I assembled the plates and my skate to visualize what I needed next. Adding some spacers alongside the pieces shouldn't be too much trouble, so everything aligns. The hardest part was keeping the bolts in line while I held the plates with my other hand.
Frame's test fit
I bought nylon spacers to bridge the gap between the plastic plates and square steel tubing to create rigid cross-members. I cut and cleaned the metal with an angle grinder and fastened everything with 1/4-20 bolts.
Motor and wheel bracket
My servo/ESC tester was missing, so I programmed an Arduino to accept button presses and output hobby-motor timing pulses. I tested with a small servo, but that was a problem since it wanted a wider time range.
Arduino screenshot
I put shrouded banana plugs on the load-side of my ESC and soldered the power side to a battery. It raised some alarms, but when I turned up the speed from my Arduino, the warnings stopped, then the motor spun. I have to correct the skewed timing I put in the program.
All system GO
I bought some spendy but powerful batteries for the project. Unfortunately, they didn't have the connector I wanted, so I cut the stock ones off, only to find that the style I ordered wouldn't fit the thick wire on my batteries and ESC. I ordered the correct ones, and I can test with these in the meantime.
Temporary connectors
After charging the batteries, I swapped out the temporary connectors and now have an XT60 adapter for my charger. I updated the Arduino sketch to recognize an analog joystick and took it for a test drive, but I need to do something about the unwanted speed bursts.
Look at it go
