ADAMnet Drive Emulator Mount

ADAMnet Drive Emulator Mount A while back, I posted a design for a 3D printed case for the awesome ADAMnet floppy drive emulator for the Coleco ADAM, designed to look like an ADAM floppy drive. More info can be found here: https://github.com/Kalidomra/AdamNet-Drive-Emulator. There is now a commercial version by the same author - find him on Facebook if you must go there. I thought I'd do another solution for the DIY'er who may not want a further external box, even if it's a cute little floppy drive, aww! As ADAM owners know, the computer supports two digital data drives but most have a blanking plate in place of the right-hand one. This solution is nice and easy, convenient, uses that blanking plate, and the mod is fully reversible. The Highlights: - Print out the face_plate.stl as oriented, with support. - Carefully remove the locking tabs holding the metal bracket to the blanking plate - Remove said metal bracket and the perspex window - Insert the display module into face_plate.stl - it should just snap in - Push the whole lot home in place of the perspex window - it should snap in to place - Replace the metal bracket and locking tabs - Print arduino_support.stl and clip your modded Arduino Mega to that - Take some double-ended female patch wires and connect the two devices (Sorry you can't plug the display and Arduino directly together, not enough room) -Fit the whole lot back into your ADAM, the blanking plate's screws will also serve to hold down arduino_support.stl -Done! Ok, ok, the Devil is in the detail: Apart from modding your Arduino Mega as per the ADAMnet github page, there are some other considerations: -Power -Communication -On/Off switch -Access to the buttons on the display module -Power / Activity LED Power: Power can be easily obtained from a spare power and GND on the arduino. Communication: I've included a space for a 7mm latching push on/off switch in the front panel, the latching bit is important and I'd strongly suggest getting one with at least 6 pins (three separate lines) as I'd recommend running the comms lines as well as the power line through it. Display module buttons: You'll notice they don't poke out of the front panel. Not being able to control the device could be considered to be something of an issue! The two solutions I'd suggest are: 1) Desolder the current tact switches and replace with longer ones - 6x6x12mm shroud do. Pro's: Nice, robust solution Con's: More fiddly soldering 2) Buy some little buttons to fit the holes to make up the gap. Pro's: Pretty buttons -Lower chance of breaking something Con's: Putting it all together will be an exercise in frustration - ...and again any time you want / need to take it apart - There's lots of choice on the likes of fleaBay but you'd be surprised how hard it is to get the measurements right. Power / Activity LED: The final hole is to allow a 3mm LED. This can be wired for Power, Activity, or both if you go for a multi-input (probably RGB) LED. Bonus Points: As the decals on the front panel are indented, you could fill them with a contrasting colour to help make them stand out. The mock-up ADAM parts (shell and bracket) are reasonably accurate so you may also find those useful for printing replacement parts. The Display shield mock-up is also reasonably accurate so could prove generally useful.
