS25LP032-064-128.pdf May 08 20:56:17 this is possibly a cross for the SPI flash May 08 20:57:30 memories are notorious for sourcing issues May 08 20:59:34 yeah pinout is good, timings probably too May 08 21:04:26 https://www.digikey.com/product-detail/en/jst-sales-america-inc/S4B-PH-SM4-TB(LF)(SN)/455-1751-6-ND/1963618 May 08 21:04:41 check if this will work for the grove connector May 08 21:12:46 don't think that are quite the same May 08 21:15:35 sorry for delay, I was adding resistors at the moment May 08 21:18:53 m_w: this is link to shoping card: http://www.digikey.com/short/3n512z May 08 21:19:10 *cart May 08 21:22:42 we also need buttons, eeprom, grove May 08 21:29:22 okay May 08 21:29:58 I have written an email to my contacts at Seeed studio about the grove connectors May 08 21:30:09 hopefully they are willing to help out May 08 21:30:24 I will take it from here I guess May 08 21:31:16 We use CAT24C256 instead AT24CS32-XHM May 08 21:35:59 pmezydlo: thanks May 08 21:36:28 If you can pls add buttons I can't find it May 08 21:37:21 yes I can May 08 21:38:56 https://www.digikey.com/product-detail/en/te-connectivity-alcoswitch-switches/147873-2/450-2049-1-ND/4146922 May 08 21:40:42 going to switch the issi spi flash so that we can get them immediately instead of back order May 08 21:42:20 This is my actual list: http://www.digikey.com/short/3nrchh May 08 21:44:23 118$ for parts on 3 boards May 08 21:44:51 Good result in my opinion May 08 21:46:20 24 items in the cart minus the grove connector May 08 21:46:39 I will forward this to jkridner and have them ordered May 08 21:52:07 ok fine, May 08 21:53:02 grove connectors aren't necessary May 08 21:53:36 yeah we can add them in the future if Seeed makes them publically available May 08 21:54:29 but In my gsoc video I want to show a board and I will describe all parts May 08 21:55:00 okay, lets see how turns out? May 08 21:55:15 I think it will be okay May 08 21:56:42 I have to go, bye see you on wednesday May 08 21:56:55 good night May 08 22:07:41 m_w: hey do you have a minute? May 08 22:07:50 ordsen: sure May 08 22:08:22 sorry your project didn't make it in this year, I really liked it May 08 22:08:46 yeah, as I was rejected from gsoc it would be nice to know what I should have done different May 08 22:09:22 you did good it was just lack of mentoring resources May 08 22:10:07 your involvement and effort was great but we only had so many mentors and slots May 08 22:10:31 ok thanks, yeah I understand that! May 08 22:10:56 I still feel bad about it because I think your project would have been great May 08 22:11:43 you can still work on it on your own time May 08 22:12:07 Thanks. At least I learned some new skills during my preparation :) May 08 22:12:39 I thought about that too May 08 22:12:43 maybe you can come back for another try next year May 08 22:13:00 do you have another year of school after this one? May 08 22:14:23 At the moment I'm looking for a job at my university (student assistant and the like), don't know yet how much time will remain May 08 22:14:40 m_w: yes, one year from now May 08 22:18:10 I'm currently attending lectures for realtime systems, maybe there will be a nice project with that topic next year. I will check that out when it's time May 08 22:19:08 sounds good **** ENDING LOGGING AT Tue May 09 03:00:01 2017
