Lepin Baja Trophy Truck (23013) Build / Lepin vs LEGO Comparison
Let's start by clearing the air. I'm fully aware of what Lepin is up to. I'm an AFOL and have been a dedicated LEGO fan (mostly Technic and Minstorms) for over 40 years. I have spent more $ on LEGO than I want to know. Am I a purist? Somewhat. I didn't really pay much attention to knock-off LEGO brands as I just assumed they were crap, so I ignored all the media about them. …
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…
HiTech HS-225BB LEGO Servo Mate
I'm looking at alternate steering options for BluCrawler as the LEGO PF servo motor doesn't cut it, and I'm not satisfied with other LEGO-based approaches I've tried. So, I'm headed into unconventional territory that may cause my AFOL brethren to shiver. I'm looking at integrating a HiTech HS-225BB Servo to manage steering. If it works, I'll add one to the front and rear to give me the throw I need for a tight turning radius as well…
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…
LEGO Technic Wire Storage
What better way to store my wire supply, then to use spare LEGO Technic beams & friction pins. After fumbling through bags of wire, pulling what I need out, and stuffing it back into the bag, I decide to take a stance and make a change!!!! Digging into my Mindstorms / Technic supply, I pulled out some beams and friction pins. 15 minutes later, I have a nice storage solution for my silcone wiring.…
LEGO – Turbo
My son likes to build mini robots and other characters out of LEGO. A while back, he made me Turbo. Cool.
Prop Storage Using LEGO Technic Axles
I have a variety of 5040 and 5030 spare props. The need for both CW and CCW props, makes for a mess when trying to find a replacement when you crash and need a new prop. Given I break at least 1 prop per flight (I'm learning flips these days!), I wanted a quick way to access either size or direction of prop. Look no further to your LEGO Technic collection for axles (or…
Quad Landing Gear Meets LEGO Shocks
After a few hard landings, the carbon fibre landing gear that came with the ZMR250 frame were done. After researching different solutions, I gave the zip tie concept a try. The solution entailed creating 'loops' out of zip ties and mounting them to the quad legs. However, they sagged under the weight of the quad only a day or so after mounting them. This caused the quad to be out of level - not a good thing for…
