Fresh hacks every day
Brushless motors and the way in which they are controlled can be a bit of an enigma to those just starting out in hobby electronics. [Andrew] from spingarage thought it would be helpful to put together a quick tutorial showing how he built a simple brushless motor controller in about a day’s time. He constructs everything on protoboard from components … Read the rest
[Wayne] wrote in to share an item he just finished working on, an I2C GPS shield for the Arduino. While other GPS solutions have existed for quite some time, his caught our eye due to its feature list.
The shield removes a good bit of the hassle associated with parsing raw NMEA data from traditional GPS addons. … Read the rest

However, unlike us, [Chris]‘s feline buddy is too preoccupied with cat stuff to bother flipping off the faucet after its use. As it turns out, this was an excellent opportunity not only for [Chris] to flex his project muscles, but also to lay … Read the rest
This robot can be controlled from the terminal window of your computer. You can see a manilla-colored board mounted between the wheels. This is the RF receiver which has quite a long antenna that we’ve cropped out to get a better look at the bot itself. [Ashish] picked up an RF transmitter/receiver pair for about $4 and after the break … Read the rest
One thing we learned by watching [Alton Brown] on all of those Good Eats episodes is that a multitasker is way better than a unitasker. [Joost] is thinking along the same lines by taking a fantastic tool and adding a useful function to it. His software project turns a USB Saleae Logic Analyzer into a signal generator.
There are … Read the rest
This weekend project will tell you when you’ve got something new to look at on your Facebook page (translated). The yellow flag on the side of the mini-mailbox automatically goes up, alerting you to your recent online popularity.
[Rocco's] craftwork on this project is fantastic. We love the scale, the colors, and especially the artificial grass that adorns … Read the rest
[Miceuz] just finished his first surface mount electronics project. It’s a pink noise generator that is used for testing audio equipment (scroll down that link for the English version of his writeup).
Pink noise is somewhere in between red noise and white noise. Didn’t realize there were more colors than just white when it comes to noise? The benefit of … Read the rest
