ESP32 Embedded Firmware – Smooth Sparkler LED Animation

I am developing a wearable LED headband with a continuous, sparkler-style moving light effect. The mechanical design (SolidWorks / STEP) is fully completed and locked. This project is strictly focused on electronics and embedded firmware — no mechanical design, web, or mobile work. The goal is to implement a high-quality LED animation engine on a microcontroller (ESP32 or equivalent) that produces smooth, continuous motion around a 360° addressable LED ring (~72 LEDs). The animation must use fractional (sub-pixel) position tracking and brightness blending across adjacent LEDs — visible LED-to-LED stepping is not acceptable. Scope of Work: • Develop embedded C/C++ firmware for addressable LEDs (WS2812B / SK6812 or equivalent) • Implement continuous 360° motion with one or more moving “sparks” • Use floating-point or fixed-point math to blend brightness between adjacent LEDs • Create smooth trailing glow and subtle flicker (sparkler-style behavior) • Match motion speed and feel to provided reference visuals • Ensure clean, efficient, well-commented firmware suitable for manufacturing Deliverables: • Firmware source code • Short demo video showing slowed-down motion that clearly demonstrates sub-pixel interpolation • Brief explanation of animation logic and LED indexing • Optional: guidance on MCU/LED selection if needed Out of Scope: • Mechanical CAD • PCB layout • Mobile apps or cloud connectivity This project requires experience with embedded systems, microcontroller programming, and addressable LED animation. Please do not apply if your background is primarily web or mobile development.

Legal Advice – Director Dispute

I am seeking legal advice regarding a dispute between directors which is preventing the company from operating properly, most urgently in relation to opening a new company bank account with all directors authorised. Company background Three directors One director holds 75% of the shares Two directors (myself included) collectively hold 25% No shareholders’ agreement is in place Primary issue – company banking The company’s existing bank account has been closed by the bank under clause 13.2 of its terms. We have been informed that correspondence was sent to the majority shareholder only. Due to a complete breakdown in communication, the majority shareholder is refusing to engage or cooperate, which means we are currently unable to open a replacement company bank account with all directors properly authorised. This is now preventing the company from receiving income, managing funds, and operating lawfully. Related concerns Jointly owned HMO property (licensed for 6 rooms) Ownership mirrors shareholding (75% / 25%) All directors are personal guarantors on the mortgage Rental income records appear to show only 4 tenants No transparency regarding full rental income or confirmation that mortgage payments are being maintained Our concerns Exposure as personal guarantors Risk to credit ratings Inability to access or control company funds Possible breach of directors’ fiduciary duties Lack of minority protection in the absence of a shareholders’ agreement Advice requested We would welcome your advice on: Our rights and remedies as minority shareholders Steps available to address director obstruction Legal mechanisms to enable the opening of a new company bank account Whether formal correspondence should be sent, and if so, the appropriate form and tone

STAR-CCM+ + TAITherm Cabin HVAC Thermal Comfort Debug/Fix

Automotive Cabin Heating Thermal Comfort Simulation Fix (STAR-CCM+ .sim + TAITherm Human Thermal / Berkeley Comfort) We are looking for an engineer who can run and troubleshoot an automotive cabin heating thermal comfort simulation using: - Simcenter STAR-CCM+ (.sim) for cabin airflow/temperature fields - TAITherm Human Thermal / HTE + Berkeley Comfort for occupant comfort outputs Task goal (what you need to deliver) We have a simplified cabin model. Under a cold ambient heating scenario, the current results are abnormal: occupant thermal sensation/comfort improves briefly and then becomes colder again (e.g., TS drops toward -1 and continues decreasing). We need you to diagnose the root cause and correct the model setup/coupling/mapping so the outputs are physically reasonable. Target requirements (high level): - Transient duration: 1800 s (30 min) - Monitoring temperatures: foot/foot-vent zone around ~35°C, head point around ~20°C (exact monitor definitions will be shared privately) - Comfort trend: overall thermal sensation & comfort must be normal/stable (after heating ramps up, it should not “get colder again”) What we expect from you - Identify why comfort trend becomes colder (typical causes include MRT/radiation boundary, incorrect field-to-human mapping of Ta/Tr/velocity/RH, initialization/restart issues, boundary leakage on cut surfaces, etc.) - Provide corrected settings + clear explanation of what was wrong and what you changed - Provide plots/outputs for monitoring temperatures + comfort metrics (TS/PMV/PPD or equivalent) Required experience (please do NOT apply if you don’t have this) - Hands-on experience with STAR-CCM+ transient cabin HVAC/thermal - Hands-on experience with TAITherm Human Thermal / Berkeley Comfort (not only CFD) - Ability to actually run the case (access to software/licenses or a workable setup) Confidentiality Due to confidentiality, we will share the detailed model files and full requirement document after you confirm capability. Please answer these in your proposal: 1) Have you used TAITherm Human Thermal / HTE + Berkeley Comfort in real projects? Share 1–2 lines of what you did (no confidential details). 2) Do you have access to STAR-CCM+ and TAITherm comfort/human modules to run the model? (Yes/No) 3) List your top 3 likely causes when cabin heating comfort “gets colder again” (keywords are fine: MRT/radiation, mapping, restart/initialization, boundary condition, cut-surface leakage, etc.) 4) What is your estimated time (days) to deliver corrected results + explanation? 5）Tell me how much you would charge for my task. —————————— Keywords: STAR-CCM+ .sim, Simcenter, cabin HVAC heating, automotive thermal management, TAITherm 2020, ThermAnalytics, Human Thermal Model, Human Modeling Extension (HTE), Berkeley Comfort Model, thermal sensation (TS), PMV, PPD, MRT (mean radiant temperature), radiation boundary, coupling/mapping, transient 1800s, monitoring points, HDF5 .tdf, .vfs .slf .tlf - Simcenter STAR-CCM+ (Transient / CHT / Radiation) - TAITherm / RadTherm (Human Thermal / HTE) - Thermal Comfort / Berkeley Comfort / PMV-PPD - Automotive HVAC / Cabin Thermal Management - CFD Post-processing / Data analysis (HDF5)

