Raspberry Pi projects

Pi controller supervisor deveopments Control by VNC 1

Controller for four mains circuits using relays with provision for expansion by I2C, in particular remote temperature measurement for thermostat type functions. (Also see my port expander project)

Raspberry Pi running a Python Gui to control remote Arduino and similar controllers in the style of IOT. The touch screen has a Perspex surround which contains a proximity switch enabling the Pi to break out of a digital picture frame routine using an Adafruit Trinket to issue a keyboard esc character.

Power supply for the Pi with touch screen using recycled batteries from a broken laptop and a Sparkfun smart charging module. The unit works well with a BitScope oscilloscope module to make a reasonably priced test instrument.

Use of BitScope to analyse waveform fron piezo-electric sensor.

Use of BitScope to analyse output of TCL556 monostable circuit.

Pi Cam with Pan & Tilt

Camera with pan and tilt. Also includes an Adafruit Feather to do some of the donkey work.

Camera + pan/tilt

Greenhouse evironmental control 1.

Environmental monitoring & control

As in the project above (camera with pan and tilt) this project uses a Raspberry Pi and an Adafruit Feather in tandem to do the monitoring and control. Essentially the Feather does the basic monitoring and control and the Rpi monitors and controls the Feather. The whole system can be remotely controlled by VNC and UDP over WiFi.

Raspberry Pi case plus hard drive

Rpi case, includes hard drive & VESA mount.

3D-printed item to fit on the back of a monitor.

Raspberry Pi with Modules

Modular boxes for Pi extensions.

How the Raspberry Pi and boxes housing other circuitry can be locked together and split apart easily as required.
