Ever wondered why everyone keeps going on about the beautiful colors of the sunset? Having trouble seeing if a tomato is ripe? What about bananas? Or maybe you just find the world to colorful and want to keep it a little more black-and-white for the day? Achromator translates all color from the phone video stream into unique animated textures. It encodes all hues and shades - without loss of information! It even keeps much of the structure found in color, like mixing, gradual blending and complementary hues. The pattern generator can be adjusted to your personal preference - pattern size, speed and selection of individual colors.

NEC Box Fill Calc gives electricians a complete NEC 314.16(B) single-box field check at no charge. When a job spans multiple boxes, the existing Rough-In Schedule keeps labels and corrections together for a shareable handoff. Free field check: - Add conductors by gauge from 18 AWG through 6 AWG - Count grounding conductors, internal clamps, support fittings, and devices correctly - See total fill, pass/fail status, line-by-line breakdown, and the smallest listed standard box that fits - Switch between 20 standard box sizes or enter a custom marked volume - Work fully offline with no account, ads, or subscription Unlock the Rough-In Box Schedule once to: - Name the current project and label each box or room - Collect up to 30 completed box checks on device - See project totals for passing and overfilled boxes - Put every required correction first, including overage, current box, and recommended replacement - Reload any scheduled check into the free calculator - Share or export one complete plain-text schedule - Restore lifetime access on another device Built for electricians, apprentices, and foremen who want to avoid repulls, box swaps, and inspection-day surprises. Important: - Always verify the enclosure's marked volume and local requirements on site. - This app is a practical field aid, not a substitute for code judgment or inspection approval.
