locky_z,
Where are you located?
Can you sell to Hong Kong as Sunsun22 said? How much as kit or assemblied pcb kit?
If your s/w are structure enough, I can help to translate your "display manual" subroutine. Or we translate your PC display on MS word etc and you do the s/w code.
Mark

No one interested in making it available to the rest of us, despite all the volunteers for translation ?

and some interesting measurements of Toshiba Dual FETs :

One more (more relevant) link :

[]뵼ͼʾ - DIY̳ - HIFIDIY̳ - Powered by Discuz!

In post #140 (July 2009), it was mentioned that the local market had been saturated; once one per week.

I still could not find the Group Buy thread yet.

Evul, thank you for your effort and input.

It looks like the project has been started since June 2008 and went through a number of revisions. Locky_z is located in Xin Hui which is a remote town about 1.5 hours by car from Guangzhou City. He is selling this in China only. I am translating his message as stated in the marketplace forum as follows: -

QUOTE
This is my own design and product.

This module can measure the followings
1. Curve characteristics of BJT, FET Vbe-Ic, Vgs-Ic, Vce-Ic, Ic-Hfe, Ib-Ic
2. Forward and Reverse V/I characteristics of bipolar components – LED, diode, resistors
3. Curve characteristics of 3 pin regulators (positive, negative, fixed or adjustable IC)
DUT voltage up to 36V, current 1uA~>=2.5A.
Precision is better than oscilloscope.

Brief usage description
User needs to provide 30-40V power supply (regulated, 2.5A). Connect the module to your PC’s parallel port (25 pins). You must use physical LPT port because USB to LPT converter does not have real address. You can use PCI LPT card or PCMCIA LPT card). Copy the software (CD or download link provided) to your PC and install it.
Insert BJT as shown on BCE socket. (For FET, G=B, D=C, S=E). Input your measure criteria to the software and click to measure.

Due to cost control, some second hand components were being used.

Please refer to the following link for GUI.

UNQUOTE

My observation - The cost ex-work is RMB310 (approx US$46 but you have to know Chinese because GUI is in Chinese.

I found it as well. We tried to get in touch with him.
Will let you know if we can convert to English plus a few more refinements.
Let's wait and see. Be patient.

The inside is more interesting. The outside has potential for improvement.
