Nerdy hobbies for adults: four projects you can finish at home

There's a particular kind of evening where you've watched everything, scrolled everything, and somehow ended up reading about a 1970s bus depot. I'd take that as a cue to make something. These four hobbies fit on a table, give you a first project with an actual finish line, and let you decide whether you want to go deeper afterwards.

Card models are for people who notice buildings. Miniature painting is for anyone who likes colour and tiny details. Book arts turn a stack of paper into something useful. Pico electronics make a light respond to code you've written. I'd pick the one whose process looks fun, not the one with the most impressive finished objects online.

Which one suits your evenings?

Card models: build one place, not a whole railway

A card kit starts as printed, pre-cut pieces that you fold and glue into a building. Metcalfe ModelsMetcalfe ModelsA UK maker and direct retailer of pre-cut card building kits, scenery and modelling materials in 00/H0 and N scales.Buying guide · View store → makes railway scenery, but you don't need track or a spare room to enjoy building one structure for a shelf. Its PO316 Little Cardleywick station shelter is a 00/H0 scale example with a small footprint. The product page has a footprint sheet and kit instructions you can inspect before buying. Pick PO316, rather than the smaller PN916 N scale version, if you want the pictured kit.

The pleasure here is getting walls, windows and roof edges to meet neatly. It's also the frustration: this is for someone who enjoys taking their time over small parts. Read the instructions first and budget for a cutting surface, suitable glue and a sharp blade if you don't have them. Our card model beginner guide goes further into tools and choosing a first kit.

Want to judge the size before committing? Budget Model Railways' 2025 review shows the PO316 shelter itself. World of Railways' 2020 build uses a different Metcalfe signal-box kit, so watch that one for the folding and assembly process rather than the final shelter.

Miniature painting: paint one figure before buying an army

You can like painting miniatures without wanting to play a tabletop game. A single figure gives you a contained experiment in colour, brush control and when to stop. If you've never held a tiny model, Warhammer's store finder is a sensible first stop: its shops offer an introductory miniature and help with building and painting. Contact the branch to arrange a visit.

If you want to try it at home, the Space Marines: Infernus Marines + Paints Set is a specific, modest option: three push-fit figures, paints and a brush. Its blue Ultramarines colour scheme is part of the choice; if those characters don't appeal, pick a figure you actually want to look at. The Warhammer Colour tutorial follows that very set. Check the retailer's current contents before ordering, and allow for a workspace and any extra tools you want to use.

Watch the Warhammer 2023 set tutorial if you want to see what its colours can do. Duncan Rhodes' 2024 first-miniature lesson spends longer on the general painting process, but uses a different selection of paints: it's a technique guide, not an instruction sheet for this box.

A first Warhammer shop session often raises the next question: how much do you actually need to buy? This r/minipainting beginner discussion starts there, with different painters describing their own routes in.

If you discover you enjoy the painting more than the game, that's a perfectly good answer. Buy another figure when you know what part of this one you liked.

Book arts: make a booklet you can fill

Start with a single-section booklet: fold a few sheets, add a cover, then stitch them through the fold. It could hold a short photo story, recipes or a tiny field guide to your neighbourhood. The first decision is whether you want to learn with someone or make one at home.

For a taught route, the London Centre for Book ArtsLondon Centre for Book ArtsA London book-arts studio selling workshops, studio access, tools and gift cards for bookbinding and printmaking.Buying guide · View store → lists bookbinding and printing workshops. Choose a class by the object you'll leave with, its experience level, and whether materials are included. If London is too far, use those questions when comparing a local class. A workshop gives you tools and a tutor for a first attempt; buying a tool kit makes more sense once you know you enjoy the work.

For home practice, Sea Lemon's 2020 single-section booklet video shows several ways to stitch one folded section. Start with the simple saddle stitch rather than treating all eight patterns as a shopping list. The London Centre for Book Arts beginner tool kit has an awl, folder, knife, brush, needles and thread, but doesn't include paper or cover material. You can try folding a booklet with paper you already own before deciding you need the specialist tools.

One r/bookbinding commenter suggests using a ream of ordinary printer paper to practise before deciding whether to buy specialist long-grain paper. That's a practical way to find out whether you enjoy the folding and stitching itself.

Pico electronics: make a light obey your code

A Raspberry PiRaspberry PiRaspberry Pi's official product catalogue and approved-reseller route for computers, microcontrollers and accessories.Buying guide · View store → Pico is a microcontroller: it runs a small program that reads inputs and controls outputs. It isn't a tiny desktop computer. For the simplest physical result, connect an LED and change its blinking pattern in MicroPython. You can see immediately whether the code and wiring agree.

The Raspberry Pi Foundation's Pico introduction moves from LEDs to buttons, buzzers and dials. Check each project's parts list; those later projects need components beyond an LED. The Pi Hut's starter kit is a better first purchase than a bare board if you own none of the parts. It contains a Pico H with pre-soldered headers, a micro-USB cable, breadboard, wires, LEDs and resistors, plus a getting-started guide. That covers a basic LED build without soldering; it isn't a complete kit for every project in the Foundation pathway.

Core Electronics' 2021 video shows how to set up a Pico in Thonny and write an initial MicroPython script. It uses the original Pico board, while the kit includes a Pico H with headers; the programming introduction is the relevant part. If you're looking for an evening away from a screen, choose paper, card or paint instead. If you like diagnosing why a wire or line of code isn't doing what you expected, Pico is probably the most absorbing of the four.

What should you buy first?

I'd keep the first purchase tied to a first finish. For card models, look at the instructions and add the basic tools you lack. For painting, try a shop session or a figure-and-paint set before a large army box. For book arts, fold a booklet with your own paper or book a class before buying specialist tools. For Pico, follow one project and check every component against its parts list.

The object is to find out whether you enjoy doing the hobby. A finished shelter, figure, booklet or blinking LED gives you that answer more honestly than a cupboard full of supplies. And if you're buying for someone else, our Christmas guide for nerdy adults starts with whether they'd prefer a class, a complete project or materials for a hobby they already have.
