PIC16C63 Midi controlled Light dimmer

This is Ver2.0 of a finished project. I usually do projects about the same way every time. Product definition (10 min), Code outline (10 min), Schematic generation, Build prototype, Write code all at one sitting (This one took about 6 hours), Take a copy of the above file, and delete all but a small section. Debug the section, and put it back into the original file. Repeat with other chunks of code until do ...

Peltier-Powered Drink Cooler!

desktop-sized can cooler From the "Something that Should be Made Department" comes this drink cooler. Ever since seeing peltier devices for sale I have wanted to put one to a cool use, and this is it. :-) The heart of the device is of course the peltier module. photo is from ebay auction for my peltier) I got the peltier I used (pictured above) off of ebay for about $20 after shipping and such. It was in ne ...

Bicycle Persistence of Vision Light Display — February 2007

In February of 2007 I spent a little while prototyping a board that turns any bicycle wheel into a moving display billboard using a single string of LEDs. The idea was to do something that would be very visible, turn itself on and off automatically, have enough processing power to dynamically generate bike computer style displays, and have enough memory to store full resolution bitmaps. The first revision w ...

IR(infrared) Remote Control Relay Board with PIC 12F675 Microcontroller

Introduction  This little project will demonstrate how you can use your old NEC IR protocol based TV,DVD or VCR remote control to control you home appliances like fan bulb or virtually anything. Consumer IR protocols There are a number of consumer Infrared protocols out there and they have been used for every single purpose possible i guess, like PDA laptops and other consumer appliances. RC-5 & RC-6 by ...

DCF77 clock-thermostat using PIC16F648A

Always at the right time your house on temperature This project make use of a PIC16F648(A) and a DCF77 receiver from Conrad (Orderno. 64 11 38) With DCF77 runs the clock from the thermostat always on the right time. Synchronizing isn't necessary anymore. The temperaturesensor is a DS1820 or DS18B20 and on a HD44780 (or compatible) 2x16 LC-Display becomes day, date, time, temperature (with 0.1°C precision) a ...

A remote controlled power RGB LED mood light using PIC16F627A

A remote controlled power RGB LED mood light. Control the colour of a powerful LED light beam with a remote control, store the colours and recall them at will. With this thing I can control the colour of a bright light into many different colours using the three fundamentals colours : red green and blue. Adding them toghether with different intensity can yeld very great a range of colours from the visible s ...

Water Filter Controller

As a fan of taking my dihydrogen monoxide in straight, uncut, uncorrupted liquid form, I purchased a six stage reverse osmosis filter some years ago. My filter is a few years old now, and the super calcium enriched water we have in Michigan has taken its toll. The filter used to shut off when the production tank was full. However, the filter has recently developed a leak in the auto shutoff valve, so it’s c ...

MintLite Part I

MintLite – The Luxeon Powered Mint Tin Flashlight! This idea has been rattling around in my head for more than a month now, and I finally have thought it out enough to do some doodling in Eagle. The basic idea is built around a six watt Luxeon K2. I plan to use a pair of 2.5aH lithium batteries to provide approximately eighteen watt-hours of power. The Luxeon will be controlled by a microcontroller, providi ...

Teddy nightlight multicolor using PIC16F84A microcontroller

Teddy nightlight multicolor A nice night light multicolor, ideal for baby's room. For the realization I used: - Out of a pack of bubble bath for children in the shape of teddy bear - a nightlight with positive economic pressure - Complete circuit with a PIC16F84A (I was at home, but you can use any programmable microcontroller) - LED multicolor I started preparing the teddy bear, all the markings on the pac ...
