content: Hello, I decided to restore Keithley 179A, and front panel needs to be re-done, since old is all scratched, faded and cracked.So I need some high quality image of their logo, so I can re-draw it in vector, or if someone has it in vector, I'll share complete panel stencil in exchange, when finishedLooking for this, in good quality.

content: Quote from: TimFox on June 17, 2022, 09:22:12 pmYep, I was also unsure if it was "regular" or "soft regular", that's why I posted the image.It's definitely "colt" though, and it's gotta be easier than trying to trace it by hand.

content: The fonts are not quite right. The serifs are rounded.For a worthy restoration project, I would make it vector art. The fonts are a good starting point, which I would outline and continue from there.

content: Thanks!I think Colt regular light - suits well. There are some subtle differences but I think, they don't matter that much.I'm also planning an upgrade module for display, since old one has low brightness and I don't like red color that much anyways.So I'll make a drop-in module, but have not decided what to do - either equip it with high brightness, modern 7 segment LEDs, or use some OLED display, which will be also capable of displaying say "Out of range" instead of flashing 0000s.

content: Quote from: Fungus on June 18, 2022, 12:29:03 pmIt clearly isn't. It's closer to Courier with the rounded serifs, the soloKespecially. That would make some sense from a TE pov as that and the Univers fonts both had some connection to the same designer, and were made for IBM, way back when. The K in Keithley looks like a modified lower case Courier k.There's a fair chance it's a modified version of a commercial font so that Keithley didn't have to pay for a license to use it, though as I understand it IBM didn't copyright the Courier font anyway.It's probably superfluous to point out that the Colt font was designed for Adobe, so the Keithley use predates it by decades, but I'm sure you already knew that.There's a version of Colt Soft that is probably the closest you'll get with a modern font:https://blogfonts.com/colt-soft-.font

content: I will be ordering custom silkscreen printing. These replacement panels will be made from special, "instrument-grade" cast acrylic (original one is made from cast polystyrene), which will pass not only red, but green and orange colors too, in case owner decides to upgrade the built-in led module. Which I'm going to do - I'm currently developing an "drop-in" module, which will be plug and play, but house larger size, more bright led indicators, with several colors available (green-orange-red, have not decided which one yet) and with automatic brightness option.

content: 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.

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’sNice work recreating that logo from the font

So I have laser cutter/engraver, some CNCs at my premisesCorel Draw is a great piece of software, except there are some bugs they haven't fixed from the period it was available on floppiesHere'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.
