Manu changes happened since the last update

Hey! I hope you're doing well. What happend with the two transistors that were removed?

Hi,

I'm well. Hope you are too. :)

If you are asking about Q15 and Q20:

• Q15 was meant to drive the middle indicator when 7-segment indicators are used, which never happened.
• Q20 was meant to drive a buzzer with internal generator, which again never happened.

The rest is more or less the same. Only 4-layer boards and separate wiring for display power is added.

...and, it now supports partial power, which is very important for small instruments like C210, and C105/C115.

By the way, I don't know how to rebase to latest. Any help?

[valerionew]

I was thinking of the edit you did on the readme that removed this paragraph: https://github.com/valerionew/unisolder-notes/pull/32/files#diff-b335630551682c19a781afebcf4d07bf978fb1f8ac04c6bf87428ed5106870f5L262-L264

Q10, Q11: IPD053N08

If you want to change this part, pick a part which has same: package, Rds(on), Vds, and gate threshold voltage.

Also: no problem for the rebase, it'll rebase automaticall when merging

They are there. They were mentioned 2 times in the readme. Some rows below there is:

Q10, Q11 IPD053N08 AUIRFR3607 or IPD12CN10NGATMA1 can do the job.

To substitute this part the important parameters are:

Vds(max) should be at least 75V. Rds(on) should be no more than 0.01ohm.

So, the first one was not needed and I removed it.

[valerionew]

You are right! Sorry about that. Merging

[sparkybg]

Please also rebase the sourse repo. It still points to older one.

Done! For your commodity, it's done on the command line this way:

$ git submodule update --remote
$ git add .
$ git commit
$ git push
