The Voice is a bit simpler and offers "an open-source VOICE RECOGNITION platform consisting of a 3.14-inches in diameter dev board with a radial array of 7 MEMS microphones connected to a Xilinx Spartan6 FPGA & 64 Mbit SDRAM with 18 RGBW LED's & 64 GPIO pins".
Subjects were blindfolded and sat on the flat side of a wobble board (board diameter: 43 cm, diameter hemisphere: 10 cm, height hemisphere: 5 cm).
Each intervention team was provided with an instruction booklet, eight balance boards (disc diameter 35 cm; Fysioline, Tampere, Finland), eight balance pads (50×41×6 cm; Alcan Airex, Sins, Switzerland), eight medicine balls (ball diameter 28 cm, weight 1 kg, Togu Gebr Obermaier, Prien-Bachham, Germany), and an exercise diary.
We are constructing a TPG read-out module with three GEM foils (30 cm diameter) and a read-out board (30 cm diameter active surface) covered with hexagonal pads of 300 μm size.
On board, a 12cm- 5 inch-) diameter disc embossed with one hundred pictures representing our civilisation – images of human endeavour, innovation, culture and cruelty; pictures of the natural world and the changes we have brought to it.
A piece of food (1/16 piece of commercial dog food for crows and 1/8 for ravens) was hidden below one of two red cups (1 cm high, diameter 4 cm) on a blue board (50 cm × 20 cm).
Regulation hoops are ten feet high and 18 inches (45.7 cm) in diameter, typically backed with a plexiglass board off which players may bounce shots.
Take the fireboard and mark a spot about 1.5 times the drill's diameter from one of the fire board's long edges.
Cups measured 6 cm in diameter and 6 cm in height, boards measured 13 × 13 cm.
During the recordings the rat was able to freely move in a brown paste-board cylinder (70 cm diameter, 50 cm height) that was highly familiar to the rat due to previous EEG recordings.
The designed board is a 60 mm diameter, 0.6 mm thick circular FR4 board that weighs approximately 5 g.
