Fresh hacks every day
Every year, [ilektronx] and a few other guys get together and compete in a ‘no holds barred’ pinewood derby for kids of all ages. Of course this results in an immense amount of engineering to push a wooden block with wheels down a track, and [ilektronx]‘s car is no exception. He won the competition with electronics from a remote control … Read the rest
[Paul Stoffregen], the brains behind the popular and very capable Arduino-compatible Teensy development board, has offered his contribution to the explosion of ARM-powered boards with the Teensy 3.0.
The original Teensy is an AVR-based development board that goes far beyond the official Arduino offerings. The new and improved Teensy 3.0 improves upon an already wonderful platform with a 32 … Read the rest
If you’re looking for a DIY amplifier project made with a minimum of parts, this is the build for you. [Rouslan] created a 70 watt class D amplifier using an ATtiny45 and just a few dollars worth of additional components.
A class D amplifier simply switches transistors of MOSFETs on and off very rapidly. By passing the signal produced … Read the rest
We see projects here all the time that blend computing with the real world. Some people are naturally stronger on the mechanical end of things, whereas some are better with electronics or coding. All three specialities can be needed depending on your project. If your weakness lies in making a computer do your bidding, I might suggest that the Python … Read the rest
[PC486] wanted to add Bluetooth to a simple shelf stereo system. But if you’re going to go wireless, why not develop an all-in-one solution. His adapter turns on the stereo and feeds it audio all from a smart phone.
This is his roommate’s hardware so cracking it open and grabbing an iron wasn’t really an option. He needed a way … Read the rest
