Picture of Sonic Screwdriver 2.0

This more advanced sonic has improved sound! The previous sonic screwdriver had several disadvantages: The LED was weak, charging the 3.6v supercap took some finesse and various resistors, and the sound was provided by just a buzzer. Also, I kinda started charging it and forgot about it and the 9v battery busted my supercap. So, after breaking my original screwdriver, I started on making a better one. I took some suggestions from the comment field, and I have a 556 IC in Atari punk console circuit (Thanks to S. Cameron, I wasted a whole afternoon playing with that thing), a few new supercaps in series to make 5v, and a mini-USB port for charging (kudos to Drabinowitz).
I drew up a little schematic, and with some jiggery-pokery and a thin speaker in place of a buzzer it just fits. I also found some super-bright LEDs, and a red magic marker. Red is much cooler. Anyways, on with the building!

Step 1: The Stuff

There are a few disadvantages to the new design: The sound is a bit weak, and the bright LED only allows for around 5 minutes of continuous soniking with each charge. Also, be warned that supercaps are known to not hold a charge well, so don't expect it to work after leaving it lying around. 

That said, you will need:
As before,
a magic marker,
cheap pen,
Tirefly,
Push switch,
and a mini-usb port (mine broke so I went with the audio jack and rigged a custom charger).

The new stuff!
A pair of supercaps! these will be in series for a nice 5v, which is also what USB provides.
556 IC! Basically, it's a pair of conjoined 555's.
LED's! I found some cheap ones at that link.
An earbud speaker, or similar small noisy device.
Some capacitors and resistors; capacitors are 10, 0.1, and 0.01 uf. resistors will vary.

Tools
scissors, craft knife, pliers,superglue, a drill, and soldering stuff.

Also, do you have to use super capacitors? My class has everything BUT those.

I'm really confused as to how you put the punk console together. I get the concept of it, however I can't seem to figure out your execution in "shortening" the build by removing all the jumpers and such. Could somebody please help me with this? I'd love to do it for my electronics class.
Sorry if this question sounds dumb, but I am a novice at eletronics.

Basically the circuit is an Atari punk with the 100k and 51k. replacing the capacitors, is that correct?

Hello! Alskf1. I am looking at this design and really like it. What I did was put a uv light inside (stripped bare) and used that but I would like to try this for sound. For any price I would like to buy this soldered thing and some deep explaining on how to install it for any price including the push switch and jack.

So, Concluding from that ramble, I would like to buy The solder thing attached with the switch and jack.

P.S: Add a tut on how to make a custom charger too please.

Thanks!

Yours, JellyyFishh~!
Btw I have a soldering iron if you don't want to solder the push switch on

Hey This is a great idea ! Can You put sources for your push switch and tirefly and usb port and all the capacitors and resistors? I have found most of the things but i havent found some of the caps and res' and the tirefly and mini usb port

Is the main picture (a little more sonic) a reference to Jack Harkness's line "Who looks at a screwdriver and thinks, 'Ooh, this could be a little more sonic'?"

What power sources can I substitute for the supercaps? Would a simple rechargeable AAA work?

This is just brilliant!
