Logan will be busy until Oct. If anyone has the 5 pin PSU and would like to help us out please let us know and we can tell you how to measure it.

I ordered a Rainbowonic (modified VE-1) from Logan, he emailed a few days ago and said it was on the way soon. It has a 5 pin PSU, when I get it I will let you know.

Ok, did you receive it yet?
I never rush Logan. He will send it when he’s ready, but hopefully soon!

A new one with the original PSU has become available on eBay and I have purchased it. I’ll provide an update as soon as I can.

I also own a Rainbowonic - it’s a great machine.
Logan stressed that I should be as careful as possible with the power supply - and that they are harder to find the unit itself - good luck to everyone trying to figure out the pinout. It’s beyond me but I bet it would help a lot of folks.

If you have the 5 pin PSU, @nsputnik is looking for some help with it…
Also, I hope Logan is ok after the hurricane
Logan has been in LA all week. He drove a Teleglitch he built for a client across the country to California. He’ll be at Desert Daze today. Coincedently, the unit I bought on eBay with the PSU shipped out from an area of Florida that got hit hard the day before the hurricane hit. I’ll get it on Monday.

@nsputnik: does pin_4 go to c2 & pin_1 go to c3 ? when you say positive side do you mean to the + marked on the silkscreen, or actual positve as per the - marked on the cap ?
since in this picture c2 seems to be placed oppisite direction to how the silkscreen indicates:
I do think I meant 4 to C2 and 1 to C3 but I’ll open it again and confirm. Regarding the positive sides of the cap vs silk screening on the board, I don’t recall but will double check.
I just got another unit with a power supply. They are both working so I’ll post my findings soon.

Here are my findings when measuring the PSU pins for DCV.
pin 5 ground against 4 meter’s red lead: +4.95 DVC
pin 3 ground against 2 meter’s red lead: +4.95 DVC
pin 3 ground against 1 meter’s red lead: -4.99 DVC

thanks a lot for this!
i hate seeing working hardware being unusable due to power-supply rarity lol.
just so we are clear:
plug: male
jack: female
There is continuity between the two grounds at the unit’s jack and at the PSU’s plug.
–UPDATE FEB 2023–
There is no continuity between the 2 pins on the PSU’s plug that are outputting +5VDC (4 and 2) nor at the two jacks that receive +5VDC on the unit. Pin 2 is soldered to the board but there are no traces coming from it. It looks like pin 2 is not used. So there is only one +5DCV used to power the unit.
cyberboy666 I see you posted this on another thread but I would suggest you take that down since we are not done yet.

Reaching out to Reddit for help: https://www.reddit.com/r/PowerSupply/comments/xz159k/need_help_creatingmodifying_a_rare_power_supply/
hello,
I’ve also come into possession of a VE-1 recently and am also hitting the wall as to what to do without a power supply. Are there any updates or anyway I can help in figuring out this power supply issue?
I am sure a competent electronic engineer or repair person could reverse engineer a PSU design with all of this info.
I am trying to learn KiCad so I can draw at least part of the schematic.

If you draw up a design I’d love to see it. I’m still looking to build a psu for mine
Any KiCad users or people than can otherwise take a drawing and turn it into a schematic? KiCad looks too complicated for me. What I can do is poke around with a multimeter to follow leads and draw some of it out on paper, post photos, and then either get someone else to make a schematic or get the drawings to an engineer to help us understand what is going on.
If you have a unit you and would like to help you can do the same thing.
I have created a GitHub project. It is my first one so forgive me if I did not do it right. If you know what to do I’ll add you. Videonics VE1 Schematic and power supply build · GitHub
