| And Ikea Bittergurka as enclosure is a great idea for my next

| This is amazing and super inspiring. I love how such a

| Does anyone know how one would print the black text on the

| Hey Mobeets, Zimo (author/builder) here.
|
| The text on the flowerpot and the wooden box was "printed" with
| toner transfer method. It's a super simple process: you print
| the text flipped with a laser printer and use toner transfer
| solution and rub the text on the surface.
|
| I used this solution for it (hope it's fine to share it):

|
| Here's a video how it's used:

| So far the best place to discuss things is under the build

|
| In short I assume anyone who wants to build this synth
| generally understands the concept of subtractive synthesis,
| basic electronics, can read schematics and PCBs (using KiCad)
| and has experience in soldering. I've written a build guide
| which has a "prerequisites" section as well as details on how
| to order PCBs and assembly steps: https://www.shmoergh.com/hog-
| build-guide/
|
| The schematics might also be a good resource to dig deeer and
| understand the building blocks of an analog synth.

|
| All joking aside, any suggestions on a fun starting project?
| I do understand subtractive synthesis (software side) and
| music production and your project looks so fun, but
| definitely out of my league. As a fan of yours, I'm
| interested in any suggestions you have on jumping in. But,
| I'll keep reading about HOG until then.

| germanic, "oe" is the "o". So this gets even more weird. Haha.
| Nevermind! :-D I love such projects. Very well done! Looks
