Fig 4. Hands-on exposure to Open Labware in the developing world.

A, Each student assembled a spikerbox [10,49], an amplifier for neurophysiological experiments, from its off-the-shelf components. B, Students at a workshop in Dar es Salaam, Tanzania. C, The assembled amplifiers were subsequently used to perform simple neurophysiological experiments [51]. Image credit for panels B and C: Horst Schneider. D, One student set up a spikerbox via an Arduino to trigger closure of a “gripper-hand,” a low-cost robotic limb, through contractions of their forearm muscles.
