This little how-to was sent in by [Ed]. The sound dock posts get quite a few hits, so I figured I'd share.
There is a solderless way to hack an aux input for the Sounddock.
(1)Go to Wal-mart (or elsewhere) and buy the Griffin Dock Adapter for iPod Shuffle (~$20) and a Belkin Speaker and Headphone splitter (~$4). (The Belkin splitter is needed in order to fit properly over the Shuffle plug on the device, but other cables/adapters might work.)
(2)Remove the existing adapter plate and replace it with the Dock adapter.
(3) Set the switch to speaker. (Very Important!) (4)Plug in one end of the Belkin adapter and you are ready to go! Any input signal automatically activates the Sounddock. Now you have a fully functional female and male stereo headphone input for your Sounddock.
-->Total cost ~$25 and no soldering required.
Solderless aux in for Bose sound dock, etc

sorry `bout that.

3. i like soldering and both of my irons (13-30watt and a 10watt smd iron) is on 24/7 but nice hack
ps does anyone here have a good reliable flyback driver thats not transistor driven (i got 4 flybacks tody) also does anyone have a 555 driven soled state tesla coil (not flyback) scmattic

4. If you can't use any semiconductors to drive your flyback, the way to go is to set up a relay as an oscillator and drive it with that. You just put 12v (or whatever) to the common terminal, ground to one side of the coil, and the other side of the coil to the nc contact. Then wire the flyback from ground to the no contact (or the nc one, which ever works best), and pick pins at random from the bottom to find whichever one gives the best sparks. Or wind about 10 turns on the exposed part of the core and wire that into the relay.
As to the 555 driven tesla coil, it is possible to just send pin 3 from the 555 into a mid sized mosfet (irfp460 would probably work) in an open drain topology, and feed the primary with that. Of couse with a solid state coil you want nice tight coupling (ie, wind the primary directly on the secondary), and you will have to constantly tune the 555's frequiency to keep the coil in tune. Really, it is worth it to go to a self resonant or preferably pll based topology, but if all you want is a litttle plasma a fixed frequiency would work.
BTW, 4hv.org is a great place to ask questions about anything HV
5. Great hack on the sounddock with the Griffin shuffle adapter. Instead of the headset splitter, however, I used an 8mm female-female coupler adapter from Radio Shack with the Griffin adapter--about $4. Plus, I had to trim some of the plastic from the Griffin to make it fit tight.
Now I have an 8mm input plug without soldering a wire.
Works great, sounds great.

6. Can someone help me, I'm looking for someone who can build me a prototype of an ipod accessory similar tto the Nike-ipod but not as complex......let me know if you know someone who can...thanks!!....cbradley28@gmail.com

1. the bose sound doc sucks. as you turn up the volume it cuts out the bass and treble allowing it to get louder without distortion,but you only get the mids.
however the altec lansing m600 has a flat response curve at all volumes. sure it cant get as loud as the sound doc but it does sound better, and it has an aux jack built in, and its only half the cost.
