	Traffic lights, 2,3,& 4 way, this has the English sequence.
	Simple stepping motor control driver.
	This porch light control has a delay so if lights from a car goes by the porch light will remain on, the delay is about 30 secs.
	This is a power amp that I constructed to use on the Amiga as some monitors do not have a built in amp. build two for stereo.
	This is a pre-amp from the CD output to the Amiga motherboard so you can match the output to the Amiga output.
	This little flasher circuit was made for a Christmas card, on the card was a picture of a Christmas tree, just cut the small holes out where you want to put the LEDs and you have a flashing tree card.
	This clever little circuit was made for a clock, if the power failed the battery would take over. There is also a low battery indicator.
	This cystall oscillator cicuit was made for a digital clock, to replace the 32kHz oscillator to make the clock keep better time.
	This is a simple power supply that was made for a CD player the output is adjustable so that it could be used for other devices that use other voltages.
	This circuit was made to have a number of inputs to a PC, but of coarse it can be used for any mixing needs.Two of these for stereo of coarse.
	This was made for the mic input of the computer, it gives a constant output level. ideal for the voice recognition in vista. You can run on 5 or 12 volt. the circuit draws about 8mA, so you could use a 9v batt instead of 12v.
	This circuit was so I could plug a turntable into the computer to transfer from my vinyl records to mp3 for playing on a portalble mp3 player.
