DIYA store "Wolverine" (Son of Badger) .... suggestions ??

[Harry3]

I believe I did find one problem on the BOM, just so everyone knows. R126A, R126B, 127A, R127B, the first first recommended resistor is a 10R, pretty sure that's a mistake, schematic is showing two 20R in parallel to total 10R with EF3-3, the EF3-4 adds a 10R in parallel with the first two.

Good catch. I'll change the value in the BOM.

Hi Guy's Harry has updated the bom, please download it from the dropbox folder - "Updated BOM 2022 March 27.xlsx"

I am sure everyone else knows the answer to this, but I don't.

There are choices to be made in several areas based on whether you are using "For drivers 2SC/2SA" or "For drivers MJE1503X/3X", what if you are using MJL2119X?

If you are talking about the MJL21193 and MJL21194 they are a TO-264 Package the drivers are a TO−220 Package.

MJL21193,94 are slow devices,i don't believe that are suitable for Wolverine.
Trying MJL21193,94 in Slewmaster in the past i smelled the smoke...

They're listed as two of the preferred output devices on Page 2 of the BoM.

Nevermind, I am an idiot, was so focused on the devices part numbers, I didn't read Output vs. Driver heading.

I have updated the second page in the BOM, showing the output transistors that were tested or simulated. Hope that helps.
The MJL21193/94 transistors would not be my preferred choice and that is why they are not included in the main page of the BOM.

@reddish75 thanks for waiting.

These are the final hole locations for everyone's reference.
They show all the holes for the Wolverine EF3-3 & EF3-4 relative to the UMS (universal mounting system) which is used by the stores for their Heatsinks.
Please download the zip file to extract the DXF file.

For those who don't know a DXF file can be loaded into a CNC mill to automatically traverse in the x - y axis to locate and dill the holes accurately
if you are using your own Heatsink for the Wolverine Project.

Thank you, all clear. I did order the NJWxxx parts because they fit the settings I was looking for, and they were listed in bold with asterisks showing **recommended. I know you all split up the workload, but perhaps if the parts are not recommended, remove that bold and asterisked notation also. It may remove some further confusion. Not sure if that fits into your area or another's.

I understood that as "if you're using these outputs, it's recommended to use MJE drivers".

 

[ItsAllInMyHead]

^ That makes perfect sense! See how easily I get confused. Thanks!

Hi Stuartmp, What does mean of Parts ID named "Chelp" , "Qhelp" , "Clift" , "Rlift" , "Rhelp" in Wolverine input section ? Does it an optional or mandatory ?

Mandatory. They just don't have a numbered reference designator.

Noted and thanks JJs

Apologies if its been covered in this thread before, Is there a "typical example" build that has been done detailing all PS caps, TX and semi's to use? i.e. taking the options out of the BOM

 

[stuartmp]

Hi Guys,

Good news.

The fabrication of the group buys PCB's is now complete.

 

[rag1]

Hey Stuartmp,

I have not received the build manual or the BOM. You mentioned about a Dropbox??

Thanks
Ron

Did you check your Clutter and Junk folders?
