Being able to use Janus Gateway to manage all the video and audio streaming of all the Raspberrys in all the small cars would be a better, more elegant, cheaper (in the long run) and better performing solution. The Raspberrys are connected to an intermediate circuit to control motors and servomotors through the GPIO port. Each one controls 4 motors and 2 servomotors. I am sold some kits to assemble the small cars, although you have to buy the Raspberry, the USB microphone and the batteries separately.

Note - I want someone to make & get one machine ready for me so please bid if you can handle everything from design to manufacturing. I am developing a compact, battery-powered device that continuously feeds a roll of sticky mat across a doorway so the exposed surface always stays clean. The concept is simple: a fresh section of mat is pulled from one spindle, laid flat, and the used layer is wound onto a take-up reel. Here’s what I already know I want: • Time-based automatic control that advances the mat precisely every hour. • A low-profile, walk-safe deck suitable for hospital corridors and dusty construction entries alike. • A rigid steel frame for durability, yet light enough to remain truly portable. • Quiet, sealed gear-motor driven by a rechar...

I’m ready to move GuatePCB (a nearshore PCB assembly factory in Guatemala) from concept to market with a distinctive standalone logo mark / icon (no text included—this is purely the symbol). The core idea fuses the long-tailed silhouette of the Quetzal (Guatemala's national bird) reimagined as elegant PCB circuit traces, vias (filled circles/pads), and solder points. The icon must feel high-tech/precise yet subtly proud of Guatemala—modern, minimalist, organic geometry that integrates naturally. It needs to read clearly at favicon size (16×16 px) while scaling cleanly to large formats like factory signage, embroidery, or product labels. Reference / Starting Point (Please Base Designs Closely On This): Use the attached AI-generated reference image as your...

needs a fresh, minimalist logo that instantly signals two things: cutting-edge automotive technology and reliable repair expertise. The name itself should remain the focal point, but feel free to weave in subtle automotive or tech cues—whether that’s a clean line hinting at a vehicle silhouette, a stylised circuit trace, or any other clever visual metaphor you believe will keep the design sleek and uncluttered. I’m deliberately leaving both the colour palette and supporting graphics open. Surprise me with combinations that balance professionalism with innovation; the only hard rule is to keep the overall feel minimalist. Whether you lean toward a single accent colour on white or a darker tech-inspired scheme, justify the choice in a short rationale so I ca...

I need eyes and feet on the ground at the Patrick County Circuit Court in Stuart, Virginia to pull a civil court file and send me complete, legible copies of everything it contains. This is strictly a document-retrieval task—no legal analysis required. Here is what I will provide once we start: • The exact style of the case, docket number and any clerk reference details. • A signed letter of authorization, if the clerk requests one. What I need from you: 1. Visit the courthouse during clerk’s office hours. 2. Locate the specified civil case file. 3. Copy every pleading, motion, order, judgment and exhibit in the file. Digital scans (PDF) are ideal; high-resolution photos are acceptable if scanning is impossible. 4. Confirm the file is complete by comp...
