Subaru Turbo FCD
Plug-and-Play Fuel Cut Defend (PnP FCD)
For the Turbocharged 1991-1994 Subaru Legacy Sport Sedan
-- And most other vehicles utilizing a separate MAP-based fuel cut
The Plug-and-Play Fuel Cut Defend will eliminate that pesky overboost protection when running more boost than your ECU thinks is safe. On a 1991-1994 Subaru Legacy Sport Sedan, the ECU can sense up to 29 PSIa (absolute pressure, includes atmospheric -- about 14 PSIg at sea level) and will cut the injectors' pulse width if it sees 28 PSIa (about 13 PSIg at sea level) or more for about 3 seconds. This is to protect against the extreme overboost condition where the turbocharger's wastegate actuator sees no pressure and does not open, allowing the turbo to provide as much boost as it is capable of.

OmniSoC
The OmniSoC - A Mixed-Signal Microcontroller Experimentation Kit
Book Written by Chris PaianoThe OmniSoC project/experimentation book introduces the reader to electronics; it contains a lesson on basic electronics, and detailed instructions for assembling the kit of parts. The main part is the mixed-signal (digital and analog) microprocessor / microcontroller - the PSoC. The rest of the parts are support pieces; every function of the OmniSoC is performed inside the chip. The four main functions of the OmniSoC kit are:
Cymon - a touch-switch and LED version of the classic handheld game, Simon(tm)
AudiChron - hear time with this clock for the ears; takes advantage of the human ability to catch rhythm and creates a background sound that anyone can tell the time of day from. Useful for audio recordings.
Magnetometer - A metal detector that works by varying an adjustable tone when metals are near the "coil" of traces around the edges of the board.
Theremin - An eerie musical instrument that is played by moving your finger towards and away from the sensor pad; no physical contact necessary!By reading through the OmniSoC book and building the kit from the assembly instructions, the reader will gain a better understanding of electronics in general, as well as how to build circuitry and how to solder. In addition, there is an introductory lesson on the C programming language included, as that is what the PSoC is programmed with.
If the reader is interested in customizing the OmniSoC program or even creating one from scratch, he or she can purchase an inexpensive PSoC burner here to expand the capabilities of the OmniSoC kit; the microcontroller chip included with the kit may be burned repeatedly for various experiments and projects. With this kit, the reader is constructing an entire PSoC test platform, complete with four touch switches, four different colored LEDs, standard audio output, capacitance sensing, inductance sensing, and precise timekeeping!

Personal Audio FIFO Buffer – A FIFO (First In First Out) buffer can always be filled with the last minute or two of sound without using any storage space, for capture and record on demand. Instantly capture important information even if it has already been said before you decide you want it! At the touch of a button, the last minute or two is recorded immediately – and real-time recording begins right at the end of the buffer until the button is hit again. Perfect for those business meetings (capture any verbal promises with ease!), brainstorming sessions (store those good ideas as they’re identified!), or even capturing select nuggets of important information from class lectures (incredibly efficient note-taking!). This unit will allow connection to a telephone line so you can capture any important calls through your FIFO as well. The myriad of uses is virtually endless!
