I have an audio source (portable cd player) connected to an amplifier through the AUX In. At the push of a button (preferably wireless) I need to have a device interrupt the current audio source by lowering its volume and instead feed a pre-recorded message to the AUX In to be played on the Receiver. The message is no longer than 30 seconds. This is similar to PA systems where when the announcers starts to talk the music is lowered. These are my constraint: 1. The solution has to be an existing device (or multiple devices) that integrates with my current setup. No computer solution. 2. I need to be able to easily record a new announcement on the device. 3. The cost should be less than $200.

The following are the criteria and requirement of the project. The title of our project is "Experimentation using GnuRadio". We are given two UHD devices. Both are "USRP B100" by Ettus Research A picture of ''USRP B100'' is attached. **Please refer to the attachment** We have two Workstations Computer 1 is Transmitter Computer 2 is Receiver We need to do BPSK and QAM Computer 1 will send a stream ''Hello'' using BPSK and QAM method Computer 2 will receive the stream ''Hello'' Communication with ''USRP B100'' is done using only Serial Number Our ''USRP B100'' has No IP Address, so must call using Serial Number Detail Specs of ''USRP B100'' is attached. **Please refer to the attachment** A sample .grc file is also included. **Please refer to the attachment** For both BPSK and QAM design, it must include the following: Comments for each block used and the purpose of the block Constellation Diagram Bit Error Rate calculation This Project must be completed by July 25...

I am looking to put an accelerometer, stream chip, processor, perhaps a cache/RAM, and battery into a pair of sunglasses. It will take a stream from a mobile device/tablet/other device via Bluetooth or WifiDirect and send it to OLED screens built into Sunglasses. I plan to pay for all parts and labor. Must send Design and then on approval build the design. PLEASE NOTE: This is to build the circuit. Developer need not worry about the screens. This is a separate job. Optics will play a big role in that project. It must stream in 720p or higher at ~25 frames/sec. Must be able to stream any youtube video. Must be programmable with the the accelerometer. Must be reproducible (I want circuit drawings, pictures along the way, etc.) All work will be shipped to me at the completion at my expense. If the worker completes the project succesfully He/She will be invited to a share of the company.

I need the schematics drawn for me so that I can order some PCB. i need the board to include a 5v lithium ion battery charger which i will be connecting leads to and attaching to a mini usb jack. The board will also need a bluetooth transceiver as well as an amplifier in the 6w-10w range. Either with one channel that is 6-10W or two channels that are 3w-5w each. The board will be used to connect to through bluetooth to a phone or computer and then play music through the speaker connected to the included amp, and all run off of the 3.7v-5v lithium ion battery. I AM ONLY LOOKING FOR THE SCHEMATICS NOT BOARD PRODUCTION. I will use these schematics to submit and order PCB's that are as small as possible and include all desired features.

Need help in Advanced digital design course. A quick description of the course is the following, systematic design methods for synthesizing sequential digital circuits using hardware description language, while details of its associated languages too are brought to familiar ground.Specification, modeling, and design principles of sequential systems, as well as design implementation and testing using programmable logic devices and Computer Aided Design tools are studied. Additional requirements; Need to have and be familiar with Quartus II software, need to know how to use verilog to solve problems. Do the report and explain step by step process, include snapshots of the software when the program is running. A format of the report will be given. Web Edition of Quatrus II software (Free Download, No License needed)
