...1 hour in Littleport, Cambridgeshire on Thursday 1 September at 1pm. Dress code: business casual or lounge suit. Deliverables: the unedited footage, 1080p25 or better, as shot at your best bitrate in H.264, H.265 or comparable format, and your static or animated ident (or plain text), if you want it included in end credits. You will need your own, fully self-contained equipment with battery good enough for an hour or better in one continuous take, and your own transport to the venue (parking is available). Mains power will likely be available, but don't rely on it being where you need it. This is not a commercial event. Physical constraints: Tripod-mounted cameras only.

-In this multiplayer game (1vs1) you and your opponent have to bet an amount of money and then put their fingers in their screens and the last standing takes all the money. -I want the game in iOS and android, but maybe because of the budget we can start only in iOS (it depends) -The 1vs1 will be in real time. -The app have to be simple , because it will help to save and optimize battery and the other reason is the style of the the app (simple) -The app is inspired in the app "Finger on the app"
The project is about the design and fabrication of a small-sized spherical robot. The Design and Fabrication process has been completed but needs someone to write a code in Arduino. I am using TinyPico as my microcontroller, Pololu DRV8835 dual motor driver, Pololu AltIMU v5 IMU sensor, 160 mAh Lipo battery, and a small brushed DC motor from Portescap motors. I need to use the Pololu IMU sensor to control my two-brush DC motor to maneuver my robot to move in a Straight line and circle. Also, It has needed to be wirelessly controlled.
this quote contains the project work as per the requirement or drawing, important output of the model should be voltage, current, power, battery SOC and Battery SOH or state of health. any changes in the requirement will need an extra quote. Thanks Shrikant

We need to design a battery-powered Raspberry Pi Zero realtime linux system that reads SMPTE timecode from audio in (when available) and display it on a 7-segment display - When there is no audio on the input, it generates timecode to audio out using Si5351A board or a DS3231 RTC There needs to be a startup loop that reads the audio input for signal, a 4-way switch for type of timecode, checks status of an open/closed circuit, and a push-button for user input. Once the push-button has not been triggered for two seconds and the circuit is open, then the timecode needs to start generating with the
1. Specifications: (a) Input: 24V DC; (b) Output: 400 Hz AC, 115 V, 2 Amp 2. Sinewave is preferred. 3. Output should remain constant even when input goes down to 6V DC or battery overcharged to 30V. 4. Analog design preferred.
I need to run 3 circuits in consecutive sequence at the rate of 60,000 cycles per minute. In other words, power must...connect the next (2nd) circuit, disconnect the 2nd circuit and connect the 3rd circuit, disconnect the 3rd circuit, and then start all over again, and do this 60,000 times per minute. This is using 12 volts DC, 60 Amps. I also need a variable speed control for the speed of the sequences so that I can run it at a slower speed of sequences if desired. I may decide to use 24 volts and 30 Amps instead of 12V/60Amps, or I may use a combination of the following. I am running this off of five - 12 volt, 12 Amp lithium ion smart batteries in parallel or sequence, to get the desired voltage/amperage. This sequencer and speed controller that you build, must be as portable as...

need to draw 2D and 3D models in CAD software, proper drawings with visuals of a lithium battery box
I need help to design a simple circuit to be sent to have a prototype board made. Requirements 12v 500mA power supply Needs to power a esp8266 board and 2 x 12v circuits on mosfet transistors switched by D1 and D2 output pins. One 12v circuit is a 4.8w brushless motor and the other is an LED light strip. Similar concept to ( - from about 27:30, but I want to switch lights and a motor separately with the esp8266, so two of these together. I have it working on a breadboard (attached), but need circuit schematics to give to the company to make a prototype board.
I have a couple terabytes of video and audio I would like to take on my road travels in my camper. My hope is to have someone build a small streaming media server I can watch and/ or listen to on my iPad, iPhone. It is key that the Pi runs on 12v power with an on/off switch for when I am not utilizing the server. I would like to be able to run either an NVMe 2tb Storage drive or plug in via usb 3.0, 1 to 2 SSD external hard drives. It will need to be able to stream this content over an existing mobile network consisting of a Netgear Nighthawk Mobile 4G router and TP-Link AC 750 travel router. Or plug directly into the Netgear Nighthawk ethernet port to access files over a network. If you have ideas on how this idea can be improved, please elaborate.

Hi there, My name is Nada and I need to create a wireless (battery operated/chargeable) water resistant/proof homeware product. I will disclose more about the product once there will be a disclosure agreement between all involved parties. Best regards, Nada Al-Bader
I require a circuit that detects the presence of water when 2 probe wires are submerged. The dimensions of the circuit board should be 54.5mm x 21.5mm The circuit should operate at both 9v and 12v The LED should only illuminate when the resistance between 2 probe wires falls below 10kOhm The power, LED and probe wires will be connected by XH 2.54 connectors: Power is to be supplied by an XH2.54 connector with the polarity in the image provided The LED is to be connected by an XH2.54 connector (polarity independent) The probe wires are to be connected by an xh2.54 connector The surface mounted XH2.54 connectors should be orientated vertically (as pictured) so that the surface of the board can be coated in resin to waterproof it.
