Farm monitoring and control: live temperature, humidity, water level, pH, soil moisture and TDS readings, with pumps and lights switchable from anywhere.
A connected farm system for Tech IQ's smart-farming programme. Field sensors report box and water temperature, humidity, water level, pH, soil moisture and dissolved solids (TDS) to a central dashboard, which also flags warnings and risks across multiple sites on a map.
Operators can switch the fish-pond pump, three irrigation pumps, lights and spare relays remotely, schedule them on timers, and use weather prediction and automatic sensor calibration to keep readings accurate.
A custom controller PCB with a SIM800L GSM module, on-board power regulation and a 16-channel 10 A relay bank for switching pumps and loads over the mobile network.
Designed and assembled in-house: a main controller board with a SIM800L GSM modem, buck-converter power stage and screw terminals, paired with a 16-channel relay board rated at 10 A per channel.
It lets sites without Wi-Fi or wired internet control pumps, lights and machinery remotely over the cellular network.
A servo-driven robotic arm with a geared gripper. The parts are 3D-printed in-house and it's controlled by an Arduino.
A multi-axis desktop robotic arm built from 3D-printed links and a rotating base, driven by metal-gear and micro servos. The geared gripper picks up small objects, and the Arduino firmware coordinates each joint for smooth, repeatable motion.
Four ultrasonic sensors around an Arduino Nano that sound buzzer alerts when obstacles come close. We designed the circuit and built it on perfboard.
The circuit was laid out in Fritzing first, then built and soldered on perfboard. An Arduino Nano polls four HC-SR04 ultrasonic sensors and drives buzzers as objects approach, giving all-round proximity warnings for mobility aids, vehicles or machinery.
A web dashboard for an accounting practice that tracks every client's accounts, VAT, payroll and self-assessment deadlines in one place.
Each client account shows its year end, filing deadline, days remaining, bank-statement requests sent and received, preparation stage and status. Overdue and waiting items stand out at a glance, and staff can request statements or add clients in one click.
A bot that captures a live sports-wager feed and writes every bet, with its risk, win amount, agent and timestamp, into Excel as it happens.
A Python automation that watches a live betting source around the clock, parses each new wager (customer, type, agent, description, risk and win amounts, time) and appends it to a structured spreadsheet in real time. The data feeds the client's position-tracking and reporting.
Three infrared obstacle sensors wired to a Raspberry Pi's GPIO, with Python code that detects objects and triggers actions.
A Raspberry Pi reads three FC-51 infrared obstacle sensors through its GPIO pins. The wiring diagram was documented in Fritzing, and the Python service turns detections into events for counting, robot navigation or access triggers.
