Build your own magnetic tape data recorder

In what can only be described as either a trip down memory lane or electronics masochism, Michael Kohn has designed and published details on how to create your own data recorder/playback device using some custom circuitry and an audio Compact Cassette deck for the tape hardware. Mike created his own protocol which is based on the length of 10 kHz tones, with the length determining the bit type.

Michael has published the design, circuit schematic and code for the ATTiny2313 microcontroller that is behind this project, so visit here for the details. And for more news, updates and items of interest.please follow us on twitter, Facebook and Google+.

If analogue electronics is new to you, or you're interesting in brushing up your knowledge in order to be able to design your own hybrid analogue/digital creations like Michael - get yourself a copy of "Electrical Engineering 101" by Darren Ashby.

Over 320 pages there is everything you should have learned in school, but probably didn't! This book is great for electronics newbies, or if you just need a refresher course. Topics ranging from Ohm's law to proper usage of an oscilloscope to managing and interacting with employees are covered. The book approaches all of its topics in a very straight-forward, practical manner, and all the important information is summed up nicely in a "Rules-of-Thumb" section. The information presented in this book will provide a great start towards building or reinforcing your EE knowledge. So order a copy today!
