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.
Most of us have probably heard the old Tootsie Pop slogan, “How many licks does it take to get to the center of a Tootsie Pop?” [E-Smoker2014] had a similar question about his e-cigarettes. These devices are sometimes advertised with the number of puffs they are good for. [E-Smoker2014] had purchased an e-cigarette on a trip to Belgium that advertised 500 puffs. After a bit of use, he started to suspect that he wasn’t getting the advertised number of puffs in before the battery would die. Rather than just accept that the world may never know for sure, he decided to test it out himself.
There aren’t many details on this build, but you can tell what’s going on from the video below. [E-Smoke2014r] built a machine to artificially puff on an e-cigarette. The e-cigarette is hooked up to what appears to be vinyl tubing. This tubing then attaches to a T-splitter. One end of the splitter is hooked up to a DIY actuator valve that can open or close the port. The other end of the splitter is hooked up to more tubing, which in turn is attached to a plastic cylinder placed in a container of water.
To simulate breathing, the computer first opens the relief valve in the splitter. It then mechanically lowers the plastic container into the bowl of water, pushing out a bunch of air in the process. The valve closes, and the computer then raises the plastic container out of the water. This action creates suction that draws air in through the e-cigarette like a normal user would do with their lungs. The computer increases the puff count and then repeats the process, expelling any vapor out of the relief valve.
The results of the test indicated that [E-Smoker] could only get 59 puffs out of this particular e-cigarette before draining the battery. Not even close to the advertised 500 puffs. Maybe he should consider building his own e-cigarette vaporizer? Continue reading “How Many Puffs Does it Take To Kill an E-Cigarette?”
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.

This 3D printed scent distributor was put together by eight people from three states during the 2014 NYC NASA Space Apps Challenge. The team went on to take 1st place in the competition.
The project is called Senti8 and uses a FLORA Arduino micro-controller and a Neopixel LED strip purchased from Adafruit. A smartphone mobile app then remotely connects to the device allowing the user to choose which scent they would like to send to their friend, who is also wearing one of the wristbands.
They came up with the idea by simply asking an American astronaut named [Doug Wheelock] what he missed the most while travelling through the boundless reaches of outer space. To their surprise, he said that the thing he missed the most was his sense of smell.
Originally, the project was envisioned to be a wearable technology for space tourism. But over time, the project morphed into a wristband that would allow people to remember places or planets visited. Even memories unique to those places through scent could be experimented with.
One of the team members, [Brooks], was spotted wearing the Senti8 at the Wearable Tech LA conference in Pasadena, CA on July 17, 2014. The LED lights lining the outside could be seen all the way across the large auditorium as she chatted up with local Crashspace members as they prepared to present their design-oriented hacks to the public.
She gave an interview demoing the wristband which can be seen in the video posted below:

Electronic cigarettes are all the rage these days, and as with any new electronic bauble, someone is eventually going to stuff it in some old NES hardware. The NES controller e-cig has been done before, but [mastblast09]’s controller mod is one of the best ones around.
A bit of background before we dig into this: e-cigarettes are just any other *cough cough cough* vaporizer you might find, but instead of turning a solid into a vapor, these guys turn a nicotine-infused liquid into a vapor. As e-cigarettes are a bit more legal than some other magic boxes, there is, of course, an amazing amount of options out there for those that partake.
[Mastblast09] is using an off-the-shelf e-cig controller and charger board carefully placed them in a hollowed out NES controller. With the help of a few tact switches he made the B button on the controller light up the coil and the up and down switches change the wattage.
The real treat in this build is the addition of a very small LED voltmeter. With this, [mastblast09] can check out the voltage of his NES e-cigarette under load, a big help if you’re trying to perfect the perfect vape while the battery is under load.
