Copper Clad Glass Epoxy Wall Panels

We can by Photo-lithography, Laser, Milling, Etching make Intricate Designs on a Single Side Copper Clad Glass Epoxy Board. After that we Multi-Mask the copper side with Translucent Synthetic Lacquer of different shades. Prepare the wall with an epoxy coating and Stick 1 Square Feet panels with tiny rivets or screws. Larger that 1 square feet may cause warp stress, need big screws.

Electrical Diagrams - Control Panels, Reference Tables.

You can also do something that is Geeen. Buy up Surplus Electronics PCBs Old and New with or without Components. After epoxy coating the walls, Fix a thin waterproof hardboard on the wall. Then screw these PCBs as Wall panels, after you have washed, dried and lacquered them.

LED Christmas tree - Learning Electronics

Letter from Chris of PyroElectro.com in 2013 - Happy Holidays!

Here's a project I know your readers will love! It's an all-digital-hardware LED Christmas tree we're calling the Christmas Tree O'Digital Logic.

The tree itself is composed of 64 LEDs built into a spiral sitting on a piece of protoboard. Underneath, the controller uses shift registers and a 555 timer to create two modes of display: a predictable pattern and a random pattern. This should light up any desk or shelf and bring merriment to your readers!

We're also running a Kickstarter campaign to fund our second free online electronics course, "An Introduction To Digital Electronics." We have just 4 days left to raise $2,124. If you would be so kind as to spread the word about our efforts, we'd be extremely grateful!

To build the tree, we'll use 63 green LEDs and 1 red LED. Lots of wire will be needed to make the spiral + cone shape of LEDs from top to bottom. To build a random pulse generator, we'll use some digital logic trickery with a 7404 hex inverter. A 555 timer will be used to drive 8 shift registers, which will control all 64 of the LEDs. Finally, a 4 bit timer should be thrown into the circuit in case we want to slow things down with a divider.

Build Holiday Electronics Projects

micro-readerboard Christmas tree ornament displays a short message, one letter at a time, on a bright single-character alphanumeric LED display. In the animation here, the ornament is displaying the word ornament."

Each ornament is pre-programmed with a list of 36 different short phrases. Every time that an ornament is switched off and back on, it picks a new message from its memory to repeat.

Holiday Projects -

Holiday (Fun Circuits)
25 Light Sequencer using Xmas Lamps - drive 25 small Xmas lights. The lights operate at about 200mA and 3 volts, Anti-Flicker Circuit for LED Christmas Lights. Bells ring Generator -  Three circuit options; Can be synchronized to Christmas tree flashing lights.

Christmas related Circuits - Christmas Flashing-LEDs Badge -  Two-LEDs follow the rhythm of music or speech. Suitable for pins, badges, Christmas decorations. Programmable LED Flashers LED goes to steady state after a preset number of flashes Two simple, wide supply range operating circuits

Christmas Decoration Project
This project flashes 18 LEDs at three different rates and you can use these to create an eye-catching Christmas Decoration. The circuit is kept simple (and low cost) by using the 4060B IC which is a counter and oscillator (clock) in one package.

Ready Kits -

ApogeeKits flashing Christmas tree

Christmas Season Electronic Animated Display Kits
ApogeeKits flashing Christmas tree electronic kit makes a beautiful lighted holiday display. 12 multi-colored LEDs flash randomly. May be powered by a 9 volt battery or a DC power adapter for long term continuous use. User assembly of components and soldering is required.

Grantronics Christmas Tree
"Last November, we published the very popular Christmas Star. This year, our "just for fun" project is in the shape of a tree but we have gone one step further by using bi-coloured LEDs. There are many different light patterns and each LED can produce 16 different colours." -

HowTo: How to build a triac switching unit SSR

"Here's how the circuit works: The optoisolator protects your computer from the evil nastiness of the power line. It has an LED that is optically coupled to a triac inside the package. In our application we are supplying the LED side of the MOC3010 with +5 volts."

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! 

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