Flutter app - repost 2 due to christmas

ENGAGEMENT TYPE Hourly (Time & Materials) Estimated effort: 22–26 hours total Start: Immediate Level required: Senior / Very Senior Flutter Developer ONLY WHAT THIS JOB IS (READ CAREFULLY) This is a small, precise repair task in an existing Flutter app. There is no greenfield work involved. There will be: No new features No refactors No architecture changes No redesigns No experiments No “suggested improvements” No “I found another bug” unless it can be reproduced locally You are fixing known, clearly scoped issues only. IMPORTANT BACKEND & API CONTEXT (NON-NEGOTIABLE) All APIs and server-side code have been working as late as December 2025. A full Postman collection exists and can be executed at any time to verify API functionality. The backend is Magento 2.4. No backend work is required. No Magento developer work is required. Stripe APIs are live and working. This task is Flutter-only. Any attempt to reframe this as a backend, API, or Magento issue is incorrect. REQUIRED SKILL LEVEL (MANDATORY) You must be: A Senior or Very Senior Flutter developer Comfortable fixing Stripe and Apple Pay issues in production apps Able to read existing code and fix it without rewriting it Able to work independently without supervision If you are not senior, do not apply. NON-NEGOTIABLE ENGINEERING RULE Never update Flutter, packages, or plugins before the existing code is confirmed working. This is a basic rule, yet one that many so-called “senior” developers still get wrong. IMPORTANT CONTEXT (PLEASE READ) The app already compiles. A previous developer requested payment before automated tests were run. That is not acceptable under PPH standards. Testing comes first. Payment comes after. For this reason, the previous contract was terminated. This is shared for clarity so expectations are fully aligned. APPLICATION FILTERS (STRICT) If you present web pages as Flutter references, you are not of interest. If you have no verifiable references, you are not of interest. If you describe yourself as a “full-stack developer”, you are not of interest. If you over-explain, bloat, or try to over-engineer, you are not of interest. I am looking for a specialist, not someone who knows a little about everything. This is a razor-sharp task. Change existing code. Nothing more.

Logo for a family wellbeing brand

ELEMENTS - LOGO & GRAPHIC MARK - DESIGN SPEC Brand context: Soulvive & Elements Soulvive (logo attached as well for reference) is the parent brand focused on helping individuals and families reconnect with themselves, nature, and one another through calm, intentional, life-supportive experiences. Elements sits within Soulvive as a dedicated offering for children and families, designed to support emotional awareness, self-trust, and connection through gentle, nature-led rhythms that fit into everyday life. Elements is not about instruction or performance; it’s about creating steady, meaningful moments that children can grow alongside, while reassuring parents, schools, and institutions through clarity, care, and thoughtful design. Elements is a family-focused brand that is sold primarily to parents, schools, and councils, not directly to children. The identity must therefore signal trust, care, depth, and intentionality to adults, while remaining emotionally safe and non-stimulating for children. CONCEPT: Tree and fingerprint We are gearing towards a symbolic but restrained graphic, rooted in nature, individuality and continuity. We’re thinking of a graphic mark that integrates: - a tree (growth, nature, life, connection) - fingerprint-style lines (individuality, uniqueness, belonging) - implied elements (air, water, earth, growth), without literal icons or labels. This mark should feel: - human - organic - grounded - quietly intelligent - distinguishable and ownable Not: - cute - decorative - whimsical - corporate - overly illustrative The symbol should read as a tree at first glance, on closer inspection, the tree is constructed from fingerprint-like lines. The fingerprint is implied, not literal or forensic Lines should feel organic, continuous, intentional Avoid: perfect symmetry,mechanical repetition, overly tight spacing, high contrast striping Think: growth rings, contour lines, natural flow Not: biometric scanning, security/fingerprint tech, circuit boards Tree trunk and branches should be simplified, elegant, calm. No realistic leaves, detailed bark, illustrative foliage. If leaves appear at all, they should be: extremely minimal, implied rather than drawn, secondary to line structure Elements (air, water, earth, growth) should be felt, not shown. Examples of implication: - upward flow → air - curved continuity → water - rooted base → earth - branching → growth Do not include: literal symbols (waves, clouds, drops, flames), multiple colours to “code” elements Relationship to the word “Elements” Preferred structure: the graphic mark precedes the word “Elements”. OR the wordmark sits beneath the symbol in a calm, balanced way. Rules: - The symbol must not overpower the word - The word must not be turned into a visual trick - No letters should be shaped like branches or lines Typography should be identical or similar to Soulvive Not: playful, childlike, tech-forward, handwritten Please do not explore: logo templates, stock-style fingerprint trees, literal fingerprint ovals, therapy/clinical aesthetics. Several reference images show what we like in principle. What we want you to explore is multiple variations of the same idea with differences in: - line density - proportion - openness vs containment Black on white first before colour is introduced. Colour variations should be in line with the Soulvive logo and fit the objectives criteria. Success criteria We will know the right direction when the mark feels: - calm but not generic - symbolic but not literal - warm but not soft - intelligent but not clever This mark needs to: - reassure adults making purchasing decisions - feel appropriate in schools and public institutions - age well over many years - sit comfortably alongside Soulvive without mimicking it Example logos and graphics we like: https://drive.google.com/drive/folders/1Jieo4wbqsJreXrUg_qYX3xj7qX4vIUh8?usp=sharing
