Store description excerpt
Vistelo is your complete bench-side toolkit for working with passive electronic components. Instantly decode resistor color bands with precision drum wheels, or point your camera at a real part and let Vistelo sample the band colors directly from your photo. SMD chip resistors are fully covered with support for 3-digit, 4-digit, and EIA-96 marking formats, plus encoding in both directions. Run the numbers with a full suite of circuit calculators. Ohm's Law and power calculations, LED current-limiting resistors, voltage dividers with load correction, RC and RL time constants with cutoff frequencies, and series/parallel network combinations are all one tap away. Results update live as you type, and values flow directly from the decoder into the calculators without re-entering anything. Keep your parts organized with the built-in Bin. Log every resistor, capacitor, and inductor you own with its value, tolerance, wattage, quantity, and drawer location. Search by value or location, filter by component type, check whether you already stock something close enough for a design, and export a shopping list when stock runs low. Build real fluency with Code Drills, a spaced-repetition practice mode covering band reading, SMD decoding, tolerance letters, and capacitor codes. A confusion queue targets the color pairs you keep mixing up. Comprehensive reference tables for color codes, E-series preferred values, SMD package sizes, and tolerance codes are always a swipe away.
