TIME REMAINING: 15 days, 1 hour
We need to design a system that will place the sensor in the pipe in the direction of waste flow;
Transmit from the sensor unit by WiFi, BLE, or Zigbee.
Fire the sensor every hour or so - blockages usually build up over long periods of time
Send readings back to the server for processing
On setup, the pipe should be free of any blockages.
Analyze the reading over a couple of weeks to build a nominal response for this pipe assembly.
Compare later readings against the nominal response, if the readings are different and getting more different (the blockage is backing up more) then notify that there is a blockage.

#1 Knocker by ajayver
This is a concept of a portable sensor that uses a microphone (or a vibration sensor) to detect clogs. Unlike other models that listen to the water flow, it has a micro solenoid (or a vibration motor) that "knocks" the pipe once in a while, records how it sounds, and reports if it detects a clog.
Let me know if this concept is viable, I can continue working on details.
I believe this is a CAD contest, but if you would need, I can also design and solder the electronics with esp32, print a couple of prototypes, and create a neural network as a microservice that can process the data from the sensor and predict clogs. I can provide a full "idea to a working MVP" service.

Thank you for your submission. We will evaluate all proposals after the submission deadline. I think that it might make sense for you to create a full idea to a working MVP.

I'm also wondering the answer to Kunal's question. I'd be able to handle the development from start to final product but want to know what the scope is for the prize and if the winner will be contracted afterwards to complete the design or you're expecting a full MVP for $640?

This competition sounds interesting. I just wanted to know if you planning to get the asthetic and other design developed here or are also looking for someone to design the entire system incudling the electronics and all.

Portable ultrasound scanner with smart phone app.
Looking for an electrical engineer to build a working prototype of a portable, pre-natal ultrasound scanner that runs off a smart phone App. Combine an existing medical grade ultrasonic sensor (specifications attached) with your designed PCB and a functional App to build a proof of concept. Looking for a very low bill of materials cost. Minimum acceptable BOM cost is $100.
Wirless Surveillance System Single Line Drawings
Desire cad drawings that will diagram the interconnections of various makes and models of video surveillance equipment with appropriate call-outs, to refelect POE connections for catagory 5 data connections, low voltage power, and AC power supply connections and physical placement of equipment. Additionally would like to superimpose equipment placement over exisiting PDF scans of each of the building's electrical floor plans.
CAD Concept for Bracelet Prototype Design is a GPS bracelet that should be designed for kids (ages 3-10). The main use-case for the bracelet will be during a family visit to amusement parks / Shopping Malls etc. Key features 1) Electronic's dimensions: 30X35X10mm 2) Child proof lock mechanism 3) Standard Micro USB input (hidden on the side) 4) Screen/watch is optional 5) Only 1 "Answer/Call" button 6) Slick design !!! (no cheap plastics please) 7) QR code embedded on the bracelet (on the outer layer) 8) GSM slot (similar concept to the iPhone Sim card + eject option)
