Project Brief – Custom LoRa Wireless Button Trigger (USB Keyboard Device) Project Overview I am looking for an experienced embedded systems / hardware developer to design and build a custom wireless trigger system using LoRa communication. The system consists of: Handheld Transmitter (with button) USB Receiver (connected to a computer) When the button on the transmitter is pressed, the receiver should emulate a USB keyboard and send an ENTER key press to the connected computer. The device must be reliable and suitable for frequent use, therefore rugged connectors and proper enclosures are required. System Architecture The system will consist of two hardware devices. Wireless Range: At least 300-500 Meters Indoor. 1. Transmitter (Handheld Remote) A compact handheld remote devic...

Hi, I’m working on a colored flame candle development project and I’m looking for guidance from someone with chemistry experience. Objective:Create solid molded candles (not gel/container candles) that burn with bright visible flame colors such as red/magenta, green, and orange, 3 colour flame candle ideally visible even in daylight. Key constraints for the project: Manufacturing must be simple and scalable. No complicated synthesis or multi-step laboratory reactions. Try to keep things at affordable price, easily available chemicals that can be sourced easily in the indian market And Keep it low cost other online platform are selling it for 15$ for 2 candle around 75-90g each candle which includes labour cost manufacturing marketing packaging and shipping...

⚡️ CALLING ALL CRYPTO-ANARCHISTS & EVM ARCHITECTS ⚡️ Project: The Sovereign Swap Genesis (Phase 1) Forget the $175—we’re here to build the bedrock of permissionless atomic settlement. We are looking for a high-signal Solidity engineer to architect the Sovereign Atomic Swap on Bitnet Money (Sovereign PoW EVM). This isn’t a standard "copy-paste Uniswap" job. This is a research-grade MVP focused on Ownerless Logic, Atomic Finality, and the future of ZK-integrated trustless swaps. If you dream in Opcodes and believe that onlyOwner is a centralized vulnerability, this is your playground. THE ARCHITECTURAL MISSION The objective is to deploy a purely decentralized, non-custodial HTLC (Hashed Time-Lock Contract) on Chain ID 210. We are stripping away the "ad...

I’m looking for a seasoned researcher

I need a complete formulation for a liquid/powder, multi-purpose household cleaner that relies on biodegradable ingredients only. The end product should wash countertops, glass, and light grease without leaving residue or harmful after-effects in drains or on skin. What I am looking for: • A detailed recipe showing each ingredient, its exact percentage by weight, and its function in the formula. • Step-by-step production procedure that could be followed in a small pilot batch (5 L) and scaled to manufacturing volumes. • Guidance on sourcing the chosen biodegradable raw materials, preferably with at least two supplier options per key ingredient. • Data or references that demonstrate expected pH, viscosity, and shelf-life, plus simple tests I can run to confirm sta...

Busco apoyo técnico para llevar de la idea al laboratorio una emulsión botánica de bio-protección a base de aceites esenciales de citronela, lemongrass y eucalipto. Mi prioridad es el desarrollo completo de la emulsión y, dentro de ello, lograr una transparencia absoluta en una solución micelar 100 % estable. El reto incluye: • Formulación y optimización de la emulsión para que sea translúcida, sin fase separada ni turbidez. • Pruebas de estabilidad microbiológica que demuestren al menos 30 días de vida útil en bidones de 30 L. • Asegurar que la emulsión no obstruya boquillas de ultra-precisión durante la aplicación. • Evaluación de compatibilida...
