Step 4: Done!

I covered the finished circuit in hot-glue to protect it.
Hey Dan!  On which model of Sony are you using the remote control ?  Can you provide any other model numbers? 
I'm trying to use this for the same application you made it for, with the exception that I'm hooking it up to my ipod headphone jack, which only provides 1.1V. This is for a school project, but I'm totally illiterate when it comes to circuitry. What all would change if I used a transistor? What kind of transistor should I use? I tried searching on Digi-Key, but its all greek to me. I'll try to draw up a schematic of what I'm thinking of and maybe you could tell me if it might work?
any small NPN transistor should work to replace the NFET, and will let you use 1.1V input. eg: 2n2222 or 2n5088
Is there a way to turn the sony camera on using this system without needing the LANC?
Do you by any chance know the model number of a N-type FET that has a 1v threshold, I can't seem to find one through the listed sites?
it doesn't exist. the lowest that is made is 1.8V. however, a 1.8v fet wil probably be mostly on by 1v, so it might work for you.
Do you know what the model number is for the 1.8? Do they make it as a dual n/p like the one that you used above?
you can get PFET's down to 1.8v, i've only seen NFET's around 2.5V - which might work for this application, it is worth trying. you can get a dual N/P with 2.5V threshold. i haven't looked really hard for a 1.8V NFET so it might exist. try searching at www.irf.com or www.fairchildsemi.com, digikey and mouser then sell most of it if you find one. or use an NPN transistor instead of the NFET, since that will turn on at 0.6V.
Regarding the FET's Are the numbers in () the part#'s for digikey? Do you need to buy one chip or two? Why are they both the same part if the requirements are different? Q1: N-type FET with low threshold voltage (irf7309 or fds8958) Q2: P-type FET with low threshold voltage (irf7309 or fds8958) (Sorry I'm a bit of a newbie and just want to make sure I'm getting the right parts)
those parts have both an N and P in a single package. you will find them in digikey if you search for the part number.
