Adafruit Industries – Unique DIY electronics

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.”

Boarduino Kit Adafruit

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.

Metal Detector Circuits Problem

With the best wishes for you. I found your address and browsed your website. I have a question and hope to take your help and answer.

I need to good metal detector’s circuit and I find several in the web, any of them worked ? what is a problem in them and where can I find one that works with best depth? Could you design or point the mistake in some circuits? Thank you for your answer beforehand.

Thank you for your answer and sites. But some of them that are professional namely “twin loop” built but it has problem and didn’t work.

I think it may be a indicated, there is a problem with them. How can I make it correctly? could you proper design such circuits?

I am not professional and of you do, I will pay for your works.

If you clearly specify what you want with a drawing, And indicate what you may be able to pay and your contact details too…….

Then, I will publish your request in my site. People visiting my pages may contact you. You can Try it out, I may not be able to help now.

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.
