This is a really interesting article about removing rust via electrolysis. I know a lot of our readers like to re-use and recycle old parts, and sometimes that involves removing a lot of rust. There are various obvious methods of rust removal, but these methods are unsuitable for very old or valuable artifacts as they […]
Evil Mad Scientist Labs introduces the Mignonette AVR gaming platform, developed by Rolf van Widenfelt, Mitch Altman, and EMS’ own Windell Oskay – The Mignonette is designed to be easy to assemble, and uses a rather minimal set of components– the AVR microcontroller, the LED display, and a pair of ULN2003A transistor driver chips for […]
(photo by Scott Beale / Laughing Squid) Sean O’Steen illuminated his love for the Twitter Fail Whale by rendering the lovably iconic mammal in LEDs on a Peggy board. Wow – people love that failing whale! (Personally, I wish whales the best of luck in all their endeavors ;) – LED Whale Love on Flickr […]
‘Stringstetcher’ didn’t want to spend a lot of time, or money, making a commercial size food dehydrator. The solution was to use “Sonotube” that is readily available in hardware stores. I would be a little cautious with the heater up against the tube, but it is low temperature and only takes about 3 hours to […]
This video isn’t a how-to, but it doesn’t look all that hard to build. I don’t think that completely open and rewound transformer is too safe. You may want to enclose it a bit better if you try to make one for yourself. I had a dead microwave oven transformer so I sawed off the […]
If you’ve had your Maker’s Notebook for awhile, you’ve likely ended up with a tassel where the bookmark used to be. The ends of the ribbon markers are not finished or glued and so they fray over time. This is easily fixed. Just dab little beads of white glue along the leading edge (after trimming […]
From the MAKE Flickr photo pool Funnypolynomial shares his creative take on the LEDkit solderless clock project, using a clear cube enclosure for a multifaceted display – very cool idea! (Hmmm, wonder how this might work out on a sphere …) – Cube Corner Clock – 7:36 on Flickr LED Clock Kit -Red
