Occasional reminder that I have moved my main account to:


@Zach @nonlinear Thanks. I figured I would lose some followers. I will probably boost my posts on my previous timeline for now. I figure people that are interested will come along, either now or later.

Will keep @nonlinear for backup

Well, it's a clean as it's going to get. Behold! The Lab.

Amazing results today. @scanlime wrote a LED panel driver design for the iCEBreaker today using all open source tools in icestudio! (in an over 8 hour marathon stream) Looks amazing! :)

Still live and playing post-punk, coldwave and some goth rock tracks on #tilderadio - the all new streaming radio service of the tildeverse! Will be around for the next half hour or so, hope you can tune in! 🎶🐱💕
