CT Wizard (Clever Tools Wizard) is a free suite of interactive calculators and tools built for DIYers, tradespeople, and the perpetually curious. My name is Steve Gulsby, and I built this site to solve real, physical problems in a digital space.
For more than fifteen years I have worked in electric metering and utility electronics. That work put me inside utility metering systems and municipal electrical grids, where I learned firsthand what happens when the math is wrong in the real world. In the trades, a miscalculation is not a typo on a screen; it is wasted material, blown budgets, and dangerous physical hazards. Over the years I have also trained technicians entering the field, which taught me that most people learn a concept faster when they can see it work on a screen before they touch the real thing.
That combination of field experience and training is what shaped how I build tools. I do not believe software should just spit out a number and move on. It should show you why a system works, let you drag components around, and let you make your mistakes safely in a sandbox before you pick up a tool or cut a piece of wire.
I started Clever Tools Wizard because I was frustrated by the lack of genuinely helpful, interactive planning tools on the web. Most online calculators treat you like a robot: you punch in a number and it spits one back out, with no explanation of the method behind it. I wanted a platform where people could test their logic, visualize their layouts, and break things safely on a screen before they ever picked up a tool.
Every tool here started as a real problem on a real workbench. The Measure Once, Cry Twice DIY tools exist so you can make your wiring and measuring mistakes on a screen before they cost you lumber, tile, or magic smoke. The Sanity Preservation Suite exists because sometimes you just need a calculator that makes you smile.
I do not claim credentials I do not have. What I offer is years of hands-on field experience, a habit of checking the math twice, and a belief that small tools should be small joys: fast, private, and a little fun. Pick a tool and get calculating.
