KTRL CD32 Wireless (WIP)
I started working on a wireless version of my KTRL CD32 controller a few weeks ago. I had been looking into creating a wireless CD32 controller earlier but decided to design a wired one first.
So far, development has gone great and it has been a very interesting project. This is what I'm aiming for: CONTROLLER (The finished board has less wires, the nRF24L01 is soldered directly to the main board etc.)
The PCB design is "ready" but I have to wait a while before sending it to be fabricated, it might still need some change. Most of the functionality is there, I still need to implement the power save feature and radio channel select. RECEIVER
The PCB design / software of the receiver is mostly finished. However, radio channel select is not yet implemented. I aiming for selling PCBs (+preprogrammed Atmegas and components) so anybody with the necessary soldering skills can make these. I will make instructions for building these (including where to get parts) like I just did for the wired version here: http://www.daemonbite.com/ktrl/ktrl-cd32.html Here is a dodgy video of the controller in action: [ Show youtube player ] My work with this continues, please let me know if you have ideas or questions! |

Any idea what the cost is going to be on these?

The cheapest option would be to get the PCBs (controller+receiver boards) from me (at a reasonable but undecided cost) and the other parts from elsewhere (eBay, Mouser, Digikey). I will "finance" the development by selling boards.
Cost, if you source the parts yourself: (I will create proper instructions for this) Code:
Gamepad case: ~4€ Li-Po battery: ~5€ nRF24L01+ (x2): ~3€ Atmega328p (x2): ~4€ Other components: <10€ ---------------------- Total: ~25€ (+ the cost of the PCBs) I would love to be able to offer assembled controllers but I can't do everything manually like I did with the wired version, would need to find a better way. Others will be allowed to sell assembled controllers as long as they get the PCBs from me (since this is the way I'm financing the project). |

Would it be easily possible to mod the wired ones into these? And maybe you can offer "upgrade" kits?

Hmm, not that easy I'm afraid. The case, LED + wires and shoulder button PCBs can be used from the wired one, otherwise this is an entirely different design. I would of course offer upgrade kits if it was possible. Last edited by MickGyver; 05 September 2018 at 23:26. |

Mmm, too bad. Still considering though, makes sense for a living room Amiga CD32. But I guess they'll only come as kits as well, not pre-assembled. Could you give the dimensions of the receiver? The CD32 is sort of squeezed in in my TV cabinet.

After some more testing (playing some games), the communication is currently not very reliable at couch distance. I think I have counterfeit nRF24L01+ chips in my radio modules, this seems to be very common. I have now ordered modules from various places to see where I can get genuine chips and if reliability increases. I have been testing at 1Mb/s communication speed until now, that gives a latency of 600-700µs. I might need to go down to 250Kb/s to get a better range, this means that latency would be in the ballpark of 2ms, that is still low enough I guess, considering one frame at 50fps is 20ms. |

Project status
The scope of this project got out of hand but I should now have development under control. I decided to design receivers for other systems too. This is the current feature list:
General features
Controller
Receivers (for all receivers below)
Amiga CD32 Receiver (also for other Amigas)
C64 Receiver
MSX Receiver
USB Receiver

Very interesting! Been having terrible problem with CD32 controller (I bought the PS-controller adapter, but it doesn't work properly on all games), as I will never pay something like over 100€ for a controller for old machines xD
Maybe I one day make one of these... |
