  • Custom PCB's Are Here!

  • Received the custom PCB's from OSH Park and they seem fantastic! The plan is to assemble a couple more prototypes and make sure the PCB version works as well as the breadboard ones. I don't anticipate any issues but will see if Mr. Murphy has found a...
  • Powering the beast

  • Following from the change from sunglasses display to a 2.5" S-Video LCD...Power: The LCD requires 7-12vdc. The Pi delivers 5v from pins and that's confirmed by testing to not be enough. With the dev SKROSS Reload 5 I have 5vdc 1.5amp output. This runs...
  • BOM coming along.

  • Working on getting BOM in. Couple of notes:The RC transmitter and receiver can be whatever you have. The battery, wiring, connectors should all be rated for whatever motors you pick up, as well as the speed controllers. My speed controllers happen to...

  • Proof of Video Life

  • Today's update is one of those "it's really coming together" type updates. Since you're reading text and you'll probably scroll down anyway, let me blow the surprise: it's VGA and NTSC test patterns.  On a 64 macrocell CPLD.  From a single,...
  • Step 3: build an amplifier.

  • I've got a small pile of LM386 amplifiers that will never see the light of day. Way back when, I loved building little amps for things and somehow got it in to my skull that I should have stock of these sitting around. Along with some LM741 op-amps....

  • Inventory:1. Motherboard: Gigabyte GA X99P SLII found that the biggest filter in motherboards is the amount of memory they can support. I was pretty certain that I wanted a motherboard that would support up to 128 Gb of RAM. The next biggest filter...
