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...

Hello, I am looking for additional ideas / approached on a LiPo charger circuit. Requirements: Schematic - can be hand drawn if very legible Single cell LiPo battery (100mah, with no secondary protection) +5V input voltage And the final, most difficult requirement... Total BOM cost of <$ 0.20 USD in volume. This will eliminate the typical LiPo single chip charger solutions. Probably will require discrete components. Additional information: Charging source is a USB port so figure 5V 100ma Over voltage charging protection is required. Deep discharge protection is required. There is a micro already available, so a digital I/O and ADC is available for intelligent control. That can be used to enable a series pass transistor, and ADC to monitor voltage. You would need to provide all scaling / and interface circuitry. Low bat indicator is desirable, can use micro ADC if needed.

We are seeking an engineer with previous expertise in KiCAD. We need a PCB converted into a SolidWorks 2014 readable file format. There are several ways to create this: 1: We send you a BOM and a PDF of the board. You model directly in SolidWorks. 2: You already know KiCAD and Wings3D. 3: You have your own method. I don't really care about the method. I just want an accurate 3D representation of our PCBA so we can hand it to our mechanical engineer and insert it into our mechanical assembly. I hope to hear from you soon!

We have a project to build some prototype boxes with a mind to producing approx 10 per week later in the year I want someone to price and build the first box. I will work closely with you to deliver it. The box will hold an intel NUC, a 5 port switch module and aphantom power audio preamp. It must be able to all be powered from POE and provide POE to one of the network outputs. I have sourced the NUC and included details on the diagram I have sourced the POE splitter and injector Only the green items on the diagram remain open to source by you. The case should be plain and simple, standard off the shelf aluminium section is fine by me with custom end plate. but I am flexible and happy with suggestions included 3D printed. Please only send me details if you speak fluent english and send me your skypeID. I would like a price for delivery of the first box - if you need to ask me questions you can caveat your price with assumptions. I will assess the box with videos and photos etc...

I need help putting together a control unit for a custom sous vide. I first looked at using a PID system but was told that a programmable touchscreen control could be the better way to go. I have a little electrical background but this is pass me. I need a unit to control the temp and time like a PID but I need preset buttons to hold set profiles. If this is something you could do please let me know. Thank you.

I am a teacher of middle school and would like to teach kids on how to make a simple project of turning LED lights on. All the items would have to be from scratch. This includes buying the LED lights from scratch, etc. The lesson needs to be created so that it is very easy to understand and list all the items that needs to be created. It also has to explain what each item does and why it is needed.

Need to develop a GPS tracker, Engine Shut Off, and Passenger Weight Checking device for CNG cars. This device will be outfitted onto CNG cars and will transmit the data through GPRS GSM sim to a central server. The central server can send out requests to shut off the engine. If weight checker is not possible, we need a switch for the driver to indicate his ability. Switch up for available, switch down for not available. Each device should cost under $40 USD to produce. The device can be built with micro controller parts found around electronics stores. The server side aspect can be done by us but if you have experience developing software as well, that is a plus. The software for the micro controller will have to be developed by you. Please provide past work examples, your experience, and how you intend to build such a device. Include the code "343" in your response so I know you read the description. Very important that all these parts can be sourced in Bangladesh or...

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.
