Project Demo

One step closer…

ioio garage time

the olde clamp test

This thing screams with wall wart power. Watch…

Now comes the hard part…choosing a decent battery and mounting the circuit board savely on the chasis. I have found a few good candidates, but they are a little bulky for my application. Still looking…

The UI should be fairly straight forward. Just need a few more garage sessions, and I’ll be good to go.

The cordless Dremel was a super purchase FWIW. One of the best tools I’ve used.

Upgrading DC Motors to Servos

A whole bunch of Dremel work and some hot glue…

The Clocky conversion to servo motor control is mostly done.

getting close

I still need to make the servo mounts more secure, but the initial test runs look promising:

Getting close. I determined that the IOIO board will not fit inside the casing, so I will have to come up with an external mount. Which will change the balance, so I might end up having to add some counterweights for balance. It should shape up, mechanically, in another garage session or two. The UI work will be another session, thereafter, but look for a finished product within the next week or so.

RBG LED Controller

My off-the-cuff remark about building an auxiliary bilirubin light manifested itself into a quick project.

In order to approximate the specific color of the bilirubin lamp, I figured that I would need to provide a means of setting PWM values for the three inputs. I had hard-coded values in Arduino code in the past, so thought about taking that route initially. I blew the dust off my Duemillova, fired up the Arduino IDE, and promptly decided to modify my Java servo PWM code to do the job.

Sort of growing attached to the IOIO…sorry Arduino.

So, the controller was born…IOIORBG.
