I’m opening two fully-remote internship slots on ExamDuo, the learning platform I’m building to help students study smarter. As a final-year design student, you’ll take the lead on screen design in Figma—your layouts, visual states, and micro-interactions will move straight from file to production. Alongside that core work you’ll dip into user-journey mapping and quick usability checks so each release feels cohesive and intuitive. You’ll collaborate with me and my co-founder every day, dedicating roughly 4–6 hours to design tasks, async feedback loops, and short stand-ups. The role is high-ownership: if you craft it, you ship it, and you’ll see live metrics on how students interact with what you’ve created. What you get in return is a...

The task is to design a compact PCB that drops straight into an SCX 1/32 car so it can run on a digital track. I want the board to read the track’s reed-sensor signal, let me assign any of 20 unique car IDs in firmware, and expose a surface-mount USB-C port on the edge for easy flashing once the body shell is back on. Size must stay close to the original analogue board footprint (about 24 × 18 mm, height under 6 mm) but I can adapt mounting holes or connector positions if you have a cleaner layout idea. Power comes from the standard track pickups (nominal 14–18 V DC), so include an efficient buck or LDO to feed the microcontroller and reed circuitry. I haven’t locked the MCU yet; pick anything small, inexpensive, and easy to program—ATmega, STM32, ESP32, or s...

I’m building a light-hearted, pick-up-and-play PvP game where players fight with anything but the usual guns and knives. The core idea is simple: small teams drop into compact, purpose-built arenas and scramble for randomly spawned items—rubber chickens, enchanted brooms, exploding soccer balls—anything that feels quirky and fun. Matches should stay quick, chaotic and above all casual. Match Formats The game must recognise three queue options and load the correct map layout automatically: • 1 v 1 • 2 v 2 • 3 v 3 Arena System Each format gets its own self-contained arena. I’m open on visual style for now, so feel free to propose an art direction that suits a playful, non-violent tone. What matters most is tight level design that keeps pla...

I print 4–5 m cotton lengths every day with a single colour. Right now I block-print each piece by hand with wooden stamps, lifting, realigning, and stamping the fabric five times before rolling it forward. The manual cycle is accurate but far too slow, so I want to replace only the stamping phase with a faster, low-cost, semi-automatic alternative based on screen printing. Here is the workflow that must stay: I will still feed, tension, and roll the fabric manually between passes; patterns change daily, so the tooling has to let me swap a screen or frame quickly without expensive re-registration steps. Key goals • Screen-printing mechanism that repeatedly places one top motif and four-to-five evenly spaced repeats in a single travel. • Compact footprint suited to a s...
