Can a digital capacitance meter measure the capacitance of an inductor?

How to measure capacitance?

How do I measure the capacitance of something, I looked at the local ACE and none of the meters have a farad reading or anything else similar to capacitance.  We have an analog one, and I was wondering if there is a way to use it I just don't know of.

Junk-box Testing Equipment

As inductance and capacitance testing is a frequent topic on instructables, N5ESE's GIZMOs page has several home-brew testing gadgets and misc. gizmos, including:-- inductance meter-- capacitance meter-- frequency generator-- crystal checker-- dummy loads and attenuators-- 'scope probesCool stuff...

Which Capacitance Meter Should I Buy?

I'm interested in testing some electrolytic capacitors I have, as well as some unmarked ceramic disc capacitors.  Which one of these would work best for me? Would this hvac one work? http://www.amazon.com/Elenco-CM1555-Digital-Capacitance-Meter/dp/B0002HDTDQ/ref=sr_1_1?ie=UTF8&qid;=1365901716&sr;=8-1&keywords;=capacitance+meter http://www.amazon.com/Capacitor-Capacitance-Meter-Tester-20mf--200pf/dp/B007MHBCFG/ref=sr_1_3?ie=UTF8&qid;=1365901716&sr;=8-3&keywords;=capacitance+meter Thanks!

How to program ATMEL AT89S52 chip?

Hello. I'm new in forum. I buy a DIY Kit Secohmmeter Capacitance Meter Inductance Meter Frequency Meter, but the chip have no code. The vendor send me a link to download the schematic and the code in C and inn hexadecimal. But I don't know how to code the chip, the board have UAB_ASP connection. If anyone already use that kit and know how to code that, can explain how to code the chip? I attach foto and the code.  Thank's Miguel Rodrigues

9kV 50mA tesla coil NST question. Why does the circuit breaker in my home trip when i plug in my NST?

Please someone help, this is my first tesla coil project, my setup: 230VAC 50Hz input ricci 9000v 50ma NST with a built in GFI (ground fault interrupter) but i bypassed the gfi succesfully .see pics safety gap  7,5 cm diameter pvc secondary 1000 turns #24 magnetwire (0,5mm) secondary 10 turns 8mm copper pipe primary (tapped at 7 turns) saltwater capacitor 16 green beer bottles in a bucket with a capacitance of 0,0122 uF or 12,2 nF (thegeekgroup bucket cap) static spark gap 28mm diameter stainless steel spheres as electrodes with oven fan (temporary, i am building a hyperbaric gap) 10cmx27,5cm aluminum toroid topload with a brass screw as breakout point RF ground aluminum rod 1,2 meter  When i tested the coil for the first time the spark gap was set on 6mm and i got 20cm or 8inch streamers without breakout point but the gfi on my nst tripped after a few seconds. i didn't know there was a built in gfi on my nst so i fooled around with my spark gap and safety gap and the tapping point on the primary hoping to get better performance. after a few runs the gfi started to trip very fast and i could only run the coil with the spark gap set on max 2mm, any bigger then that would trip the gfi on the nst. so i found out that it had a gfi and i bypassed it with thick wire. Then when i ran the nst i got the exact same thing but with my circuit breaker in my home. i have made a video on youtube that shows the problem here is the link: (please help) http://www.youtube.com/watch?v=piH44ohowyE please anyone help me! Any help or suggestion is very welkom!
