We have a room sized about 45-50 square meters, divided into 3 smaller areas. We will have teams of 3-5 players playing in. Idea is that room is kind of magical and dynamic. So people find a wooden tablet with some inscription, then by solving puzzle they understand that they have to place this tablet in particular place on the wall, once they place the tablet on the wall a light will switch on and/or sound will play and/or door will open. Another type of puzzle will be that players with Infra Red remote disguised as an item will open the door. Overall we will have about 12-15 item inputs, controlling about 10-12 outputs. Detailed breakdown of actions players need to do, and what must happen: 1. 5 items are placed/hanged on the wall which opens a hatch on the same wall. 2. Hanging and item on a wall will activate the infrared sensor 3. infrared remote will open the door from point 2(we have the remote) 4. Certain amount of item placed on a scale disguised as a bowl will simultaneousl...

Looking for a freelancer/company to help us design a circuit for a physical game for kids, involving lasers, mirrors and light sensors. The game is a sort of puzzle where the player needs to make a laser beam reach a light sensor by moving small mirrors to reflect the light. It needs to be hooked to a raspberry pi or alike to control the game logic. The game size is approximatively 4m x 2.5m x 0.5m. You will help us translate our concept into a working installation, define what is possible or not, select the components and design the circuit. We will also need wiring diagrams and specific instructions to provide our local contractor. Optionally, you could also provide us with some basic code to run the circuit.

This will be a taxi security cam. It will take photos at certain intervals, store them temporary in the SD and push them to internet to be accessed afterwards. To simplify the schematics, the camera clock should be provided by arduino. I would like to use the OV7670 non-serial camera as it could be found relatively easy in Argentina. And arduino mini or micro. If possible. There are some examples of this camera with arduino on the internet Thanks

Hello I have a working relay system that i use for a few years and now i want to upgrade the code for it. Currently i use ATTINY13A to control a Non Latching Relay-DPDT 5V relay (TAKAMISAWA A5W-K) via a momentary spst footswitch. I can supply the schematics ,Hex files and BOM. Currently, when the footswitch is pressed, the uC is waiting until it is released. When the footswitch is released the relay is activated, along with an LED indicator.When this action is repeated,the relay is switched off. What i want to do is to use the same hardware and to add some features to the switching system, such as- 1. momantaty switching (relay is on only when the footswitch is pressed) 2.Reverse/Standard switching (either having the relay acrivated when the footswitched is released or when it is pressed) *Important feature (that is currently implimented) is that when the power supply cuts out, the relay switches automatically to "bypass mode" My request is for the files ,so i can progr...

Route attached Eagle board to match layout of attached PDF. The schematic should be complete, all desired component models are included in board file. Top DXF of the board is attached, and all parts are dimensioned on the attached PDF. - The GND and 12V lines to the motors (DYN icons) should be large enough to handle 2-3 amps - The GND/3.3V lines to the 28-pin J1 connector should be large enough to handle an amp - Space for wiring on the board may be tight. In the attached Sketch image there is a layout of how we imagined the wiring might work, but when trying to do that actual routing that planned layout may not work out. We can discuss how to slightly reshape the board to get more space if necessary Please inquire as to any questions! Desired turn-around is two to three days

I started with a remodeling company doing, additions in homes and after doing a little bit of plumbing, drywalling, tiling, and electrical i finally decide my career. I fell in love with electrical because its not easy, just something anyone can do, its a art of its own, with that being said should be treated like art. While i work i make sure im am careful and double check everything because i understand that my work quality will affect lives. Its not something to play with it, electricity can do as much harm as its done good for us if not done in the correct manor. This is why i know i am the man to contact for the job. My expertise is in the residential side

Short description: In this system, each table in the restaurant gets a battery powered wireless calling device with buttons. When pressed, this calling device sends a wireless zigbee or generic 2.4GHz message that will be received by one or more of the base stations of the system, which are based on Raspberry PI A+. The master base station memorizes the call status for each transmitter so that said information can later be polled over wifi and displayed by apps run in smartphones worn by the waiters. The apps for said smartphones are developed in a separate project ? you don't have to develop them. Deliverables for this project: ? For the calling device; scematics, PCB layout, MCU firmware ? For the Raspberry base station; software (including installer script that makes the software start upon boot) All software must be delivered with source code, and all source code must be professionally written and well documented in English. Suggested milestones (open to discussion before proje...

From a given circuit schematic and choice of components already made, your tasks will be: 1. To verify the circuit components already chosen, 2. Incorporate best design practices into the schematic, 3. Convert the schematic into a PCB layout choosing relevant packaging and footprints, 4. Review and finalize the PCB design and deliver the source file as well as the Gerber files. The final board will have: 1. An AC side and a DC side with suitable isolation in between, 2. A PWM based switch mode power supply unit (the circuit will be provided to you), 3. Approximate dimensions of the PCB will be 150mm X 100mm, 4. Suitable for assembly by pick-and-place machines. It is vital that you have previous experience working with design of PCBs involving multiple voltage domains (AC and DC on same board). Deadline: 8 July 2015
