Here’s a cool DIY on how to build your own laptop using a microcontroller and an LCD. Well we should really call it, “MCU Laptop” but it’s a great exercise for anyone learning computer hardware.
Ever thought to yourself, “Hey, I could probably build my own computer if I really tried.” Or maybe, “Man, I really need a laptop with an embarrassingly low-resolution display, a processor that goes at 256 Instructions/sec, and I’ve

Here’s a tight ass robot!
While simple yet robust behaviors can be achieved without a model at all, here we show how low-level sensation and actuation synergies can give rise to an internal predictive self-model, which in turn can be used to develop new behaviors. We demonstrate, both computationally and experimentally, how a legged robot automatically synthesizes a predictive model of its own topology (where and how its body parts are connected) through limited yet

Wow, check out this awesome homemade balancing skateboard. As a skateboarder myself, this is way too cool…
It’s very similar to a snowboard to ride, requiring no user input other than the movement of your body mass. Leaning forwards and backwards controls the velocity and moving your weight from heal to toe controls the turn radius. It’s easy and very intuitive to ride.

Check out this octopart search engine for electronic parts. It seems to searching mouser, digikey, and other major electronic part companies for stuff. The creator dropped out of school to make this so everyone please take a look! P.S. I couldn’t find any Make controllers, Cublocs, or any controllers that are not being sold through the major suppliers… (maybe they can add them…)

Wow, check out the wifi-robot from wifibot.com!
WiFiBoT comes to fill the gap between the simple toys and the sophisticated but expensive robots that can be found today in the market. In our platforms you will find the right compromise between cost and sophistication so you don’t overshoot your needs with any complicated gear
Here’s a cool little project that stores data into an SD card using solar power.
After some prodding from customers and an upcoming prototype run I decided to throw in a little breakout board that would allow 2 solar panels to be connected in parallel to a 7805 linear regulator. An LED was added with a switch so the user could identify when the board was making power. These boards can output 8V@300 mA and should easily provide more than enough votage and current to charge the batteries. This setup
Here’s a cool blog I came across on our new wagg.it site. It’s a custom application that will send email containing current external IP address to a specified email address automatically at set intervals.
Why do you need this?
I used to work as a network administrator at a company and had issues with DDNS (dynamic DNS) addresses where the domain name can change. We u
Check out this PIC based bluetooth accelerometer that you can use for your future wireless accelerometer applications.
This is a small wireless sensor platform providing a bluetooth SPP link to three axes of accelerometer data. The accelerometers are sampled by a PIC microcontroller (onboard ADC) at roughly 100Hz (rate can be changed via firmware). Data from the ADC conversion is sent to a remote computer using the PIC’s UART in conjunctio
Check out the new RFID tags that are smaller than human hair from Hitachi Japan!
The minute devices measure just 0.05mm by 0.05mm (0.002×0.002in) and to the naked eye look like spots of powder.
They are thin enough to be embedded in a sheet of paper, Hitachi spokesman Masayuki Takeuchi says.
RFID tags store data about the objects they are attached to, and companies are vying to create increasingly tiny versions.
Recently, Hitachi unveiled another RFID tag, the
