The silicon wizards at Flylogic have certainly posted an interesting chip this time around. The Intel 4004 was the first widely used microprocessor. The logic gates are much larger than you'd find in modern chips. The unique feature is that each gate is designed to make the most efficient use of the silicon instead of the standardized shapes you find now. They've uploaded a full image of the … [Read more...]
30′s style regenerative receiver

[Des] sent in this really cool writeup on building a Regenerative receiver using VFDs. Regenerative receivers are basically short wave radio receivers that use positive feedback to more finely tune the signal. Though they can be built with modern components, [Des] wanted to try to make something that not only looked like it was made in the 30's, but actually used the same technology. He utilized … [Read more...]
NoiseAXE minisynth

The NoiseAXE is a miniature synthesizer based on the Picaxe 08M microcontroller. Its operating principle is fairly simple: a conductive stylus touches the leg of one of eight resistors to play one of eight notes, while a photoresistor controls the amount of modulation, creating a variable vibrato effect. While the synthesizer's output is rather limited (the NoiseAXE isn't exactly a Yamaha … [Read more...]
Atari Xbox 360 controller

It's amazing what [Ben Heckendorn] can manage to crank out in just five hours. This time it's a wireless Xbox 360 controller stuffed inside an Atari 2600 controller. The guts are from a Guitar Hero 3 controller. It's a fairly compact board and [Ben] used thin ATA wire for the connections. While it doesn't have all the buttons of a true Xbox controller, this 3600 controller has enough to make it … [Read more...]
