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.

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.

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.
