Adiabatic posted:Arduinos are sooooooo easy to use. I didn't know how great I had it until this class made me learn ARM on a discovery board. It takes hours to do something you could make in ten minutes with an Arduino. Yeah I have a few discovery boards, I wrote a tutorial on how to set them up on Mac OS X, my toolchain is ready to go and even then they're all sitting in my drawer as I fart around on $1.70 Digispark clones. The Arduino toolchain is so nice to just hack out stuff even if you're giving up a lot of headroom to the bootloader and the IDE sucks. One day I'll actually make something useful. Current project is trying to figure out how to interact with an RS232 chip so I can speak SSM2 over an OBD port to my Subaru and pull a variable. edit: there's an arduino core provided by ST for most of the discovery boards so I guess I could still sorta reuse them if I wanted to write my own drivers for 99% of the nice hardware that the discovery boards have and the arduinos don't.

Just got back from The Martian. Best movie I've seen in a long time. Had several nerdgasms throughout, and was very happy about how faithful they were to the source material.

Got home from work. Opened my bedroom door. Grey blur shoots out of the room making pissy cat-like noises, and heads for the litter box. I loving swear he was out of my room when I left. And I know drat well the door wasn't closed all the way (guessing the a/c coming on pushed it the rest of the way closed). And even after that, he's still curled up under my desk.... rimming himself.

Holy poo poo. That speeduino is awesome. I'm going to see if my friend with the 16v gti will let me use it for an experiment. Hell, I might buy a couple, one for the Mazda, and one for the 600r ninja motor I have...

It's probably worth mentioning that the name "Megasquirt" came from the original prototype - an Arduino Mega fuel injection (fuel squirter if you will) controller - MegaSquirt. the ATMega2560 chip they use is more powerful than an awful lot of ECUs. To add to gently caress Cancer chat, dad's best friend and coworker (2nd in command) of 15 years passed away this afternoon. Two months ago he was fine, started having some migraines, went to the doctor and rushed to hospital 3 weeks ago with the MRI showing 13 tumors in his brain. They got the largest one out, size of a golf ball, but it never looked good... They gave him a week two weeks ago. It's just like him to have to prove them wrong. I had the privilege of working with him a few times, and I've known him nearly as long as I can remember - he was a top bloke. 20 years in the navy, one of the kindest people I've ever met, and wit sharper than a katana. A month ago dad was discussing retirement plans with him... At least we got to say goodbye. gently caress cancer gently caress it so much

Depends what you want to do (the car stereo probably isn't exposing much that you can work with, but if you have a steering wheel harness or something you could probably splice into that). There's a few Arduino-style boards with Bluetooth support, but I haven't used them.

Arduino nerds, I was bought one a while back but have yet to look into what I can use it for. Could I be a complete dork and stick it between an audio system and something like a NES controller to select stuff onscreen instead of using the typically terrible remote/unit controls?

OK, I may need to post this in the new ECU/wiring thread, but all the discussion made me remember a sidelined project I have. I picked up an '88 Olds digital dash to potentially use in my '70 Cutlass. It's actually pretty simple. For the most part, it uses dicrete standard GM sensors: oil pressure and water temp are the usual sensors one would use for analog gauges, and the speedo is GM VSS. There is one exception. The tachometer is driven not from ignition pulses (as the analog version on this same car is), but from the ALDL data stream. I don't speak ALDL. I had a guyy lines up long ago to build me an adapter that would take in tach pulses form my HEI and then output a fake ALDL data stream with the RPM block having actual data. I was very poor at the time, and missed that opportunity. Does anyone here speak GM ALDL? I got a bunch of info from GM-ECM pages, but I can't wrap my head around it. My next best option is just wiring up a GM-ECM with the most minimal inputs necessary and stuffing it under the seat. That may be the cheapest//simplest way to go.

I just got back from watching The Martian, and I just loved every single second of it. Of course they had to leave out some stuff that would probably have taken way too much running time to do justice to, and even though there were a couple I really wished they had left in there (basically more of Watney's various mishaps), I can understand why. Matt Damon was spot-on as Watney, exactly how I imagined him from the book. Actually what I loved most about it (and about the book, which I read from cover to cover in a day and a half) was the sense of "science, gently caress yeah!" and the feeling that we can do amazing things if we just stop bickering and fighting, start working together instead. I hope the book and the movie will inspire more people to get into the scientific fields, and a likely very naive part of me truly hopes that we can finally give space exploration the funding it so desperately needs and deserves. Also, a hearty  at the council of Elrond thing with Sean Bean.

Matt Damon was spot-on as Watney, exactly how I imagined him from the book. I thought that the book did a much better job of explaining how and why Watney came to the conclusions he came to. It really showed the ingenuity of the man, and it's part of the reason why I liked him as a character so much. The movie seemed to gloss over a lot of this (and for good reason, you can't spend screen time explaining the molecular makeup of hydrazine) and just showed him getting to work, as if he knew what he was doing and had a plan all along. But the book really illustrates just how far into uncharted territory he is with everything he does. For being a PG-13 movie I'm really glad the first word Watney says is "gently caress" and the later on "gently caress you Mars"

Yeah, I think that you're always going to get cuts of detail like that. However, if they're sensible, the bluray release will have popups to say "hey, here's the science poo poo that's going on here".
