Vaporizer rebuild

vaporizer-rebuild

Wait! Don’t click away yet. Yes, this is a vaporizer project, but it has the distinction of being the most electronics engineering oriented post on the subject we’ve ever featured. [Mm Nn's] vaporizer broke so he decided to fix it. After poking around inside it became clear that pretty much everything was trashed. So this ended up being a complete rebuild of all the support circuitry, with the heating element being the only electrical component he could salvage.

He started looking around for a power supply capable of driving the element from the Arizer V-tower vaporizer. He hoped that he could use a computer PSU but ended up having to buy one to suit; a Mean Well rs-100-24. He drives the system with a microcontroller (programmed in assembly) using PWM to adjust the element. Speaking of, there is a sensor built into the heating element that [Mm] isn’t using because he couldn’t figure out how to read from it. If you’ve got some ideas let us know in the comments.

 

Mexican law enforcement seizes a hacked together Weed Cannon

marijuanna-cannon

Here’s an interesting hack. It’s a small pick-up truck with a Dope Cannon attached to it. Sure, it looks more like something you’d see in Syria, but this item was actually seized in Mexico where it was being used to fire 30 pound slugs of Marijuana over the border fence with the US. Usually when you fire artillery there isn’t someone on the target range trying to recover the projectile!

The device uses a PVC barrel to guide the pot-pellet as it’s propelled by compressed air. Hey, swap out the drugs for an energy drink and that sounds pretty familiar. Our qualifying entry for the 2012 Red Bull Creation Contest was an energy drink cannon which  used the same setup with a slightly smaller caliber. It makes us wonder if the drug cartel uses little parachutes like we did?

Doesn’t it arouse suspicion to drive something like this around town? You’d think they’d use a box truck or something similar to hide the giant gun.

How to make a vaporizer for smoking medical marijuana

Here’s a home made vaporizer we can really get behind.

Lets just take a second to be completely honest here. There’s no point in suggesting that this is possibly for smoking tobacco.  Medical marijuana is legal (well, not federally), in several states, and we’re sure there are hackers there that would really enjoy making something of their own instead of just buying something.

We’ve covered a few below and they always seemed to have something in common. They use soldering irons for heat. Inevitably someone points out what a bad idea this is.
