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.
Heathkits - Learning with Practical Electronics
THD Improvement kit for IG-18 series audio generators
"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.

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.

Linear Regulated Dual Polarity Power Supply
"This document describes how to construct a dual polarity linear power supply which can be configured for any positive or negative voltage between 1.2-35V. A power supply is the fundamental building block of all but the simplest of electronic devices. It converts the alternating current (AC) from our wall outlets into direct current (DC) at some specified voltage. Because so many electronic devices need DC to function properly, a versatile power supply is the perfect addition to a hobbyist's collection of test equipment. " from Wayback Machine
Linear Regulated Dual Polarity Power Supply
"There are two versions of the power supply which are fundamentally very similar. The first is a compact fixed-voltage supply measuring 2.9" x 2.2", which is well suited for applications requiring small size and modest current capacity like TTL logic circuits or op-amp based projects such as active crossover networks. The second is a larger (4.6" x 2.25") variable supply sporting more robust heatsinking, and the regulators are positioned such that they may be mounted to a large chassis heatsink for even greater heat dissipation. And since this version of the supply is variable, it is ideal for experimenting. See the photographs near the bottom where I built one into an ATX power supply chassis."

Wide Skill Spectrum by Building a Robot
These valuable learning materials are partly derived from Robot Builder's Guide of Fred Martin, the course notes at the Massachusetts Institute of Technology.
Wide Skill Spectrum by Building a Robot
Basic Mechanics— Describes basic mechanics, friction, and the simple machines that comprise the building blocks of more complex machines, like robots.
Sensor Design - Without sensors, a robot is just a machine. Robots need sensors to deduce what is happening in their world and to be able to react to changing situations. This chapter introduces a variety of robotic sensors and explains their electrical use and practical application.
Robot Control - The most common kind of robot failure is not mechanical or electronic failure but rather failure of the software that controls the robot. For example, if a robot were to run into a wall, and its front touch sensor did not trigger, the robot would become stuck (unless the robot is a tank), trying to drive through the wall. This robot is not physically stuck, but it is "mentally stuck"
delabs Notes
When you build a robot, you are dealing with Mechanical, Electrical, Electronic and Computer Technologies with the Interfacing.
The improvement in the Wireless Communication, Low Power Hi-Speed Semiconductors coupled with compact gigabytes of Flash/HDD may help build a Creative Robot with a smart brain.

"The electronics industry uses several methods for labelling front panels and enclosures, including screen printing, press forming, erosion, lasers etc.. The common factor of these techniques is that they are generally beyond the home constructor. Having these parts specially made commercially can be very expensive, and the only alternative is standardized scales and fonts."

“One test result is worth a thousand expert opinions”. This has been attributed to a range of people, but most authoritatively to Wernher von Braun, the rocket scientist.
A 40 dB RF Attenuator -
"To measure power of a high power transmitter, or to be able to observe the output signal on an oscilloscope or spectrum analyzer, it is necessary that the signal is attenuated in accordance with the instrument, while it must be ensured that the transmitter is "seeing" the correct impedance. So it requires an attenuator that works with three ports (input, output, and output attenuated), all while maintaining the correct impedance of 50 ohms.
The circuit assembly and is shown here in EMRFD and also in the QST. When properly calibrated can be used for precision measurements in section 0-500 MHz, or a a calibration capacitor C1, can be used for the range of 0-50 MHz with reliability."

Step Down Capacitor - No Heat
Sometime in the eighties, I had to change a blind timer design due to non-availability of a component. A high resistance relay 600 ohm coil was not in supply, 150E was available. The Power to timer was derived from a resistor, I put a 0.47uF 630V and it Worked !. This design of mine, deriving a low voltage from a capacitor shown on right adaptation became popular. I used a 0.47uF 440V AC or 630V DC Plastic Capacitor.
This circuit has been drawn from my memory and i have not tried it out again, just see if it is ok and then try. You should use the fuse of 100mA a slow blow if you want but it is very important. This circuit has to be enclosed in a plastic sealed enclosure to avoid contact.

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.
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.

GainClone Chipamp Audio Amplifier
Gainclone or chipamp is a type of audio amplifier made by do-it-yourselfers, or individuals interested in DIY audio. It is a design based on high-power integrated circuits, particularly the National Semiconductor Overture series.
GainClone Chipamp Audio Amplifier
The Gainclone is probably the most commonly built and well-known amplifier project amongst hobbyists. It is simple to build and involves only a few readily accessible, inexpensive parts. As an amplifier it is highly regarded by many in the DIY community.
GainClone Amplifier Rod Elliott (ESP)
"The amp is based on the Project 19 PCB, so uses a pair of LM3876 (or LM3886) power opamps, run from a ±35V supply. ...........The power supply is conventional in almost all respects. I used a 160VA transformer, a 400V 35A bridge rectifier, and a total of 20,000uF per supply rail - 4 x 10,000uF caps in all."

Recording Technology History
1877 - Edison made the first recording of a human voice ("Mary had a little lamb") on the first tinfoil cylinder phonograph Dec. 6 (the word "Halloo" may have been recorded in July on an early paper model derived from his 1876 telegraph repeater) and filed for an American patent
Dec. 24. John Kruesi built this first practical machine Dec. 1-6 from a sketch given to him by Edison that was made Nov. 29 (not on "Aug. 12" that Edison mistakenly wrote on another sketch in 1917).
Recording Technology History - https://www.aes.org/aeshc/
When Kruesi heard Edison's first words Dec. 6, he exclaimed "Gott in Himmel!" (but these words for "God in Heaven" were not recorded and thus have been forgotten). Others before Edison had tried to record sound, but Edison and his tinfoil phonograph were the first to succeed.
History of sound recording
The phonograph expanded on the principles of the phonautograph. Perfected by Thomas Edison in 1878, the phonograph was a device with a cylinder covered with an impressionable material such as tin foil, lead, or wax on which a stylus etched grooves.

