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.

Looking for someone with advanced FEA skills to create a model of a simple impact socket wrench having specific material and dimensions properties (supplied), and then simulate an air impact wrench loading on this socket for the purpose of optimizing the mass of the socket for a specific target load. Modeling the load of an impact wrench is not simple and built in features in AutoCAD are not what we want. This is not the same as a static load, hence the need for someone with the advanced knowledge to model this correctly and simulate needed conditions. Details of hammer mass inside the impact wrench are different for every brand and model, so will need to be approximated. We can supply ballpark figures of rotational load and spikes of impact typical to an average model. Resistance to spinning is based on thread friction between bolt and nut and given CoF with no lubricant. Here we can assume full tightness and allow no rotation, however some torque will still be absorbed or transferr...

Looking for someone who is good with logic and basic understanding of the game of poker. Poker has 10 levels from High Card to Royal Straight Flush. There is no real basic logical sense from one level to the next. I want to make sense of this game by making a kid version that relates to the gameplay of poker. A possible comparison could be Football (US Soccer) so a child can understand the rules and easily memorize the gameplay.

We want to create a custom iphone 6 plus case with a funnel for directing the sound of the iphone speaker at the bottom. The case must be airtight around the speaker to most effectively direct the sound. We want to have this 3-d printed asap. We want a service provider who can create drawing in Solidworks or a similar program and also advise on printing materials. We want the service provider to coordinate the printing and get the part shipped to us. The bid should include costs of creating the drawing and coordinating the printing, but the printing and shipping costs do not need to be included in the bid. However, we would like an estimate of printing costs to be included. Previous experience in creating iPhone cases strongly preferred. US location is also a plus for coordination with printing and San Francisco / Bay Area would be great for in person meetings about future projects. Your proposal should include: 1. Examples of similar projects 2. Completion date 3. How man...

We are looking for a partner who could help us to develop an IOT box which will contain up to 48 home keys. The box should be able to be opened via password provided though the app which we are building already. The Box will have a safe type pin code lock and the password will be provided via the app. Once the user input the passcode, then the door of the box and lock of the specific key will be opened. The box will be powered via ac adapter and wifi/lan cable should be available. The box size should be under 50cm high, 30cm wide and 10cm deep. The box material can be anything light weight but need to have strength that normal human can not penetrate with bare hand. The box must have water proof version and non water proof version. Below is a spec which we assume. Bluetooth Option Spec: - 5V Power supply for controller - 24V Power supply for lock device - Microcontroller module 400Mhz - Bluetooth 3.0 module - Relay switch - Electric door lock device - Developed firmware - 9-...

I have a Bluetooth Low-Energy beacon project that is based on a CSR1010. I have the beacon code working but the beacon function is currently broadcast (transmit) only. Now I need to add the ability to detect (receive) when another paired beacon comes into range. When another beacon comes into range it will trigger a PIO output. Need someone with lots of experience programming CSR BLE chips.

Hi there, I'd like someone to build a 12v circuit for me that provides a 60hz sinewave oscillator. We'll later take this sinewave oscillator and use some MOSFET transistors to amplify the signals. We'll then connect a transformer to create a 12v-to-120v inverter capable of 5000 watts. If you can build the oscillator, that's all we need for now - but if you think you can build the whole project, then great - please indicate that in your proposal. I look forward to your proposal! Please include the word "inverter" in your proposal so that I know you read this project description. Here's some reference material:   [obscured]  /watch?v=VDi_uFSr3w0   [obscured]  /wp/?p=415 Thanks, Mike

I need you to make me a circuit (tangible, not just diagram) that will connect between 2 of my solar batteries (12 V). When the first one dies, I need it to switch to the other (backup) battery automatically and keep them relayed / connected so that the solar panel will begin recharging the first one (that died). Please let me know any info you need and how much you will make me this circuit for. May need 2-3 of these circuits, so please quote me per circuit made. Thanks so much!!

I need a capable poduct designer/engineer for a sheet metal part (see attached sketch) used to mount on a backpack strap. It should be made of aluminium. As the first Batches of the product will be small, it should be laser cut and bended (not injection-molded) and CNC machined. Additionaly (as a part of this job but not shown as a sketch) I need a small wheel (around 5 cm diameter) with a 1/4 inch thread in the middle. For the later manufacturing process I need the CAD drawings converted to step files. Before starting you need to sign the sample elance Non-Disclosure Arrangement. Some model photos upon request.

I'm putting a 21 foot yurt in my backyard and the City (Oakland, CA) is requiring a structural analysis by a licensed engineer. This is so simple as to be almost silly, in that it is a canvas yurt with all the specs on the website. But they require it anyhow. Can tell more on the phone but hoping to barter for someone for a night in my cabin in Lake Tahoe! (or 2 nights mid- week in shoulder season) Email me if interested. Looking to get this completed as soon as possible. Thanks! Kathryn
