I am organizing an offsite working retreat - a brainstorming session, if you will - and need a logo designed for the materials I plan to distribute for the event.The logo should include the text, "invention convention," as should your proposal title or subtitle to make sure you have read this far. Text should be replaceable so I can swap in the real tagline for our meeting. We are a group of technology-and-data-junkies, inventors, and puzzle-freaks, who are experts in various fields and will be charged with thinking up the next-generation strategy for our business. Some idea-words I thought of are: Ideas, brains, smarts, circuits, data, storage, invention, intelligence, entrepreneur, cutting-edge, technology, future, thinking, expertise, solutions, growth, progress smart changes. Feel free to add yours, too. What I am looking for is a logo, delivered in both scalable vector and hi-res jpeg formats that includes info on color palette, size and aspect, and also any fonts use...

I have a parallax joystick and two servo motors on a pan/tilt turret that I am trying to control based on the joystick position through an Arduino. I have seen this done before and have tried several codes from other users that have done this successfully, but I have not had good luck with these. This turret will ultimately be used to control a spray gun mounted to the side of a tractor from inside the cab. My problem is that I don't know what the problem is. I cant read or write code very well and I don't know for sure if my wiring is adequate. I also don't have time to learn the code right now. I turn-around time on this project to be a few days if possible. I need help to find/write/edit a code that meets my needs, and get my Arduino reading my joystick properly, and sending the correct signals to my servos. I have attached a picture of my wiring as well as some of the Arduino files I have been playing with. I know the right person could help me figure this out very quickly. If ne...

I am building a house, and need help with electrical service load analysis, electrical wire routing design / circuit design, and part list for job. I have some future items that will need dedicated ciruits for the future Future need dedicated circuit: Port a che ( Covered parking)- 4 lights over the garage -Future bathroom and game room possible central AC unit added to over garage I think a breaker panel in the garage and a panel in the bedroom 4 Closet Trying to get a parts list to figure the cost of material for the job as I have several electricians bidding the job, but some are bidding just labor and I am unable to compare apples to apples. Also I wasnt to make sure the electrician do the right service into the house.

I need a custom board designed for the Atmel SAMA5D4 that should be relatively straight forward. I would like for the design to be done in Eagle, but that isn't a firm requirement. The board will have these types of components: 1) LCD connector for a 720p display 2) 256 or 512 MB of DDR memory 3) NAND flash (for the boot loader, firmware, etc.) 4) SD Card for the OS, etc. 5) Various regulators and filters 6) A few I2C/SPI/UART sensors 7) One or two debug connectors I have a good idea of what I need and this project needs to be done fairly quickly.

Need a circuit than can track a pencil or similar type line as a device moves along it and sends signals to two or four stepper/servo motors or other position controllers to keep the device in line by compensating for any drift within 6 mm (or more). The device consists of an inner and outer frame. The outer frame is for large movement. The inner frame is for precision movement. The outer frame moves horizontally, parallel to the line and is not electronically controlled. The inner frame holds the tracking unit. It is the tracking unit that adjusts while the outer frame is moving. If the outer frame begins to move out of the range of the inner tracking unit, an indicator comes on indicating the direction to move the outer range otherwise the inner frame adjusts automatically to maintain position. The inner unit can move via the servo motors or similar position controllers +/- 3 mm. This is the minimum acceptable range. Greater range is desired. Summary: Device tracks along a line Co...

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
