I need to install 5.1 surround sound system in the carpeted basement. I have amplifier and also the required cables but may need you to advise what else I may need before someone comes over to install it actually. Everything I have is 16-18 years old. I need to instal over the weekend of 27-28 Aug preferably. Thanks. I would say the area is 5 .5 meters X 6-7 meters. I don’t need to conceal wires inside the walls but externally instead as I plan to move in couple of years.

I need a simple audio hardware design/schematic to manage 8 zones of already wired left/right speakers in my home and two out by the pool. I think I would like a page on my iPad and iPhone which gives me all options of what music I wish to stream, (only one stream for all 8 zones at a time). Off/on for each zone, and volume. Do I simply need an app, a good amplifier, solid wifi connection, smart speaker selector…? No problem if this isn’t the type work you do. Thanks just the same, Steve

Project is to engineer, design, and provide all manufacturing and assembly files and component part numbers from 2 manufacturers for a 4.37 kHz signal generator with 10 Watt RF amplifier, and omnidirectional wire antenna +/- 140cm in length. 12VDC power supply source. 100% duty cycle. Extremely compact design required using one or more interconnected 30mm diameter PCBs.
Refer to attached circuit schematic. The transmitting raspberry pi (TX pi) sends a data signal to a filter circuit. The filter circuit removes the 3v that the rpi sends when there is no data streaming in order to protect the amplifier. The amplifier then sends the data signal down a long wireline to the receiving Pi (RX pi). The problem is that the program uart_rx is expecting to see 3V to indicate there is no data. Instead it sees 0V and thinks this is data so it writes empty values to the file. The scope of this job is to modify uart_tx.c files and uart_rx.c files so that the transmitting program sends a start of file indicator, and end of file indicator. The receiving program should then be able to identify when the data is starting so it can start to write to the file....

Hi, After a Rapberry Pi 4b Breakout Board. The board is roughly, 26x 21 cm in total size. The prupose is to have thid master board that the Raspberry PI plugs onto and then the SUB BOARD PLUG IN/SOLDER ON IT. Existing boards are such as AUDIO DAC AMPLIFIER 5V BUCK STEP DOWN 12V BUCK STEPDOWN MINI OLED SCREEN .96 Inputs for voltage and outputs for audio and a data line for ws2812. Rough layout is something like the following attached image. Regards Tristan

...TD and TA are given in milliseconds by algorithms 1 and 2. Both are simple algebraic algorithms, on which the independent variables are the distance between predefined "R" peaks, and gender (Male or Female). The EKG signal is provided by a BIOPAC 100 Amplifier. Because we are in different countries, please elaborate how the Quality Control will be done. A more detailed specification will be given once we agree in pricing and delivery time. The project is simple, but requires experience in Real Time signal processing. A BIOPAC 100 Amplifier provides an EKG analog signal that can be regulated until 10 Volts. What is needed is to detect the "R" peak of the EKG waveform. After a time delay higher than 85 milliseconds, a Linear actuator is activated to ...
