Brynn's "Tryclops" project
Laser modulator. This is a precision piece of electrical tape on the end of a DC motor. |
The "Tryclops" eye. A lens and a first surface mirror glued on PVC fittings. |
Brynn trying to focus on the modulated laser spot on the ceiling. |
The scope sees it. So he is detecting a laser spot about about 8 feet away. |
Alan's 125Mhz video detector with a laser focused on it. |
Brynn's 3-phase motor from a disk drive. This will spin the "eye" as shown in the diagram. |
Brynn sawed this on the bandsaw. He is finishing the cut with a Dremel tool. |
Brynn working on the "Tryclops". |
Brynn making another triangular mounting plate for his photo diode.
Bob's "Strawberry Robot" project
Jeff's engine/generator. |
Bob replacing the engine with an AC motor. (Much quieter and less smelly for testing.) |
Bob contemplating the next step. (Note the precision belt tensioner. A 2x4 wedged in-between the alternator and AC motor.) |
Bob's notes on alternators. |
Ron's "Aquarium Submarine" project
Ron's parts for his aquarium submarine. |
The CAD drawings he made from his "egg". |
The "egg" on the left shows his magnetic coupling. |
Drilling holes in a brass strip for the magnetic coupling. |
Ron is making an encoder disk from thin plastic on a dremel tool. |
Ron's collection of other small motors. |
Ron's original "swimming pool" submarine. This shows the small motor, an encoder disk, two optical encoders and a magnetic coupler. |
The "flipper" on the outside. It is magnetically coupled through the plastic. |
Someone takes these cad drawings pretty seriously. He is measuring off the drawing for the mill. |
A finished magnetic coupling. Magnets will be glued in the brass strips. |
Other stuff
Bob's Micro Mint boards. An X-10 interface on the left. An HCS-2 controller on the right. |
Bob's Micro Mint relay output board. |
Bob's book on PIC processors. It comes with CD and a blank board for a programmer. |
An HP7550 plotter we took apart. |
This is how I take the pictures. This is Brynn taking a picture of me taking a picture of the engine/alternator. |
I don't remember what Ron was talking about here... But everyone is captivated. He tends to do that when he talks. |
We're all looking at the HP7550 plotter we have torn apart.
