This range of modules are suitable for use worldwide, running on the 2.4 GHz ISM band with FCC and R&TTE compliance. The same modules work both in NTSC and PAL video formats, and can transmit and receive wideband audio or video signals over a range up to 100m. The modules integrate audio/video input together with no external circuitry. They come with four selectable channels for video or stereo audio with output power up to 10 mW, 10 dBm compliant with European regulations. They measure 30.6 x 28.6 x 3.7 mm for the transmitter and 40.64 x 30.68 x 6 mm for the receiver, and have 55 and 140mA power consumption respectively from 5V supplies. They have an operating temperature of -10 to 60C, an operating frequency range from 2400 to 2483 MHz, and offer stable frequency selection with a four-channel, phase locked loop synthesizer. They cost $15.50 for the transmitter and $22.50 for the receiver.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
