Minigris test matrix demo
This demo shows that the mini grisbot (graphical robotic information system) test matrix has been successfully completed, with photocells and servos functioning and integrated. (And special thanks to Adafruit for the link yesterday.)

PC to Arduino to LED Control, Source Code
Due to popular demand, here is the source code for my blog entry, “PC to Arduino to LED Control.” First the Processing Source code: // ButtonProc // Make a button on the screen that can be clicked // and cause an LED to turn on and off in synch on // the Arduino. Used in conjunction with ButtonArd. // import processing.serial.*; Serial myPort; // Create object from Serial class int val; // … Continue reading
dual sensor test rig photos
That completes the hardware set-up for the dual sensor test. Now onto the software test phase. (Psst — the circuit has one glaring flaw, which I have since corrected. Can you spot it in the photos?)

Dual sensor test rig
This week I’ll be testing a new screen-reading protocol for Grisbot, involving two sensors. For that I’ll need a test rig. It will be contained in a box — Pop Tarts is the prime candidate — to be held up … Continue reading

Shortening Servo Wires (aka ‘Cables’)
My robot looked so nice in Sketchup, but that’s because I omitted the wiring. As you can see from the above photo, the servo wires just don’t fit even though I’ve trimmed them once already. I also had to solder … Continue reading

Grisbot to be laser-cut (a guided tour)
Finally, the Grisbot’s acrylic casing is being laser-cut, possibly even as we speak. Here is a guided tour in Sketchup of what may actually come to be by the end of this week, starting with the front view: The ruler … Continue reading

GRIS bot photos
Here she is, the integrated prototype. Note the cowling is fastened on the back and that the breadboard has just the ATMega328, not the whole entire Arduino board. An overhead view showing the arrangement of the servos, wheels, breadboard, and … Continue reading

GRIS bot circuit diagram
I’ve been working on this thing for months now, and it seems rather odd that only today did I think to make a circuit diagram. I think this is correct. I’ll get around to posting a photo soon too and … Continue reading
Mintduino Blink Test
Finished assembling Mintduino. The ATMEGA328 chip not only has the Arduino bootloader, it also has the LED blink sketch pre-installed, so when the battery was attached to the Mintduino, the Green LED started to blink. Tomorrow: attaching the FTDI cable … Continue reading
Assembling a Mintduino
I’ve been assembling a Mintduino, which is a breadboard version of an Arduino. The above photo shows me about midway through the process. The Mintduino case is a mint tin, hence the name. The case holds the electronic components shown … Continue reading
