Motorola didn't end up so great because of him either.

It's surprising that the FDA doesn't require that as part of their certification procedure.

Tarnovsky has given several really great talks at Defcon: https://www.youtube.com/watch?v=kh238PUqz3I He goes into a lot of technical detail which is great. I'm a big fan of his work.

I submitted this 11 hours ago and it got zero votes during the first several hours. I thought it was lost to the depths of HN, how did people find it so many hours later?

Well, I want to be really good at electrical and computer engineering, so I wanted to work on problems relevant to that. If I stayed at Soylent, I'd have devoted all of my time to becoming really knowledgeable about nutrition, a field

I offered help with electronics projects and had maybe a dozen sessions. I charged the default $1/minute and really enjoyed it, because I got to hear about all kinds of cool things people were working on, and I got the satisfaction of

Reminds me of the Zipit Z2, which was a handheld messenger toy that could be hacked to run linux: https://mozzwald.com/zipitz2 Not as much power as an RPi though.

He actually mentions that solder is not a good mechanical connection and said he used solderwick to reinforce the patch joints.

Interesting. I guess maybe you could repair a multilayer board that had a hole in it by milling down the edges of the hole in kind of a stair-step pattern to expose each inner layer and then attach your patch. That would be quite a job.

Wow, this is fantastic. This can only be done on 2 sided PCBs, since you couldn't connect the inner layers of the PCB patch back to the original PCB. But it reminds me of Kintsugi[0]. Perhaps if he used a solder that had gold mixed in

There's lots of tutorials out there for this kind of thing, and looking at other people's project logs (like this submission) is good. I like to use OSHPark to get my PCBs made, but some people also like ITead Studio. Personally,

I've seen that same oscillation problem at the end of Flight 2 with some of my vehicles in Kerbal Space Program before. It's funny to see that on a real vehicle.

This reminds me of work by David Cope called Emily Howell: http://artsites.ucsc.edu/faculty/cope/Emily-howell.htm There is no source code that I could find on that project, so I'm looking forward to checking

Boy, hardware is hard. I've designed lots of small things, but never anything this complicated or mass produced. There are so many things you can get wrong, so many little adjustments that need to be made. One of the reasons I've

Could that last step be considered a kind of Levenshtein distance measurement?

Catadioptric omnidirectional vision is a really cool technique. I've always wondered why it isn't seen in the wild more often. I first saw this technique being used in Robocup Midsize League [1]. There's lots of good papers o

Sorry about that, stupid DreamHost disabled my site because they detected high load. I don't have any of my credentials with me, so it'll be a couple hours before it's back up. Use the Google cache for now. Sorry :/
