Three new Star Simpson’s Circuit Classics boards have arrived at the Adafruit online electronic store in the form of the Dual-LED Flasher, the Stepped Tone Generator, and the Bargraph Voltage Indicator.
The individual boards are priced at $39 and come complete with circuit schematic and everything you need to carry out experiments and increase your knowledge of electronics.
Adafruit explains more about what you can expect from the Star Simpson’s Circuit Classics which are now available to purchase directly from the Adafruit online store.
Each kit includes:
• Printed Circuit Board (PCB): Includes the circuit itself, the circuit’s schematic, and a description of the circuit, all in Forrest’s iconic hand-drawn style, traced directly from his books. (Prototypes are OSHPark purple, but the final production run will be blue.)
• Through-hole Components: All the components you need to build a working circuit. Easy to place and solder on the PCB thanks to clear footprints and large, friendly solder pads.
• Display Stand: made of high-quality blond ash wood, each stand is crafted to let you proudly display your work.
First we have the Stepped Tone Generator. This circuit gained a life of its own, jumping from the pages of the 555 Timer IC Circuits Engineer’s Mini-Notebook and out into the world as the storied Atari Punk Console.
Next up is the Bargraph Voltage Indicator. With this kit, you can measure batteries or use it to explore and understand other electronic circuits that you find in the world.
Lastly we have the Dual LED Flasher. This circuit is a rewarding first project — with just nine components you can get the satisfying effect of making LEDs light up and blink. The functionality of this kit is charmingly complex despite its simplicity.
