BSIDE ESR02 Pro Transistor Tester (teardown & quick test)
sorenkir:
Hello,
I have bought this small device ($22 shipped):
It is cute (wine red box, as stated on the box, I like that ;) ) and well thought: external 9-12V DC jack, test probes jacks, SMD socket, plug-in sockets, discharge resistor, ESR chart (on the back).
The two buttons have the same function: for left & right handed :-DD.
A few additional functions:
The most useful is the "continuous" capacitance/ESR meter (C+ESR): no need to press the button for measurements.
Even a decent "user manual" is provided:
Don't turn it on, take it apart:
Atmel MEGA328P, LM339 comparator, AMS1117 3.3V & HT7150-1 5V LDO regulators:
Quick test:
330? resistor:
10mH inductor:
SMD 1mH inductor:
White LED:
470 uF capacitor:
Transistors:
Not impressed by a big power NMOS:
No accuracy specification but measured values roughly agree with other instruments I have. Ideal for component identification.
Michel.
Gyro:
Quite a nice case variant of https://www.eevblog.com/forum/testgear/$20-lcr-esr-transistor-checker-project/
CustomEngineerer:
Hopefully didn't cost more than $20. :-DD

I find it a quite neat interpretation of the original "Komponententester" by Karl-Heinz Kübbeler.
I made one myself in the past:

Tooling yourself a nice (handheld) case isn't normally achieved at $20, so the price looks good to me. :box:
Regards, doc

Likewise. I picked one up a couple months ago and have found it to be well executed and quite useful.
