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.

Copper Clad Glass Epoxy Wall Panels

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.

Electronic Solar Umbrella

There are places like your Backyard, outdoors, a village... where your Gadgets will stop working !!!

You will feel suffocated when your Smartphone or Tablet fails to respond to your caring strokes. Your Dupey is perishing due to Undernourishment. All you need is "Electronic Solar Umbrella" which was invented by me delabs on June 1st 2014.

Electronic Solar Umbrella

The Red Light is for Data Networking SmartUmbrellas using Advanced Multi-Threaded Infra Red Technology.

SUN - Smart Umbrella Networking

I just invented the SmartUmbrella - My Drone is Rushing to the Patent Office.

(Keep this confidential till my drone returns safely, the beagle boys are using Blimps with Large Magnets to capture Drones.)

Adventures of Earl Muntz and his TV

A History of TV is not Complete till you Learn about the Adventures of Earl Muntz. How he cut cost to Promote his TV Sets by Incremental Pruning of Parts from a Working unit.

Adventures of Earl Muntz and his TV

What is important to learn from it though, is that we should not overdesign or underdesign. We need to design a cost effective product within customer budget. More Bells and Whistles in yet another Model. A Model to cater to every Purse. And a BareBones model for those who just can barely afford it.

History of Muntzing

Muntz Story

"He took a trip to New York City, checked into the Warwick Hotel and ordered three television sets delivered to his room: an RCA, a Philco and a Dumont. He turned all three televisions to the same channel and began pulling tubes from each one by one. When he pulled one tube too many from a set and the picture went black, he would make a note. Then, he put all the tubes back, changed the channel to another of the four television stations operating in New York City and repeated the test."

The Philbrick Archive - Bob Pease and The OpAmp

This site is a free non-profit repository of materials from GAP/R George A Philbrick Researches, the company that launched the commercial use of the Operational Amplifier in 1952.

The Philbrick Archive and Operational Amplifier

The Philbrick Archive - Bob Pease and The OpAmp

The first commercial Operational amplifier was the K2-W op-amp. It was based on the amplifier used in the Philbrick modular Analog-Computor "black boxes ".

First Opamp K2-W op-amp

That amplifier's basic circuit architecture, in turn, was probably inspired by an earlier amplifier designed by Loebe Julie (Dan Sheingold and Bob Pease, thanks for helping me with this information). The K2-W Operational Amplifier entered the commercial market in 1952.

Mouser Electronics - Electronic Components

Mouser Electronics, Inc. is an electronic component distributor, focused on the rapid introduction of new products and technologies to electronic design engineers. Mouser.com features over 850,000 products online from more than 330 manufacturers.

Mouser Electronics - Electronic Components

You can procure components like Optoelectronics, LED Lighting, Semiconductors, Discrete Semiconductors and ICs. They also offer Development Tools useful for the R&D Lab. You can even get Test & Measurement Instruments and also Some Tools for Electronics Manufacturing.

Designing a Tricorder BoosterPack

"The combination of affordable electronics design tools (e.g. Mouser's MultiSIM Blue), open source software licensing, desktop manufacturing equipment (e.g. 3D printers and CNC machines, and PCB manufacturing services (e.g. PCB Assembly Express) that cater to small volume productions are making the niche product design affordable and easier than ever before."

Analyzing the Possibilities: Designing a Tricorder BoosterPack

In the world of Star Trek, Captain Kirk and crew have access to an incredible assortment of 23rd century technology to help them on their missions. The Communicator, the Phaser, and of course, the Tricorder. For the uninitiated, the Tricorder is jack-of-all-trades device that allows a crew member to scan their surroundings to acquire information on just about every environmental variable possible.

Electronic Hobby Projects - Chemelec

This is one of the oldest Electronics DIY Project Sites in the Internet. I now discovered he has a dedicated domain too. Gary from Canada has many useful schematics and even provides kits and parts.

Electronic Hobby Projects - Chemelec

Some projects that may ring bells in your DIY Brain
  • A 10 Watt RMS Amplifier
  • A Solar or Wind Charger/Dump Circuit
  • A Cat or Dog Detector
  • Inverter, 12 volt unit, Mos-Fet design
  • A 25 LED Chaser". (Sequencer)
  • A Metal Detector, for Pin Pointing.
  • Watt Meter", Measures True RMS Watts
  • Pulse Induction Metal Detector
A Mos-Fet Power Inverter

A Mos-Fet Power Inverter

This circuit will provide a very stable "Square Wave" Output Voltage. Output Frequency is Adjustable and Stable. Can be used to deliver a wide range of output voltages by using appropriate turns ratio. Additional MosFets can be paralleled for higher power.
