Digital Timer Kit - $28
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, frees up valuable space on the baseboard. The kit contains all the electronic parts: programmed uP, resistors, capacitors, switches, relay. Included are assembly and operation instructions, schematics and 2x and 1x artworks for those who etch their own circuit boards. This timer kit is designed to produce the most bang for the buck. To that end, you supply the following parts that you most likely already have in your junk box (or Radio Shack, if you are junk poor): o A box o A wall-wart power block: 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 .... 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. -- Nicholas O. Lindan, Cleveland, Ohio Consulting Engineer: Electronics; Informatics; Photonics. |
