• breadboard build Recently I watched this talk on Vector retrogaming from the 32c3. I've had a vectrex collecting dust for the past few years and thought it'd be cool to try to get some non-vectrex games running on it as seen in the talk.I've followed a schematic i found posted in the issues of the github for the project. I made some comments as i went through the build, trying to get everything running. I've got it connected to a retropie built on an RPi2. I exited emulationstation compiled and ran a modified MAME as seen here.It was fun getting this running. It's working great most of the time, i have a slight issue ...

  • Kodi Controller Support on Retropie I'm in the process of putting together a few retropies as gifts. I installed kodi and setup menu art just as described here. I then installed Plexbmc following this guide. If you're going the manual route, be sure to grab the latest zips off GitHub. They're available here and here.The video was great, i caused a bit of a headache a couple times while copy pasting by inserting carriage returns where they didn't belong. dos2unix cleared that up. I don't remember 100% because it's been about a week since i completed this, but i also had an issue with conflicting xboxdrv startups. The retropie setup script places a line in rc.local to ...

  • Fan controller Had some time to breadboard tonight.Current issue:When pwm is fully off the mosfet doesn't switch fully off. Disconnecting MCU allows full off but high freq (32kHz if i'm reading that correctly) switching 90% off only seems to drop the voltage to 10-ish volts (12v source). The Off voltage stayed the same even under heavier load. It's now running four fans at .6 amps each.I think i may be switching too fast. I had cranked the pwm frequency to get it out of hearing range. I've got to see what i can lower it to.Scope reading while MCU outputs below signal.Scope reading at lowest knob setting.   Breadboarded!

  • Let there be SITE! So at least the site exists and the domain is working. I'll dump more into the site as often as i have time to do so.
