There seems to be very little consensus on the arangement of the colours of the buttons on the back of K-9,
K9 has a 4 x 3 array of buttons on his back, I am using this image Binary kitten got me from the k9 at the Doctor Who Experience in cardiff as my guide for the lay out of the colours.
I am going to have to print the back for my Remote Controlled K9 in multiple parts, so for today’s Makevember post all I need is the 3D design finished and ready to print, and the schematic for wiring up the buttons finalised.
I am working on the assumption that only one button will need pressed at any one time, this allows me to simplifiy the wiring and only require one analouge pin on an Arduino to read the values in.
The Schematic software I am using is iCircuit,
It’s advanced simulation engine can handle both analog and digital circuits and features realtime always-on analysis. It is the perfect companion to students, hobbyists, and engineers.
Its a very basic application, however the application I am using it to replace was Crocodile Clips simulator, from around 2000. iCircuit could do with having a few more components, but it manages k9 Back Buttons fine.
I am going to need to make sure the measurments are right before I print it, and probably cut it into two so it will fit on my printer; however it is a second Makevember post.
