Hi,
I have recently found this:
https://electronics-diy.com/lc_meter.php
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:

Also on a different subject - I'm looking for ideas on ways to prototype. I usually use a bread board and then strip board. Attached is a recent project which was done on a strip board which has come out very small and quite cute, but there are probably better methods.
I currently have a 20x4 LCD plugged into my breadboard with a pin header but I'm worried that when I remove it - The holes won't grip wires very well.
In another thread, it was suggested to make PCB's of common circuits and connect them together with wires, saving on re-building the common circuits and also saving breadboard space, but what other methods are there ?
Thanks,
-Andrew.
PS: Yes I have Googled.

Edit: Oh, before I forget - What are the usual wattages for SMD resistors ? In particular 0805 and 1206 ?

Edit2: Okay I know I'm annoying with having 4 questions in a thread, but it saves cluttering the Forum:
Has anybody got one of these:
**broken link removed**
Are there any other sizes of tip that fit it ? Maybe from a different iron that fits anyway ? Suggestions for a decent temp controlled soldering iron with LCD to show temp and different tips ?
Do 24V DC Therm-controlled soldering iron's use the same connectors ?
Would this fit my base station do you think:

It's just that the Weller systems seem good, but are very expensive. I would love that iron even if I had to use my own base.
Thanks.
