Subject description: Elektor Oscillographics + TV
Reply with quote  Mark this post and the followings unread

I just finished the Dronoscope (well 99%, I need to replace one switch for aesthetic reasons)

It started out when I found the Elektor Oscillographics circuit (posted here)
I have a couple of small TV's which I was planning to use as visualizers
(maybe even make a synth module out of one) and this seemed like a nice
circuit for it.

I first started working on the elektor circuit itself, and made some small
modifications to make it more usefull for drones. By itself it produces nice
visuals and a droney sound but the fun starts of course when you
modulate it. So I started making some LFO's then some VCO's to change
the sounds some more, a filter seemed usefull and after a couple of
months I made so much extra stuff that I would need a really big case to
fit it all in. That's when I saw the beautiful boxes build by Captain Biscuits
and this made me decide to cut the whole project into smaller parts.

I had a really nice case i found at thrift shop and the TV just fitted in so
I worked with that. It was quite a challenge to get everything in and
especially how to mount the TV tube.
but Im VERY happy with the result. Laughing

The TV is still in working condition and it can also take external deflection
signals. The amp of the TV can be used for other signals and it's
attached to an internal speaker. I also amplified the TV audio to 10Vpp so
it can be used as white noise if you don't connect anything to the antenna
input. And there is a comparator circuit in there aswell to convert the
noise (or another signal) to a square/pulsewave.

Here's a demo video (I'll probably make it longer later).

umschmitt - That synth sounds awesome. I thought the DS7 clone was a drum module, but yours sounds like an awesome little bass synth too. Does it do both? could it be cv controlled as a bass synth?


Phobos - absolutely amazing job! That is so cool and looks very professional. And the pong is a nice touch too Very Happy

Many thanks ! That was the idea : make it a dirty and usable little synth. Yes, it still does the «vintage» drum module sounds, now amidst many other things… (some of them not fully explored yet !) Voltage control for the pitch is a classic mod here (I have hard times setting the MCV24 for a decent tracking range, though) ; I also added another CV input for VCF or VCA modulation.

I do agree. I love those spirals !

the second one has some nice spiral action.


Cool

Wow! I love that dronoscope, super cool.

Here is a project i built after pouring through all the great info that Jurgen Haible has left us. I wanted to do a sort of tribute project incorporating some of his ideas, and came up with a tabletop filter unit.

It has a pair of low pass filters that can be used separately, in series, or in parallel, inspired by the descriptions of Jurgen's JH-5 synth.

Each filter gets its own LFO, with three modes of LFO modulation (LFO A to VCF A, LFO B to VCF B - LFO A to both VCFs - LFO A plus LFO B to both VCFs) The summed control voltage to VCF B can be either inverted or not, for low pass panning. LFO A uses the trick from the SOST flanger, with a three position switch for triangle, slewed square or sample and hold.

There is an NE570 compressor and JFET distortion per side, using dual pots and sharing a knob.

There is one NE570 enveloper follower normalled to input A, with attenuverters to send the envelope to filter A and B.

Storing cigars ? I guess it's about my tour de force, then (or am I wrong ?). Thanks a lot ! But it's a small thing compared to the masterpieces presented on this topic (including Jingle Joe's post nuke farm punk design). I definitely need to post more examples of what this box offers soundwise. The percussive sounds - with triggering signal modulating VCO or VCF - are quite cool. And output fed back in the filter, mmmm…
(one can notice here that I'm rather satisfied)

I've actually had a very productive year getting some modules finished and working, but I've been very lax in posting them on here.

Time to fix this, so here goes with the first module I finished this year, an Oakley Ring Modulator.

This is an early board I won in a raffle at the Synth-DIY UK meeting a couple of years ago. It appears to be a FRAC style layout for the pots (less than the MOTM standard), so I had to use smaller knobs than usual for this module.

I've actually had this built for quite a while, I just never got round to testing it.

That's one down, now for the next 60 odd.

Another completed build to add to my system. This time it's a Thomas Henry SN-Voice.

This was probably the second module I built, probably over 2 years ago, but it has been hiding in a corner as I couldn't get it to work.

At first I thought it was a duff SN76477 chip, as this is one I bought over 20 years ago and has been languishing in my garage for years. This proved to not be the case, as I've now got a couple more of these chips. But in this new drive of mine to get some modules finished, I found I had wired up one connector completely back to front. A bit of work with a pointed tool to release the pins, stretch a couple of wires then put them back in the right way round rewarded me with a working module.

Since I initially built this module, I've found that I don't like the Omeg pots I originally used, so will probably swap these out in the near future, but I'll play with the module for a while first and spend the time getting some more modules working instead.

That's one more module down, only another 41 to go.

Time for my first build of 2012 where the bulk of the components were bought in 2012.

This is an Oakley PSU2 +/- 15V PSU which uses a Yamaha PA-30 external power lump, which greatly simplifies the case building (No mains, earthing or transformers to worry about).

The cases are some neat 5U rack cases I found via eBay, here:

All Metal Parts on eBay

The 3U aluminium panels and 2U ventilated panels came from the same source.

If things go according to plan this year, I'm likely to use another 10 (5 pairs) of these cases to house the rest of my 5U modules, plus a couple of 6U cases for my Formant build.

On to my next module build now, to start filling out these cases.

Regards

Magman

210 One more completed module to add to my synth.

This time its a Juergen Haible Tau "Pipe" Phaser that I've had for a couple of years but I've finally got it working.

This module gave me a load of problems in recent days. After initial testing, I found a few pots I had reversed the wiring of. After fixing this and putting it back on test, Magic Smoke came out of the PSU of my main system (An R3 PSU from Farnell which appears to have piss-poor short circuit protection). Being totally pissed off, it was a couple of days before I got round to fixing the blown PSU (I finished one of my other PSU's instead, an Oakley PSU2, just in case).

When everything was back up and working, I found that it was this module that had gone faulty - with a short on the +15V rail. I had originally built this module with a couple of 10uF Tantalum caps on the PSU rails, so I immediately suspected these parts (one of the failure modes for Tantalum caps is unfortunately a dead short). Binning the Tantalum caps meant everything was hunky-dory again.

Incidentally, this version of the module has been built with SSM2210 transistor pairs. Given the Bridechamber currently sells these chips for $10 each, there are some $200 of these chips on this board alone. Not an inexpensive module.

Regards

Magman

My next pair of builds to be completed were a pair of Ryk M-185 sequencers. But I've already posted some pictures for these on the M-185 thread, here:

My latest module brings me pretty much up to date - this time an Oakley EFG (Envelope Follower/Gate)

I actually won the front panel for this at the UK Synth-DIY raffle in 2009, so it's been one of the longest duration builds in my work stack. It has actually been built for ages, I just needed to get round to testing it.

Working nicely now though.

Hi everyone!

Looks like the DIY community is off to a great start in 2012. Enjoy the looks and the sounds!

I just finished a CGS Infinite Melody and Diatonic Converter and managed to fit it onto a single-width (3x9") Aries-style panel.

Very interesting module, too -- it all came to life on the first power-up however took me awhile to calibrate the diatonic converter.
