Here are some Metal Detector Projects that are quite interesting for the purpose of education and experiments in the Art of electronics. This site may be as old as Y2K, but the url / domain may have changed.
Metal Detector Projects
If you are interested in the theory behind the mag I can highly recommend the book The Magnetics Measurement Handbook by J.M. Janicke. Besides a good coverage of magnetics theory, it contains much of what you need to build a useful fluxgate Magnetometer, plus other devices.
Traditional Geophysical instruments include ground-penetrating radar, earth resistivity meter, infrared, and sonar, to name a few. Currently, earth resistivity projects are the most practical for the do-it-yourselfer, although some people have been tinkering with side scan sonar.
Detection of Gold
Just the Jeohunter really works and directly detects Gold – see below screen. And even gold-worth 9-15cm diameter cannon-balls get detected as “Gold” (golden ring & cannonball analyses has identical values), but thats because of the huge metal mass and special shape – alot MDs have “problems” in such situation and perhaps only a magnetometer really works here. btw. there is no difference if you search with Ground Balance minus 200, zero or plus 200, the gold detection always remains the same.
There are historical records of DIY Enthusiasts having created what is known as the “Donkey Kong Gold Hunter”. This Gold Detector uses a Nintendo Unit after many Mods.
Unprecedented Innovations from a young group of Scientists who may change the way we interface with the Electronic Environment around us.
EMS Laboratories – Hobby Electronics
Meggy Jr RGB is designed to be programmed through the popular Arduino software environment, when you hook it up to your computer with an FTDI USB-TTL cable
Meggy Jr RGB is a new kit that we designed as a platform to develop handheld pixel games. It’s based around a fully addressable 8×8 RGB LED matrix display, and features six big fat buttons for comfy game play.
A unique feature of Meggy Jr RGB is that it is designed to be mounted inside a “handle set” — a wooden or plastic case that’s safer and more pleasant to hold than a bare circuit board.
They specialise in online mail order electronics for industrial, educational and domestic applications. The company’s founder started selling electronic kits back in 1993 .

For the advanced Hobbyist there are projects on Microcontroller and Measuring and control devices with the USB and PC Interfacing,
SDR Radio with USB
Electronics experiments for children – “For children it is easier than for adults. Since it is enough, if someone applied sufficient time and a little tinkering with them. Often all it takes is a little push to arouse interest and skills.”
Adafruit Industries is a small company that sells kits and parts for original, open source hardware electronics projects featured on ladyada as well as other cool open source tronix that I think are interesting and well-made.
Adafruit Industries – Unique DIY electronics
All the projects are redesigned specifically to make it easy for beginners to make: nicely silkscreened circuit boards, through-hole parts whenever possible, extra large solder pads, etc. For some kits, you can purchase just the circuit board. To save paper, the easy-to-follow-with-lotsa-pictures instructions are all available online, at ladyada.net-make.”
Atmega328 chip has twice as much storage, runs at 16.00 MHz, just like the latest Arduino. Upload baud rate is 57600, use Arduino IDE v13+. Chip comes preprogrammed with my “no-wait” Arduino bootloader.
- Designed to plug into a breadboard for easy prototyping
- Petite size, only 3″ x 0.8″ (75mm x 20mm)
- All ‘standard’ pins are brought out – Digital 0 thru 13, Analog 0 thru 5, ARef, 5V, Ground, Vin and Reset
- Chip comes preprogrammed with a “no-wait” Arduino bootloader
- 2 LEDs, green power and red “pin 13” just like the Arduino Diecimila
- Available as a low cost kit with standard parts, so its never out of stock
- All through-hole parts are easy to solder
Boarduino (Arduino Clone) Kit
This clone acts just like an Arduino, and works with the latest Arduino software. For many projects it can even be preferable! The kit includes all parts necessary, the assembly is straightforward and well documented.
