This past winter I designed and constructed a stereo vacuum tube amplifier based off of the TubeLab SimpleSE design. Since many people asked about it at Maker Faire Detroit, I thought I would post a link to the build photos and some more details. Check out the build album below! Some more technical details: Preamp:

DC-DC converters are widely used components that convert DC power from one voltage to another, producing a regulated output voltage. These devices are used in many electronic products, including laptops, mobile phones, and instrumentation. Like any device, DC-DC converters need to be characterized by manufacturers and by engineers evaluating them for a design. Given the

Watch signals propagate through basic digital circuits. Emulate any two-input logic gate using just one rLogic board and one jumper. To order rLogic+, the breadboard compatible variant, simply order normal rLogic. When the survey is sent out you will indicate which you would like. rLogic is a basic breakout board for the Fairchild Semiconductor TinyLogic®

The fact of having a CNC available at home gave me the freedom to build stuff more easily and quickly than before. Without this machine parts would take some time to manufacture and most likely would not end so perfect. This caused new ideas to be easily implemented. This was one of those ideas that

Northwestern University researchers are the first to develop a new solar cell with good efficiency that uses tin instead of lead perovskite as the harvester of light. The low-cost, environmentally friendly solar cell can be made easily using “bench” chemistry—no fancy equipment or hazardous materials. “This is a breakthrough in taking the lead out of
