@TobyRobertsPi from @Raspberry_Pi has written an article about my flight computer! To me this is a dream come true 🚀

You know your life revolves around rockets when you design your pressure chambers to fit inside your hand luggage.

@rdotapps @rpimagazine Thanks! I'm using a shunt resistor to convert current to voltage and an operational amplifier to amplify and feed the voltage to an ADC.

Evaluating different kinds of fabrics for building water rockets. From left to right: fiberglass sleeve and tape, carbon fiber sleeve, and carbon fiber + Kevlar sleeve

@AirCommand A lawn dart?

Now the mandrel for the fiberglass water rocket is complete (tap on the image to enlarge). I have glued the PETG 3D-printed sections with Sikaflex 554, an adhesive used in vehicle panel assembly.

Next step: reinforcing the cylinder with the glass fiber sleeve.

@rpimagazine Happy #makermonday I have been working on the development of my low-noise precision power supply based on the #RP2040. Work has been slower than expected but very educational since I had to deal with some dark-electronics magic.

@rpimagazine Happy #MakerMonday! To power my projects I have designed this precision low-noise power supply. It is capable of sourcing 20V@1A with an #RP2040 monitoring voltage, current, and temperature.

@Christianskovly @tindie Thank you Chris. I will not stop creating things. On the contrary, I will be focusing on doing electronics for Science projects at the University and also for educational purposes. Good luck with your rocketry projects. I'm still very much interested in hearing about those.

[DanInvents @DanInvents]

After 5 years of selling electronics on @tindie I have decided to close the store to concentrate my time on the things that matter most to me. Thank you all for your support, it has been a very educational experience.

I will still fly rockets for fun and educational purposes.

@AirCommand Yes, I think so. That is why I ordered one that is almost 2 meters long.
