Canon X-07 is great little handheld retro computer. But being Canon, nothin is standard. Canon has always insisted using weird proprietary connector for devices, and usually it is impossible to find connectors that would fit them. This is also a case with X-07. It uses weird connectors for serial- and parallel ports. They look bit like a normal D-sub connector, and D-sub connector almost fits into them, but it is not a good fit. I wanted to make new connector that matches X-07’s serial port perfectly, so I took my callipers and 3D cad and started to work.
I soldered cable on contacts. Printed partes were not installed during soldering, and white acrylic pin holder did not melt like printed parts would have been. I also installed small strain relief rubber jacket over cable. Other end is just terminated with normal pin-header style connector, so that I can plug it into USB -> TTL serial port adapter. X-07 uses ~5V logic in the serial port, and it cannot be connected to normal RS232 port without level converter circuitry. There is also 4.6V output from batteries in one pin, that could power level converter, IR transmitter or maybe even bluetooth serial adapter. Connector also has software switchable 38,4kHz signal for infrared transmission modulation.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
