I am sure many of you encounter situations where your nuts or bolts stay on the rim, causing you to accidently break it off.  Now, if you ever get those hard-to-remove nuts whether from rust or whatnot, you can use this method of heating wax with propane gas near the nuts and bolts to get them totally loosened.

I’ve personally broken a rim stud before, and needless to say, I wish I had known how to do this back then.

I have a trick that has been around for a long time. This is a trick we used to use for exhaust manifolds when the bolts were so rusted in that breaking a bolt was very likely to happen. To avoid having to remove the stud in a separate process we used this trick to get them loose. This works better with a fair amount of heat to start and then let the wax slowly cool for about 3-4 minutes before attempting to remove the bolt of nut.

You know when it comes to New Years and Independence Day, you always get to see some really exotic, beautiful fireworks.  Well, all those fireworks are nowdays controlled by an ignition control system but here’s how to make one for yourself.

At the heart of my firework ignition system is an SX48 running at 50 MHz. I was able to make full use of the SX’s 36 IO pins. Thirty lines are dedicated to the 30 channels. Two lines connect to a MAX233 chip for serial port control. Another line is connected to a 7805 (TO-92) which monitors the state of the arming key. The remaining 3 lines are used to communicate with the PIC A/D converter via an SPI interface. The system was built with cost as an important factor. At $10 the SX48 Proto board was an easy choice with its incorporated 5V regulator, led and all the difficult surface mount soldering already done for me. I also designed 2 pc boards using the freeware version of Cadsoft’s Eagle. The interface board connects the SX48 Proto board and contains the MAX233 chip, A/D converter and 30 LEDs to represent the state of each of the 30 channels.

Here’s a video of how to make a ghetto flame thrower using your jacked-up lighter and some spray cans.

Now, don’t go out there and burn off your dog, that is very BAD BAD BAD.

Here’s a cool DIY Flame Thrower project that will remind you of X-men characters.

Definitely this isn’t as powerful as anything in the movies but will burn most things off pretty fast.

The Pyro System is my final project for a mechanisms class in the spring of 2008. It gives me the power that the X-Men character Pyro has

If you are heading out to the mountains to camp out for couple days, you might want to consider getting one of these Wilderness Survival Fire Sparkle and Blade Cutter which can start fire with ease.

Of course you can always carry a bunch of lighters with you but where would all the fun go then?

Re-live the wilderness at only $5.90.

Believe it or not, this guy claims that he can start BBQ charcoals faster with his homemade wire-mesh and hair dryer.

You might want to consider trying this method for your Independence Weekend BBQ.

Whenever I have trouble starting coals for my BBQ I grab a hair dryer, point it at my grill and pull the trigger. One minute later I have red hot coals and I never have to use any lighter fluid to get them started.

Video after the jump!

Here’s an interesting photography hacking tool.  Basically the image fulgurator inserts messages onto other people’s photos by displaying the letters at the exact moment the innocent photographer’s flash goes off.

Kind cool for sending messages in a tourist attaction.

It’s a reactive flash image-projector… or, to put it another way, a real-world hack of other people’s photos. Sounds sinister, looks sinister… works great. Adapted from a flash gun and an old SLR, it senses the flash of someone’s camera, and then quickly illuminates itself, projecting images or text onto the object that was being snapped. The video of bemused tourists in Berlin, peering in confusion at the screen of their digicams is priceless.
