Ungula HOOF

[sixxtus]

Hi, here is my new DIY pedal, built with the Ungula PCB from PedalPCB, with a custom design I made, UV printed by Tayda on a 125B box !

I built it with a Musikding kit, but I changed the capacitors for WIMA and Panasonic ones, hoping for a better result.

The pedal work just fine, and the sound is good (I never tried an original HOOF though), but I wonder why the inside 4 leds (D1 to D4) doesn't light up when the effect is on... Did I solder them the wrong side or what ? I followed the instructions on the PCB with "A" for Anode with the longest leg of the LED, just like for the on/off LED...

Did I make a mistake, and if yes, is there a noticeable sound difference, since the pedal is working fine just like that ?? I hope I didn't have to unsolder this four leds in a such tiny space !

Nice job.

The LEDs won't be getting enough signal to light up, even if they're doing their job.

Try a boost pedal in front and you may see them glow faintly.

Cream pie has 2 that light up.

Super smooth build. Like the design. Great job.

Thank you ! Ok thanks for clearing this up, the pedal works just fine, so I did'nt know what to think about this lack of light from this LEDs... I'll try with an overdrive to see the difference !

Thank you ! I found a free vector image on some website, that I modified to fit for the pedal... That's a lot of time finding an idea, searching an image and make the design, I'm not very familiar with Illustrator, I struggle a lot with it ...

Yeah maybe I solder them the wrong way, I don't know, the symbol on the building doc and on the PCB is inverted... I'll try with an overdrive in front like szukalski said to see if they light up.
The pedal sounds very good though, very happy with it !

Continue using illustrator it only gets easier!

Agreed. I haven’t done a UV printed design, but I imagine it is time consuming. I think your efforts paid off.

Looks good!
How do you like the SHIFT control? I built one of these and I ended up increasing C8 to 15nF. Made the SHIFT control range more useful. Have you checked the collector voltages on the two MP38A's? They can be pretty leaky and might benefit from a bias tweak.

I dig the UV print.

I built one, but with 2n5088s instead of the germanium transistors and the LEDs light up quite a bit when you play. They're just turned off when no signal is passing through.

I think it depends more on the LEDs. Super-brights will glow at 100uA, standard brightness LEDs take a few mA to be visible.

Great graphics execution, great idea for it, too!

Looks great inside and out.

It'ssssss Great Great GGGGREAAT!

For the shift control, that's a good question because I pretty much let it at noon for now, I just finished the pedal yesterday. But since you mentioned it, I try to tweak it a little more today
I think it interacts well with the tone control, especially when this one is turned all way left or right. This two controls can make this pedal very versatile I think.
For the MP38A's I must admit I'm a noob in electronic, that's the reason I buy kits and don't experiment with components, apart from switching for better brands for capacitors for exemple. So I did'nt check the voltages. The pedal sounds good anyway, nice volume, nice fuzz sound, happy with it !

This design was not to difficult to make, two colors with white underneath, and I didn't have to modify the picture too much to make it fit for a pedal
