Keithley old logo in good quality someone?
<< < (9/10) > >>
LinuxHata:
Yes, this is done with laser engraver doing outline + paint filling later the groove.
Looks acceptable for me. Will re-do with more darker acrylic, when the PCBs for upgrade kit will arrive - there will be larger, and more brighter, green led indicators installed.
It is amazing, that this device, made back in 1982, is so accurate - tested it with resistor kit with 0.01% precision and it falls within range for both ohms and volts, but has little error on microamps, which gets worse, as device warms up - initially, instead of 1000ua, it shows 997ua, but after 1 hour of continuous use, it shows 992ua. Volts and Ohms do not show this behavior. While I will be using amps measurement very rarely, I don't care for that that much, but should I consider that things might get way worse with time?

And how to remove the buttons? they appear to be sitting very tight. This is disappointing, since I've ordered a pack of replacement ones, since original ones are way too yellow.
Old Printer:
I built a HeathKit DMM about that time and it looked remarkably similar. Unfortunately at some point over the years it has disappeared. I manage the production department for a sign shop, we have lasers and flatbed UV printers. I was wondering how I might be able to help you out, but it seems you have a good handle on it. I got this job years ago because I was the only applicant that knew how to use CorelDraw. I have been using it since it came on 3-1/2” floppy’s :)  Nice work recreating that logo from the font  :-+
LinuxHata:
Thanks!

My knowledge in graphic and design is far better than my knowledge in electronics, which is my hobby. So I have laser cutter/engraver, some CNCs at my premises :)
Corel Draw is a great piece of software, except there are some bugs they haven't fixed from the period it was available on floppies :D
Here's my work - nixie tube clock, designed in Corel Draw, and later made using CNC. I made this to support Ukraine, and all income from sales were donated to Ukraine.

That looks great! I wish I had the space for a cnc hobby, particularly using wood.

Double thumbs up from me :-+ :-+
LinuxHata:
I bought a CNC 2020b kit  from China - it's work area is 200x200mm, and it requires space on table of an average laser printer (but it is way too noisy for bedroom use, for sure :D)
