Sep 07 13:23:33 <av500> nerdboy: ack
Sep 07 13:23:44 <av500> nerdboy: next year we have hardware shipped before students apply!
Sep 07 13:23:54 <av500> nerdboy: so polish that xtal ball
Sep 07 17:15:53 <nerdboy> av500: understanding the requirements, mapping to appropriate hardware/etc would be good
Sep 07 17:16:27 <nerdboy> minimize extraneous blah blah
Sep 07 17:57:38 <mr_science> i thought the murata sensors should work okay, turned out more painful...
Sep 07 22:31:09 <thetransformerr[> Powerful In the sense???
Sep 07 23:06:49 <m_w> tlwoerner: sorry about the shipping cost on the lofive
Sep 07 23:07:06 <m_w> it is just crazy for international shipping
Sep 07 23:07:32 <tlwoerner> m_w: no probs, normal part of the process
Sep 07 23:07:41 <m_w> I have heard multiple complaints so far
Sep 07 23:07:51 <tlwoerner> i'm just playing around with the riscv-tools now :-)
Sep 07 23:08:00 <tlwoerner> nah, no complaints from me :-)
Sep 07 23:08:11 <m_w> cool
Sep 07 23:08:31 <m_w> did you order the ftdi breakout for the jtag programming of the unit?
Sep 07 23:09:32 <tlwoerner> yes, i ordered one of those too
Sep 07 23:09:52 <m_w> okay good that is the easiest route to getting started
Sep 07 23:10:07 <tlwoerner> i probably already have some form of an ftdi breakout already somewhere, but i figured this would be easier
Sep 07 23:10:19 <m_w> cool
Sep 07 23:10:19 <ds2> m_w: how power hungry is the riscv?
Sep 07 23:10:32 <m_w> not too bad
Sep 07 23:10:55 <tlwoerner> CortexM0+ range, i think?
Sep 07 23:11:13 <ds2> worse or better then a BBB?
Sep 07 23:11:36 <m_w> much better than BBB for this board
Sep 07 23:12:15 <m_w> 12mA at 5V
Sep 07 23:12:26 <ds2> hmmm not quite battery friendly
Sep 07 23:12:27 <m_w> that is idle though
Sep 07 23:12:33 <m_w> not really
Sep 07 23:12:52 <ds2> is this a real chip or a FPGA?
Sep 07 23:12:53 <m_w> lipo maybe but not coin cell
Sep 07 23:13:07 <m_w> this one is an actual chip
Sep 07 23:13:11 <m_w> https://hackaday.io/project/26909-lofive
Sep 07 23:13:23 <tlwoerner> https://riscv.org/faq/ question10
Sep 07 23:13:33 <m_w> https://www.sifive.com/products/freedom-e310/
Sep 07 23:13:59 <m_w> it is always about the implementation
Sep 07 23:14:46 <m_w> this particular chip was probably not focused on low power
Sep 07 23:15:10 <ds2> *nod* just like the MIPS
Sep 07 23:15:50 <m_w> in the same lines
Sep 07 23:16:12 <m_w> the architecture is pretty text book ;)
Sep 07 23:16:57 <m_w> but the ISA in free and anyone can make a chip based on it
Sep 07 23:17:44 <ds2> wonder if it will fit in an ICE40... :D
Sep 07 23:17:47 <m_w> I would like to move onto a Linux capable risc-v board soon
Sep 07 23:18:01 <m_w> the picorv32 does
Sep 07 23:18:27 <m_w> https://github.com/cliffordwolf/picorv32
Sep 07 23:18:36 <tlwoerner> cool!
Sep 07 23:18:48 <m_w> I actually got this to work
Sep 07 23:19:01 <tlwoerner> which board? my BlackIce board just arrived yesterday
Sep 07 23:19:21 <m_w> the code space was limited but I was able to use gcc and blink leds on the ice40 eval
Sep 07 23:19:40 <m_w> I used the 8k
Sep 07 23:20:09 <m_w> a little bird told me that the 4k actually has 8k cells in it, it is just blocked by the vendor tools
Sep 07 23:20:19 <ds2> hahahaha
Sep 07 23:20:23 <tlwoerner> figures
Sep 07 23:20:36 <m_w> so if you use icestorm you get 8k on the 4k chips
Sep 07 23:20:42 <m_w> like on the beaglewire
Sep 07 23:21:03 <m_w> which I should launch next huh?
Sep 07 23:21:25 <nerdboy> what did you launch just now?
Sep 07 23:21:33 <tlwoerner> nice
Sep 07 23:21:48 <ds2> you need to launch self modifying HW that can control a PnP and an oven }:-)
Sep 07 23:22:04 <ds2> HW needs to be able to self propagate
Sep 07 23:22:42 <nerdboy> skynet baseline?
