hi, i have been using my ponyprog and self made programmer based on 5.1 zener diodes and 4148 diodes now my hardware is not working ,i want a drawing for ponyprog programmer based on diodes and zeners.

Dear members,
I have a linear variable power supply with unknown brand name that I used for voltage injection.
Then it failed. I discovered that its transistors (Q1 and Q2) are shorted.
In addition, I discovered that its zener diodes are defective.
I can replace the burned transistors.
But I do not know the model of the zener diodes. the model number is not marked on the zener diodes.
Therefore, I cannot replace the zener diodes.
I do not want to test the zener diodes in a test circuit to discover their model or value.
no schematics are available... -
Greetings badcaps community,
I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.
Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.
I have a Elitebook 820 G1 and a Elitebook 840 G2 here.
These ask for a password when entering the BIOS, but boot just fine from the internal SSD.
I learned that desoldering...10-29-2024, 06:03 AM -
This is a shot in the dark, but I was just using my RT809H programmer and it got stuck in a certain state so I power cycled it. Now, the device LED just flashes quickly and does not connect to the software. I've tried to update the BIOS of it and it fails. I went so far as to remove the ROM from the programmer itself but it's some weird chip (I believe ATMEL, but I can't find any datasheet on it) so I've been unable to read the BIN from it w/ my other programmer. Chip has ATMLHC4C56BM CN written on it (I think). I'll upload an image. I have the programmer's BIN ready to program it manually. Anyone... -
Recently I've gotten into EC flashing due to my broken laptop(s) and started frantically searching methods for flashing the IT5571E-128 chip on the cheap(due to me beaing a student and not having a job) and noticed that ITE newer chips can be flashed via ISP (In-System Programming) either via SMBus or the KBC (EPP - Enhanced Parallel Port) interface. While these can be achieved with programmers like SVOD4/3 or the RT809H/F those options are WAYYY out of my budget so I was horrified. But recently I stumbled uppon some programmers on aliexpress that claim they can program a variety of ITE chips...06-17-2025, 07:17 AM

Hi has anyone got the latest software for the TL866CS MiniPro EPROM programmer version 03.2.86 is installed now i have tried the update site in the programmer software but it wont connect to their website i am running windows 10
Edit found this site programmer works now http://www.xgecu.com/EN/Index.html
