I detest working on car rust, whatever you see it's almost always 10x worse, from the inside out in most cases. We have had great success with Krown rust. At their Mississauga location they had pictures of a pristine 72? Datsun in their show-off pictures. Those things would rust in the Arizona...

We sent our kids to private school, not a stuffy one, just one that focused on mastering the basics and excelling to whatever level capable on a student by student basis. Our kids received a superb education. Non of the crazy crap that was going on at the time in the public system. For example...

When I was doing undergraduate Engineering we had to take an unrelated elective, so I choose political science. Our professor was clearly a very hard line communist. I tried to be open minded and even put a leftist twist on my responses during class discussions, I had an A+ going into the final...

Regarding E117-01 (the updated PCB with differential input capability) The manufacturing files are available for this board if/when someone is interested. IIRC someone was about to place a PCB order for an unrelated board, so adding this board to an existing order should incur very little cost...

FWIW Having power saving to USB ports enabled, can cause a lot of problems like this, that's one setting I would look at.

Agreed any board spin has some risk, that being said I'm batting about 95% on the last 100 designs. This is a really simple board (almost brain dead simple, okay I just tempted Murphy) ;-) Someone offered to include this PCB in their next PCB order and that makes a lot of sense to me, will...

Okay a little update..... The tested E117-00 boards ship to Tom tomorrow. No modifications required;-) I completed the E117-01 (Improved board), see attached schematic and BOM pricing. Assuming we build a minimum of 10 boards, component pricing is as follows (Digi-Key prices as of today): US...

Tom, It would be quite helpful, if you could post some instructions for the ESP32 programming procedure. Assume a Windows PC without Python installed.

Djberta : 2 MickeyF : 1 DavidR8: 1 ComustableHerbage: 1 Susquatch: 1 ----------------- Count = 6

Djberta : 2 MickeyF : 1 DavidR8: 1 ----------------- Count = 4 BTW I just eliminated two more components, down to 24 total, 10 types

Djberta : 2 MickeyF : 1 ? DavidR8: 1 Count = 3, possibly 4

If interested please quote this and add your name and qty so we know where we are. Djberta: 2 MickeyF: 1? Count = 2, possibly 3

This is about how an improved version would look... + A bit smaller than the original + Only 26 vs. 73 components on the original + Differential signaling + scales plug directly into PCB I suppose I could use a larger version of the one small IC, and that would make it easy to solder for anyone...

Not sure, but these (same part # except the "AS" use differential quadrature (same as Ditron and that's what I'm using on my lathe)...... https://vi.aliexpress.com/i/1005006196081659.html?gatewayAdapt=glo2vnm

Looks like you have everything, except... The schematic as provided by Yuri? requires some components to be populated and some not to be populated depending on the type of scale used. I'm not sure how many people actually use the "cheap" 3v3 scales, I know I wouldn't. If this proceeds I'm not...
