To connect the vape with an app :) I already have an app for the old prototype which shows battery state, temperature and PID settings. You can also see a graph for temperature and heating power in real-time. This is what makes the vaporizer quite unique and is what people find most interesting...

Hi everyone, I was busy since the last post :) I wrote parts of the wiki for the old version of my vaporizer. It should be easier to build, if you are interested. Also, I was experimenting with a nRF51822 module to get Bluetooth for the vaporizer. However, I am quite new to the whole ARM stuff...

Hi guys, sorry for leaving you waiting like that! I was very busy the last months and finally finished my degree. So more time for progress on the vape :) As mentioned before, I went open source on GitHub. Rebuilding it is very difficult right now, since the whole project is in a messy state...

I open-sourced it: https://github.com/acidg/vape_firmware_arduino Will add more information on how to build it the next days

Yes I did design it myself. It is the second version already, still had some minor mistakes in it, though.

The temperature sensor is used to measure the temperature, obviously :) It is placed directly in the airflow, so the air which hits the herbs is exactly the right temperature. The PCB is used to read the sensor's value and give power to the coil accordingly. I don't use 18650 because they are...

I did, however I don't think it's necessary. The wood gets barely hot, even after a long session and there are no signs of burnings. It's a PT100 temperature sensor (platinum) which is rated for +600°C. I think the holder is made of ceramic. While drawing on the unit, they won't glow. However...

Some more pictures of one of the older prototypes: Bottom cover removed. Here you can see the coils and temperature sensor, as well as the old messy PCB All parts separated CNC milled models of the latest version. The upper one is birch wood, the rest is teak View from the top during...

Hi all, thank you for your replies :) It's not a heated screen, but a coil of resistance wire underneath the screen which heats up the air when you draw. So it actually is convection. I am using a custom made PCB for controlling the heat using a mosfet, which is capable of delivering up to 120...

Hi all, because some friends and me were not that satisfied with the market of portable vaporizers, I decided to build my own. The main goals were as follows: Convection based - fast and high efficiency Made out of trustworthy materials (wood, glass, metal - no plastic in the heat path...
