- hugs 11y agoI'm trying to drive the cost down to $1-2 per pin. It's obvious the MIT team did not optimize for cost. At $20/pin (from the SparkFun link), a 28-pin display (the minimum you'd need for a 4 digit, 7-segment display clock would cost $560. To so anything interesting, you'd want dozens or hundreds of pins. Cost is a huge reason keeping this idea from being more wide-spread.
- gene-h 11y agoWell if you really want to drive down the cost, the best thing to do would be to mass produce the actuators for the purpose. The actuators MIT used aren't really intended as actuators, they're some weird part for moving knobs around on high end audio equipment. Now as it turns out, there really are linear actuators that cost about $1 per actuator, they're just tiny: http://www.alibaba.com/product-detail/Goteck-1-5g-Super-Micro-Analog_60006747818.html http://www.alibaba.com/product-detail/Goteck-1-5g-Super-Micr...
