Imagine he was in an accident and rendered unconscious with his car still powering the jamming device. Assume it was a single car accident, no need to be cruel to others. Anyhow, nobody can call for help and nobody thinks to switch off the ignition in his vehicle which is clearly not running. If it jammed first responders communication equipment too, all the better. He could enjoy a nice long wait for an ambulance.

Based on a steel mountain bike frame, it's decidedly INelegant and heavy, but super-effective on a commute that rarely exceeds 20 MPH by car.

I got a solid 7 years out of a 36V 10AH NiMH battery pack before it croaked. Now it is resting in the basement until I decide to re-power it with some flavor of lithium.

In the original post I asked if the Golden Island machinery motor was any good. Neither the motor nor the controller gave me a day's trouble though the original wire was too thin.

I also asked about lead-acid batteries. They were garbage. Too heavy and the power faded below a useful level long before they were considered discharged. I got a good deal on an NiMH pack and was very pleased with it overall.

I have since lashed up a 48V test pack and really enjoyed the power it gives. The original controller seems to work fine at 48V, the capacitors are all rated 60v.

The best thing I did was add a Watts-UP meter so I can keep an eye on remaining capacity and monitor power flow.

The most alarming thing about the bike is the brakes which are marginally adequate for the combined weight of bike and rider. They need to be upgraded before I hit the road again.

Frankly, I thought I'd never be able to play 4K video on my system.

Windows Media Player is completely unable to handle it and YouTube@4K is jerky at best, even with all the tweaks in Chrome turned on.

I am running a Radeon HD7700, Seiki SE50UY04 and a Core 2 Quad with Windows 7 x64 and the latest Catalyst and VLC.

Once I turned on hardware decoding in VLC it played flawlessly. I can stream YouTube videos to VLC but I can't get them to send 4K yet.

I used it to flatten out the hills 16 miles each way to and from work.

The best thing about it was passing the spandex-clad Harvard bike team while pedaling 20 mph uphill with my flannel shirt flapping in the breeze. Priceless...

The NiMH pack lasted until 2011. The bike is now offline until I can scrounge the money for a LiFePO4 pack.

Imagine coming up from a stone cold shutdown. What would be a super thing to have? How about DNS and DHCP? AD too if that's your thing. Some nice little box that can wake up your LAN in 5 minutes so you can start troubleshooting the boot storm as the rest of your VMs try to start up and all get stuck in the doorway like the Three Stooges.

Your program is sick! Shoot it and put it out of its memory.
