DEVLOG 3 - Upgraded electronics and wireless control on the engine.

Hello again everybody. For the past 10 days ive done major upgrades on the hardware an electrical parts . I bought a 433MHz RF Transmitter and Receiver Kit to make the controlling wireless , made a remote for the engine , put a thermoresistor that im having a bit trouble to translate to temperature , made a 2s battery pack for the remote and bought one of those mini gas canister to supply fuel.
I plan to put the thermoresistor near the nozzle to have a measurement of the exhaust gas temperature. About making the remote it was pretty easy , i got the casing from an old RC car and just put an arduino nano , 2s battery pack and the transmitter.
About the fuel supply it didnt have much pressure , s in the beginning of every run ill pre hear the car with some boiling water to get some more pressure.
To power everything up on the project i might use 2 battery packs , the main battery only for the ESC and EDF and another 2s pack for the arduino and eletronics in the engine.
Im still having trouble on the programming side and thats the only thing stopping me from the first test run with arduinos .
Also if anyone is curious about how this engine works and every special thing about it comment and ill make another devlog explaining everything you want to know.

DEVLOG 2 - Upgraded airfoils , inner design and some touches to the ESC

Hello. This time i better isolated the airflow inside the tube, because it had leaks and low pressure zones which made the flames leaked and could potentially go straight into the EDF and its powerful suction would make completely melt itself. Also removed the previous aluminium foil that was on the tube at the end , like at the exhaust to it would create a more tight space and therefore higher velocity gasses leaving from the nozzle creating more thrust. Then i noticed that the flame tube right behind the EDF was kind off not centered so i cut some nails in half and drilled some holes into the tube from outside to inside and put those nails in a way to center and hold the flame tube in position then just glued them in place from outside. Also tried to use a servo motor to move the slide potentiometer so i could throttle the fan speed as i liked . It can go from 20k rpm up to 110k rpm. at first it starts to work as i want but then just does spins and every time it does throttle it doesnt return anymore to its starting position its like it has lag , and its maybe the codes fault because i dont know programming i fully really on ai for this one. please if someone can help me comment and let me know , i really need help because im planning to use servos and arduino which is connected to a bluetooth module and then i will use to my phone to control it from a safe range and also make it look cooler. And also the last ting i want to say is stay tunned because this thing has a lot of thrust even without the flames so its going to be crazy and im going to make the first test after all of these big upgrades soon maybe in like 3 days because im not home. thank you everybody

FIRST DEVLOG- A entry to my project and the changes ive done when i got into stardance

I upgraded the fan from a normal hairdryer one to an 70mm EDF , its kind of ugly but ill make it work first then make it look good. Also fixed the flame tube and the fuel tube that had completely melted with the one ive shown and put the fuel tube inside of it where today i will also put the igniter on top (one of those cheap
voltage transformers).And for today tha will be it, on the upcoming days ill work on the arduino and servos to make everything controllable with a phone.
