Prototyping
From concept to prototype testing
  • PCB design and assembly
  • Circuit development
  • Dual Extruder 3D Printer
  • Wifi microcontroller interface

We love invention and technological creativity, and have countless project concepts in our head besides the handful presented here.

Many of our first hobby projects revolved around the idea of using a smartphone frontend to a microcontroller with wifi UDP as the datalink.


PROTOTYPING
Circuit Simulation
2015
  Circuit simulation of a soft power latch using EveryCircuit installed on a tablet. The circuit draws no power while turned off, and powers up when the push button is pressed momentarily. Another switch, controlled by a microcontroller, latches the power off.
SMD Prototyping
2015
  This circuit was drawn using conductive ink on paper with necessary components soldered where required. A momentary press of the ON button turns the circuit on, whilst the KILL button turns the circuit off.
3D Printer
2014
  We built our Felix 2.0 Dual Extruder 3D Printer from a kit and have made a few experimental enclosures and test prints. For intricate details we sometimes outsource our printing needs.

CIRCUIT BOARDS
C3DTOOL
2015
  This design combines the Intel Edison with the analog I/O from the previous prototypes to enable online python script development and execution.

CEDSCOPE Teensy
2014
  Based around the Teensy 3.0 and Gainspan module, this device was fitted within our first inhouse 3D printed enclosure.

C3DCOMPUTE
2014
  This prototype was a more compact version of the CEDSCOPE still based on the Teensy 3.0. This board also tests the power on/off function using the LTC2954.

CEDWIFILOG
2011
  Based on the Microchip PIC32, Gainspan module, and Sparkfun OpenLog, this prototype was designed to be connected to a GPS and Barometer breakout board to enable simple flight logging.

CEDSCOPE
2012
  This board uses an Atmel XMEGA to interface between the Gainspan module and analog I/O on the board. The circuit has two 5V input and output channels, and enumerates as a USB serial port using the onboard FTDI-serial chip.
