A digital timer for $28!

What's the catch: you have to put it together yourself and
you have to supply a few items you most likely already have.

Timer features:

o 2 digit .57" LED display

o 0.1 to 990 second (16 1/2 minutes) timing range

o Real keyboard switches, unlike the *&#?! switches on some
$200 timers I know of

o 10A relay contacts, rated for 300W incandescent loads.
Arc suppression makes it suitable for use with cold light heads.

o Small size to Free up valuable space on your work area.
The timer can be constructed in two units: a small, light
3x5x1 inch control box and a separate under-counter box
with the relay, power supply and plugs. No more power cords
running around your work area. The index card sized
control box can even be wall mounted with Velcro.

The kit contains all the electronic parts, programmed uP,
instructions and 2x and 1x artwork for the DIY PC crowd.

This kit is designed to answer the question "How economically
can one obtain a digital timer?" To that end, you supply the
following parts that most likely already have in your
junk box (or that you can buy at Radio Shack, if you are junk poor):

o A box
o A wall-wart power supply: 5V DC or anything above 7.5V AC/DC
o A circuit board: 2x4 inch printed circuit or wire-wrapped perf-board
o A duplex power outlet, line cord, on-off switch
o Wire, screws, solder ....

I am doing it this way because I can't see selling you things
that you likely already have.

The electronics kit costs $28 + postage

A printed circuit board with additional connectors, wiring harness
and a machined socket for uP: $12 (+ postage if ordered separately)

Postage in the US is $2.00.

Please email me for more details.

Thank you very much for your time...
