HDMI current booster fixes Raspberry Pi video instability

Orlando Cosimo with Creativity/Design blog was experiencing instability problems with the HDMI output on the Raspberry Pi which are typical when using an HDMI to VGA adapter. He devised this solution using three resistors and an LM317 voltage regulator. Orlando states, “This addon hardware extends a past project and it allow to increase the flow […]

R-Pi as Arduino HDMI server

jokkebk over at Code and Life has developed a simple “HDMI server” for the Raspberry Pi that uses pyserial to receive commands over Pi’s serial interface, and pygame to display graphics primitives according to those commands. An Arduino client was written to send these commands to the Pi, drawing a string of blue rectangles to […]

Workshop Update for July 5th, 2012

Today is Workshop Video Thursday so we spent a lot of time in filming and editing. We still haven’t found a great solution for the screen capture software. Firmware development took a hit today, as we wasted most of the time following wrong assumptions. While implementing the final “menu activated” function, we somehow broke the […]

Another way to store your electronics components

WORKSHOP VIDEO #07: Video editing workstation build

Making workshop videos is a lot of fun, but editing the high-def video is painfully slow on even our best CAD workstation. We set out to upgrade one workstation to run Adobe Premiere with a budget of about 500 bucks. It’s not a killer gaming rig, but it encodes videos in minutes instead of hours: […]

Arhi’s transitor tester built into a case

Arhi built a transistor tester, a tool that recognizes and measures most common semiconductors. We’ve been following this project closely for the past week or so. After building a perf-board version, he made this version to put in a case. Check out the video of it in operation above. Via the forum.
