That looks fantastic!! Wow!

Yes, looks great, I managed to get mine partly working this weekend, a small success.

Looks nice! What type of material is this made of and how did was the text ‘printed’ on this?

A modification of Ray Wilson’s method. 1/16" sheet aluminum, graphics printed on paper and glued using spray adhesive. (You can see the seams: This panel needed three sheets of paper.) Then matte finish self adhesive transparent plastic on top of that.

It’s the second panel I’ve made this way and the first was much smaller (well, duh). I was concerned I might get bubbles or wrinkles in the plastic but it worked fine. For some earlier panels I used contact cement (Wilson’s recommendation, too messy) and paper that either had been laminated (also Wilson’s recommendation, too thick and too glossy) or sprayed with clear paint (more time consuming, harder to control, not as good a surface). This approach is my favorite so far — aside from PCB fabrication, but no way was I going to pay for five 800 cm^2 PCBs and use only one.

That extra hole is now hidden. Wallpaper covers a multitude of sins.

Looks great, figured it was PCB!

I’ve been 3D-printing my panels but have not found a satisfactory solution for the graphics. Your approach certainly looks good.

From a design perspective that is another great suggestion. Why not use wallpaper? This could give the panels a common look like they are of a certain brand. I tried to find a ‘look’ when I was making my VCV-rack vocoder module, and would like the same for my hardware modules.

Well, not all of us have a CNC router and a sheet metal folder. (Yet.)

Layered prints? Lot of prep work and has limited resolution so you probably need to limit yourself mostly to symbols, but can look pretty cool. Here’s a video (slicing and printing starts just after 10:50, the bits before that are about preparing the graphics):

Let me know when you get your 8-step going, ill start messing with mine again. I need to tweak the arduino code values I put in for the rotary selector. I get 6 steps twice and random 3 times. Otherwise that first code you gave me has worked great, stable for the last couple months. At least in 8 steps and the cycling and random. So all the best parts.

Gate grinder + 8step + quantizer is a pretty good setup for your sequencing needs

As long as all the resistors in the chain are equal, the values I put in the code should work. They did at one point.

looking very nice :wink:

I am hoping the next boards for my “cheap step pro” will arrive this week… then it’s only the brain front panel i need to finish and order…

Maybe it’s been mentioned somewhere earlier, but what schematics are you using?

thanks, I’m impressed with myself, the only error was a speck of solder causing a short on the cymbal circuit. PCB’s will be nice, but I was already committed on these.

Seems to work, guess I can put the rest of the nuts on! @CTorp

Nice! I was worried I was going to be flabbergasted when your #7 LED was stuck on

All these red and green lights… Alright who is going to incorporate a Christmas tree into their front panel design?
