How I give my AI agents eyes with a single API call

My AI agent was blind.It could read text, write code, call APIs — but the moment I asked it to work with a webpage, it hit a wall. "Go check if this landing page looks broken." "Tell me what the pricing page says now." "Monitor this competitor's homepage for changes." All blocked.The obvious fix: give it a browser. The actual experience: install Puppeteer, debug the Chrome binary path, hit memory limits in Lambda, watch it break on every third-party CDN that detects headless browsers. An afterno

Exploring the Mechanics of a Dual Battery Industrial Notebook

Modern enterprise mobility requires more than just strapping a heavy, oversized battery to a laptop chassis. True efficiency comes from intelligent engineering. A dual battery industrial notebook leverages a split-capacity design to optimize long-term fieldwork. The ONERUGGED N14M, for example, pairs a primary 53Wh battery with a smaller 14.4Wh secondary cell. This specific configuration allows the smaller internal cell to keep the motherboard and screen powered while the user swaps out the larg

I built a local system for spinning up small tools over the past two weeks and just open sourced it

Over the past two weeks I have been building out small saas style tools inside a single system locally to replace subscriptions I was paying for where I only used a very small amount of the available features.Initially it started off with building something to help me analyse my meta ads, then I spun up a kanban board, and then within a week I was able to cancel a couple more subscriptions while I kept spinning up more mini tools (again because I was only using maybe one or two features across v

I built a regex tester that tells you what your pattern actually does

TL;DR: Regex is powerful and unreadable. I built a tool that takes any regex pattern and breaks it into plain English, piece by piece. Below is how the explanation engine works, plus the three patterns every dev should actually understand.I wrote this regex last year:^(?=.*[A-Z])(?=.*[0-9])(?=.*[!@#$%^&*])[A-Za-z0-9!@#$%^&*]{8,}$Four months later I came back to that codebase. Read the pattern. Had absolutely no memory of what it does or why I wrote it that way.And I wrote it.This is the

Preventing Surge Damage with a Wide Voltage Industrial Touchscreen

Electrical grids within massive manufacturing plants are notoriously unstable. Heavy machinery powering up and down causes sudden spikes and dips in power that can instantly fry standard computer power supplies. To safeguard IT investments, engineers rely on a wide voltage industrial touchscreen. The ONERUGGED D10R is specifically engineered to accept a broad power range of 12-24V. This crucial hardware feature acts as an internal shield against erratic electrical fluctuations, ensuring the devi

SnapAPI in Production: The Patterns I Wish I'd Known Earlier

The SnapAPI docs are good. They tell you what each endpoint does. What they don't cover is how to use those endpoints in systems that actually run in production — with error handling, caching, concurrency limits, CI integration, and real framework patterns.I've been building with SnapAPI for a while and I wrote down the patterns that made the difference. Here are the most useful ones. 1. Always use environment variables. Never hardcode.// Bad — never do thisconst client = new SnapAPI('snap_

7 Essential PDF Tools Every Developer and Designer Needs in 2026

7 Essential PDF Tools Every Developer and Designer Needs in 2026If you have ever struggled with PDF manipulation—whether it is merging documents, extracting text, or generating professional invoices—you know how frustrating it can be. Between expensive software, complex APIs, and cumbersome desktop applications, what should be a simple task often turns into a time-consuming ordeal.That is where ElysiaTools comes in. I have compiled a collection of free, browser-based PDF utilities that han

How I Audited 50 Competitor Landing Pages in 90 Seconds (Node.js + SnapAPI Batch API)

I wanted to know what every competitor in my space was doing with their pricing page CTAs. Opening 50 tabs and reading each one would take an hour. I built a script that did it in 90 seconds. The batch endpointSnapAPI's /v1/batch endpoint accepts a POST body with an array of URLs and an endpoint name. It runs that endpoint against all URLs in parallel and returns an array of results.{ "endpoint": "analyze", "urls": [ "https://stripe.com/pricing", "https://notion.so/pricing", "htt

Check Your Landing Page Before Running Ads — A 60-Line Node.js Script

I watched a client spend $500 on Instagram ads driving to a page with no OG image, no clear CTA, and a 4-second load time. The ads weren't the problem — the page was. The ad creative was fine. The targeting was fine. But every click landed on a page that was invisible on social previews, had no obvious next step, and took forever to load on mobile.So I wrote a 60-line script to catch this before the campaign launches. What the script checksThe audit calls SnapAPI's /analyze and /metadata en

AI vs Humans: Who Will Win the Future?

I Finally Understood How to Pass Multiple Values in Redux Toolkit (The Right Way)

Today was one of those small learning moments…but it completely changed how I write Redux logic.I used to think:👉 “Redux actions can only take one value”👉 “If I need more data, things will get messy”But today I learned a clean and scalable way to handle multiple values in Redux Toolkit using the prepare function. The Problem I FacedI was trying to dispatch an action like this:Loan amountLoan purposeAt first, I didn’t know how to pass both values properly.I thought maybe I need:multiple acti

Hero with logos + carousel

I built a simple hero section combining a logo marquee with a carousel.It’s a common pattern in modern product pages. Logos for trust, carousel for showcasing visuals, but I wanted something easy to reuse and compose.This was the result:Here’s the component code:'use client'import Image from 'next/image'import Balancer from 'react-wrap-balancer'import type { LogoMarqueeItem } from '@/components/flx/blocks/logos/logo-marquee/logo-marquee'import { LogoMarquee } from '@/components/flx/blocks/logos/

Free Location Detection in React — One Hook, Zero Configuration

Adding location awareness to a React app usually means signing up for a geocoding service, managing API keys, and writing fallback logic. What if you could skip all of that?30-Second Setupnpm install @bigdatacloudapi/react-reverse-geocode-clientimport { useGeoLocation } from '@bigdatacloudapi/react-reverse-geocode-client';function App() { const { data, loading, error, source } = useGeoLocation(); if (loading) return Detecting location...; if (error) return Error: {

Why React State Management Changed - setState to Redux to React Query

TL;DR — React state evolved from setState → Redux → hooks → Zustand → React Query. The lesson: use the right tool for the right type of state.👉 The biggest mistake developers made for years: treating server state like client state. IntroductionEvery React developer eventually hits the same frustration:"My state is getting out of control. Components need data three levels up. API calls are scattered everywhere. Nothing stays in sync."Over the years, the React community developed several solu

Planetary gravity

It has been a minute since I last posted a devlog, and this is not it but it is coming soon, I promise. Today I want to talk about my gravity engine using Euler's method of gravity. The first step to this process is to make the planets, I just made a bunch of clones that all drew their position onto the screen with the pen extension. There is also another sprite the size of the screen that refreshes it every tick by stamping it onto the screen.Next I gave each of the planets an initial velocity
