‘Tis the season for holiday hacks, and [Ben Emmett] is here to remind us that we don’t necessarily need a fancy microcontroller in order to make flashy fun things happen. …read more Continue reading Flashy Paper Christmas Tree Does It With a 555
These days, oscilloscope hacking is all about enabling features that the manufacturer baked into the hardware but locked out in the firmware. Those hacks are cool, of course, but back …read more Continue reading Double Your Analog Oscilloscope Fun with this Retro Beam Splitter
For serious high-voltage plasma, you need a serious transformer. [Jay Bowles] from Plasma Channel is taking his projects to the next level, so he built a beefy 6000:1 flyback transformer. …read more Continue reading Pushing the Plasma Limits With a Custom Flyback Transformer
