NaBo's been busy- My power supply and tb/fb loop box

[NaBo]

After coming home to the 40 odd populated circuit boards littering my bedroom, I made it a point to actually box some type of effect up and build a power supply before making anything else.

Finally, in between working/looking for a second job (ah, the joys of summer), and training Muddy (he's a ferret  ), I got the chance to complete a couple projects.

So without further ado, here's a pic of my (rather utilitarian) true bypass / feedback loop box thats in my layouts gallery, being powered by my dual 9V supply.



Here's some "the making of" photos that I'll just link to, in case anyone wants to see.  I did a fair bit of planning (more than usual anyway), so perhaps you may appreciate it:
The layout I came up with
Let's get started, little buddies!
Close-up of the regulator board (note the excessive thermal comp) and fuse delivery module
Top half fitting.  The cup o' Tim's to the left keeps me focussed.
Bottom half screwed in and fitting snugly
Wired up and raring to go!
Another view.  It only seems like too much wire.  When those transformers are on the bottom, it's just right
Lookin' good, pal!

Some of you may remember I had plans to make it a three-in-one supply, but then I decided that working with mains voltage isn't the ideal situation to do a cramped build.   :wink:

NABO!
Nice job!
How's going with the proximity control?
I'VE ALMOST DONE IT!!!!!!!!!!!!!!!!
It features a full voltage swing between 0.30V (no hands near the plate) and 5.62V (when you touch the plate) and it has got a sensitivity of about 20 cm.
It's impressive, cause it senses the hand even across the table: i put my hand under the table exactly under the plate, and I had the same voltage swing.
Now I put an inverting op-amp in order to achieve a reverse voltage swing (8.6V - 0V) in order to drive a FET: at the moment I'm using a 2N5485 and it worked fine. I linked the output of the circuit to the Gate and the resistance between Source and Drain varied from 0 to infinity; so I put a 1.8M resistor in parallel between S and D, and the resistance varied from 50k to 1.7M.

I'm so excited, I think that in I week I'll post the article in my site.

What about you?

Very cool NaBo, I like pictures.... will have to check out your layout gallery .......

hey Zero!

Cool that you got something working!  I haven't gotten any time to work on proximity stuff lately...  when I do get a spare moment, I'm working towards hard-wiring and boxing up some of the circuits I've already built...  sick of having to use alligator clips every time I wanna play with something!!!  

Good luck, can't wait to see it!
