Новини світу мікро- та наноелектроніки

I got into kart racing a few years ago and got pissed off at how expensive dataloggers were($500++), so I went to build one, only to find no ones ever really released many if any public libraries for gps lap timing.

So I made one, and then I needed a logger for it, so I made that, then I needed a case, and made that too, and recently cive-coded a data-viewer but that's another rant (20yoe swe)

Well all of that took a year to perfect, the laptiming is within 0.002s of the official laptiming, I can do track/course selection, laps, pace, and even split-timing on-device.

Now sure, it logs data, but it's not a datalogger without more data. Most other sensors are piss easy to implement... Engine rpm tho... My god what a nightmare

I'm a software guy, never made hardware before, barely have any idea what I'm doing but by God I'm making progress. Right now I'm dealing with SD cards being corrupted so I finally gave in and bought a scope to learn more, managed to build a drastically cleaner circuit than I had before and I got some hope.

(Yes vibration kills, but this is a new problem with adding the tachometer, and I haven't even gotten to testing that on track yet)

(I must do this weird capacitive dance like the commercial ones do, but I also don't have one to take apart so we're gonna just keep winging it baybe)

No I don't want to talk about how much money I've spent at this point, I'm making a damned open source, and cheap, datalogger so help me God

I've got GitHub links for everything but don't wanna get yelled at dropping links in a first post or something

I probably should have went to school for this but hey, I've gotten this far on nothing but hopes and dreams

Hi Reddit,

While reading the Charles Petzold's great vulgarization book CODE : The Hidden Language of Computer Hardware and Software I told myself that it would be a cool educational project to animate the book schemas to vulgarize how computers work down to the transistor level.

So I created an electronic circuit engine to help discovering how electronics and computers work. You can check the demo here.

This is a starting open source project and all comments and feedback are very welcomed !
