We need a correct and simulated circuit diagram for a phone charger. must go from american standard (USA) AC to iPhone 6 requirement. We would like to use the least amount of components possible, so that it can be very compact. However, it still needs to function of course, so all necessary components shall be included! Thanks for looking! references: 1.   [obscured]  /2012/03/inside-cheap-phone-charger-and-why-you.html 2.   [obscured]  /2012/05/apple-iphone-charger-teardown-quality.html

I am looking for a research study analyzing current mesh network technology pertaining to a particular application. The network must be scale-able up to 1,000 nodes that transmit sensor data and receive control information. Data transmission rate is not a design driving factor. Range between each node is limited to approximately 100 m in an outdoor hillside environment. Power consumption is in fact a design driving factor and shall be minimized as each node is solar powered. Current design implementation calls for Xbee hardware. This study should include an analysis and comparison of protocols associated with the Xbee hardware such as Zigbee, Zigbee Mesh, and Digimesh. Other hardware/software suggestions are welcomed as long as they have the same footprint as the Xbee modules. The study shall conclude with a design recommendation, along with a basic implementation instructions. It is important to note that each network node communicates with an arduino, and must act as a ro...

This is for a total of (2) circuit boards to be completed. This design is happening concurrently with the speaker cabinet design and will require collaboration unless one person / team bids both parts. The first board: - is approximately 3" square with a 7/8" hole in the center to clear the speaker magnet. The first circuit board shall contain: 1. An RF Receiver. 2. An approximately 2 Watt audio amplifier 3. A dual-pole audio filter to apply the proprietary sound curve (to be provided to the winning bidder). 4. Volume up and down buttons (brought to outside of cabinet, working with the cabinet designer). 5. Battery charging circuit for a battery capable of operating the speaker at a reasonable listening level for at least (4) hours on a single charge. 6. Connectors for speaker, battery and external battery charger. 7. Provision to turn unit on and off (brought to outside of cabinet, working with the cabinet designer). The second board: - should be smaller than (2")x(...

We need a custom interface card designed and fabricated that will accept a NGFF PCI card (such as the Intel 7265NGW) and adapt it to the proprietary 18-pin wireless card connector found in the current line of Apple MacBook Pro/Air models. Note: this is for the wireless card slot, not the SSD. The adapter card should plug into a MacBook Air wireless card slot (6+12 pin) and have an interface on it that accepts the NGFF card and routes all pins accordingly. The adapter card must be sized to fit inside the MacBook Air and allow secure attachment of the card to the adapter, and the adapter to the main board. While there are currently adapters for sale on eBay that allow using the Broadcom wireless cards found in these Apple MacBook Pro/Air models in normal Mini-PCIe slots, I need the reverse interface: accept an NGFF wireless card (as Mini-PCIe will not fit inside the MacBook) and convert it to the adapter found in the MacBook. This is for the hardware adapter only - no drivers or oth...

I am needing a charge controller for a AC coupled PV system (micro grid). My current system: I have a grid tie system connected to an off grid inverter forming a micro grid. The batteries connected to the off grid inverter are LiFePO4 batteries, which work good. However when the batteries get charged, this turns off the grid tie inverter, forcing the system to run off batteries only, until the grid tie inverter turns back on. It will continue to do this on/off cycleing. I would like to have a charge controller that will monitor battery voltage, and amps going into the battery bank, and when the batteries get near full, it would start ramping down the power output of the grid tie inverter. I don't know the best way to do this, But it may be possible to put some sort of variable resistor on the line going into the inverter from the panels..? But I want to basically regulate the power out of the grid tie inverter to charge the batteries slowly. We would need to be able to program...

I need to print a circuit for a new keyboard layout, to begin with... This should be very simple with the right equipment. I need two flexible sheets printed. I will put between them another sheet and when I press at specific locations, the top sheet will go through the middle sheet and connect with the bottom sheet, thus acting like a switch. The main requirement is that all connecting traces end up on a pin flap of specific size and specifications. Take a look at the picture. I want something like that, but with the keys rearranged. I will provide the rearrangement.

Hello, Here is the premise of the design: - We have a project that opens and closes a gate using a 4" linear actuator. We need to be able to develop a circuit board that allows us to extend or retract the actuator using an NFC tag and and through a phone app.. - We will be providing the customer a phone app where they can enter in the Gate's ID and after they do that from their account on their app, it opens and closes the gate. - We will also be providing them the option to use a NFC tag to do the same. We are looking for someone who can design us a circuit board so that we can but the individual parts and build ourselves. Parts that I believe we will need: - Linear actuator to open and close the gate - battery source to power the device - NFC reader to read the NFC Tags - Wifi Module to connect to the internet to receive commands from the phone app Thanks

I need help designing a light switch that can be shut off from your phone. I'm not sure what the best bet is in the way of circuitry. The app will be very simple. It will be one switch that uses bluetooth to flip a switch to turn a motor on in the switch plate cover that will mechanically flip the switch. The electronics will be housed in a plastic switch plate cover. I would like to know what you think I could have the circuit produced for. Thanks!!

Dear Joseph, We admire your experiences, skills, and services. We are a passionate small group of young people in California dedicated to building new, affordable technologies that improve people's lives. Since we are at an early stage in our startup with a stiff budget, our job is currently three-part in order to complete our 3D design and transition it for production and campaign it initially on a crowdfunding platform (Indiegogo or Kickstarter) that accepts our product to showcase to backers. The three job parts are as follows: 1) Two PCB additions 2) Digital product test (Autodesk or like) 3) BOM Our 3D design is for our vacuum-like microelectronics, which come in a pair. We anticipate a MCU in our PCBs that connects a custom-built microvacuum, 1202H004BH flat BLDC micromotor (or smaller), UVC microlight, photomicro sensor, Bluetooth, 1.55V 110mAh cell battery, and on/off button. Bluetooth is to allow them our two microelectronics to synchronously do the same thing. Our goa...
