Oil Truck Transforms Into Giant Mobile Grill

Oil-truck-transforms-into-mobile-grill

When the truck rolls up, everything seems normal enough. It’s a generic oil tanker. But when the theme from “2001: A Space Odyssey” begins to play and the side of the tank starts to open, you suddenly realize things are not what they seem. This is no mere tanker truck, it’s a massive meat cooking monster dubbed the “X Grill”.

[Ken Foster], owner and creator of this $40K+ beast, worked with welder [Gary Webb] to custom design and fabricate every component of the vehicle, from hinges to hydraulic systems. They claim not a single part came from a box. The cooking area, complete with speakers and spotlights, has storage cabinets, stainless steel prep counters, a four burner stove, and a 42 inch grill. If that’s not enough, there are three more grills you can set up beside the truck and hook into the system. All the appliances are run off a 65 gallon propane tank that’s mounted to the side of the truck.

Although the “X Grill” is available to rent for private parties, [Ken] says they spend most of their time at community and charitable events. He donates his equipment and cooking services, and the host group supplies the food and gets to keep any profit.

Good work guys!

Quick And Easy Rocket Stove

March 5, 2013 by Ryan Fitzpatrick 20 Comments

[Simon], a gardener in the United Kingdom, created this super cheap and easy to build rocket stove. The great thing about this little guy is that the methods and materials used to create it are so basic, anyone should be able to quickly make their own for just a few bucks. If nothing else, this is a good introductory project for people wanting to experiment with these stoves.

The only materials required are a metal 5 gallon cooking oil drum, a few scrap pieces of chimney liner pipe, and some sand. That’s it.

[Simon] cut off the top of the oil drum and made a hole in the front to fit the pipe. He then trimmed the scrap pieces of pipe to form a 90 degree elbow and positioned that in place inside the drum. Sand poured around the pipe acted as the insulator. Finally, he cut and flattened a scrap piece of pipe to use as a front loading tray for the wood.

Simple as that. Party on.

Sous Vadar

January 23, 2013 by Mike Szczys 22 Comments

[Craig] pulled off a beautiful build with his Sous Vader project. The name is a geeky spin on sous vide, a method of cooking foods in water held at a precise temperature. Building your own setup at home saves a ton of money, but it’s also a lot of fun. This explains the frequency with which we see these builds here at Hackaday.

So this one has a flashy name, a fine-looking case, but the beauty continues on the internals. [Craig] posted an image with the cover off of the control unit and it’s absolutely gorgeous inside. Part of the reason for this is the circuit board he spun for the project which hosts the ATmega328 and interfaces with the LCD, buttons, temperature sensor, and mains-switching triac. But most of the credit is due to his attention to detail. The image on the right shows him prototyping the hardware. Since some of his meals take 20 hours to prepare it’s no wonder he found an out-of-the-way closet in which to do the testing.

Make sure to read all the way to the bottom of the post for some cooking tips. For instance, since he doesn’t have a vacuum sealer he uses zipper bags — lowering them into water to push out the air as they are sealed.

Laminated Wooden Case Brings A Dropped Coffee Grinder Back From The Junk Heap

Instead of giving it up for dead, [Suprise Pink Mist] fabricated a replacement case for the motor and blade of his broken coffee grinder. The original enclosure was made of plastic, which didn’t survive being dropped. There isn’t an image of what those plastic parts looked like, but we have to think they were nowhere near as neat as the replacement.

The first step was to cut a set of plywood discs to the approximate outside dimensions. Since the base of the motor has several different diameters each disc had a void cut out of its center to match. The image to the right shows the motor sitting upside down next to the stacked plywood. The black electrical tape seals around the mason jar ring which was a perfect friction fit with the original bowl of the grinder. Once everything was glued together the outside edges were flattened on a belt sander and the mason jar was screwed in place to house the beans during grinding.

Kitchen Scale Key Transplant

January 14, 2013 by Mike Szczys 7 Comments

[Markus] is quite happy with his kitchen scale. It’s one of the tools he uses most frequently when cooking. But recently the button has begun to give him problems. He figures the years of spilling a little bit of this and that has mucked up the contacts. His solution was to bypass the button using a Cherry MX switch.

Really any replacement should do since the switch merely completes an electrical connection. But there’s a subset of hackers who swear by the Cherry MX switches that come in some keyboards. [Markus] had just such a keyboard on hand, which he was already using for parts, so he pulled out the switch and cut a hole in the scale’s case where he could mount it. After temporarily super gluing the switch in place he completed the task by filling the gap on the outside with hot glue, then running another bead of it along the inside. The addition of the ‘T’ key finishes the hack. The plastic key is easy to clean and will help shed flour, oil, or anything else he might spill during his culinary adventures.

This hack was fast and easy and may have convinced [Markus] to roll his own controller board for the device. We’ll keep a lookout for a follow-up post detailing those alterations.

Satellite Dish Solar Cooker Bakes Potatoes And More

Hone your survival skills by harnessing the sun’s rays to cook your meals. [Robert] and his daughter turned an old satellite dish into a solar cooker. The image above shows them baking some potatoes, but the temperatures inside the cast iron vessel are high enough to let you cook most foods.

The dish was originally used for satellite television but has been collecting dust in the shed for quite some time. When [Robert] came across a roll of foil tape in his workshop he decided to give the project a whirl. His daughter helped out by peeling away the tape backing (this can be much harder than it sounds) while he applied the reflective material trying to keep it free of wrinkles. After a close call [Robert] donned a pair of welding goggles when positioning the dish. If the light intensity can get the pot up as high as 428 degree Fahrenheit we’re sure it can cause flash blindness.

Unlike other dish cookers we’ve seen, [Robert] didn’t use the original mount for holding the dish in place. He just set it on three bricks and directed it by hand. To keep the intensity focused on the kettle he had to reposition it every 15 minutes.

We wonder if the heat is too much for building a sun tracking solar power harvester?
