Unregulated simple all glass vape

Up and running off the same power source as the heater

That's all the actual components now need to figure out better housing and make some updates to code to enable the buttons and other minor updates.

curious if you have any estimates for power consumption?
so the PWM switching is all handled by the Pico board?
Was there existing code that you could make use of?
Nice job, this is fun to watch.

Not just estimates - real time power consumption now - there is a live volt reading and knowing the restance of the element it works it out live - quite cool to watch it adjust power in watts and not the arbitrary level of 0 to 10 for the pwm - there is now a temp/watt graph

so the PWM switching is all handled by the Pico board?

Yea all regulation is handled by the rp2040 - the actual power is controlled by a separate mosfet circuit - i wanted to keep this separate as it then allows the board to be used with solid state relays, normal relays and switched stuff.

Was there existing code that you could make use of?

I used some libraries for some hardware like the display, rotary dial and the simple pid library to do the maths.

Take a look at the repo on github its all available for people to use if they want - i have added some updates recently and will add more soon as i have already added some bits for the new leds.

Excellent job! congrats , Maybe i missed it but do you have the github link?


ooh ooh I want next hit!
