I finished my 2nd prototype of a Thomas Henry 555-VCO tonight (had to do a few corrections using new unfamiliar solder, so the PCB looks a little bit worn out):

Beautiful, Mattias.

It doesn't look that bad at all. Smile

Nice! So the PCB won't accept DIP transistor pairs? Only hand-matched and metal can?

it is made for hand-matched 2N3906. fortunately ian fritz shared a nice and simple method/circuit with us to do this job...

I've finished three modules this week! Some of the PCB stuffing on these was done in 2012, so maybe that's cheating, but I'm still happy.

On the left is two bandpass filters and a mixer. Center is a new project of my own design. And on the right is EFM 3522 which I'm really happy with.

First completed module of the new year, though I did most of the soldering last year....

Pay no attention to the weirdness with the label Smile

Made a couple of LM386 amps and housed them in honey cans. The one on the left has a bumped speaker and sounds noticably crappier than the other one. Smile

nice speakers! flower

here's my latest finished project, which started out with
Tim Escobedo's PWM circuit and as usual I added some more things to it.
I will probably post some more details later in another thread.
but here are the pics Cool

Great build phobos.

Meant to post this at the end of last year, but... well... things got a bit hectic! I know it looks rough, but as I'm starting out I wanted a usable modular more than I wanted to spend ages on panels, building a proper case etc. Also no particularly esoteric modules just yet, figured it'd be best to get all the basics going first Smile

It's mounted in a flatmate's old CD shelving unit (almost Euro size already), using panels made from a nasty kind of plastic I found loads of offcuts of next to a bin outside a furniture shop. I'll break the bank another day.

Posted Image, might have been reduced in size. Click Image to view fullscreen.

Modules are:

1 x Basic 4011 clock for the sequencer
1 x Dual Channel 4017 CV/Gate/Trigger Sequencer, with built in glide and crossfade between the two CV channels
3 x Thomas Henry VCA
4 x Ray's Cool New LFO (skipped the sine output for now)
1 x Dual Slew (just left over from prototyping the sequencer)
1 x MFOS Soundlab MiniSynth Plus VCF
1 x Transistor Noise
1 x Dual AR Gen
...aaaaaand a crappy 555 osc for a testing sound source. A proper osc is pretty high up the priority list!

Mostly built on stripboard as well, aside from a Ray Wilson bipolar power supply.


Actually, there's another cool project from 2012 I didn't get to post yet, but I need to finish the video first! Should be doing plenty this year too though Smile

Not finished yet, need to check why the LP dose not sounds good with valvucaster overdrive, unlike the BP and HP, that sounds amazing.

I'm working on a small machine based on some of my favorite lunetta chips. He's called V'Ger and is a portable racket maker as opposed to it's bigger patchable brother.

The chips:

1 x 40106 (made 4 oscillators in this set up)
1 x 4512 8 input data selector
1 x 4040 Divider
1 x 4046 built as a pitch tracker based on Nic Collins' design)

Three slow oscillators are the ABC controllers of the 4512. The C controler also has a switch to choose between the slow clock or the output of pin 2 of the pitch tracker.

Another clock with a HI/Lo switch goes to the 4040 to set the octaves that the 4512 will "play".

The 4046 has a Hi/Lo cap switch as well to offer some unique sounds.

I am still thinking about my enclosure; I have a few tins around here so I'll see where that takes me. Here's a crappy video of the device Smile :

That looks fantastic, zthee!

What kind of front plate is that? And how did you apply the text/graphics?

Thanks!

It's aluminium, I used a German company that drills and lasers engraves the panels.

basic 40106 clock (thanks to diablojoy for pointing out the one-shot solution to make it a trigger clock without double triggering like I was when I tried to use a comparator), plus a couple stages of YuSynth clock divider, plus the "super simple S&H" circuit from kickstarter a while back....

Originally was going to be VC Noise + the S&H but I couldn't get it to fit into 1U so that went back onto a different spot on my backlog.

playing around with the S&H and the clock dividers:

i got a very cheap fake PELI case from an electronics remnants online store and decided to make a portable system from it:

I moved house a few months ago and have yet to set up my screen printing gear. However, I wanted to convert a Red Llama distortion clone into module form for convenience so decided to hand-paint the thing. My inner-teenager came to the fore, bringing with it all those years of drawing Tolkien and D & D pictures back in the early 1980s. Silly, but adds some color to the black metal facade.

Looks great. Have been thinking of building a version of the Craig Anderton Tube Sound Fuzz (which the Red Llama is apparent based on) for my system and your sound clips have convinced me.
