Crazyman [Colin Furze] is back, and this time he’s setting everything on fire with his Pyro gloves. Though Hackaday readers are already a discerning bunch, this is a build we get submissions for all the time and feature fairly often. It would take an exceedingly impressive build to outshine the other fire hazards. But, as with his pneumatic Wolverine claws and his electromagnetic boots, [Furze] knows how to build the insane and then put on a good show.
The Pyro build is part of [Furze’s] 3-part celebratory X-Men extravaganza, a nod to the realm of superheroes coinciding with the release of the new X-Men film. [Furze] began with a custom reservoir cylinder that fitted with two solenoid valves: one for a pilot light and another for the big blasts. He’s also affixed a Piezo element and a AA battery, which sits in a cozy little container. The bulkier bits of the assembly sit in a backpack, hooking up, as expected, to the wrist-mounted devices. This flame cannon, however, is unique among the ones we’ve encountered here.

Everyone wants to be Iron Man these days, but without a spare arc reactor lying around, you’ll have to settle on building a backup suit component. [Xavier] documents his take on the wrist-mounted flamethrower in this dirt-cheap and unquestionably dangerous build. Cobbled together from parts found at a local hardware store, this glove has the typical “ready” setting with a small flame that, upon turning one’s wrist, erupts into a loud and large swath of flames. We suspect the mask worn in the video below doubles as identity protection and to prevent accidental hair conflagrations. Skip to the end for a demonstration.
Though not the first flamethrower build at Hackaday, [Xavier’s] is the only one with a guide and is certainly the cheapest. Be sure to look into the second generation of the Prometheus flame thrower and its subsequent third version that we featured a couple of years back. Not everyone’s flamethrower is wrist-mounted; some people put them inside a trombone. Remember, don’t try this at home.

It doesn’t look like much, but this easy to build propane forge is just what you need to try your hand at blacksmithing. [Code Cowboy] took on the build after watching this how-to video which shows the fabrication of a small knife after completing the forge build.
The first step is to eat all of the soup (or beans if you prefer). With an empty can in hand the stand — made of two angle brackets — and inlet are attached. Next comes the heat proofing for the walls of the forge. At first glance we thought that cat litter was one of the ingredients, but that’s just an empty container used to haul playground sand. The sand is mixed with equal parts of plaster of paris before adding water to achieve a clay-like consistency. This is packed into the can, with a small opening to receive the metal to be heated.
The torch itself can be used to cure the heat shield. After letting the mixture harden a 30 minute burn will force the rest of the water out of the heat proofing.

[MacGyver] [Lou Wozniak] is on a mission to build an internal combustion engine using only hardware store parts. What you see above is his third attempt at it. Depending on your hardware store this may have ventured outside of what they sell because [Lou] switched over to using gasoline. But the first two attempts were powered by a propane torch fuel canister.
Unfortunately it still isn’t running. But the demo below makes us think that he’s really close. Timing is always touchy and that seems to be what is causing the problems. He makes use of a lot of plumbing fixtures. At the right you can see the parts (including a peanut butter jar) which make his carburetor with a valve pointing straight up as the choke. The fuel and air mixture moves down through the pipe to the cylinder and valve assembly where it is ignited by the black grill igniter module. His custom cut plywood gear moves with the fly-wheel. It triggers his improvised spark plug by using a bit of wire to pull on the leaf switch.
We feel like he’s so close to getting this up and running. If you have any advice on where he might be going wrong [Lou] welcomes your input.

[Ralph Doncaster] has a geothermal heat pump which is responsible for providing heat for his home. He’s been looking into some hacks that would make it more efficient and decided that the freon (R-22) needed to be tweaked. Some would say the stuff is bad for the environment, so he decided to go a different route. He replaced the Freon with propane, using this rig to make the fuel-grade propane more like cooling-grade propane called r-290.
He purchased the gauge set which is used whenever a technician services an A/C system (but you can also see it in this other A/C propane hack). That’s important because it’s responsible for making sure the old coolant is recaptured (his hose failure nixed this part of the plan) and the new coolant goes where it should at the correct pressure. But before dumping in propane from the local hardware store he needs to dry it out. Fuel-grade propane can have moisture in it, which can be bad for the cooling system. He bought a drier device, the grey bulb seen above, and soldered it on one end to a propane torch fitting and to a valve connection on the other. Now he could remove moisture as he pressurized the system.
Everything is working again, and the cooling side of the system gets much colder. He plans to do more testing as time goes by.
A [Hank Drum], as explained here, is a steel drum-type instrument made out of a propane tank. The name comes from the [Hang] or [Hang Drum] which is significantly more expensive than that $40 or so an empty propane tank costs. Of course, you’ll have to do some work to get it to play beautiful music, which can be seen in a time-lapse construction video after the break.
The details of how this instrument was made can be found here, including how to lay everything out and cut out eight relatively neat “tongues” for producing different tones. I used a Dremel tool, but this can also be done using saber saw for a curved top. This method is explained here with a template, but the results may not be as neat.
If you want to try this yourself, make sure to use an empty, unused propane tank. This is extremely important. For another entirely different homemade instrument, why not check out the [Whamola] that we made a year or so ago? Continue reading “Making a Propane Tank Hank Drum”
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!
