Repair / Re: Replacement for Fluke 845AB OPR switch?
« Last post by tatel on Today at 12:21:34 pm »I found your videos about F845AB quite interesting.
It's perhaps a lesser bad that the broken switch is a quite simple one; after looking at the picture, one could think at least a couple way to fix it. Thanks for your suggestion, I'll look at it.

Microcontrollers / Re: Attiny1606 burning out when connected to a drv8251
« Last post by MarkF on Today at 12:15:36 pm »There doesn't seem to be anything wrong with your latest schematic.
Barring any connection issues, it seems like the DRV8251 may have been
damaged through all the other issues found thus far.

Test Equipment / Re: HP Logic Analyzer Inverse Assemblers
« Last post by Nemesis1207 on Today at 12:10:22 pm »There didn't seem to be any tool in existence that could create a "HFSLIF" single-file image for these HP systems, which means while it was possible to transfer the existing inverse assembler "images" in this thread to a HP unit via FTP, the only way to get the "relocatable" versions of the inverse assemblers onto the system in a format it would recognize was to use IALDOWN.EXE, which only supports serial and GPIB, and even then only within dosbox or on a native dos system. I found that annoying, so I wrote a command line tool to go straight from a .A file to an inverse assembler file in a HFSLIF image. It's written in C# for .NET 8, so it can compile and run on anything. Here's the github repo:
https://github.com/RogerSanders/HFSLIFWriter
The tool itself is currently geared to these inverse assemblers specifically, but the code is generic and with some trivial changes it could support packing any kind of files into these HFSLIF images, if that ends up being useful to anyone. The code itself describes the image format well, so it'll serve as useful documentation if nothing else for anything that comes after.
For convenience, here's a pre-compiled Windows exe that's been compiled down to native machine code with no external .NET dependencies or anything else:
https://github.com/RogerSanders/HFSLIFWriter/releases/download/v1.0/HFSLIFWriter.exe
Usage as follows:

Usage as follows:
Code: [Select]
Packs a relocatable HP Inverse Assembler into a HFSLIF file structure, suitable
for transferring to a HP Logic Analyzer via FTP. This program provides an
alternative to the HP provided IALDOWN.EXE file, which only supports uploading
via a serial or GPIB connection.
usage:
HFSLIFWriter.exe inputFilePath outputFilePath fileDescription invasmFieldOpt
inputFilePath Path to the relocatable inverse assembler file on disk.
Usually a ".A" file as output by ASM.EXE.
outputFilePath Path to write the generated HFSLIF file to
fileDescription A file description up to 32 characters to display on the logic
analyzer when listing this file on disk.
invasmFieldOpt The control setting for the invasm field. Usage is the same as
in IALDOWN.EXE, a single character of A,B,C or D must be
specified as follows:
A = No "Invasm" Field
B = "Invasm" Field with no pop-up
C = "Invasm" Field with pop-up. 2 choices in pop-up.
D = "Invasm" Field with pop-up. 8 choices in pop-up.5
Repair / Re: SONY DVP-S9000ES dead
« Last post by wasedadoc on Today at 12:10:17 pm »You need to confirm if those voltages are present on the board or not. The connector is not the only place you can measure. If you cannot access other points when the board is in situ and powered up, temporarily solder some lengths of wire that you can bring out to your meter.

Repair / Re: Ksger T12 Sudden Death
« Last post by BrokenSolder on Today at 12:00:34 pm »Sorry for the late reply I've just checked U5 it has 21v going in and no 3.3v coming out, the chip is a SE8533 1831-HF I'm hoping I can find it somewhere easily like Ebay or an equivalent, would there be an alternative you guys or anyone else can recommend that would be better please?

Beginners / Re: PCB review and RF layout
« Last post by tszaboo on Today at 11:59:20 am »Download Saturn PCB toolkit, and enter that RF trace into the trace impedance calculator. You need 50 Ohm. I don't think you can get 50 Ohm on a two layer board with reasonable trace width. This is a coplanar waveguide for the calculations.

Microcontrollers / Re: ELM327 (serial to OBDII CANbus converter) discontinued
« Last post by coromonadalix on Today at 11:57:32 am »A car as 2x can bus lines, with 2x different speeds, even if you have can bus adapters
It is the software who help a lot for obd2 functions, it will not work the same as can bus interface, i have the "usb2can" module, sure you see the data streams, but you have to decode it in a sense, and to know from whom it came and where it goes etc ..... you work at another level
Like when people want to add some speedo projects, more modern dash interfaces etc ...
ELM327 was doing the "magic", and with obd2 software tools you could do ECU AC Air bags ..... functions, and many other things
yeah me too i should have bought the last v2 chips before they gone out of business,
I do have some adapters who have the real ELM design, minus the latest v2 chip version ... the v1.5 leaked and now many pretend v2 etc ... which are all fakes, unless as i wrote you find an genuine one.
You are stuck buying real obd2 tool like Autel, Foxwell, Creader, X431, Launch, VCM2 devices and many others "genuine" ones with frequent updates ....
I have an Suzuki VCM2 who do Ford and GM cars, but not others ... and i paid a lot for it
Ultimate devices who support all the Can protocols ( Iso, Kw, SAE) will cost $$$, J2534 interface(s) where supposed to offer that at lower prices ?? obdexpress is a good place to find many things but ... not cheap
Not a 10-20$ "ELM" device
