Dragao has a Sonic Cartridge that had some invalid instructions that would cause the game to crash at a certain point. The solution wasn’t to find a replacement game at the local flea market, he Resurrected the Sega Cartridges using some old Computer Chips. The game was originally loaded on 16 bit memory chips, not having any of these handy from the donor computer motherboards he piggy backed 2Â
Bob Johnson completed his DIY Water Level Sensor project. It can sense 4 levels of water, the results are transmitted using some Xbee devices. “The distance from my barn to the house is over 700ft. I used a 2.4Ghz yagi to send the signal to the house. This works great and no outside antenna is required at the receiving end. I have tried this setup at much smaller distances, and
When your RC plane flies out of transmitter range some of them are setup to start a slow bank so that it hopefully flies closer to you and you can reacquire communication. What if that fails and the plane comes crashing back to earth? This Lost Signal RC Alarm & Lost Plane Finder project will help you in this case. When your transmitter is not connected the buzzer will
If you are looking to build a new project, this DIY AC Watt Meter would make for a useful device that can be added to your test bench. “The microcontroller of the wattmeter is PIC18F252. Basically it reads the voltage and the current and calculates the RMS voltage, the RMS current and the average power. Then it interfaces with the LCD and shows all these values. It has a
 If you want your valentine to work for their candy hearts why not build them a slot machine to let them win them. I have seen little bits before but this is the most complex device I have seen built! “Try your luck with the littleBits Slot Machine and win a handful of candy hearts for your special someone. This slot machine operates just like the real thing.
Remember the Nokia 3310 Phone Multimeter that we saw last month? Looks like there has been some massive work on the project. It is complete and looks like it works great. It’s fantastic to see a resistor plugged into the bottom of a phone! Link with steps to build your own.
 The ESP8266 is quickly becoming a very popular chip, I am sure this is mostly due to the dirt cheap price point. If you are adding this to a battery operated application you might want to drop the power consumption as low as possible. There are many things that can be done to do this, removing the indication LED is the first obvious step. Jagenberg.info has done some work in
