Day by day, electronic devices are more and more, involved in our lives. Sometimes making things easier, another times creating head aches. For some peoples, "playing" with tiny electronic parts become an opportunity to blend imagination, knowledge, necessity and pleasure... Name of it is "HOBBY", and sometimes, this became more than a game... became a vocation.
Along the time I realized many projects, more or less important... In following pages I will try to describe some of them...
Here
is a collection of circuits, hardware designs, firmware and software that has
been gathered together to assist hobbyists and other developers of
electronic circuits.
Circuits are presented that have an open discrete design i.e. use of discrete
components rather than proprietary integrated circuits. Components should be
easily obtainable or easy to substitute.
My current interests focus on building simple projects around microcontrollers. I use the PIC microcontroller from Microchip Inc

I
have designed these circuits for my own hobby use, and I presented here as
it is. If you don't understand, how the described circuitry works, better
don't use it!. I have tested the circuits presented in this page (all
worked well ), but there is no guarantee that, the circuit
descriptions and diagrams are entirely correct.

Safety First: Please use at all times when dealing with high voltages or circuitry connected to the mains. Please consider your own safety and the safety of others as well consideration for the environment, both physical and electro-magnetic.
EPROM PROGRAMMER |
This device become a necessity in any electronic workshop... So... I built one, WILLEPROM PROGRAMMER following his design.
This was my first try, and it didn't work from the beginning... some errors at schematics made me "blue"... Anyhow I managed it, and after few minor modification, all was O.K.
