Anyone still selling parts kits for the UHU Servo Board?
Is it possible to use inductor PM2120-2R2M-RC insted of PM2120-1R2M-RC on UHU HP (L1,L2)?
To clarify the value of the following components C14 and C18 (tantalum or electrolytic)?
What are jamper's (RST1 and P3) on PCB's for and if it's necessary to install (to short-circuit) them?
For HP_UHU only: C14 and C18 could be tantalum capacitors. RST1 is a reset jumper and should be normally open (briefly closed for hardware RESET). P3 is a test point for GND potential, it is permanently shorted on the PCB by a thick copper trace. P3 serves as a test point GND for the oscilloscope, and as a auto-router trick to separate Power and Logic GND while auto-routing the PCB.

Kreutz.
Hi,
I've finally gotten around to assembly of the first HP-UHU and have made up some sheets with colour coding for easily locating where all the parts go. Once the first board is up, I'll scan them and post to make it easier for everyone else (and me for the other 3 boards).
There are a couple of problems though. I've downloaded several zips with component layouts. On one, the PCB is marked Rev 0.10b while the green Rev00c 08/2007 component layout doesn't match the board. Instead I've been using the monochrome Rev 1.00 12/2007. However, it's missing R46 right by J7.
Next, the component list has C21 etc. listed as using a 5.1X3.2 footprint but in fact the caps on the board are on 0.1" spacing. What is the part # (or is there one) of the 0.22uFd MKT capacitor that fits this?
Any chance that an up to date version of the component overlay for the PCB marked 0.10b can be posted. Then I can transfer my coloured marks and labels it it along with Digikey and Newark part #'s.
Thanks

I got caught that way once with 4N33s. In that case the pins were wrong on the schematic object and so the layout was wrong. Expensive mistake.
Here's a picture of progress so far. Just needs LEDs, ICs in sockets, 470pF, 1uFd 250V on bottom along with transistors and voltage regulator. Already the circuit boards weighs an extra 150 grams.
Now to make a list of what parts are missing for the rest of the boards.
Looking forward to trying it out.
John
Thanks. I'm only sticker inner person. You did all the work.
BTW, I've requested a price quote from www.thermoflo.com for 6.5" lengths of their E1197 heatsink extrusions. It's 5" wide and looks like it may be perfect for the HP-UHU.

Hi; could someone please point me to a place were I can download the instructions to build these boards and the parts list?
Thank you

I don't think the boards for the HP_UHU are available anymore. Kreutz was the designer. Likely he may have a web link to gerbers etc. for making more boards. I can email things like parts lists etc.
