The synth is the photo-theremin from Electronics Goldmine. I'll try running it on 6v.

This is the guy: http://www.goldmine-elec-products.com/prodinfo.asp?number=C4164

Okay, the short story is I've got a squarewave synth, only sips at the 9v battery that powers it.

I'd really like to house it inside a bent delay that takes 6v. So, I'm assuming I need a 9v adapter, I'll get one at a full amp just to be safe, but I need to bring down the voltage after it powers the squarewave so it uses the same power adapter.

Help me, help me, help me. I'd prefer not to build a full circuit to make this happen, but I guess I can if it's really the best way. Is there a certain amount of resistance I can put before the power where it goes into the 6v device?

Still got 'em?

I still have the two S&Ms. Name your price, I ain't usin' 'em.

The SK-1 is not bent.

I've got a Realistic Reverb with two bends. I've got a Barbie Karaoke tape deck unbent. I've got some other things that are escaping me right now. What are you looking for?

I need this out of my house.

Also a couple Speak&Maths, a VTech Music Major, a bent Musini, a couple unbent Musinis, other music gear.


Make offer. Seriously need this stuff gone.

I feel REALLY left out. I don't have any!

Seconded. You can even get one of those 120vac to 12vdc converters that you plug into the wall

Like this!

Highly doubtful, the same chip makes all the letter sounds.

Maybe find 26 identical abc toys and put them all with their own outputs into a huge box?

You can take the wires running to the speaker and use them for your line out jack, or you can use new wires to connect your jack to the speaker, to use both.

Just connect one side of the speaker to the ground tab, and the other side of the speaker to the other tab of the jack.

If that is too hard to understand, I can draw you a picture.

I don't think you can get sounds by plugging your guitar straight in, but you can get sounds by plugging the reverb tank into an amp and manipulate the springs.

It depends on what your circuit is supposed to do... most of the time, continuity testing is only good for checking the actual traces, any components will alter the path and not give actual continuity. If you've got a broken resistor, etc. then you might not get any signal flow at all.

What does the circuit do?

On a side note, is the aforementioned book the best one to get? Can anyone recommend some good circuit bending books?

Thanks

P.s Where in europe did you get this book? I can only see it coming from US

Also look for "Handmade Electronic Music" by Nic Collins.

I got one of these and they're sweet.

So far:

1 - I've soldered a bridge over the wetness limiting resistor.
2 - installed a 470k pot over the delay time.
2 - (like rjl suggested) I've soldered in a "safety" switch replacing the feedback limiting resistor. This switch goes between a straight wire bridge and a wire with a series of resistors (8.9kohm*) - this flips the feedback knob (set at max) to either true maximum or a value just before true feedback starts.

CAN you tell me or show me (total novice) how to fit the saftey switch? a photo would be very good. have done the first two mods but would like the option to calm it down

What do you mean? Are you looking for somewhere to put the switch? I used the space in the battery bay for the mod components [I use adapters].

Ah - thanks a lot! I'll go try that now. I don't have any 250k pots lying around - just a spare 1M and a couple 1k's. Should the 1M work fine to test it?

EDIT; Ok, I just wired it up with that setup. It only passes the signal when the momentary "record" switch is held down.

I'm also guessing a 1M pot isn't suitable, as it's still REALLY loud and distorted. I can't even tell which way is turning the volume down. :naja:

Is this normal and just the quirk of this looper, or did I do something wrong?

I don't think you wired the output volume pot correctly... maybe it's my drawing, maybe not, but something is not sounding right.
