Yeah mine is also veroboard, no PCBs. And I really have minimal amount, just some transistors / IGBTs to go form the GPIO pins to something that can drive bright LEDs and lamps.

Yeah it sounds nice, seems everyone is doing very similar things - WebSocket or Telnet to RPi or Arduino, the I2C to drive hardware.

BTW I recommend this board:

	https://www.abelectronics.co.uk/p/54/io-pi-plus <https://www.abelectronics.co.uk/p/54/io-pi-plus>

Which is stackable and gives 32 very easily interfaced GPIOs on a PI, over I2C. I’m finding that easier to deal with than lots of Arduinos, and the Pi can still drive an LCD to run remote-canvas on the HDMI socket. 

Kind regards,
