Len Bayles has designed a great looking Meter Clock which is based on the Atmel AT89C2051 microcontroller. The design is similar to the Multimeter Clock that I created. Len provides the code and schematic on his site so you can make your own. “The software in the microcontroller handles the count for the time. It “talks” to a 4 channel Digital to Analog converter to derive the voltage to position
Sparkmuseum user on Youtube demonstrates his Wireless Pan Tilt Project. It is so responsive that it looks like it is a wired connection but it is wireless. He is using an xBee to communicate the data generated by a Parallax Basic Stamp over to a Pololu servo module. Thanks for the tip John.
Looks like Microsoft is trying to make our lives a bit better with their new battery holder design. What is so cool about a battery holder that needs to be talked about? Well this battery holder can accept the battery inserted either way. I know so many people who just slot the batteries into everything and wonder why it doesn’t work… This device would solve this issue since it doesn’t
If you are looking to have a bit more fun with your Arduino why not use it to launch some model rockets! That is what the guys from NortHACKton did. They have a full schematic available on their site. Thanks Martin. “It’s a very simple little board, consisting of a driver chip and a relay and the connection to the dot matrix display. I chose to use the ULN2003 to
This article is for educational purposes only, ripping off a poorly created system is still theft. That being said we can learn lots about how not to create a card payment system. Koala from Because life is a hack was curious what made his laundry card payment system work, after cracking open the case he was surprised to see an EEPROM inside. Using a Bus Pirate and a Openbench Logic
Here is a cool battle between a Paintball toting Tank and the Paintball Sentry. Looks like the tank needs a bit more speed and punch to be able to be a contender. Thanks for the email Jeff. “I mounted a turret kit from our website to a Traxxas slash and pit it up against the paintball sentry”
Matt Meerian of Home Brew Electronics sent in this Electronic Bird Catcher project that he completed a few weeks ago. It is a device that was hacked together to catch a robin that was causing mischief around his new house. He tried a few simple methods of getting rid of the bird but they weren’t very effective. He decided to let some technology help him out, he designed a quick
