My first patch

Today, I've installed the two working YuSynth VCOs into the case. They are not calibrated yet, but for making fun, and some noise, they are perfect. :) The power input of the modules was directly wired to the PSU output pins, but later I will make proper power distributor PCBs.

I've used my existing gear to extend the capabilities of the basic 4 modules of my modular. I don't have a working VCF, so I've used the MAM Warp9 filter, and the Virtualizer, to effect the sound... it's so exciting! :)

My first working module!

Today is a good day for me. I've made success with the YuSynth LFOs! It's actually two LFO2's behind one panel. After hunting down and fixing some problems (a faulty 7555 and some panel miswiring), they are working good, and fully calibrated.

Some pictures of the process, and the completed module:


The case is a 'temporary' lame solution, and will be replaced with a bigger and better one later...

And the pots!

Here we come!

Got all knobs

Now i only need the pots! Soon I will able to continue the modular project!

Wiring

Today, i have wired up some jack sockets.

YuSynth VCOs:

The alignment of the sockets seems correct:
YuSynth LFOs:

A big pack of "ammo"!

Now, Mr. Braska has gone... but today, i've received the parts, which are needed to continue the modular project. A bigger toroidal transformer, PIC for the Midibox CV, 110 jack sockets, a lot of jack plugs, knobs, resistors, caps, etc...

Dual Yusynth VCO front panel

Front panel making, detailed

A few weeks ago, i've made a picture set of the panel making process, so here are the details.

On the table: one container for the acid, and one for clear water, spray paint, panels, wires, 20% hydrochloric acid, 20% hydrogen peroxide (mix it for 1:1).

Cover the back of the panels with self-adhesive tape, attach wires for handling, and put the panel in the acid. Don't touch and breathe the acid! Wait, and check the results periodically. Warning, this acid gets hot after 30-40 minutes of etching (if you do 2-3 panels in a row), it may need cool down a little bit.


Wash the panel with water, and dry it... The height distance between the untouched surface, and the etched one is about 0.2-0.3 mm. I think its ideal for painting, i don't need to etch it down to 0.4-0.5 like the instructables article suggest it.

The surface is now coarse and dry, ready for paint!

Make at least 2 or 3 layers of paint, othervise it can smear off at the next step. Read the instructions on the spray can. I must wait 10-15 minutes between 2 paintings.

After 24-48 hours of drying (depending on paint), scrub off the excess paint with a rough surfaced sponge. If everything is done correctly this can't damage the paint on the lower surface too much, but takes the laser toner layer off with the spray paint on it.


Drill the panel, then clear the surface, and cover with clear coat. This eliminates the small scratches.

Enjoy your panel, and show it to me! :)

Wiring...

The last few weeks wasn't really productive (it's summer...), but i've started wiring up the frontpanels. It's not an easy job for me...

Here are the YuSynth ADSRs, and the YuSynth sample&hold + noise, and the YuSynth ringmod.
