A prototype apparatus requires construction for patent work follow-through demonstrating the validity of a new invention concept. The skill required here lies in drawing off two pulsing streams of electrical current from a magnetron to then be fed through two solenoids. Further to this the solenoids closest to the magnetron being associated to a negatively charged plate, the other end of the solenoid furthest away from the magnetron being a positive charged plate, hence a type of pulsing current drawn from the magnetron, negative to positive. A protective casing structure will also need to be constructed around the entire unit. All relevant data and design specs are available at   [obscured]   Once you've viewed the specs there (Gravielectric Paradigm, page 2) and you are confident you can assemble as outlined including the dual pulsing microwave circuitry, please make an offer as a complete project, then further details can be forwarded and discussed to refine the cost, including...

REQUIREMENTS (also see the attachment) 1. We have a small table surface of 4 inch by 2 inch in L & B, and 1-2 cms in thickness 2. When a ball hits/thrown on the 'in -zone', GREEN LED should be lit on the long extended unit (metal). If the ball hits in between the in-zone and the out-zone, AMBER LED should be lit. If the ball hits anywhere outside of the 'in-zone' RED LED should lit. 3. The data captured should be sent via Bluetooth to a smartphone app (the app will indicate where EXACTLY ON THE SURFACE did the ball hit. (the unit will only show different colored LED to indicate hit or miss) 4. Operated by removable coin cell battery, preferably in the extended unit Sensors (and other units/PCB) can be placed INSIDE the table surface or as an attachment BEHIND the surface table (we would like it ideally inside the table) 5. The ball hitting the surface could be made of leather, rubber or resin. All no metallic 6. The unit will be coin battery operated - no exception 7. No ex...

Hello, I am an electronic circuit designer needing thermal assistance with a heating element. I have designed of the electronic control circuitry, but the thermal end is out of my expertise. My goal is to first calculate the power required, second - source manufacturing for the element. The project is a coffee mug (think mobile travelers mug). The requirements are to maintain beverage at 175F. Not heat the beverage from ambient, the beverage will all ready be 175 when poured into the cup. I need real math to calculate how much power (wattage) is necessary to maintain this temperature. Again, not heat, need the lowest power maintain. Final element will be running off of 3.7VDC I am looking for math not assumptions, or guess. If you have any manufacturing contacts / suggestion this would also be helpful. Thank you

Without discussing in further detail what we need fabricated, this product may be difficult to explain to you through email. Essentially we're in need of a square panel (apx. 30"x30") made out of a clear acrylic. This panel will have capacitive sensors fastened to it. These sensors will need to be able to control volume, music controls (play, pause, next, etc.), an LED light strip, and a relay switch that powers two 110v 10watt lights. For the prototype, as long as the material is transparent, we can use anything for now. So plexi-glass, clear acrylic, or any plastic that is transparent will work for this model. The audio components on the microcontroller will need to operate a bluetooth receiver for controlling and inputting mobile devices. It also needs an option of a 3.5mm stereo input that will bypass the bluetooth's audio for direct connection. This will all need to be output to a stereo jack (3.5mm or RCA). For lighting, the panel will need to include three function...

Hello, I need a proof of concept program developed on an Atmel xMega chip with TFT touch screen. The POC will read an input string and continually scroll the contents across the display in a structured format as explained below. In addition, there are some simple touch screen actions required. See attachment for requirements with images. Requirements: Initiate #9 logo on startup, display for 5 seconds Switch to main screen, which contains rotating display of text based messages The main screen contains three callout bubbles, with related message content and image Example screen: Screen needs to scroll content every 5 seconds, with top message being removed and replaced by middle message, middle message replaced by bottom message, and bottom message being replaced by a new message. Every 5 seconds, a new message is added and an older one is dropped off. For example, after 5 seconds, the example screen from above will now look like ? The screen will need to continu...

The way people shop hasn't changed really that much since the inception of the traditional shopping cart. People go to the Supermarket, use the cart provided for them by their local market, to transfer goods from the store to car to home. I believe most american's to be a convenience oriented people, myself included. The idea came to me one day. I was in Costco shopping right about ready to check out, I noticed there were no more box's available and Costco unfortunately doesn't provide any bags. I thought to myself, now I have to load and unload one item at a time. THIS IS HORRIBLE! This isn't convenient at all! How can I change this? How can I make life easier for myself and the everyday shopper? Convenience and time equals money NO? For now let's call it the Alpha Cart. The Alpha cart was designed to be a point of connection for the consumer. From vehicle to store to vehicle to house with no lifting what so ever. A one stop shop! Alpha's (similar to an ambulance gurney) legs ...

Hi! I need some kind of reverse engineering regarding Arduino DSLR trigger from PC application. So, I have demo version of one software witch is used to trigger DSLR camera based on GPS location. Please see schematics here:   [obscured]  /s/ma5zezt904qqiqw/Untitled-1.jpg?dl=0. So I need to replicate that trigger box (in wich is some kind of Arduino board i guess. I need someone to inspect software (.Net Framework) which I would sent you and try to rediscover what arduino components i need to replicate that box. On one side od trigger box is USB cable, and on the other there are two cables. One is simple on/off switch to trigger camera, and other one is connected to flash output on cammera and it sends the pulse back to software to get feedback that camera has triggered.
