Heathkit Educational Kits

Heathkit was a well known supplier of electronic kits from 1947 through the early 1990's (although no new kits were developed after 1986). An incredible number of kits were offered including test equipment, amateur and SWL radio, audio, televisions, computers, robotics, automotive and other items difficult to categorize.

THD Improvement kit for IG-18 series audio generators

THD Improvement kit

"The meter buffer is a crucial part of improving the THD specification of the IG-18. The non-linear loading of the analog output can create additional harmonic components due to the non-linearity of the diodes used to drive the meter."

History and Antiquity

In 1947, Heath introduced its first electronic kit, an oscilloscope that sold for US$50 -- the price was unbeatable at the time, and the oscilloscope went on to be a huge seller.

The Heathkit Virtual Museum, a tribute to the Heathkit era-a time when building electronic kits was a favorite pastime for many electronics hobbyists. This commemorative virtual showcase takes you back to the Heathkit age which began in the late 1940's and lasted through the early 1990's.

Then you ought to look around at Bill Wilkinson's Heath Company Page if you want to know more.

Some Entertaining Projects are -

Mr. EQ - A simple, yet potent DIY equalizer. Schematic, PCB/perfboard layouts, and photos.

Little Gem - Two 9v battery-powered amps based on the LM386. Schematic and PCB/perfboard layouts.

Eighteen - The Marshall 18W adapted for use as a distortion stompbox. Schematic, PCB/perfboard layouts, and photos.

Tonemender - An ultra-flexible tonestack with clean boost. Schematic, photo, and PCB/perfboard layouts.

Runoffgroove - DIY Articles and Schematics

Thor - The legendary Marshall 100W Super Lead adapted for use as a distortion stompbox. Schematic and PCB layout.

The Thunderchief project, released in March 2004, was the first runoffgroove.com circuit that was developed using the tubes-to-FETs process. Enlightened and inspired by Doug Hammond's excellent Meteor circuit, we used the same approach in an effort to capture some of the legendary magic of the Marshall Super Lead. The circuit's performance pleased us, but there were issues.

Splitter-Blend - Dual parallel buffered effect loops with blend control. Schematic and perfboard/PCB layouts.

Professor Tweed - The Fender Princeton adapted for use as a distortion stompbox. Schematic, PCB/perfboard layouts, and photos.

SpikenzieLabs - Kits and Projects

It is nice to see many building solutions over the Arduino base like this Prototino. Both hardware and software of Arduino are Extensible. This gives opportunity for New tools and Solutions over this compact system Framework.

One Idea can be an Arduino with a CPLD and Universal I/O driver for robotics. This can come with a Visual IDE which is close or better than the old Visual Basic 6 in usability.

An Youngster can just Drag Drop Components and Link them to build his Robot or Home Automation Solution. Robotics Designers can have the option of looking at the code/hex if needed.

delabs Notes

Prototino an Arduino clone for Prototyping

 The Prototino is an Arduino clone with a built in prototyping area. Designed to make a permanent version of your project once you have perfected it on a breadboard but without the expense of embedding your original Arduino into your project.

The Prototino also makes your project more reliable and robust. With the prototyping area integrated into the board with the microprocessor, your project will have fewer boards and fewer wires, and because of that, fewer mistakes and fewer shorts.