DIY Radio Control Electronic Projects
This project, called "Simple-Timer" is a programmable Timer and electronic switch with an integrated LiPo Battery Monitor that is based around a PIC microcontroller.
The "Simple-Timer" includes a fairly accurate timer that is programmable (via pushbutton) by the user and can be programmed to time a 5, 10, 15, 20,25 or 30 minute event. When the timer/switch is enabled (tap small pushbutton), the onboard LED indicates the output is active by lighting solid (the circuit also outputs the same voltage as your supply/battery voltage using a PN2222 NPN transistor or a high current MOSFET).

Arduino and Freeduino Knowledge
Things are easier than before, there is so much more you can do with this. Starting with a Embedded Project with Arduino type of uC is easy. A PC USB inteface for testing your code. Analog Interface is good for trying out Measurement or Robotic Projects.
Freeduino began as a collaborative project to publish open-source Arduino-compatible production files. The files that resulted from this project allow users to create boards that are 100% functionally, electrically and physically compatible with Arduino hardware. Over time, Freeduino has come to mean hardware that is "Arduino-compatible".
Arduino and Freeduino Knowledge
Freeduino is a free-form version of the Arduino, in that is not developed under a centralized design process.There is no Freeduino team, or anyone to ask permission of: anyone, anywhere, can design and produce a Freeduino product, no questions asked, no royalties paid.

"In order to give support to many electronic enthusiasts who want to build projects but do not have enough money, PCBWay is the first manufacturer who gives them at a low price."
Six reasons why PCBWay is the best PCB manufacturer
Considering a large proportion of electronics enthusiasts are students or beginners, PCBWay has created dedicated channels for sponsorship to encourage these electronics enthusiasts to create their own projects. PCBWay has sponsored more than 1000 projects so far which include robots, rockets, racing cars and so on. PCBWay has also sponsored Makerfaire, SHA2017 and other activities.

Fritzing is Product Design or EDA in Simplicity
"Fritzing is an EDA - Electronic Design Automation software with a low entry barrier, suited for the needs of designers and artists. It uses the metaphor of the breadboard.."
Fritzing is Product Design or EDA in Simplicity
"in the spirit of Processing and Arduino, developing a tool that allows users to document their Arduino and other electronic-based prototypes, and to create a PCB layout for manufacturing."
Fritzing Starter Kit to start learning Arduino
What do you get? The ultimate beginners book teaches you everything you need to know through a series of practical--yet playful--exercises. And that playfulness is the key! There is a paper robot who can turn his head; a fortune teller who is (of course) never wrong (no guarantee on that); a dinosaur who relays the news on your Twitter stream and a pong game on a big LED matrix display.
Fritzing's goal is to provide easy tools for documenting and sharing physical computing projects, producing layouts for Printed Circuit Boards (PCB) and teaching electronics.

Museum Of Electricity - Charles Brush
Yes, there were electric lights powered by central stations before Edison's! Carbon arc lamps saw extensive use throughout the USA and the world from the late 1870s on. - Charles Brush
Museum Of Electricity - Charles Brush
The General Electric Company was formed in 1892. It was the result of a meger between the Edison General electric Company and the Thomson-Houston Company, which themselves incorporated several other companies.
Electricity, technology, and lots of arcs and sparks!
Museum Of Electricity contains Vintage Electrical and Historical images and description. They include the Edison Lamp, Tesla Coils, Lightning and Atmospheric Electricity and the .....
Amazing Jacob's Ladder
So how do they work? First two conductive metal rods are positioned in a rough “V” shape with a slight space between them at the base. A sufficient voltage differential is provided from a high voltage transformer to breakdown the air in the gap between the rods.

Single Digit Voltmeter with LM311
I wanted to design a logic probe as a tutorial, but there were many good ones in the web so i have tried to design a single digit voltmeter. This circuit is a design, i am unable to test it now, later if i test it and find mistakes i will update this page. You can help me by pointing out the errors.
First bear it in mind that it is a single digit voltmeter which is 0-9 counts only on the positive side, that is it can measure +0 to +9V DC +/- 1V error. That may not be practical for the cost of the components above. It may be used as a toy logic probe. The reason for the circuit is not for usage, but to give design ideas. The methodology used is Gut Feel - Thumb Rule method.

Strippenstrolch - Elektronikbasteln
"Strippenstrolch" is thus a pitch name for "electricians". here you can also see a innovative project that combines rainwater harvesting and a solar energy operated pump to flush toilets.
Strippenstrolch - Elektronikbasteln
LED Lighting Projects, Learn Electronics, Basic Circuits and how they work. All in German.
"In Germany one finds this designation now and then for an electrician on the work. Particularly in the winter, if it is still dark in the morning, one often sees "Strippenstrolche" with its building lamp on the building site:"
Combination of Rain and Sun Harvesting
"The inspiration for a self-sufficient toilet flush was now close at hand: I thought at first to work with a power supply that provides me the 12V to the pump. But as a power supply would idle constantly consume energy, I rejected this solution. I have long experimented with solar power, so I decided, now a solar system for our toilets to build. On the flat roof of our garage I installed two 12V - 55Wp - solar - modules (Conrad Electronics). This I switched in parallel."
"As a solar storage currently serves an ordinary car battery 45Ah (later 3 pieces with a total of 135 Ah). The charging control acquires an 8A charge controller (Conrad). So all very simple."
