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...

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!!

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...

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!

I am looking for a device that will wake a child up and remind them to go to the bathroom. I want this alarm to have a wireless shut off button that can operate on the other side of a house (50 feet). I would also like this device to be set, shut off, and monitored though a app on iPhone or Android. The main unit I would like it to be plugged in with a battery backup and the secondary unit to be battery powered.

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...
