Practical electronics, hands-on robotics and guided STEM pathways, made just as much for young creators learning at their own pace as for schools that want to teach it properly.
All hardware orders are processed securely through the main RoCrux store.
Our philosophy
We take core ideas from physics, mathematics and computer science and turn them into engineering you can hold in your hands. Ohm's law is just a formula on the board until you skip the resistor and watch an LED burn out. After that, you never forget it.
Physics
In the textbook
Voltage, current, resistance
On your bench
Choosing the right resistor so your LED doesn't burn out.
Mathematics
In the textbook
Ratios, ranges, graphs
On your bench
Turning a sensor reading of 0 to 1023 into a real distance in cm.
Computer science
In the textbook
Logic, conditions, loops
On your bench
An if-statement that decides when a motor turns left.
Two pathways
Equal focus on students learning independently at home and schools bringing it into the classroom. Same projects, same quality. Only the setting changes.
For self-paced and home learners
Guided project journeys
Clear, visual project guides that take you from a bag of parts to real, working hardware.
Self-paced progression
Get the fundamentals right first, then move up to harder challenges when you're ready. No deadlines.
Help when you're stuck
Send us a photo of your circuit and we'll help you figure out what's wrong.
Community challenges
Put your skills to the test in robotics competitions and student showcases.
For schools, academies and educators
Curriculum alignment
Projects built to support what's already taught in science, technology and maths, not compete with it.
Educator-friendly setup
Structured lesson plans and organised classroom sets, so teaching it doesn't mean extra stress.
No coding background needed
Neither students nor teachers need to know programming. The code is ready, and every part is explained.
Institutional support
Onboarding, guidance for educators, and ongoing support for the school's admin side.
The journey
One continuous climb, from assembling your first circuit to solving a real problem on your own. Each stage only assumes you finished the one before it. Tap a stage to see what you build.
The booklet
Not a wiring photo. A diagram you can actually read, the reasoning underneath it, the full code, and the part nobody else bothers with: what usually goes wrong and how to tell.
// light drops → value drops → lamp on int v = analogRead(A0); if (v < 400) digitalWrite(9, HIGH); else digitalWrite(9, LOW);
If it stays on
Your room is darker than the threshold. Print v to the serial monitor, cover the LDR, and set the number between the two readings you see.
