What is the smallest voltmeter? I'm looking for the very smallest -- panel mount -- LCD voltmeter. My Google searches have been dissapointing. The smallest I could find is about 2" wide. This will be part of a 12V bicycle light system. It will mount in a small box, probably on the handlebars. It's measurement range should be about 8 to... 6 Feb 2007 11:12
FET basics Hi, I'm studying the input stage of the following frequency meter : http://www.madlab.org/kits/FrequencyMeter.pdf http://www.madlab.org/kits/frqmeter.html I'm having a little trouble understanding how the FET works. First, the polarization of the transistor. To operate, Vg must be lower than Vs. Let's say ... 25 Jan 2007 12:56

My sending signal somewhat differs with my receiving signal. I hook up both signals on the oscilloscope and I get this clear but different signal, Here is a picture I posted of the signal... 28 Nov 2006 18:50
Digital automotive tach circuit? Anyone have a simple digital tachometer schematic handy? I want to put a 4 digit LED tach into my van. Resolution of 50rpm is fine. Fed by the TACH output of a six cylinder GMC on distributor coil. If it isn't much more difficult, I'd like to be able to drive a bar graph of 12 to 16 LEDs as well. ... 30 Oct 2006 08:25

Neurophone - Real?? I hope so but am afraid not. Hi: I have read about the neurophone which claims to produce auditory perception through nerve stimulation. Something to do with electric signals of certain frequencies being sensed as sound by the brain. Science proves that temporal bone vibration can be used to cause auditory pseudohallucinations. Check o... 30 Sep 2006 09:44

12VDC to 18.5VDC I have an old laptop (366MHz) which takes in 18.5V @ 3A by external (switching?) power supply. (It didn't have a battery with it when I bought it - got it 2 years ago for about $200.) I recently built an external battery pack, powered by 16 Energizer 1.2V 2500mAh NiMH AA cells, to power my laptop in lieu of the ... 12 Aug 2006 13:31 |
