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.

OpenServo – Digital servo for Robotics

OpenServo is an open community-based project started by Mike Thompson. Low-cost digital servo for robotics being the goal. New code and hardware.

NoccyLabs – Electronics and microcontrollers

A Reference and Dictionary of electronic circuits, microcontrollers and other chips. Basic Theory and Components too.

NoccyLabs – Electronics and microcontrollers

Here you can find some information and experiments on the TI Launchpad – MSP430 series, Atmel AVR/Arduino and Microchip PICkit2 / PIC16F series.

MSP430 LaunchPad and Value Line MCUs provide a complete development environment to enable applications including 3D glasses, gaming controls, touch sensing, smoke/fire detectors, wireless networking and more.

LaunchPad development kit

The LaunchPad development kit is a MSP430 MCU Value Line kit. The open source kit includes all of the hardware and software needed to easily launch designs based on TI’s MSP430 Value Line MCUs, they offer up to 10X performance and 10X battery life over 8-bit MCUs. LaunchPad supports rapid prototyping and development by allowing developers to quickly drop-in MSP430 Value Line MCUs to evaluate, program or debug devices.

CadSoft EAGLE Layout Editor

The EAGLE Layout Editor is an easy to use, yet powerful tool for designing printed circuit boards (PCBs). EAGLE offers the three modules: Schematic-Editor, Layout Editor and Autorouter embedded on one single interface.

CadSoft EAGLE Layout Editor

EAGLE is easy to learn, easy to use and easy to buy. It runs on Linux, Mac and Windows and allows feature enhancement, such as simulation, 3D-visualization, data import and export and self defined commands, through User Language Programs (ULP’s) which are partly integrated in EAGLE

The name EAGLE is an acronym, which stands for .

Easily Applicable Graphical Layout Editor.

The program consists of three main modules, Layout Editor, Schematic Editor and Autorouter. These are embedded in a single user interface. Therefore there is no need for converting netlists between schematics and layouts.
