Re: Re: Hmevision ir transmitter



2 errors actually.

The +5V to both the LED anode and cathode (via resistor)
and the HV output showing connected to ground.

I have sent you a drawing via your own email with your circuit and also
simulated it and it works now with the pullup on the input to the first
transistor.
