Here’s a cool hack on how to make a physical gmail notifier.  You could probably use any other type of LED RGB device too.

I was given a lovely glowing cube by the generous people at Linden Labs as a freebie at a job fair yesterday, and I decided that it was far too attractive to simply sit there on a shelf, pulsating forlornly until its batteries went flat. How about making it useful, while maintaining its visual appeal?

Remember my post on how to make a DC Welder powered by a golf cart? Well, these guys must be golfers and must own a golf course. (or at least work at a golf course.)

Now, they figured out a way to power their batteries with a big solar panel on top of the golf cart. Now the question is, can you still drive the golf cart? This might actually be a lot more practical if they could make the golf cart solar powered.

These panels charge the cart at about 3 amps. Welding or driving draws up to 150 amps, but only in short bursts.
To my surprise I have to disconnect the panel after a day or two to keep from overcharging the pack. I probably only charge one day a week. I better add an inverter so I can power my office and other tools from this thing.

Warning:
This thing is so damn cool you’ll smile too much and hurt your face.
I probably should have put the cover back over the batteries before he started welding, cuz batteries can make hydrogen which can go pop.
You’re smart kids, you can figure out other safety warnings for this thing.

Here’s a hand crank shaver that you can charge by cranking it with your hand!

Awesome stuff. Now you can go green and make sure to keep your beard off.

As it is a wind up device, the battery s always going to be ready for that nice clean cut shave, with no hassle of charging through a power socket? With all the inconvenience that is involved with that, but at just $46 this shaver would appear to be very good value, and remember there is no need for batteries or charging.

Here’s a cool way you can make a DC welder powered by a golf cart!  Of course, you don’t have to use a golf cart but it is creative the way this guy did it.

Here’s the simplest welder you can make.
It’s just a pair of jumper cables and a welding rod.
Oh yeah. And some batteries to power it.
I happened to have some nice juicy batteries in the form of a Golf Cart.

Here’s me welding a trailer hitch with 1/8″ 6011 rods. Welding current peaks at around 140-150 amps with these rods and around 120 amps with 3/32 6013 rods according to a Fluke 1010 clamp probe.

Here’s a cool solar-powered sound system!

The sola-system’s parts were chosen in order to build a device that would be a one time buy. This means that after the original purchase the owner would not have to buy any other linked products (like batteries or adaptors) to use the speaker. This allows for much less waist economically and environmentally. The speaker system does not ever need new batteries, cords or disks, what you pay for is what you need.

Hi all,

This is a special review of giant green lasers on the market today.

Since I was getting tired of my little measly 125mW green laser from DragonLasers, I was going to go on shopping for a super-giagantic laser that will fulfill my dreams. (So I can burn stuff from miles away from my 12th floor apartment without getting caught…)

It’s about time that a mobile phone maker got their act together and finally designed a phone that could take an AAA battery even if it is only in an emergency, this would save so much hassle with batteries going flat etc.

The Philips Xenium NRG phone is already in production and will be able to use these normal or rechargeable batteries which can be picked up for a small amount of cash and no hassle.

The phone is due to be launched sometime in April 2008.

There is no doubt that there could be a huge market for these pots that do all of the work for you, and as gadgets should be created to make our lives a lot easier then that is the main point covered.

Obviously by using this there is no chance of burning off any calories, so maybe there should be a warning on the packaging somewhere. But really they should be thinking of a way that actually lifts the pot too!

Priced at $10.50
