Measure 9.5mm from the edge of the 1200 x 90 x 19mm pieces, then measure and mark as above. These points, however, are drilled as clearance holes. In the prototype, these were 5.5mm. Assemble the sides to the base with PVA glue between, referring to the diagrams, using the 35mm chipboard screws. Aug 5, 2019 - This project is a LED VU meter based on LM3916. Description LM3916 is a dedicated IC for VU LED meter. Unlike LM3915 which have 3dB step between voltage levels, the LM3916 have nonlinear steps: -20, -10, -7, -5, -3, -1, 0, +1, +2, +3db, just like old school analog VU meters. The specific VU meter uses a logarithmic scale of 3 dB/step, and gives a real view of the output power of the amplifier. It can be powered from a voltage between 10 and 13V, and can be connected to any amplifier having an output power between 1 and 200W. The VU meter is made from 20 rectangular LEDs.

Capacitors C4 and C5, proper wiring and correct PCB layout should help to maintain a good degree of noise immunity. For a stereo version of the VU meter the metering circuits shown here should be duplicated. The power supply has already been dimensioned for a stereo version ...Nov 02, 2018 · The resistor R2 must be twice the power of amp you are going to measure. To calibrate the device, Connect the output of the amplifier to port 1. Also, connect an AC voltmeter to port1. Set R1 fully off. That means full counter clockwise direction if wired conventionally. Adjust the output of the amp to read 20Volt rms on the voltmeter. flingster appseminole casino login L1a
