3D Printed Enclosure for a Transistor Tester

There is this cheap and amazing component tester, that works on transistors, LEDs, inductors, capacitors, resistors, diodes, among a few others. It can detect the component and give you their basic properties. For instance, it can give you LCR meter readings, distinguish between BJT and MOSFET transistors, NPN or PNP transistors, detect their gain and threshold voltage, measure a diode’s forward voltage and so on. It’s quite useful! But it has a small problem, its Read more…

SpaceX Falcon Heavy 3D Printed

Around a year ago, after SpaceX Falcon Heavy first test flight,  I found this amazing 3d model for Falcon 9 and Falcon Heavy on Thingiverse from the user chemteacher628. I’ve decided to print it myself, so I downloaded the parts, uploaded them to Tinkercad to assemble the model virtually before printing it, to check if everything was ok. While I was checking it, I’ve decided to make a few changes. Now that Falcon Heavy has taken off again last week, I thought it was a good time to share the modifications I’ve done.
