[QUOTE=yngndrw;241994]Hi,
I have recently found this:
Very Accurate LC Meter based on PIC16F84A
Which got me thinking, how would I go about building an auto-ranging LCR meter ?
I was thinking something along the lines of having a set of Reed Relays which would select between the L, C (Both like in the link) and R (A potential divider) sections and also the different ranges. The problem is auto-selecting between which mode.
Any ideas ? Is it worth just buying something like this instead:
PEAK|LCR 40|METER LCR | CPC
---
I recently got this LCR Very cheap and very good @ LCR Meter ?(LCR METER)?

I make all my projects with SMDs. I use 0805 size exclusively. Never tweezers! They snap! and where did it go? I use flux and an Xacto knife to delicately place the component. then carry a little solder on the iron, deftly hold the part down with the knife and hit with the iron. Seems to work for me. Clean knife often with alcohol. Headband magnifier - Yeah!
PC boards are reasonable. I use ExpressPCB. Software is free, works great. and you get three boards for $61. I put several projects on one board, so i get several projects out of one purchase.
