Hello, The project is modifying and adapting a reduction gearbox to our prototype device in the medical field. It is a standalone gearbox of about 12mm overall dimension, yet without the DC motor. The gear ratio is estimated at 10:1 and we would need both input and output shafts. Also, ideally both input and output shaft will originate from the center of the gearbox or close to it. Note: these are common gearbox with typical size of 12 x 10 x 9-12.5 mm similar to this:   [obscured]  /product-detail/gearbox-dc-motor-12mm-electric-door_1644023247.html Are you interested?

Design all electronics for a sensor that use a voice recognition module. See attached PDF for manufacturer. Can use an alternative module, but needs to receive english words. This module uses pre-programmed typed words that systems listens for. Other modules need to be trained. Would consider other modules, but design fee needs to include simple method to activate voice training. When module detects words- data of this will be sent over TCP/IP via wifi to our server. It would send sensor ID, event, date, and time. Currently we a re using ESP8266 for wifi in other sensors. Good low cost. The sensor will need a method to connect it to the wifi network. Bluetooth or other very simple method. Creating the app to accomplish this should be included. All firmware to be included. The bid should include building 3 test units and all documentation for sourcing in for production in China.

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.

Need a person to use Equest, Trane Tracer or any other HVAC energy analyzer softwares and create energy saving calculations for me. I sell efficient chillers, I'd like to approach buildings and design engineers with an estimated energy savings. This person would need to simulate the building load based on square footage, occupancy, floors, monthly electric bill, and existing chiller. Then build a load profile and compare against my chiller performance data to create an estimate on energy savings I can present to my customer. Please let me know if you have experience doing this. Thanks, Josh

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
