4x4 hybrid lawn mower
#electronics #esp32 #can bus #kicad #flutter
Remote-controlled mower built from scratch for steep hills, with a low centre of gravity: a petrol engine spins the blade and drives a 24 V 90 A alternator that keeps the LiFePO4 pack charged, while four electric wheel motors do the driving. Two ESP32s talk over CAN bus, one reading a FlySky RC receiver and serving a BLE link, the other driving the RoboClaw motor controllers, brake and engine relays and the cut-height actuator. A Flutter app adds joystick control and live telemetry.

RiftLine
#flutter #flame #firebase #game #multiplayer
Neon three-lane endless runner for iOS and Android, built with Flutter and Flame. Live 1v1 matches use a shared seed so both players race the same obstacles and see each other as ghosts over Firebase Realtime Database. ELO ranks, a seasonal battle pass, daily and weekly challenges, cosmetics, and IAP through RevenueCat.
age_range_signals
#flutter #package #android #ios
Flutter plugin for age verification using Google Play Age Signals on Android and Apple's DeclaredAgeRange API on iOS 26+. Age checks are becoming law in more and more places and each one answers them differently, so this wraps both platforms behind one call: you set the minimum age your app needs, it says whether the user is over it. The answer comes from the user's Google or Apple account, so your app never asks for a birthdate or an ID.

#javascript #userscript #waze #gis
Tampermonkey userscript for the Waze Map Editor that pulls official Slovenian house numbers from EProstor and draws them on the map. Colour-coded circles show which numbers belong to the selected street, which are missing in Waze and which conflict, and one click adds a number to the nearest matching segment.
IskraEmeco AM550 esp8266 bridge
#electronics #esp8266 #mqtt #home assistant
Custom firmware for a NodeMCU (ESP8266) wired to the P1 port of an IskraEmeco AM550 electricity meter. It reads the telegrams the meter pushes out every second, parses power, energy and tariff values in real time and publishes them to Home Assistant over MQTT, which handles further processing, statistics and cost estimates per energy block, so consumption shows up on the dashboard with no cloud in between.
