This guide shows you how to build a Frequency Counter capable of measuring frequencies from 1Hz to over 2MHz using an ATTiny2313 AVR Microcontroller. The PCB also provides access to the unused microcontroller pins, so that the board can also be used as a general purpose AVR development board with an LCD.
This design is available from www.nuxieshop.com as a complete kit, as well as pre-programmed AVRs and blank PCBs.

At long last, I have finished the redesign of my Function Generator.
A kit is available from Sparkfun Electronics, or blank PCB's from www.nuxieshop.com.
Some of the improvements include:
- Onboard power regulation with external wall wart supply
- TTL Square wave buffered output
- Sine/Triangle output centred around 0V with buffered virtual ground (important for audio!)
- Onboard pots for amplitude and frequency adjustment
- Mode switch to switch between High and Low frequency outputs
- Much better signal routing to optimise output signal to noise ratio
- and much more..

At long last, the new XR2206 function generator design is nearing completion. I'm hoping to finish the design and testing this week, and have a batch of boards fabbed and parts ordered next week. Two of the major improvements include various power supply options from unregulated AC input to split or single supply DC. Also, a TTL logic squarewave output. The sin/tri wave output will be fixed to ~1Vp-p, and an extra buffer/amplifier board for adjustable output. And finally, for ease of use I'm finishing the design of a modified frequency counter based on an ATTiny micro outputting to a 16x2 LCD.

Phew!
After a long, busy time away from this site, I have decided to look into selling some of the designs I have made, as well as some others I have had on my mind.
So please help me decide which products you'd most like to see by voting in the below poll, and if you have any other ideas please post them in the comments section or send me an email.
nuxieshop.com is now open! Function Generator kits are available, more to come.
Kits are now sold exclusively through Sparkfun Electronics.

Apologies for the lack of updates over the last month, I have had a lot on and haven't had time to put up some new stuff. But I have been working on an updated function generator, with a few new features and a cleaner design. This design is for a simple crystal oscillator tester. When projects that use crystals don't work, it can be caused by a non working crystal. This circuit will let you check and eliminate dead crystals from your own projects. |

If you have ever seen projects involving LED Matrix displays, wanted to know how they work, or how to use them in your own project then this guide is for you. The construction and operation of the LED matrix display will be explained, as well as various ways to control them. Picture from Sparkfun Electronics |

After aquiring a brand new 20MHz Two Channel Oscilloscope, I felt I needed something to actually use with it.
In this guide I will show you how to build your own Function Generator. Including component selection, designing the circuit, breadboarding, PCB layout, homemade PCB manufacture through to the finished product.

My Hackaday entry is a PIC Microcontroller prototyping board, based on the 28 pin Microchip 18F2x5x USB enabled microcontrollers.
There are three different versions - one through hole DIP and two surface mount SOIC versions.
With the use of the included USB bootloader, the user can easily program the microcontroller in a few seconds via the USB port.
