Re: Esc power safety switch?

Good to hear it worked .... On the simulator , it would not work with under 10V.
The cap is a good Idea , to stop and noise spikes from triggering the SCR.
R2 should also be reduced to 100R as 2K might be too high a resistance in the PPM signal path...

Re: Esc power safety switch?

I have found a problem with my design .... It wont work at 5V.
The 5V supply in not enough to trigger and get enough holding current flowing to latch the SCR.
Sorry about that ... :oops:

From a reliability point : I'll stand by my circuit ....3 transistors (2 are in SCR) will be more reliable than your Micro (thousands of transistors) and software which must execute.

Yes , once the scr is latched , you would need to remove the power, to reset it.

Re: Streamlining the Hobbyking OpenLRS Receiver

It would be easier just to cut the header off the board (leave enough pin to grab with pliers or tweezers)
Now just heat each pin and and use tweezers to remove.

Re: Ppm tester?

You could also use the PCs internal sound card for a simple scope

The key is to use a pair of resistors as a voltage divider , to scale the input so that you keep the Microphone input below 1V

Re: XR8 rx telemetary sensors

Have you thought about using a INA219 current / Voltage sensor?
This would add $2.50 to the cost , but allow for direct voltage measurement up to 26V
and with a current shunt you can measure the Amp draw from the battery.

Re: XJT Telemetry Module connection to Sky9x Rev3 Board

The color of the wires is not important

The 4 pin connector is upside down on your RF module , the two wires beside each other go to the RXD,TXD connections,
The one separated by the open pin (white) is the Ground , and should be at the bottom
