Hallo,

i like to build electronic things at home for myself...

so i found something in the www i want to build, look at here:

http://www.ncweb.com/biz/dan/index.html , the digital display voltmeter.

Can somebody tell me, where i can find a construction manual or a pcb, electronic plan or something else where i can build myself such a digital display voltmeter???

Thanks a lot
Peter

Unless you are going to get an awful lot of satisfaction out of building it yourself, you would be better off just buying one. You would probably spend a lot more money on parts than it would cost to buy one, or buy a kit. Your main problem will be finding a tiny LCD display like that. I haven't seen any surplus LCD displays anywhere near that small. The single piece prices for commercial LCD displays will quite high. Also, many designs would require a microcontroller, and if you are not set up to program them, that is something else you will have to buy.

PS here is a very small voltmeter(38x14x5.5mm) that would just need a regulator and voltage divider. http://www.marteltesttools.com/products.php?cat=114&action=detail&id=73
