Hello, I'm designing a board that includes the Atmel SMAD21G MCU and would like to know what's the bare minimum needed in order communicate with the MCU with its on board USB. This MCU is also used with the Arduino Zero and two USB are used there, one for programming (EDBG) and Native. I want to use only the Native one, and maybe also upload the Arduino boot loader there if possible.

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.

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. The power source of the inverter will be a 12VDC deep cycle battery rated at 110ah @ 20 hours. The battery will also be connected to an alternator providing 100 amps at 14.3 VDC. 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 I'd like the inverter to be as close to pure sinewave as possible, but that objective will be limit...

Hello, I'm currently adding to a robot prototype I have, and would like to work with someone who has experience in working with manufactured products. Ideally you are a mechanical/electrical engineer or an industrial designer that would either help with the internal electronics and motors or a designer who will help with materials and 3D designs that are ready for manufacturing. The things I have already worked out are: - The way the robot navigates - Self balancing on ball (see picture) - Dimensions The things I need work on: - A way to interact with the robot - Developing the arms to fit the design - Work with parts (micro processor and such) to help when it comes to manufacturing

I am looking for a circuit designer (and possibly builder) who can use Broadlink Home Automation DNA to create an item that work through the Broadlink RM PRO to call lighting scenes. Broadlink is an existing semi-open source home automation system manufactured in China. The electronics seem quite high quality and they have created an aspect to their system called Broadlink DNA. This is a way that almost any other electrical appliance can communicate with the Broadlink hubs. Broadlink is a way of storing and centralizing remote commands for various light switches, TV and airconditioning systems. By using an APP on your mobile the system calls the stored commands and broadcasts them. What I am looking to do is create a unit that has a set of buttons that can be programmed through the APP to call scenes from the Broadlink. The scenes are a series of commands that activate a set of devices. This could be a "arrive home scene" where all the lights in a living area are switched ...

Hello, I am looking for ideas / approached / protocol suggestions on a wireless device implementation. Please do not bid on this if you do not have working experience with this type of network! I will not pay if you do not have real experience! My application has a master base / router to send out ON and OFF commands to the end devices.Each end device needs to be individually separately controllable. The end device is battery powered and controls a light. There is no real data to send upstream, so one way may be an option. The tricky part ... it needs to support 500,000 devices under the same roof. The protocols I have reviewed thus far will not support this many devices. So I am looking for protocol suggestions and frequency bands. Again DO NOT respond if you do not have real, successful, hands on experience! Thank you PS this device does not have to communicate on or over the internet. Additional information: The network topologies is open. I am able to use wired or wireless re...
