... and balance functionality, appeal, and compliance with Australian standards. Consider materials, structural design, storage for dog treats, power source, ease of cleaning, waterproofing, and compliance with Australian road safety laws (lighting, brake systems, towing limits, signage visibility). The unit will require power which could be supplied via a battery to be charged prior to use, and solar panels and the vending machine will need refrigeration. Step 1 for Design Contest – Concept Design & Renders Develop concept sketches and 3D renders that show the overall look and feel of a mobile dog treat vending trailer. These should also include branding using a generic name (until the real name is supplied). Focus on friendly, pet themed branding, approachability

I’m updating our drone-industry training platform and website and need a cohesive library of flat, single-color icons to illustrate key concepts throughout the lessons. The set will be strictly informational—no alert or navigation symbols—so think of visuals that clarify procedures, components, and data points such as flight planning, weather checks, sensor types, battery health, compliance notes, and similar topics learners encounter in UAV coursework. The look must stay true to a modern flat style: clean shapes, consistent stroke weight, and solid fills that reproduce well in both digital modules and printable PDFs. Because everything sits on a monochrome palette, nuance will come from negative space, line weight, and smart use of solid versus outlined areas rat...

I want to build a small, self-contained charging station that wakes up only when it “sees” a bottle and a can. The core will be an Arduino (any recent 32-bit board is fine) tied to a solar panel and battery pack. A lightweight AI vision module or camera running something like TensorFlow Lite or OpenCV should continuously—or on a duty-cycled basis—look for bottles. The moment a bottle is detected, the system must move straight into the charging routine without waiting for external confirmation; no alerts, no logging, just automatic activation. What I need from you • Complete Arduino firmware that integrates the vision trigger with the charge-controller logic. • A schematic / wiring diagram showing how the camera, solar panel, charg...

I need reliable help to capture a two-hour workshop in Ridgedale on March 6, 4:00-6:00 pm.
