If you search the web, you will learn that humans began to cook their food with fire a long time ago. Indeed, you might expect that there would be nothing new in the world of flame-based cookery. Fortunately [Bongodrummer] didn’t get that particular memo, because he’s created a rather unusual rocket stove griddle that is capable of cooking a significant quantity of food.
A rocket stove is designed to achieve as efficient use of energy as possible by achieving the most complete burn of high surface area fuel. It features a small combustion area and a chimney with supplementary air feed to ensure that exhaust gasses also burn. This one feeds all those hot gasses directly to the griddle, before taking them away up a pair of flues. As an added bonus there is a dome attachment for a pizza oven, made when a previous project had some left-over building material. Take a look at the comprehensive build video below the break.
Perhaps alarmingly the combustion chamber and chimney are made from a gas cylinder, but the use of a central heating radiator for the griddle is an extremely good idea. A vortex air inlet at the bottom and a secondary air injector further up the chimney complete the unit, making for a worthy replacement for a traditional barbecue.
It’s worth saying, this isn’t the first rocket stove we’ve seen, there was this simple design as well as this very well engineered space heater.

[Strn] and his friends love to barbecue no matter what it’s like outside. But something always seems to interrupt the fun: either it’s time to get up and turn the meat, or the music stops because somebody’s phone ran out of juice, or darkness falls and there aren’t enough flashlights or charged-up phones. He had the idea to build the Swiss Army knife of barbecues, a portable powerhouse that solves all of these problems and more (translated).
Most importantly, the E-Mangal rotates the skewers for even cooking. It does this with a 3D-printed worm gear system driven by the heater flap actuator from a car. After 25 minutes of slow rotation, a voice announces that it’s time to eat. [Strn] and friends will never hurt for music options between the pre-loaded tracks, Bluetooth audio, FM antenna, USB, and SD options running through a 3W amp. Two USB lights illuminate nighttime barbecuing, and the 10 Ah battery can do it all and keep everyone’s phone charged. For safety’s sake, [Strn] included a half-liter water tank to extinguish the coals via jet stream. Everything is run by a PIC18F, and it can be controlled at the box or through a simple web interface.
We love the look of this barbecue controller almost as much as the functionality. The sturdy stance of those short, angled legs give it a mid-century appliance feel, and seeing all the guts on display is always a plus. Grab a turkey leg and take the tour after the break.
The E-Mangal has a thermocouple in the coal box to measure the temperature, but there’s no direct control. If you’re more interested in temperature options than entertainment, here’s a project that micromanages everything on the grill.

We’re not actually sure that it’s a good idea at all, but it’s got a heck of a lot of style; [Morgan]’s barbecue grill is turbocharged. Literally.
Keeping with the automotive theme, a serve-motor-driven throttle from a Ford Mustang serves as a (naturally-aspirated) air intake, and a Honda Civic manifold delivers it to the grill. But when he really needs to turn up the heat, a 360 watt fan can force-feed the fire.
