    I was recently inspired by the Arduboy - an Arduino business card that plays Tetris: http://www.bateske.com/arduboy/ I would like to create something similar: Instead of controller buttons and Tetris, I would like it to have 2 biometric leads (1 for each finger) and the ability to measure and display the user's Galvanic Skin Response (GSR). Galvanic skin response readings are simply the measurement of electrical resistance through the body. Two leads are touch to two fingertips ...

    1. Create a simple sketch for an Arduino Uno that reads this rotary encoder https://www.sparkfun.com/products/10982 (here is the breakout board I am using too https://www.sparkfun.com/products/11722 ) on an interrupt basis and increase a numeric variable by 1 per detent up if turned one way and down if turned the other way. Print that variable out to my serial monitor on my pc. 2. Create a simple wiring diagram for me to ...

    Need to develop a simple circuit which can store a 10 Digit Number like "98-11-28-79-81" in a permanent memory (ROM or FLASH) On pressing of a button, the 10 Digit number read from the memory and is converted to Binary and Frequency Shift Keying (FSK) is applied to generate an audio message. The base frequency being used for the FSK - is around 22 KHZ. This audio is played out aloud through a Ultrasonic Transmitter. The audio will have a preamble ...

    ASIC Chip and PCB Design for Scrypt Cryptocurrency Mining. We are looking for the most efficient hash rate per watt usage. Our goal for this ASIC chip is 100,000 Hashes/Watt. We are looking for a prototype design and then we will consider mass production options once the prototype is finished. If cost effective we will purchase the NC machines (picking and placing, etc..) to manufacture the boards for this. If not cost effective we will be outsourcing the ...

    I have a few projects I am working on. The easiest will be a simple electronic device I already have the schematic for but I need to add in a microswitch and then I need to put that into a gerber eagle file for pcb production. I then have a few more simple projects such as a schematic which will also need to be done in gerber file for some simple leds such as a few differnt scheamatics for single ...
