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.