Sep 07 23:22:55 <tlwoerner> m_w: http://ca.mouser.com/ProductDetail/Lattice/ICE40HX8K-B-EVN/?qs=ooqgTKD20drSds2K%2FEAnQg%3D%3D ?
Sep 07 23:23:08 <ds2> :)
Sep 07 23:24:20 * tlwoerner needs to figure out how to do IRC on my chromebook :-)
Sep 07 23:25:20 * ds2 needs to figure a solution for the next Linux laptop before the current one completely dies :(
Sep 07 23:26:34 <tlwoerner> ds2, yea... me too
Sep 07 23:27:01 <ds2> tlwoerner: know of ones that will painlessly install? apparently the recent intel chip based ones are broken left and right :(
Sep 07 23:27:04 <tlwoerner> i actually _like_ my chromebook: small, flip, touchscreen
Sep 07 23:28:44 <tlwoerner> i haven't tried linux on mine yet, i don't like to admit it out loud, but i actually don't mind CrOS, it's grown on me! but i did put it into "developer" mode, so at least i have access to a "real" shell and can ssh from there
Sep 07 23:28:48 <nerdboy> tlwoerner: freenode web is about it
Sep 07 23:28:58 <nerdboy> no irc and no imap on chrome
Sep 07 23:29:21 <nerdboy> feel free to write the missing chrome apps though
Sep 07 23:29:54 <tlwoerner> nerdboy: okay, worth a try. i had found a chrome extension, but wasn't too happy with it
Sep 07 23:30:00 <nerdboy> chrome is based on gentoo so how bad can it be?
Sep 07 23:30:05 <tlwoerner> then again, maybe i just don't like IRC enough... haha
Sep 07 23:30:12 <nerdboy> except for the apps they won't write
Sep 07 23:31:27 <tlwoerner> m_w: is that the eval board you tried?
Sep 07 23:31:46 <m_w> tlwoerner: yes sorry
Sep 07 23:32:06 <tlwoerner> m_w: i also ordered one of those 8k ice boards from olimex. figured i should throw them some love too :-) haha
Sep 07 23:32:57 <m_w> good idea, they do good stuff
Sep 07 23:33:34 <tlwoerner> oh! clifford wolf is the same guy behind the blackice! (?)
Sep 07 23:33:58 <m_w> got a link?
Sep 07 23:34:05 <tlwoerner> http://hamsterworks.co.nz/mediawiki/index.php/MyStorm_Blackice
Sep 07 23:34:19 <tlwoerner> oh whoops, my bad
Sep 07 23:35:01 <tlwoerner> icestorm are the tools, blackice is the board
Sep 07 23:36:52 <m_w> Mike Field is the guy it seems
Sep 07 23:37:22 <tlwoerner> right, Mike Field is "hamster", the fpga dude from NZ
Sep 07 23:38:01 <m_w> nice board though
Sep 07 23:38:02 <tlwoerner> http://hamsterworks.co.nz/mediawiki/index.php/FPGA_Projects
Sep 07 23:38:27 <tlwoerner> we just need a version where the STM32 is swapped out for an E310 :-D
Sep 07 23:38:30 <m_w> busy little beaver ... er hamster
Sep 07 23:39:00 <m_w> you know I thought about doing something like that
Sep 07 23:39:10 <m_w> ice40 + fe310
Sep 07 23:39:29 <tlwoerner> sweet!
Sep 07 23:40:15 <tlwoerner> maybe poke the blackice people (Ken Boak) and see if they're interested
Sep 07 23:40:29 <m_w> now let make up a catchy name first
Sep 07 23:40:32 <m_w> lets
Sep 07 23:40:39 <tlwoerner> Ken Boak <ken.boak@gmail.com>
Sep 07 23:40:47 <tlwoerner> BlackFive
Sep 07 23:40:55 <m_w> nah
Sep 07 23:41:06 <tlwoerner> IceFive
Sep 07 23:41:10 <m_w> meh
Sep 07 23:41:28 <tlwoerner> ice45
Sep 07 23:41:48 <m_w> :-/
Sep 07 23:41:49 <tlwoerner> ice40-five
Sep 07 23:42:33 <m_w> https://en.wikipedia.org/wiki/Ice_V
Sep 07 23:43:11 <tlwoerner> that's not bad
Sep 07 23:44:48 <m_w> https://hackaday.io/project/26848-tinyfpga-b-series
Sep 07 23:45:10 <m_w> have you seen this guy ^^
Sep 07 23:45:11 <m_w> ?
Sep 07 23:46:34 <tlwoerner> crazy small!
Sep 07 23:46:43 <tlwoerner> no, hadn't heard of that project
Sep 07 23:46:51 <m_w> same size as the lofive
Sep 07 23:49:24 <tlwoerner> wow! could you squeeze an e310 on a tinyfpga-b ?
Sep 08 00:04:14 <m_w> I dunno
Sep 08 00:04:28 <m_w> probably would have to make the board a little bigger
