FCB1010 vs PU-2: Why do it?

Posted on 2011/09/26 by rt

While waiting for parts (I do have to get a better inventory “system”) to complete the Betas for the PU-2, I went through a short period of discouragement. It’s hard to stay fully motivated when the project is bogged down … Continue reading →

PU-2: A batch of Beta

Posted on 2011/09/21 by rt

I’m getting comfortable making the PCBs for the PU-2. This is what a batch of 5 boards looks like, fresh out of the etching tank. I still have to drill the 800-plus holes and solder everything… patience… This is what … Continue reading →
