IMPORTANT: When assembling, make sure the wires don’t press on the Nano reset button on the board!! That happened to me on one and threw me for a needless loop! More wires in there now though, so it makes that much more important to keep things tidy when routing the wires. I added the 7 wires for the radio chip to the nRF24L01 (5 comm wires, 3v and GND), then connected the other ends to the Nano. It does involve going back in, but I was able to undo the existing connections to the Nano and then reconnect to the appropriate pins without too much grief. Now, I’ve done this change a few times and it turns out that the process isn’t too bad. To those who have already built the previous model and want to make a “Radio Turret”. After looking into this for a bit, I realized which connections took priority, and recognized that to make this work, I would have to remap most of the existing Nano connections. I needed to add 5 connections to the Nano, and I was already low on available pins. Just don’t include the nRF24L01 radio chip.

It won’t make a difference if someone wants to build the non-radio variant. I just deleted the non-radio option from the printed parts in that build. The modified chip holder is already part of the turret printed parts now. One physical part modified, with some wiring. I just modified the chip holder to include the nRF24L01, the Nano and the mp3 chip. Hmm, adding the physical PCB into the turret was pretty easy. Once that was done, it was a matter of incorporating the radio into the existing turrets. I first got the radio working with a few bare Nanos, to make sure I could send information between multiple devices. Step 1: Incorporating the Radio Into the Turrets I also wanted this MTC to be wireless, so I opted for a simple 9V battery powered option and designed the controller to be powered by the mini-USB plug through the Nano at the back. Sounds good! Simple enough…Ĭhat : I recently saw the “Who’s on First” - Abbott and Costello routine again, and a light went off in my head! I would also make a sketch comedy routine using all of the sayings, using multiple turrets!! Ok, this one wasn’t fully figured out, but I’m sure I would get it sorted once my build was underway. Push button 1 would fire the turret, and maybe push button 2 would make it say one of its sayings. 2 axes = a joystick, so joystick control and some push buttons.

Manual control : So once the wings are open, I would like to control the pitch and the pivot. Cara Mia was already on the agenda, but what else?

I would have to build a controller and started mulling over what the controller would contain and what exactly I could do to the turrets.

I had some nRF24L01 radio chips which I hadn't yet used, and thought that would keep in line with my goal of using inexpensive components and relying on mechanical design and code to make this work.

Ok, so how to go about this? Well, I didn’t feel like modifying the turrets too much, so that was a constraint. After giving it some thought, and thinking that manual control would also be cool, I ended up deciding that I would build a Master Turret Controller, or an MTC. I can do that!” Well, I had the turrets, but to make it work, they would now need to communicate with each other, or with some other device. I thought, “hey, I’ve built a few turrets now. The LCD screen is particularly useful when customizing.Īfter I had completed the Portal Turret, I saw a short video clip of the Cara Mia opera scene at the end of Portal 2. It can also be used as a cheap controller to control anything that uses the nRF24L01 radio chip.

This project is an extension or remix of my original Portal Turret ( Portal-2-Turret-Gun ).
