Mega M328 328 Atmel.
Those little useful component testers
- what is this 3 legged thing... it will tell you..


That red one was the first one I ever got; mine was preassembled tho. Postmortem revealed the 3.3V reg was dead short and the Atmega328 took it personally. Shocking. That's when I got the Yiwangia unit you guys may have seen on my bench; it came built into a recycled caller ID shell. That one runs on a recycled puffy LiPo from my Delta wing.  :-DD

   

https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2060353.m570.l1313&_nkw=ESR02&_sacat=0

https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313&_nkw=DTU-1701&_sacat=0&LH_TitleDesc=0&_osacat=0&_odkw=DTU1701


Since then, I've upgraded... got one of these BSIDE ESR202 Pro units for CAD$27 WITH the tweezers; vendor had the black one on sale, and the red one $10 less for some reason.  :-// Only took 3 weeks from China. :-+

I highly recommend it; the ZIF socket pinout on the 328 Component Tester is a wee bit confusing; the slots on this one are much more straightforward. Also, it reliably tests LEDs and generally gives more consistent results than older firmwares.

But the big thing for me is the SMD test panel being all up high and easy to get to; that is just... the shit. Nothing else makes testing tiny chip parts as ... well, not easy. I'm too old and too bad eyesight for it to ever be easy again.  ::)  But at least it's not like volunteering to get kicked in the junk over and over again, like most handwork with SMDs is. :-DD  I can reliably get valid results even with 0602 and SOT-23 parts using this thing.  :-+

EDIT:    I forgot... this thing is also available one eBay & Aliex as the DTU-1701, often for a few dollars cheaper. Usually can still be found ~US$25-27 net if you shop carefully. Look for V3.1 or newer.

I feel your pain.

The best stuff I've ever found for repairing plastic is this:  https://www.amazon.com/Devcon-22045-Plastic-Welder-Dev-Tube/dp/B003NUGL9S

It smells so evil you just know it has to work.  And it does.  I've even glued paddle switches back together with this stuff, strong as new. This product has a shelf life of a year, make sure you get fresh stuff and you're golden.

Too thick. I need the wicking action of CA. I have a bottle of Bondene ABS welding solvent on the way; I just need to stop glancing over to the the side of my bench where the 54645A sits, mocking me. :o

Are the specs on the listing correct, it only does 0-50 \$\Omega\$  :wtf:, what about the ESR of caps?

I expect it does and this a classic case of a lazy seller?

The urethanes can also be used to strengthen something on the back, even if you pieced the jigsaw back together with CA for aesthetic reasons.  Basically cut a V groove in the crack on the back, and fill it in with the high strength stuff - and you get the best of both worlds.

I'm having one of the earlier models of these universal testers. As Spec wrote, very useful for repairs and for characterizing unkown parts. I've putted mine in a Bopla case and created a little storage for the testing leads.

The DUT here is a TIP132.




BU508A, I strongly advise to give some consideration to the wellbeing of your ears!

Almost all the vendors quoted 0-50 \$\Omega\$, some quote nothing but I did see one or two that quoted 50M \$\Omega\$ which is a bit more like it. Quite an interesting item through but for now, I'll stick with what I have.

Och menno! Nix darf man! *kicking little pebbles*

In my defense, I was left unsupervised.

And the enclosure from Bopla is no Klemmenkasten, it is a Euromas II EM 217 F and even Bopla is offering feet for it.

Hoping, this time my ears will be left alone.   ;D

Oh, I wasn't suggesting you should kick yours to the curb; I was just promoting my current favorite for folks who are actually looking for such a beast or who might have a few TEA-assignable shekels burning a hole in their pockets. ;) I bought mine primarily because my collection of the things are still in a trailer in Buffalony.  :o
