Actually these are the exact ones I get from Mouser for 'analog' ICs when I need them. For a controller I would also use something less chic.

Here is a PN for 5mm spacers (nylon) to setup the LCD height, carried by both Mouser and Digikey:

The third PN above was wrong. It's now fixed (110-43-316-41-001000). I took the wrong line from the data sheet and received an incompatible part with only 14 pins!

Just soldered the sockets in and realized that there are both 14pin and 16pin types, so actually four different PNs are required to socket everything:


110-43-328-41-001000, qty1
110-43-308-41-001000, qty2
110-43-314-41-001000, qty1

110-43-316-41-001000, qty1


Now to power up....

I am sorry, I did not include that in the BoM because those things are in my stock and I didn't really think about it. But I should have, of course.

No worries, Jan. They are optional after all.


So another one lives. Really superb fitment with the case, etc. Will add some little silicone feet to keep it from sliding around. Feels like a gem of an instrument and has the looks to match. Nice work!

Well done! BTW I have a few more complete kits left for any new-comers. PM me if interested.

Default A tip and a wish

My unit is up and running and seems to function well.
Great work Jan!

The tip:
Add heat shrinks to the buttons and the LEDs to mitigate false light from the display and LEDs to hit non-actuated buttons. The buttons are quite transparent.

The wish:
The instructions for the calibration procedure in the spreadsheet can be more clear than they actually are. Or I might be a dumb-*ss (my ex-wife will tell you so if you speak to her).

E.g. Display Accuracy, step 1a:
Quote:
Insert 1kHz 1V signal at SE input as measured on DMM at TP7, as accurate as possible
Its unclear what is measured and for what purpose.

Where are other areas in the calibration procedure where the instructions can be made more clear and specific.

A short video will tell more than 1000 words.

+1 on an assembly/ calibration video.

Will avoid all kinds of confusion from lack of experience, or that comes with the territory of written instructions / ESL

Iíve always had the hunch that if kit producers regularly did this itíd add years to their lifespans.

Likelihood is high a big chunk of their customer base are visual learners / painting by numbers in the beginning.
