Networks, displays, energy, security, solar, and 3D-print planning. Live tools are linked first; planned tools are labeled until the calculator and supporting content are ready.
Estimate device-level monthly and annual electricity cost, compare the largest loads, and model up to six appliances from actual usage patterns.
Estimate a bill from your actual rate and fees or compare transparent flat, tiered, and time-of-use example structures.
Turn slicer weight or filament length into per-print cost, batch demand, waste and failure allowance, and an inventory shortfall plan.
Screen a rooftop system against usable roof capacity, current electricity use, target bill offset, installed cost, degradation, and verified incentives.
Model simple payback, break-even, NPV, IRR, levelized cost, degradation, rate escalation, export value, maintenance, and optional financing.
Estimate upload, download, backup, or migration time from dataset size, connection speed, and realistic sustained efficiency.
Plan simultaneous household or office activity with visible headroom, or calculate data transferred at sustained bandwidth.
Plan a pre-slicer FDM job from part envelope, layer profile, infill, supports, speed, overhead, setup, and sequential quantity.
Check a masked password locally or generate one with browser cryptographic randomness—without putting the secret in URLs, analytics, or sharing.
Open a live tool for calculator inputs, results, formula context, and published examples.
