Bristlebot: A tiny directional vibrobot. The BristleBot is a simple and tiny robot with an agenda. The ingredients? One toothbrush, a battery, and a pager motor. The result? Serious fun. (YouTube video here.) The BristleBot is our take on the popular vibrobot, a simple category of robot that is controlled by a single vibrating (eccentric) motor. The starting point is of course the toothbrush. Cut off the handle of the toothbrush, leaving only a neat little robotics platform. Next, we need a vibrating pager motor or other tiny motor with an unbalanced output shaft. The kind that I got are happy to run on almost any common voltage– probably a range of 1-9 V. The last substantial ingredient is some foam tape. Attach the motor to the foam tape. A better method is to bend one of the leads down flush with the foam tape, so that you can *stick* the battery to the foam tape as well and still make an electrical connection.

Abstract NIR spectroscopy is used routinely for the compositional, functional and sensory analysis of food ingredients, process intermediates and final products. The major advantage of NIR is that usually no sample preparation is necessary, hence the analysis is very simple and very fast (between 15 and 90 s) and can be carried out on-line. One of the strengths of NIR technology is that it allows several constituents to be measured concurrently. In addition, for each fundamental vibration there exists a corresponding series of overtone and combination bands with each successive overtone band approximately an order of magnitude less intense than the preceding one. The major limitation of NIR spectroscopy in food analysis is its dependence on less-precise reference methods.
