Low Cost Digital Microscope
With some of my other projects I’m working with fairly small electronics components so I ordered a low-cost digital microscope off of eBay. I paid about $40 for a 0-500x digital microscope. It’s really 0-400x with ‘digital zoom’, a worthless feature but otherwise it’s a pretty cool tool and toy for what it is. The […]

Making Night Blades for R/C Helicopter
I’ve been thinking of making night blades for my R/C helicopter. Back in 2003 I made a set of wooden night blades for my Raptor 60 using RGB (Red-Green-Blue) LEDs and an Atmel AVR micro-controller to make them change colors and shift patterns. The blades were pretty simple but they worked. I even slapped together […]

Well, I went and did it. I broke my HTC Google Nexus One’s digitizer by accident and now I have to replace the digitizer. I’m not quite sure how it happened. Perhaps in my pocket with a flashlight, or one of the few times I dropped it working on a friends car but the digitizer […]

Very Large Home Made Lithium Polymer Battery Pack
I was sent this video from Chris Luxembourg called BATTERY OR WELDING MACHINE. (He has since closed his youtube account and the videos are no longer available!) He built this monster Li-Poly pack for his Lowracer project, a hybrid/electric super-efficient bicycle. Bicycle may not be the appropriate name for the thing. Looking at some of […]

Some Explosive High Voltage Capacitor Discharge Videos
Posted on October 9th, 2010 in Custom Projects, High Voltage
I grabbed up some of my high voltage videos from my laser site and compiled them into a compilation for you to view. A quick description of the capacitor discharge setup follows. Power Source: 15kV 30mA Neon Sign Transformer using a full wave bridge rectifier. Each stage was built of 30 1n4007 diodes wired in […]
