    Distortion Detector The purpose of this tool is to enable the installer to set the gain of an audio amplifier to match the source unit’s output level, accurately and quickly. It can also be useful for detecting distortion in the audio signal caused by poorly designed or malfunctioning audio equipment. Specifications The Distortion Detector’s circuitry is 100% analog Distortion Detection trigger level > 1.0% Harmonic Distortion Guaranteed operating range of input signal is 1.2Vrms – 125Vrms. (15,000 ...

    We are in the process of designing prototypes for our first product, which is similar in principle to a rechargeable battery pack. We are 4 Masters Engineers with a good technical knowledge but not the electrical know-how to design a circuit board. Therefore we are looking for some form of design assistance and consultancy service to help develop the PCB. This may be an iterative process and so some interaction would be desired, as well as production capacity. We have ...

    Hi, we need to Bluetooth/wifi module to connect our existing device (micro controller MC13213) thru RS232 port to read the log and update into server (using device id) automatically (auto synchronization) when Bluetooth or wifi available. Designer can use offself module (can't go new board design ) to fit our PCB and also need to take care of server side too (complete product). Please let me know if any questions. We have server already so we can give details ...

    I'm looking for someone to build me a camera board for a prototype. It needs to shoot hi-quality 720P/60fps video and 5MP stills at minimum and be compressed with some type of mainstream codec to be stored on an onboard SD card. I need to be able to control the camera functions- record on/off and when to capture stills with a microcontroller over some kind of UART most likely. Zoom and focus control is not part of ...
