Component checker / tester

Everyone knows the problem: You have a transistor, but you can't read its signature. Or you can't find the datasheet... You have a diode, but... You have a capacitor, but you can't read... Here is a smarty solution.
Features
* Automatic Detection of NPN and PNP transistors, N-and P-channel MOSFETs, diodes (including double diodes), thyristors, triacs and resistors.
* Automatic detection and reporting of the pins of the test component
* Detection and display of protection diodes for transistors and MOSFETs
* Determination of the amplification factor and the base-emitter forward voltage of transistors
* Measurement of the gate threshold voltage and gate capacitance of MOSFETs
* Show the values on a text-LCD (2x16)
* One-button operation, automatic shut-off
* Power consumption in off mode: <20 nA
This tester also supports diode measuring, R/C testing, and a lot of other components identifying.

Wonderful project. Who offers
Wonderful project.
Who offers it as a whole kit?
Following the forums in German is difficult.
The English translation was lost in the shuffle.
Because of the language barrier I would consider it only as a whole kit. Including a programmed chip.
Very nice.
Thnx.
An unnamed compassionate soul
An unnamed compassionate soul in Germany took pitty of me and help me purchase my kit, including a programmed chip. : )
Now I am trying to put it together from what little German I understand. What plastic case did you use? Any chance I get feedback from whomever put it together for you guys???
Many thnx.
I'd like to build my own
I'd like to build my own tester next week, so I'd make 1-2 kits more - just a PCB and programmed chip. I'll post my offer here, so stay tuned.
