RTLapseCAM V2: Resin Printer Time-Lapse with TTGO T-Display & GoPro

Not being able to leave well enough alone, I'm onto V2 of RTLapseCAM. A quick re-cap - the purpose was to take time-lapse photos of resin prints (using layer transitions) and stitch them together into a video. In the original setup, the GoPro sat stationary and RTLapseCAM triggered the photos. The result was ok, but it just showed the print rise out of the bed. I wanted to take it to the next level by…

Lepin Baja Trophy Truck (23013) Build / Lepin vs LEGO Comparison

3D Printed RC Hex to LEGO Hub Adapter

After building BluCrawler, I wanted to see what other possibilities there were with builds using RC crawler tires.  LEGO is not there yet with similar tires (closest are the Claas Xerion tires - but they are not crawler tires).  Anyway, it's challenging to mate a LEGO hub to an RC tire.  There are aftermarket adapters out there, but they are expensive, so I decided to design and print my own. The STL file is available on…

BTBox – LEGO Power Functions Bluetooth Controller

I've been on a bit of a LEGO Technic/Mindstorms hiatus for a while - ok, it's been 7 years!   I have an I've been spending much of my hobby time making my own DIY projects / IoT stuff all while mastering Arduino.   That changed a few weeks back when I came across THIS.  I've been thinking of getting an RC crawler for some time, but it struck me that I have 95% of the…

BluCrawler – LEGO Rock Crawler with BTBox Bluetooth Controller

First I want to give a shout-out (and credit) to PunkTacoNYC as BluCrawler is based off his Chilli Crawler - this is his creation. I'm  just taking it down another path.     You can also find published instructions if you want to build it yourself.  For some time, I wanted to get an RC crawler, but they can be $$$.  When I came across PunkTacoNYC's Chilli Crawler, that was I figured I had 90% of the…
