The details behind this connector was unknown until recently.  Here is some info on the chip that is inside. Ramtin Amin has recently taken reverse engineering to the next level by first making a breakout board. It was made to inspect the main WLCSP
 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
 This HCCI Engine Controlling Raspberry Pi setup reads in 240,000 samples per second. I had never heard of an Homogeneous charge compression ignition (HCCI) engine other than a diesel that simply compressed the air fuel mixture till combustion although I guess that is what some of those cars from the 80 were doing when they would continue to run after the key was turned off? I had always
 These Internet Controlled Robots are not available to play with all the time but if you keep an eye on the Twitter channel you will have a chance to have a look and give them a try when they are online next. “I only put together one robot kit previously, then these two robots both started as Activity Bots. I hooked up a Raspberry Pi with an HD
 It isn’t a simply task to make a self balancing anything. But if you are thinking of taking on the challenge XenonJohn has documented his design details for this Self-Balancing Raleigh Chopper that could give you a head start. “Data from the IMU is read by the Arduino Mega 1280. I use a Mega 1280 because they are a lot cheaper online than the 2560, and about
If you think the price of 3D printers is hitting the floor check out what Mikelllc built for $60. About 80% of this EWaste 3DPrinter is recycled computer parts which is abundant and readily available. “First of all, we learn how a generic CNC system works (by assembling and calibrating bearings, guides and threads) and then teach the machine to respond to g-code instructions. After that, we add a
