Em Theremin - Toko coil pins

Hello Everybody !

I'm a french student building the Em Theremin
After a lot of searchs I finally found and bought those toko coils (2x ez 1017 and 1x ez 1019) from jabdog

I was wondering about how to solder them in my stripboard... toko coils have 5 pins + 2 pins from the body http://imageshack.us/photo/my-images/535/p1050948o.jpg/

On the pdf they show : http://imageshack.us/photo/my-images/696/tokopins.jpg/
So the pins that interest me are the two which connect to the coil (correct me if i'm wrong..)

My question is : and for the others ? Pins are damn short ! May I bend or cut them ? Do I have to use some kind of pin "extension" ? If I solder the 2 two pins the coil will touch the breadboard, is it bad ?

You may cut the other three unconnected pins. In ever case you must connect the aluminum shield (the two large pins) to ground.

I suggest that you take a good experimental board with 0.1" (2,54mm) raster and no stripes (the EM circuit is too complex for stripes) but solder points, there will be no problem soldering all pins which gives more stability! :-)

Thanks ! I'ts all I wanted to know (for now..)

I already bought my experimental board, it has stripes... nothing is to complex for me B-) haha
I Thought a lot about choosing points or stripes..  finally I choose that way because... hem I don't know ! :) It's the first time I use breadboards, I'm happy with my board and I don't think that was too hard..  If ever I do another theremin I'll try one with solder points !

When there are lots of components closely co-located be prepared to make a lot of cuts in those board tracks. It helps to make a photocopy of the board and correctly lay out the parts in pencil diagram form first then work from that.

If you don't have the special cutting tool, a suitably-sized twist drill rubbed between your fingers will do the job, but be sure to check that you have cut the track completely in each case and watch for accidental solder runs/bridges.

.... but I note that you are well underway already.

Yes, I'm well underway ;-) but thank you anyway !

Sunday all the components will be welded, with my friend the multimeter I hope all goes well ...

I have one more question about the transformer, I didn't found any with 3 pins (2+ one for ground), do I have to pick one with 2 pins and add a ground wire ?

Yes!

Where do you get your transformer ? It seems easier to find the original Moog adapter (but more expensive, woah..) than a "simple" 12vac adapter that fit in Europe.. I wasted my entire day searching on manymanymany sites, the only ones I've found where from US, and I can't wait 2 weeks to receive them :S

And for the "with at least 200mA", 500mA will be ok ? And higher ?

I've found that beautiful one, with grounded plug !
