Build a Pizza Oven Out of a Weber Grill [DIY]
We've covered building your own pizza oven before, from nice and cheap to really cheap. But none of these were crowned Best Pizza Food Cart by vlog Ah Nom Nom; that title belongs to San Franciscan PizzaHacker and his modified Weber Grill.
Sure, PizzaHacker's pizza is delicious because it uses choice ingredients and a sourdough recipe to die for—but the other half of the equation is FrankenWeber, his modified Weber-grill-turned-mobile-pizza-oven. If you're looking for an easy, movable outdoor solution to your DIY pizza needs, this might be the way to go:
Part of what makes this open air culinary spectacle work is the heavily modded Webber 22.5" grill that's been outfitted with fireproof blocks and a domed top comprised of refactory cement and perlite that's been molded in the original Webber top. Using chunks of wood and charcoal, the Franken-Webber quickly reaches 1000F (the ideal temperature for cooking authentic Neopolitan-style pizza).

For a closer look at the FrankenWeber and its inner workings, check out the above video on Pizzahacker by Ah Nom Nom. There's no specific how-to for building it, but it shouldn't be difficult with the above materials and the close-up view in the video. If you've been hankering for some DIY pizza action but our past options just haven't done it for you, this might just be the solution.
Crank Up the Juice on a Cheap Laser Pointer [DIY]
If you're looking to have a little weekend science-lab fun with lasers it turns out that in the heart of every cheap laser pointer is a fire-starting, balloon-popping, monster.
What's the secret to upgrading your cheap laser from a boring presentation tool to a goggles-on-for-safety experiment? Over at Wired's How-To wiki they detail how to take apart a cheap laser pointer and find the adjustable variable-resistor on the circuit board inside. Tweak that resister with a small jeweler's screw driver and you can crank the juice up on your laser pointer—not too far or you'll burn it out! Visit the wiki at the link below for full instructions.
