Hi there :) The files I usually sahre are GERBERs (manufacturing files) and are not compatible with ESYEDA. You need the project files for that

Motors, Mechanics, and Power / Re: Problem loading code in ESC v3
« on: July 03, 2023, 08:16:06 AM »
The code has a small "ramp up" part where the motor rotates at the beginning withoput feedback jus to start its rotation. Then it passes to feedback loop. You should try changing the delay time of that ramp up part and maybe that will fix the starting issue.

That is very strange. Without testing I can't help you. I don't know the problem. Sorry!

It looks like the radio data is lost or unstable. Check the PPM pin or if the transmitter has enough power. Also, check the 3.3V of the radio module to be stable and not create noise

Maybe try burnning a bootloader first. The board is amde to work with the absic UNO/NANO bootloader with ther 16MHz clock so maybe that's why you can't uplaod. Also, amke sure the resonator is of 16Mhz and well soldered in palce. Also the DTR capacitor of 100nF and the pullop resistor on the reset pin. Those are needed for the uplaod

I don't think I'm the one whou could recommend you a good projector. I just make the teardown but I'm not ane experto of projectors... Sorry... Just watch a review online

No es tan sencillo. Si lo conectas directamente a la batería, ya no tienes la proteccion de corriente y de bajo voltaje. Por lo tanto el TP4056 solo sirve para cargar y parar la carga cuando se llega a 4.2V. Peor si la bateria se va gastando y baja por debajo de 2.7V o algo así, el TP4056 no puede apagar la salida ya que el boost está conectado directamente en la batería y no pasa por el TP4056.

Pero claro, el TP4056  solo puede controlar hasta 1A maximo. Así que las opciones que tienes:

1. En vez de usar una batería 1S de 3.7V, usar dos en serie de 7.4V y así la corriente es menor. Pero claro, el TP4056 ya no te sirve y necesitas un BMS de 2S diferente.
2. Encontrar un protector/cargador de batería con más de 1A de límite. L averdad es que es dificil de encontrar un módulo ya hecho con eso. Yo lo que hago es usar una combinación de buck converter + un BMS de 1S. Pero podrías probar de este link https://s.click.aliexpress.com/e/_DDrFoAh que parece un cargador con 3.1A de salida!
3. Solo usar un cargador sin protección como este https://s.click.aliexpress.com/e/_Dk1PTrr pero la batería se descargará al máximo y luego no se recupera si la dejas bajar de 2.7V

El boost lo conectas directamente a la batería o a la salida del TP4056? ya que el TP4056  tiene protección de salida de corriente y creo que es de máximo 1A. Por lo tanto si la tira usa 1.3A más las perdidas del boost, pues el TP4056 cierra la salida por seguridad.
Y si no es eso, no se si tu módulo de boost MT3608  está bien o si tiene agúna limitación de corriente. Debería dar más de 1.3A

Sensors / Re: How to read sensor voltage level accurately
« on: March 01, 2023, 10:33:11 AM »
DOn't really understand what is the problem. Make sure you use analogReference (INTERNAL); only when needed and when you use that function, the voltage refferance is not 5V anymore, is 1.1V from the internal voltage refferance. I can't understand what is hoind wrong with the rest because I don't know what you are actually trying to do... Sorry!

No se a que tutorial se refiere. Tengo 1000 :)))))

It might be that your motor has the wirtes wrong. Usually stepper motors have 1B 1A 2A 2B but sometimes they have them backwards or mixed like 1B 2B 1A 2A, 1B 1A 2B 2A, etc... so make sure the motor has the same input as the PCB. If is not that, we might need to check other parts... Also, try uploading just a motor control code before you test the full extruder code.

RF, Microwave, Ham Radio / Re: nrf24 scope problem solder on pcb
« on: November 21, 2022, 11:57:48 AM »
Hi. You shoudl try:
1. Place the 3.3V regulator close to the NRF24 and add a 10uF capacitor just at the 3.3V input.
2. Add ground plane to the PCB but NOT BELOW THE NRF24.
3. Place the NRF24 close to the edge of the PCBs o the antenna paret is on the outside.
4. Place the NRF24 far from switching parts (boost converters, PWM Mosfets, etc), since those create noise
5. Make the SPI connection tracks "as short as possibe" and a bit thicker >0.3mm so they conduce signals well
