We are in need of a 3D image to provide to our manufacturer for a new toy product. This should be a very simple project for an experienced 3D artist! We are duplicating the look of a cellular tower that will have a small battery and light. We have attached a sample image that should make things easy to duplicate into 3D and we are available to answer questions to make for an easier job for the artist! If you refer to the attached sample image, this shows the object we are looking to create into a plastic toy. Our design will only be approximately 5-6 inches in height, and 3-4 inches in width at the widest part. The toy will be a simpler version of the tower in the image, and we will only need one of the round drum/dish objects that are shown on the tower. For the toy,...

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

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...
