Searching the web for an RC(PPM) to FMS (Flying Model Simulator) USB interface i didn't find such a device for free and with interesting characteristics. For this reason i decided to start the developing of the FMSUSB. The name could be not so appropriate because this is an interface that converts the PPM signal coming out from the RC to a Windows Joystick, so it can be used not only with the famous FMS, but also with all the games that are allowing a joystick as an input. For example you can use your RC also to drive a car. Another interesting thing is that no extra driver is needed to allow this circuit to work on a Windows 2000 or XP system, really plug and play!!!
"The RFM12B radio is the FSK (frequency shift keying) radio that we use on JeeNodes, JeeLinks, JeeUSB boards. The radios are manufactured for use in the 434 MHz & 915 MHz bands for use in US and Australia; and 434 & 868 MHz for use in Europe."\n\nPricing is about $7.00 a unit

"This DC-to-AC inverter schematic produces an AC output at line frequency and voltage. The 555 is configured as a low-frequency oscillator, tunable over the frequency range of 50 to 60 Hz by Frequency potentiometer R4.\nThe 555 feeds its output (amplified by Q1 and Q2) to the input of transformer T1, a reverse-connected filament transformer with the necessary step-up turns ratio. Capacitor C4 and coil L1 filter the input to T1, assuring that it is effectively a sine wave. Adjust the value of T1 to your voltage.\n\nThe output (in watts) is up to you by selecting different components."
"This is something i've been working on for a couple days and finally got something worth showing. After a while using Radio Frequency Links in some projects i realized that many messages are lost and it requires you to send them over and over again until it reaches the destiny and does what it is supposed to do. I then decided to do something about it and since i know i'm going to lose a few messages in the air at least send it again in a transparent way so it doesn't bother me. In a few words this is an implementation of a protocol that guarantees that a message sent over a RF Link will get to its destiny no matter what. This implementation is based on RF Links, Arduino e Java. At the end of the explanation of the protocol there's an example of where it can be usefull, so, let's get it started."
Collection of information about TEA lasers, CRT's, and a bunch of other things.
Blog post talking about using the Wii Nunchuck with an Arduino, the code could easily be ported to other platforms and the information presented is easy to understand.

WinLIRC allows you to transmit and receive standard infrared remote control signals. This allows you to control your computer using almost any standard infrared remote control. It also allows your computer to control other equipment which uses these signals (stereo equipment).
The Teensy is a complete USB-based microcontoller development system, in a very small footprint! All programming is done via the USB port. No special programmer is needed, only a standard "Mini-B" USB cable and a PC or Macintosh with a USB port.
This simple adapter can be used to convert Y/C video (S-video) to a composite video. This adapter is useful in cases where your video output device has only S-video output but your signal source accepts only composite video input. This circuit works with both PAL and NTSC video standards.
This submini USB scope is based on a Atmel Tiny45 cpu and cost less than 5€ with a homemade pcb
This platform enables you to code a color, high resolution, smooth video game, like Super Mario Bros or Commander Keen on a mega AVR. All video processing is done by software in background using interrupts, with no external active components. You only nee
If you've built a bench power supply using an old ATX computer power supply, you may feel limited by the choice of voltages + 3.3V, + 5V, and +/- 12V DC. Suppose you're breadboarding a circuit that's meant to be run off a 9V battery? This is how to build
Computer power supplies cost around US$30,but lab power supplies can run you $100 or more! By converting the cheap (free) ATX power supplies that can be found in any discarded computer, you can get a phenomenal lab power supply with huge current outputs,
This is a simple section, mainly aimed at novice machine builders such as Robot Wars beginners, but it should also be useful to others. A machine, for the purpose of this discussion is a mechanism of some sort, controlled by maybe a mixture of electronic
Have you ever wanted to run a TV, stereo or other appliance while on the road or camping? Well, this inverter should solve that problem. It takes 12 VDC and steps it up to 120 VAC. The wattage depends on which tansistors you use for Q1 and Q2, as well as
