AC Light Dimmer - Andrew Jessop March 2006 This project came about because a friend of mine had something similar as a component for his final year electronic engineering project. We decided that we would have a kind of competition to see who could build an AVR based AC light dimmer the quickest. I was interested because I had always wanted to experiment with AC power control, and this was the perfect, simple little project. AC Dimming Theory Explanation to go here. Hardware Software The code for this project was written in BASCOM AVR - a BASIC compiler for the AVR microcontrollers. References Silicon Chip Open Hardware Junkies LPC1343 Reference Design - Vimperator LPC1343 Reference Design An open-source hardware reference design for NXP's USB-enabled, Cortex-M3 LPC1343 The LPC1343 is a low-cost, easy to use Cortex M3 chip with 32KB flash, up to 8KB SRAM, and USB 2.0 HID and Mass Storage support built right into the ROM, saving you flash memory, as well as time and effort compared to implementing a full USB stack yourself in code. Thanks to the built in USB support, these chips also include a new USB bootloader that will cause the chip to enumerate as a mass storage device if P0.3 is set high in ISP mode (see p.251 of the User Manual, v0.07), making updating the device quick and easy. The 1343 is an attractive choice for situations where price is an issue, but USB connectivity and a reasonable amount of processing power are also required (the maximum clock speed, for reference sake, is a respectable 72MHz). Concept We intentionally made the reference board as simple as possible. Hardware: Eagle Schematics and Board Files Schematic Where can I buy one?

Raspberry Pi The Raspberry Pi is a series of credit card-sized single-board computers developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools.[3][4][5] The original Raspberry Pi and Raspberry Pi 2 are manufactured in several board configurations through licensed manufacturing agreements with Newark element14 (Premier Farnell), RS Components and Egoman. These companies sell the Raspberry Pi online.[6] Egoman produces a version for distribution solely in China and Taiwan, which can be distinguished from other Pis by their red colouring and lack of FCC/CE marks. The hardware is the same across all manufacturers. In 2014, the Raspberry Pi Foundation launched the Compute Module, which packages a BCM2835 with 512 MB RAM and an eMMC flash chip into a module for use as a part of embedded systems.[10] Hardware[edit] Processor[edit] Performance of first generation models[edit] Overclocking[edit] RAM[edit] Networking[edit] Peripherals[edit]

MicroFTX The FT230X supports bitbang GPIO (general-purpose input/output) modes that allow you to set and read digital pins directly. It’s a great way to let your computer drive a simple binary output, or to read the state of a switch. For full details, see the FT230X website and datasheet. Two forms of bitbang are supported. BITMODE_BITBANG uses the RX, TX, CTS, and RTS pins and works out of the boxBITMODE_CBUS uses the CBx pins, but needs to be enabled first in the EEPROM On Linux, libftdi provides a pretty easy way to use bitbang. To test it out, download this file as ftdi-bitbang.c, compile, and run it: $ sudo apt-get install libftdi-dev build-essential $ gcc -o ftdi-bitbang ftdi-bitbang.c -lftdi $ .
