Between the marbled filament, debossed logo, properly countersunk screw holes, and rounded corners, it’s really hard to overstate how good this case looks. Fast forward to today, and his custom fan is a well-polished piece of kit that anyone with a soldering iron would be proud to have on their workbench.Ĭardboard has given way to a 3D printed enclosure that holds the fan, electronics, a pair of 18650 cells, and a easily replaceable filter. But as we all know, these little projects have a way of evolving over time. Prolific maker tells us the first iteration of his soldering fan was little more than some cardboard, electrical tape, and a hacked up USB cable. In the era of cheap 32-bit microcontrollers, it’s also refreshing to see hackers still dragging the ATtiny from time to time.Ĭontinue reading “DIY Fume Extractor With ATtiny13 Speed Control” → Posted in ATtiny Hacks, Tool Hacks Tagged 3D printed enclosure, attiny13, fume extractor, mosfet, pwm, TP4056 But projects like these are a great opportunity to practice your skills, whether it’s PCB design or creating bespoke 3D printed enclosures. There’s even a TP4056 charge controller to top off the internal 18650 cell when the fume extractor is connected to a USB power source. The first press of the button starts the motor off at max speed, but keep pushing it, and the motor’s speed will ramp down until it turns off entirely. But it still makes for a good starter project, especially if you go out of your way to really flex your maker muscles like did with this tidy build.Īll the hallmarks of modern hardware making are on display here - you’ve got the 3D printed enclosure, a motor salvaged from a cheap toy quadcopter, and a custom PCB which uses the ATtiny13 and an AO4406 MOSFET to implement a PWM speed control. Let’s be honest, commercially-available soldering fume extractors are cheap enough that you probably don’t need to build one yourself. We’re sure Kirby is quite pleased with his new role.Ĭontinue reading “Kirby Sucks, Literally” → Posted in 3d Printer hacks, Nintendo Hacks Tagged fume extractor, fume hood, fumes, game boy, HAL Laboratory, Kirby, nintendo, solder fume extractor Now, Kirby sits on his bench, and helps suck up all the bits and bobs of trash on his workbench. So he printed a couple more 3D parts so that Kirby could fit the end of his vacuum cleaner hose. ![]() He now had a more useful, practical fume extractor, but he couldn’t bring himself to discard his original Kirby. This design has the charcoal filter behind the fan, but he also has a third design for folks who prefer to have the filter at the front. And it can also be attached to the helping hand, making it a more utilitarian design. It has a flexible stand so it can be placed on a bench. ![]() So quickly designed a revised, no-frills model which is essentially a square housing to hold the fan and the filter. While Kirby served the purpose, it still didn’t meet the original requirement of attaching to a clip or arm on the helping hand. This allows Kirby to be tilted at the right position for optimum smoke extraction. The feet glue to an intermediate piece, which slides in a dove tail grove in the body. Arms and eyes are separate pieces that get glued to the body. The wires come out the back, and connect directly to a power supply barrel jack. The body has space for a 40 mm fan and a 10 mm charcoal filter in the front. The main body consists of two halves that screw together, and an outlet grill at the back. ![]() Getting from paper sketch to CAD model required quite an effort but the result was worth the trouble, and the design was quite faithful to the original character features. Several Kirby fan designs already existed, but none that satisfied. But somewhere along the way, the thought of a Kirby fan popped up in his head, and it was too good an idea to pass up. His initial idea was for a practical design more suited to his specific needs. Being unable to find an off-the-shelf product or a suitable 3d printed design that he liked, he built the Kirby 40mm Fume Extractor. What could serve him better would be a small extractor that could be attached to a clip or an arm on his helping hand accessory. ![]() This made his regular fume extractor bulky and inconvenient to position where needed. is not an electronics hobbyist and only does some occasional soldering. What’s common between one of the most legendary video game characters of all time and a fume extractor ? They both suck.
