I'm in the process of designing an electrical circuit for my garage. I will need help with picking out components (5 ea) and making them work together for desired results (off the shelf parts preferably). It includes: 1. Battery (9V, 3V, or 1.5V) 2. LED light 3. Small solar panel (to keep the battery(s) charged). 4. LED (bright green, 2" in dia min) 5. PIR sensor (triggered by human presence) I have a basic schematic but it needs to be messaged with correct values and part #'s.

For this job, you will be required to answer all the PRE-LAB portion questions for each experiment by showing the work and calculations. You will then set up the answer in a properly formatted Data Sheet in a Microsoft Word .doc file of each laboratory experiment. Laboratory Experiments 1-3 have already been completed. You will only need to do the PRE-LAB for Experiments 4-10. To view the pre-lab questions, please check the file: "Electronics Lab Manual.pdf" View the EXAMPLE files to see how the work was done and how to set up properly. The only real work is completing the calculations and showing the work for the pre-lab questions. Skills required: Electronics, Circuitry, Knowledge of Components, etc. You may use circuit simulation software to check your work and build schematics, as well as taking screenshots of the schematics to include. For Micro-Cap 11:   [obscured]  -soft.com/download.shtm Compensation is negotiable.

ISSI is an IC company (  [obscured]  ) doing mainly LED drivers and audio. We are embarking on developing an 8 pin package LIN based RGB LED driver. We will purchase the 8051 and LIN protocol IP from an IP vendor and use our own RGB LED driver such as IS31FL3196 and LIN phy. This will be two stage development, first stage is FPGA (LIN and 8051) interface to IS31FL3196 and LIN phy for proof of concept and SW/FW development. Second stage is merge IP and ISSI technology to make IC using Tower Jazz foundry. There will be firmware and GUI development.

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...

Hi, I have a mechanical engineering background and an idea for a device, but do not have experience designing electrical circuits or selecting components for low power usage. I need your help to select an actuator-battery system and design circuitry that minimizes cost, physical space, and energy usage. The essential function of this device is to move a small actuating arm a very small distance (~2mm) once every 5 minutes. The motion should be linear, so using either a micro-solenoid, or a motor with mechanical linkage would be appropriate. The device will be portable and battery powered, and be as small as physically possible, subject to cost and battery size constraints. Battery life should be long, similar to a wristwatch, if possible. I hope the device can be powered with a coin cell battery to minimize size and cost. The device needs some type of switch to turn it off when not in use. So I need your help to select: i) A low-cost actuator (solenoid, stepper motor, watch m...
