Intructables member Alex the Great has a clever Awesome LED Cube project. Use the cube to slow, stop, or reverse time, or even turn ordinary technology into transformers. Your choice. This project looks like a great way to introduce kids to a number of valuable skills we have covered here at Make: Online, such as […]

From the MAKE Flickr pool Feurig etched a well-planned fish-shaped circuit to hosts a slew of pink LEDs as scales. Great work – though it would be nice to see all those lovely copper traces exposed in the final product. A lot of work goes into designing circuitry and etching your own provides an excellent […]

While developing the Roboduino, Scott had to calculate how many amps his project could deliver to attached motors. He wrote up his findings (and how he arrived at them) as a helpful article – As a review, the total heat generated by the regulator is just the energy in minus the energy out. This is […]

From the MAKE: Flickr pool Anachrocomputer shares with us this handmade piece of digital days gone by – Top view of the 300 baud acoustically-coupled modem that I built in 1984. I made the double-sided PCB myself with an etch-resist pen (Dalo pen) and some rub-down transfers. The main chip is the Motorola MC14412V single-chip […]

Sayeth the animated, wraithian lab coats at Evil Mad Scientist Laboratories (think: Santa’s worshop, only for Halloween, and evil!): Here’s an inexpensive electronic circuit that you can build to put in your Jack-o’lantern. It provides power to drive a few LEDs at night, and automatically turns them off during the daytime. It’s a simple and […]

If you’re interested in building an analog synthesizer then the VCO (voltage controlled oscillator) circuit is the best place to start. Oscillators form the core of the instrument, generating basic waveforms which are then shaped and shifted by accompanying components like LFOs, VCAs, and filters and then delivered to our ears as tasty electronic audio […]
