Fresh hacks every day
Here’s a no-PCB Arduino that doesn’t obscure the DIP footprint of the AVR chip. It’s built on an ATmega88 chip, and includes a programming header, reset button, a couple of filtering caps, and an LED. This is modeled after the Lilypad hardware, and fits nicely on top of the plastic case of the microcontroller, allowing it to be used in … Read the rest
The most recent installment of [Dino Segovis’] Hack a Week covers the construction of a simple NPN transistor audio preamp. Some time ago, he built a small audio amplifier using an LM386 which worked well, but didn’t quite get his music as loud as he would like it. He decided to build a preamp to complement his amplifier, and … Read the rest
Everyones favorite site, Instructables.com, has announced a big move. They have joined Autodesk along with the same team that is doing Autodesk 123D,
Autodesk is a great cultural fit for Instructables. They make tools for creative people: they’re the world leader in 3D design, engineering, and entertainment software. Even if you don’t recognize the name Autodesk, their software has
“Wednesday, I was arrested and sent to jail,” is what your blog might say if you decide to try and duplicate this project. You may, however, be fortunate to be still writing your blog, as ATTEMPTING TO BUILD YOUR OWN REACTOR can be quite dangerous. That’s what [Richard] did using household items such as clock fingers for Radium, and … Read the rest
[Alex Busman]‘s first foray in iOS programming looks like a pretty useful tool. He came up with Ohm Sense, an iPhone app that will take a picture of a resistor and calculate the value based on the color bands. It’s a great tool that we wish we had when we were starting out. At 99 cents, the app is … Read the rest
