Small detail, big impact: upgrading wire reliability in MySat

🔧🚀 In space engineering, even the smallest detail matters. Especially when that “small detail” is a wire that decides to detach at the most inconvenient possible moment.

In the MySat kit, we use several components with soldered wires: light sensors (photoresistors), status LEDs, and our beloved Star LED. Historically, these were also the most frequent candidates for the “unexpected mechanical failure award”.

Previously, we protected the solder joints using standard heat-shrink tubing. It worked… until curious future engineers (a.k.a. our users 😄) started bending wires with scientific enthusiasm. So we decided to run a series of tests using heat-shrink tubing with an internal adhesive layer.

The results surprised even us:

• More than 10 pull and bending tests
• Joint strength increased to over 5.9 kg
• Standard heat shrink showed ~2–3 kg resistance
• Much better durability under repeated bending cycles In simple terms: it is now significantly harder to accidentally break a wire.

We still do not recommend using MySat as a towing cable though. 😉

Starting from July, all wired connections in MySat will use adhesive-lined heat shrink tubing.

And this is just the beginning. For the upcoming stratospheric version of MySat, we plan to switch to ultra-flexible silicone wires designed to withstand vibration, bending, and the harsh conditions of near-space flight. We’ll share more detailed test results during the development of the stratospheric edition.

🚀 MySat is an educational kit that allows you to build your own satellite following simple step-by-step instructions, run real space experiments, and understand how modern spacecraft actually work. You can buy you personal satellite (CubeSat): https://www.mysatkit.com/product/mysat-university-kit/

Because real space engineering doesn’t start with a rocket launch – it starts with attention to every single wire!
