Need Someone to Build This

Recommended Posts


I need someone who can build exact assembled kit from http://www.electronics-lab.com/projects/pc/023/index.html

But :
- Infrared diode replaced with EPD-525-0-1.4
- Infrared LED is empty, just give me 2 solder hole for that.

Shipping to Indonesia via EMS (Air Parcel Post).
Will pay using paypal or western union.
Payment made when I get photo of the assembled kit and shipping tracking number.
Please, mentioned your price.

I can't find matched component here :(

Does this project work?
The IR diodes are forward biased which causes the connected gates to always have a high input level.
iR diodes should be reversed biased to generate leakage current or should have no bias to generate a small voltage.

Where can you get 200MHz and 400MHz crystals? The max crystal frequency is about 60mHz. Special overtone oscillators can multiply the frequency, but this circuit doesn't use them.

The schematic shows 74ASxx ICs but the text says that 74H series must be used.
