Found another DIY ESR Meter...Anyone seen this one?

[TheLaw]

I'm on an ESR craze. Today, after about an hour of searching, I found this ESR meter, and it seems to be one of the better ones out there. You'll need to make your own PCB but that shouldn't be too terribly hard.

What do you guys think?

I'm in the process of building one since I have most of the parts lying around except for the MCU. I have flashed an attiny before with Ponyprog and its a breeze. For Pic's, this will be my first and wondering is there anything I miss?
The source code is in .hex that I know, what's with the .jal and the JAL compiler? Can someone enlightened me on these?
I'll come to the calibration part later. Thanks

Ya, I'd love to build one of these, and my father said he has a majority of the parts, the hard part would be programming the chips.

I got a programmer that supports around 35000 chips and would love to help, problem is I live in Norway hehe.

Well then we'd have to get you to buy the chips, program them, and do a big batch order.... OR.... You can just move to the US :P

.hex is the file you flash to mcu. .jal is the source code written in JAL language (a bit unusual choice to use that instead of C or asm). http://www.voti.nl/jal/index.html

Maybe I will try to build this myself too or a meter that can read farad as well.
If you need chips programmed I can do it, I think I got soic adapter as well if you choose not to use the dip.

I can move to the US alright, just send me your sisters email and I will take it from there hehe

Post a question.
Here are 2 PIC's with the same marking except for the ending code. Of cause the circuit indicated item 1. What's the difference between these two? Cost wise, the later is 34% cheaper.
1. PIC16F690-I/P
2. PIC16F690-E/P
Thanks

The "I" suffix means Industrial, with a temperature range of -40°C to +85°C.
The "E" suffix means Extended, with a temperature range of -40°C to +125°C.
The "P" suffix is the package type = PDIP (Plastic Dual-In-line Package).

Thanks Radio Fox.
So if its just the temperature ratings, I can go for the cheaper one since it won't be nearing to these operating temperatures, right?

Yep. Buy whichever one is the cheapest.

Hehe. I forgot about this for a while. In the (huge) process of building an amp+ speakers. When I finish that, I think I'll try one of these.
