One of the more impressive presentations of a gadget at a recent Maker Fair was a floor-mounted four-hoop device with LEDs along each hoop. The hoops were circular in shape as though they were the longitude lines on a globe. When the contraption was rotated and the LEDs driven under computer-based control, a 3D display appeared. The resolution was visibly low but at inventor shows, it is more the idea that counts than its immediate refinement.
Over the next week I am asking our audience to suggest a worthy high school library anywhere in the US
The list of components that make up the iPhone 6S is similar to that of the iPhone 6 and 6 Plus, according to a teardown of a unit performed by engineering consultants Chipworks.
General decoupling applications require capacitors with a combination of high capacitance and low reactance (i.e., low equivalent series resistance [ESR] and equivalent series inductance [ESL]) in the circuit. The trend in digital applications for greater data throughput at higher speed is being met by lower voltage logic operating at increasing switching speeds.
Most differential field bus technologies, like CAN and RS485, specify a parameter called common-mode voltage. Common-mode voltage refers to the range of bus input voltages, with respect to the transceiverís ground, within which the transceiver maintains consistent input receiver thresholds.
