Editor of Brick by Brick, adult LEGO fan and collector
I'm Jonny Utah, the editor behind Brick by Brick. I'm an adult LEGO fan who built this site to answer the questions I kept running into as a collector: which set is worth the money, whether a retiring set is likely to hold its value, and what to buy for someone else.
Every guide and comparison here starts from the same sources: our catalog of official sets for piece counts, years and inventories; current market pricing; and community feedback from Reddit and YouTube. Where a page uses AI-assisted summaries it says so, and the numbers on it come from that data, not from the model. I don't build every set I write about, and the site never claims otherwise. When an article draws on hands-on experience with a set, it says so in the text.
I also build the tools on this site, from BlockTalk to the price-per-piece and display-space calculators, because I wanted them for my own collection. The full methodology is on the How We Review page.

A LEGO sorter is a feeder, a camera, a classifier and a gate. This guide builds each part with a Raspberry Pi, the Build HAT and OpenCV, with working code for capture, detection, colour and shape features, a trained model or the Brickognize recognition API, and the sorting gate.
How to control LEGO Powered Up hubs from an ESP32 with the Legoino library, which versions still compile, and working code for train motors, Technic angular motors, sensors, battery level, hub emulation and Power Functions infrared.
A jammed Great Ball Contraption module keeps its motor stalled, drawing current and making heat. Three layers stop that, from simplest to most capable, a slip clutch in the drive, an Arduino watchdog that cuts power when current is high and the shaft has stopped, and, for Powered Up motors, a Pybricks program that checks for a stall.
The Raspberry Pi Build HAT drives LEGO Technic and SPIKE motors and reads SPIKE sensors from Python. This guide covers what it works with, the power it needs, the serial setup people miss, and working code for motors, motor pairs and sensors.
LEGO gift ideas sorted by occasion, from a child's birthday and Christmas to Halloween, Valentine's Day, Mother's and Father's Day, a housewarming, a new desk and a small thank-you, using only sets our catalog lists as still sold new.
How to arrange LEGO Botanicals sets into an indoor garden that looks deliberate, from grouping by height and choosing which sets need a vase to light, dust and pets, using sets still sold new and noting the two that leave at the end of 2026.
For LEGO enthusiasts and collectors, the allure of vintage sets is undeniable. These sets not only represent a piece of LEGO history but can also be valuable additions to any collection. This guide...
How the LEGO color palette grew from a handful of bright colors on the first 1949 bricks to dozens today, why the greys and brown changed in 2004, and which colors make up most of the pieces in 2026 sets, counted from our catalog.
How to photograph LEGO models well with a phone or a camera, soft light, a clean backdrop, steady support and a little editing, plus how to build a scene around a MOC with current LEGO sets.
The cheapest LEGO storage is the containers you already own. Clear tubs for loose bricks sorted into a few broad groups, a divided box for small parts and minifigures, and labelled bags to keep sets together go a long way before you need to buy furniture.
How LEGO themes evolved from DUPLO and the 1978 minifigure themes Town, Castle and Space, through Star Wars and Harry Potter, to the adult lines Architecture, Icons and Botanicals, with the year each began and the biggest themes in 2026.
Which IKEA shelves and glass cabinets suit a LEGO display, with the sizes and shelf loads IKEA publishes, what replaced the DETOLF, how to light a cabinet and why every one must be anchored.
