My oldest daughter is home sick today so I'm not sure how long I'll be able to spend in the shop working on this. I jinxed myself by telling you all I would have a rough schematic today... I'm sorry. I may still get it finished, she is normally OK in the house alone. I just have to e how she is doing.

Thanks for understanding.

Ok, very rough first draft of the schematic. I will spend the next few days trying to clean it up and make it a bit more readable.

Here is a much more readable version of the rough draft above.

schematic v2 click

I'll start board layout tomorrow, have a busy afternoon today.

Thanks,
Jason

Well, I did have the layout all done and routed. I exported pics, re-saved everything and then went about copying all my data to my several backup locations. After I saved my backups I realized I had been working on one of my backup copies and I actually copied an earlier revision back over the new work! I even copied over many of eagles automated backups because I just back up the whole project folder. I managed to recover one backup from about an hour and a half before the attached screenshot... I'll get back to it again tomorrow and knock it out again.

Ok, I finished it again. Lol, I hopefully will avoid doing something stupid like yesterday... Anyhow, attached is a copy of the overall layout as well as images for toner transfer if anyone wants to try to DIY one. Also the front and back layout are linked in a PDF. I will probably send this board to be made as soon as I finish up one more driver card I am working on.

Updated schematic(click)

Toner Transfer layout PDF(click)

Later,
Jason

I got bored today, so I knocked this out too. The amp I bought for this driver board came in with one broken power shell. I drew all three of the shells so I can 3d print them. I typically do this any time I get an amp in that has broken plastic. I have a wide variety of stuff already available, so drop me a PM if you need plastic parts...

I 3d printed one of the larger ones so you can get an idea how it compares. It's still far too cold out, so I only printed one. Have to keep the shop fairly hot so 3d prints don't fail, and I can't afford to heat it when it's 4 outside...

Boards are done and have arrived. I'll populate and test soon. Ir21844S drivers are in short supply right now though, so it could be a little while.
