Step 5Customize Away!
For version 1, I'm putting everything in a water bottle case. I'm undecided on whether or not the water bottle pop-open lid will turn the assembly on and off:) Not nearly as subtle or miniature as we can get with this, but it's a start.
If you're delivering a shock, run wires from the stun gun leads to the handlebars, stripping the insulation at points such that they're not touching the metal of the bike frame but will touch the skin of the bike thief so that they'll be in contact with a positive and a negative charge. The best way I've thought of to do this is to run the wires to the handlebars and wind both wires around both grips. I'd guesstimate you should use at least 22gauge and then anticipate them melting if used frequently.
Some suggestions for expansion:
-Vibrate only for a call / text message from a specific number
-Use on cars / motorcycles / scooters with an ignition kill as the payload(!)
-Add an accelerometer to control power to the cell phone
-Turn on auto-answer with DTMF to control multiple actions. Here's one such controller.
-Add a solenoid to trigger the brakes:)
Basically, go to town! And, if you're biking to town, be sure to disable your wacky security system.
Ohyeah, and this is remotely triggered onto anyone who comments telling me to put a shirt on in the video:)

@most everyone else - note the why would I care if someone got injured after stealing something of mine? If just one person did actually die from stealing a bike, word would spread quickly on the street and in the media, and there would be an instant reduction in bike thefts. I fail to see any problems with this. There are or were places where caught theives would lose fingers or a whole hand as punishment. If this was the case in these USA now, we would have next to no theft.
@liseman - Good idea on self-protection!
Finally, was the mountain public domain or did the climber get permission from the land-owner? If neither, then was the owner still at fault for the death of the climber? No. And if that climber is carrying my bike off up my mountain then I think I may cut off his rope and let him ride my bike down the cliff, or just shoot. once for a warning, twice for ignoring it.
As for those "places" where caught thieves lose finger, the US isn't one of those places. So, if you live in one of those places then you're good. If you live in the US - criminally and civilly liable.
Also, if someone who isn't even remotely connected with the theft is injured by you zapping the thief, as in the thief goes down in traffic precipitating a car crash that kills/injures someone, they you're on the hook for that as well.
Cheers.
Tally ho
30V is the maximum voltage that can be applied under worst case conditions (sweating, standing knee deep in salt water) and not reach 30mA. This is the standard for hospital grade electrical equipment (that's what that green dot on some plugs and electrical outputs signifies).

The stun gun is likely not lethal in its original configuration (electrodes less than 1 inch (2.5cm) apart) so there's little chance of driving a significant current through more than a few inches of skin, but increase the spacing and all bets are off.
F.Y.I.
Amps = ampere = current
Volt = voltage
Ohm = resistance
Amp = Volt / Ohm

It’s hot, but it's a dry heat.......
Watts ( W, a unit of power) = V * A (Volt * Amp)

AC terms (alternating current):
For resistive loads (incandescent lamp or heater), the same equation still works.
With reactive loads (motors), things are more complicated as the voltage and current are not in phase - they do not measure zero at the same time. Current usually lags behind the voltage (assumes voltage and current are both sine waves). Additional terms needed for this discussion include frequency, phase angle, true power, apparent power, reactive power, power factor, and complex impedance.
With harmonic loads (fluorescent lamps, most electronics, and lamp dimmers), current is either in phase with voltage, or is zero (current is not a sine wave, may be a pulse during each half cycle). Additional terms for this discussion include frequency, harmonic distortion, and crest factor.
More than you wanted to know?

For purposes of the stun gun, we can assume a resistive load across the electrodes.
pf = power factor.
power factor is only important to the utility company, not the end user.
