We are developing a device for use in controlling functionality of pool filtrations systems through WiFi connectivity. The device will need to perform the following functions: Broadcast WiFi in order to initially configure the device. Store simple configurations based on specific user customizations (Zip Code and Pool Size) Connect to internet via WiFi to obtain data from a external database. Utilize the external data to operate the functionality of the pool pump. (control on/off timing) We currently have a fully operational unit that is built on an Arduino Yun platform. We are looking to develop a sustainable hardware unit that can be used in mass production.

I am looking for someone with PCB Design experience as well as Arduino programming experience. I want to design a 2.4ghz RC Transmitter & Receiver setup. The transmitter will be enclosed with a 3D printed enclosure as well as receiver. I need someone to design the PCB schematic as well as help build it with arduino + program it. A few features that the controller will have are the following: - Lipo battery pack for charging - Can be charged via USB - small handheld controller - programmed in arduino - built in led lights front/rear - cruise control - slow, fast, expert options - 13mph, 20mph, aggressive throttle - option for antennas - no dropping or interference - braking turns on red lights I am ready to start on this project ASAP.

I need a simple circuit & PCB designed for a constant current DC (4.2v 18650 Battery Source) LED Driver. The circuit will run 2 LEDs. I will provide the LED specs to the bidders privately. The circuit must be very compact and efficient (maximize battery life). Deliverables will include: 1. Schematic (PDF) 2. PCB Design Source Files (including exported STEP file of PCB & Components) 3. Component BOM (with sourcing references) 4. All files necessary to submit design to a PCB Prototyping Vendor in USA for production I will provide further details regarding PCB format/shape as well as further details to the winning bidder. This is an extremely simple circuit (very few components are required) and shouldn't take more than a few hours work for the right candidate.

hi we need arduino based board design and firmware. you dont need to build bord for us (unless you are in NYC or close) we can just get schematics and we build breadboard ourselves. We need wifi enabled device that had 1620 lcd, with start style buttons to navigate menu. real time clock chip with nonindependent 3v battery. and web server Functionality: form buttons and lcd enter wifi setup, select available network, enter password if needed (all types of protocol configuration needs to be supported) show that wifi connected, go to next menu item and configure tear time clock like 15:30:00 (25h format) have. then next menu shows IP address. Type IP on browser open web server see our clock with option to change it . You can use any WiFi chop you want, i prefer cheap once like one for $2-3 off ebay. chip or module I will need schematics and firmware. If you close to NYC i can pay for assembling breadboard and bringing it to our office

I am working on a project that deals with multiple different technologies. It will use GPS, Bluetooth, Audio and Visual technologies just to name a few. We are looking to find someone we can closely work with on this project so we would like to set up a Skype interview. If this works for you, I’d like to setup a time so we could talk. Price and duration are negotiable. Thank you for your time, BikeX

The successful applicant will be responsible for a complete 'peer' design review of an existing application. This will involve the review of all components selected, how they are integrated into the design and how the interact with each other. The individual selected for this task will be proficient in the designing of E&I control circuits and be able to produce a report on the current design and any areas that may cause an issue. Experience of burner control systems would be ideal but is not essential. Applicants must speak/read/write english fluently and be able to provide examples of similar types of work completed.
