2022 Hackaday Prize: Disposable Vape Pens Turned Project Parts

Disposable vape pens, a sub-genre of electronic cigarettes, have been a fad for a few years now – they’re small self-contained devices with a rechargeable battery and some vape liquid inside. As the battery discharges and the liquid runs out, the entire vape pen is typically thrown out. [Dimitar] wants to change that, however, and teaches us how to reuse as much of the vape pen as possible – as yet another underappreciated source for parts we can use in our projects.

In an extensive intro worklog, he breaks down and documents a vape pen’s inner workings, coupled with a video we’ve placed below the break showing ways to disassemble them. In these, he shows how we can reuse the casing and the plastic parts, should any of us be interested in a project that happens to fit the e-cig form factor. Attention is paid to the sensor that triggers the evaporation – it may look like a microphone, but is actually a purpose-built pressure-sensor with a high-side switch! He tears into one of these in a separate video, showing how to reuse it as a capacitive touch controller. He also aiming to assemble a small database of related resources on GitHub, currently, hosting the files for the protection circuit he developed as part of his recommendations for safely reusing vape pen Li-ion batteries.

[Dimitar]’s journey is ongoing, and we can’t wait to see some fun uses for these components that he will certainly stumble upon on his way! For instance, here’s a hacker using an e-cig battery to power a pair of RGB LED-adorned sunglasses, replacing the AAAA battery they originally came with. We’ve seen hackers make guides on reusing each and every part of microwave ovens, printers and laptops, and we ourselves have talked about reusing ATX power supplies and computer mice.

Ghost Rider Costume Is Smoking Hot

It’s that spooky time of year once again, with pumpkins and cobwebs as far as the eye can see. This year, [Mikeasaurus] has put together something really special – a Ghost Rider costume with some amazing effects.

The costume starts with the skull mask, which started with a model from Thingiverse. Conveniently, the model was already set up to be 3D printed in separate pieces. [Mike] further modified the design by cutting out the middle to make it wearable. The mask was printed in low resolution and then assembled. [Mike] didn’t worry too much about making things perfect early on, as the final finish involved plenty of sanding and putty to get the surface just right. To complete the spooky look, the skull got a lick of ivory paint and a distressed finish with some diluted black acrylic.

With the visual components complete, [Mike] turned his attention to the effects. Light is courtesy of a series of self-blinking LEDs, fitted inside the mask to give the eye sockets a menacing orange glow. However, the pièce de résistance is the smoke effect, courtesy of a powerful e-cigarette device and an aquarium pump. At 225W, and filled with vegetable glycerine, this combination produces thick clouds of smoke which emanate from the back of the wearer’s jacket and within the skull itself. Truly stunning.

[Mike] reports that the costume is scary enough that he has been banned from answering the door as Ghost Rider. We think it’s bound to be a hit, regardless. For another epic mask build, check out the Borderlands Psycho. Video after the break. Continue reading “Ghost Rider Costume Is Smoking Hot”

Hackaday Prize Entry: An E-Juice Robot

E-cigarettes are increasingly popular, with weird hipster head shops popping up in towns around the globe. While you can buy this e-juice at gas stations and just about anywhere else analog cigarettes are sold, there are inevitably people who want to mix their own propylene glycol, glycerin, water, and nicotine. For them, [conklinnick] is building The End Of An Evil Industry, an e-juice printer that automates the entire process.

This ‘e-juice printer’ is designed to mix the basic ingredients of the consumables for e-cigarettes. These ingredients are propylene glycol and/or glycerin, water, flavorings, and nicotine. [conklinnick]’s project is using different ‘stations’ and a camera slider to dispense these ingredients into a small vial. It’s effectively a barbot dispensing ingredients for silly putty instead of alcohol.

It’s a great project, and although it’s not for everybody – nor should it be for everybody – it’s a great application of homebrew tech we already have for new uses.

Homemade E-Cigarette Vaporizer

Extensive research shows that tobacco kills. This is common knowledge as of late, which has prompted a flurry of anti-smoking ads to flood in. Regular smokers are now reconsidering their smoking patterns and are looking at healthier alternatives. Among those options are electronic cigarettes that vaporize flavorful liquid into smooth drags of smoke.

Prices for these devices can range anywhere from $40 to $240, which can be quite expensive for those on a budget. So instead of buying one, [MrRedBeard] decided to create his own DIY electronic cigarette contraption out of an Altoids can.

The approximate cost (not including batteries) is about $12. This covers the 5 Amp adjustable voltage regulator and the 500 ohm potentiometer that is best used for a rig like this. The wattage is what drives the heat giving it a more consistent vapor stream of cloud smoke.
