PCB Trace Calculator helps you choose copper trace widths for your circuit boards and check whether existing traces are wide enough for the current they carry. Instead of typing one current into a formula, you can sketch your circuit: place components, connect their pins with traces, and the app works out which traces carry which current. A battery feeding a fuse, a switch and two loads gives a wide main trunk and narrower branches, each sized for its own load. … Continue reading “PCB Trace Calculator”

RabatTramNav helps you find your way on the Rabat-Salé tramway. Choose a departure and a destination stop, and the app shows you the route on the map: which line to take, the stops along the way, and where to change lines if you need to. Features • Map of tram lines L1 and L2 with every stop • Journey planner: pick two stops and get the route, number of stops and transfers • Transfer stations clearly marked • Tap any … Continue reading “Rabat-Salé Tramway Route Planner”

Compare your USB charging cables and find which one charges best and steadiest. CableCheck Pro helps you find out which of your USB charging cables performs best — and which ones may be worn out or low quality. It does this scientifically. The app cannot look inside a cable or measure its copper directly (no Android app can). Instead, it reads your phone’s charging behaviour through the Android BatteryManager API and infers cable quality from repeated, controlled measurements. HOW IT … Continue reading “Cable Check”

Decode resistor color bands and SMD codes, and convert between them. Color band decoder – 4-band, 5-band and 6-band resistors – Tap a band on the resistor drawing to choose its color – Shows the resistance, the tolerance and, for 6-band resistors, the temperature coefficient – Shows the matching SMD codes SMD decoder – 3-digit codes (e.g. 472 = 4.7 kΩ) – 4-digit codes (e.g. 1002 = 10 kΩ) – EIA-96 codes (e.g. 01C = 10 kΩ) – R notation … Continue reading “Decode resistor color bands and SMD codes”

Pattern Flash is a simple visual memory game. Some cells on a grid light up for a moment, then go dark. Tap the same cells from memory to clear the level. Each level is a little harder than the last: more cells to remember, larger grids (from 3×3 up to 8×8), and a shorter flash. Rounds are quick, so you can play for a minute or for longer. HOW IT WORKS • Watch the pattern, then tap every cell that … Continue reading “Pattern Flash”

Tap 1 to N in order on a number circle before time runs out. Test your focus. How fast can you find the next number when the clock is ticking? Brain Stress Circle is a quick reaction game. A big circle splits into random cells, and each cell hides one number. Tap the numbers in order — 1, 2, 3 and so on — before the timer runs out. Sounds easy. It isn’t. EVERY ROUND IS DIFFERENT The cell pattern … Continue reading “Brain Stress Circle”

A simple camera app that records video and turns it into genuine slow motion. HOW IT WORKS SlowCam records using your phone’s Camera2 API and automatically detects every resolution and frame rate your camera actually supports, including high-speed capture modes on phones that have them. Nothing is hard-coded: if your phone can film at 240 FPS, SlowCam offers it. If it can only do 30 FPS, that’s what you’ll see. To create slow motion, SlowCam keeps every single frame your … Continue reading “Slow cam”

Inspect and remove hidden metadata from your photos and PDF documents. When you take photos or export documents, your device often embeds hidden metadata inside the file. This can include your exact GPS coordinates, camera serial numbers, device model, creation timestamps, and author information. When you share these files online or via messaging apps, that metadata travels with them. PrivyStrip allows you to inspect what hidden information is stored inside your files and create sanitized, metadata-free copies before sharing them. … Continue reading “PrivyStrip”

It is a preview tool. It is not a film scanner and it is not a replacement for professional scanning or lab work. What it gives you is a quick, readable look at the pictures your own negatives are holding — enough to see what is there, to sort through a strip, or to decide which frames are worth having properly scanned. HOW TO USE IT Display a plain white screen on anything that lights up: a computer monitor, a … Continue reading “Silver reveal”

Foculo is a small game about keeping one moving object in mind. A group of identical white cells drifts inside a dark circle. When a round starts, one of them is red. You get a second or two to find it. Then the red fades to white, and your target looks exactly like everything else on screen. The cells keep moving, crossing and overlapping. When they stop, you tap the one you were following. That is the whole game. There … Continue reading “Foculo”
