Christmas Tree – CircuitStew

The true Christmas Spirit is in giving, You can only give if you have something, right. You can Have when you Acquire Skills, Imagination and a Cheerful Attitude.This will help you Create Things! – dapj

Christmas Tree - CircuitStew

Develop a Skill this Christmas, Build these small LED Trees and give it to people who need a little bit of cheering up.

Christmas Tree – CircuitStew “This was the first and last complete prototype that I made on proto board. This style of prototyping produces circuits that are very difficult to understand, debug, and modify. Because of all the extra work involved they also take forever to assemble. Suddenly I became very interested in designing and fabricating custom pcbs….”

The name CircuitStew refers both to the jumble of electronics presented here and to circuit boards suspended in neon green copper etching solution. – Derek Wolfe

Beetle Robot guided by Light

First have a look at this How to Build a Robot a BeetleBot. This sparked the long lost memory of a book i read around 35 years back. My age was in single digits. This was when i had neither an idea of electronics or could afford any parts.

I had built many physics projects like weighing scale, gramophone, telegraph system, crystal radio. I will try to explain these later. Calling bells, gears and magnets from the flea markets my source of electricity & magnetism.

Beetle Robot guided by Light
I read a hobby book from UK for children. It was a Beetle Car Bot, with four wheels and 4 light sensors. It could be LDR or photo-transistors, i do not remember. The light sensors were at the four corners of the car. The maneuvering was by variation in the speed of each wheel. It was based on germanium transistors mostly.

Four large lamps like 40W, had to be mounted on the ceiling, at the four corners of the room. By turning on and off these lights, this bot could go anywhere in the room. The whole book with pictures was dedicated to one bot and how-to build one.

Now that we have PIC and AVR; we can use Dimmable LED Lightning arrays to guide the bot. The challenge is in the mechanics of the bot, we have to forget that we have wireless for some time. Try this out.

Message: I want to combine Ne555 with 74154 IC.The indication of the outputs must be shown with LED’s but up to so far it need 15 outputs ,is it possible the way i did? if not i will need your assistance

Mail from CY

See these circuits you will get an idea, Using CD4514 is also possible.

Electronic Crafts – HandMade Electronics

“What happens when designers and makers look under the hood of the technologies that surround them and get their hands dirty with hardware and electronics?

This series of objects are the results of research in making our own electronic products while mixing in all sort of other crafts and technologies.”

Before Hams invented DIY Electronics and even before Electric Current gained any respectable position in the Manufacturing Community. The thing that was making many heads nod in unison, was Steam Engines.

Coal, Steel and then Steam Engines made the word Industrial Manufacturing very Meaningful.

Electromagnetism: – An electric motor in 10 minutes

The motor is simply a battery, a magnet, and a small coil of wire you make yourself. There is a secret to making it (which I will of course share with you) which is at the same time clever and delightfully simple.

Other Projects – Fun with High Voltage, A 10 minute railgun, A 30 second motor.

Radio: A quick and simple radio

The reason a crystal radio does not need any batteries is the amazing capabilities of the human ear. The ear is extremely sensitive to very faint sounds. The crystal radio uses only the energy of the radio waves sent by radio transmitters.

Others are Building a radio in 10 minutes, Build a portable crystal radio, A radio out of household items, A simple AM transmitter, The Three-Penny Radio.

Computers and Electronics: A Computer Controlled Transmitter

In this project we will build a very simple radio transmitter that you attach to a serial port on your computer. The computer then runs a free program that converts words you type into radio signals that are decoded by another computer, using a cheap radio receiver, and a sound card.
