I wired up my yellow critter with a control widget, a Turnigy 20A ESC and a 4.8v 2300mah nimh battery pack. Works quite well. I did have to add a relay to reverse the motor but that’s already supported by the software, it’s what I use in my RS3.

A pic from the video, out on the track at Gilbert Virginia.

Just can see the Xbee in the cab. The battery is in the engine compartment along with the Turnigy ESC. The relay to toggle the motor direction is also in the cab but you can’t see it from here.

The development platform for my Dash 9 whenever I get around to it. A close shot of the control board with the Xbee. This is the same control board in the Critter. There is just enough room (I think) in the critter to put in micro servos for the couplers but I have not gotten there yet…

And here is the critter with the handheld controller.

This is my newest critter design. A freelance sort of fantasy vehicle but it came out pretty good and was fun to build. A couple of 3D peoples and some resin cast details thrown in for good measure. Everything is cut out on the CNC machine except the fuel tank which is a piece of PVC pipe. (I cut those on the band saw). Anythow, I am planning on possibly selling these as kits or at least making the plans available, not sure how that’s going to work out quite yet…

One of my 3D printed 1/29 scale fellows on a CNC cut out Critter. Its a tiny locomotive I’ve designed based on a collage of prototypes from google searches. It’s cut out of sheet of 5mm finish ply and fits on a USA Trains 4 wheel power truck. I’ve left room for batteries and controls, I’m not a track power guy.

So this is the finished warehouse. Or I guess. It still needs some steps and other details but the main construction is done. I do hate that one support that is crooked. Hmm. Have to fix that. I need to light all of my structures and come up with a common power feed. It’s on the list.

Here are some pictures of my computer/manual switch throw. I was looking for a device that I could use to throw a switch both with a manual lever and also have a servo drive it for computer control. This is what I came up with. After a bit of testing, it seems like it will do just what I want. It uses a cheap waterproof servo, three magnets and a styrene throw. There are two magnets on the servo wheel and one on the throw. There is no connection between the servo wheel and the actuator other than the magnetic ‘clutch’. The ‘spring’ wire is a paper clip bent to fit. With the servo off or centered, you can throw the switch manually and it ‘clicks’ to one of the two magnets on the wheel. Under computer control, the servo can rotate to ‘pick up’ the magnet on the arm to throw the switch. Works quite well on the bench so I’ll be installing it soon to test out in Gilbert.
