    hi , I am interested in the project that you are doing right now (shopkick sound device) can you give me information about how much you finished the project ?

  • $310 USD In Progress

    I need a device similar to what ShopKick ( have to work with smartphones. First stage we need emitters to work within a range of 4 metters or less. Description:The sound box gives off a high pitch tune that humans or pets cannot hear, but the sound can be picked up by a smartphone microphone. I would like to consider first the device price without power supply and then to know how much a battery and for now C type plug cable for 220v. The box should be small as possible. The device should deliver a constant consistent tune without stopping or interruption. The device should be able to plug into (or use the signal to do so) a computer where you can change or add the tune to the device. The device only needs a small memory to hold one tune at a time.Here is an article of the more popular shopkick device: Here is the breakdown:- Make the device and full testing- Full documentation on the device for replication / mass production- We may also consider prices to develop source code to receive the signar for iOS, Android and Windows Phone. Please quote ASAP, I will take the first quote I like.

    Design and build a prototype of electronic module. The module has to have a small form factor and be driven by an on-board battery. The module has to try to connect to external device by Bluetooth (BLE) every second. Once connection is established the module sends readings from external sensor trough it"s Bluetooth connection. It also sends the Bluetooth signal strength as measured by the BLE chip. The external sensor is connected to the module by two wires, and the reading is done by measuring the resistance between the two wires every 1 second. The module has to include the BLE antenna on board (as a printed antenna). This is a very simple module. The end product is a working prototype that resembles the final product in dimensions, power consumption and functionality. You have to deliver the drawings, software (if relevant), and bill of materials to allow mass production of the module.

    I designed a circuit for my sensors awhile ago and while it is fairly accurate, it does seem to drift and is not as stable as I would like. I am curious to see if expert engineers can offer up a design that offers the utmost stability. A couple Key Points:Power Supply Should be +12VDC - 28VDC (it can be fixed or variable depending on the design but should be within this range.Input: Sensor is linear, but I use a 16.8K Thermistor Curve D to compensate with the change in temperatureSensor Characteristics are attached.Current Schematic is AttachedOutput should remain 0 - 5VDC; Would also consider a 4 - 20mA outputDisplay is not necessary.Microprocessor is not necessary, but if it helps the stability I am open to it.Right now it has two ranges and a toggle switch, I might change this a bit.Cost is obviously a concern, I would like to keep the cost of the complete unit to a minimum without sacrificing performance.For the most part it is a basic op amp design, but I greatly want to improve the stability of the circuit.If you have any questions, please contact me. I am curious to hear your proposals.
