The-Cessna-172-Project-V3 Relay Trigger System Version 2 (Circuit Board)

Version 1:

[x] - [x] Change diode footprint
[x] Make "Port" Cables (30 pin oops)
[x] Rename EM1-EM14 MOS1-14 or OUT1-14
[x] Maybe just make this a 16 relay (14 with input 2 without) That takes up 30 pins?
[x] Maybe some should have analog input? Maybe some should be dimmer? (PWM and Analog enabled)
[ ] Circuit Breaker threads check
[ ] DFM Mini PCB check Circuit Breakers IDC
[ ] DFM Mini PCB silk screen backing
[x] Silk Screen Backing on Micro Switch
[x] Construct a G1000 Version Circuit Breaker and Normal
[x] BJT not a mosfet for my circuit breaker thing??
[x] Pop System needs to also have a few extra relay slots for aux things:
[x] Hobbs Meter YES STILL NEED, do resiliency testing?
[x] Avionics Fan - this is just literally going to be a switch :) you can override the avionics switch in the cockpit through fancy logic, outlined elsewhere

Let's use: 30N06L (Potentially use IRLZ44N)

Version 2:

[ ] Indicator LEDs in PARALLEL WITH BUTTONS (with 12V resistors)
[ ] Use a capacitor to smooth out voltage?
[ ] Use a capacitor to delay circuit breakers? (So that they don't all trigger at once) https://www.youtube.com/watch?app=desktop&v=iiwri9meO00

FAILSAFES (V2 will have these built in? V1 has them programmed):

[ ] Not all trigger at once -- NOT DESIGNED
[ ] Not trigger when power supply is applied -- NOT DESIGNED
[ ] Not trigger when power supply is lost -- NOT DESIGNED
[ ] Trigger for only a moment -- NOT DESIGNED
[ ] Make sure doesn't exceed 150mA limit -- NOT CALCULATED

It just requires a resistor and a transistor (They are driving the relay already). By choosing a NPN or a PNP type it works on High or Low signal. To let it only shoot out a short pulse it requres another resistor and a capacitor. That`s all. To drive the magnet, the same circuit scheme is required as if You would drive a relay from an arduino, So You will find thousands of examples in the web. one-shot (monostable) circuit. https://maker.pro/forums/threads/short-pulse-output.298294/
