...on is that the smoothing capacitor has been removed, resulting in a 100 Hz signal going into the optocoupler (a pulse during each zero crossing). An interrupt is generated for each falling edge of the signal coming out of the optocoupler. This happens during the zero crossing, so tw

It appears the Altera chip drives two 245 chips which in turn drive the signal to the connector J1 to the LED board. * J1.1: IC2.A1 -> IC2.B1 -> via ... -> SRCLK signal of both column shift registers

...room antenna, to transmit a low-power GNSS signal that is a copy of a GNSS signal picked up on the roof. The signal is intended only for devices present in the room.

...t is still quite finicky and still not sensitive enough and needs a lot of signal to work properly.

* PWM, the laser tube intensity signal A low-pass filter is needed to average the PWM-signal before measuring it.

A signal that is reflected by an object in the view of the radar, will arrive back a Because of the delay, the outgoing signal will have already changed in frequency compared to the incoming reflected f
