Function Generator Kit (http://www.sparkfun.com/commerce/product_info.php?products_id=9002) Frequency Counter Kit (http://www.sparkfun.com/commerce/product_info.php?products_id=9003) Blog - Latest Sat, 03 Jan 2009 20:12:05 +0100 http://www.nuxie1.com/guides/funcount-frequency-counter.html 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 (http://www.nuxieshop.com/) as a complete kit, as well as pre-programmed AVRs and blank PCBs. Guides - Electronics Guides Sun, 21 Sep 2008 01:58:29 +0100 http://www.nuxie1.com/guides/fungen-v2-kit.html At long last, I have finished the redesign of my Function Generator. A kit is available from Sparkfun Electronics (http://www.sparkfun.com/commerce/product_info.php?products_id=9002), or blank PCB's from www.nuxieshop.com (http://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.. Guides - Electronics Guides Sun, 31 Aug 2008 01:01:06 +0100 http://www.nuxie1.com/blog/update.html 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.
