Bus Pirate V2 Enclosure
This enclosure was modeled using OpenSCAD. The model is partially parametrized, meaning you can adapt the parameters given at the start of the file and an enclosure will be generated to fit your inner volume, holes, material thickness etc.
See www.thingiverse.com/thing:1716 for model source code.

Welcome in the club! Remember not to slack away the newly acquired freedom.
Note that in the 2010.01 release, extrusions from 2D to 3D are implemented (linear_extrude() and rotate_extrude()), as is the polygon() primitive.
Projections and planes intersections are still on the wishlist.

Energy meta meter mounted
Overview over the enhanced energy meter.
The JeeNode handling the radio transmission can be spotted in the lower left corner.
The yellow notes belongs to the old non-system of keeping track of power usage at the Metalab.

Energy meta meter mounted
This is the final configuration; meter circuit and cover clamped in place. The cable from the meter runs into a JeeNode which transmits the readings using an RFM12-based radio.

Energy meter cover and clamp
These are lasercut out of cardboard and delrin respectively. I used delrin since we had it lying around and it's a lot less brittle than acrylic. Cardboard is ubiquitous and cheap to laser.
The cardboard cover is used as a guide to align the sensor with the rotor disc and to block ambient light. The upper window allows humans to read the analog digits.

Energy meta meter "enclosure" 2
The capa enclosure has now set and become opaque white.

Energy meta meter "enclosure"
I used CAPA, aka. friendly plastic, aka. Polycaprolactone to make a quick and dirty enclosure for the meter circuit.
The capa is still warm and thus half transparent.
The slot in the middle is a guide for a clamp for attaching it to the energy meter.

Energy meta meter
Circuit for measuring revolutions of the rotor disk in energy meters, i.e. metering the meter. The detector is an EE-SY310 from Omron.

Arduino CNC controller
Closeup of our old Arduino CNC controller setup. The Arduino output signals corresponding to what the CNC software outputs on the PC parallel port. We then simple route these signals into a parallel port connector.

One of the reasons why the Linux desktop still isn't mainstream.
keyboard input method system? wtf?
