Guides published sep 1, 2026
In this guide, you will learn which hardware devices are good for AI tinkering and which one is right for you. We cover what each option is good for and which one we’d recommend for most people.
By the end, you will have a simple way to choose between an ESP32, Raspberry Pi, and dedicated Mac based on your time, budget, and what you actually want to build.
Whatever you buy, copy the product link into ChatGPT and tell it what you want to build. Ask it to help with setup, code, and troubleshooting. You can start with this prompt:
I am setting up [DEVICE] for [FIRST PROJECT].
Help me identify the required power, storage, cooling, cables, and software. Then give me one setup step at a time. Use the documentation for this exact model, explain how to verify each step, and stop when you need information from the device or from me.Keep it focused on the exact model in front of you. When something works, save the commands and fixes so you do not have to solve the same problem twice.
Before you compare specs, answer three questions.
Those three answers do most of the work. Now we can look at what each device is actually good for.
An ESP32 is basically a simple IoT device that usually has a pretty screen or an OLED touch screen. It can connect over Wi-Fi or Bluetooth and control buttons, microphones, lights, sensors, and other physical parts. It is not a normal computer, so the AI work usually happens through a cloud service or a stronger computer while the ESP32 handles the interface.
We tested a Waveshare ESP32-S3 4.3-inch LCD board as the main example. We also looked at a much smaller touch-screen device with physical buttons. These boards make sense for projects such as:
Choose an ESP32 when the project has one clear job. The limitations are part of the fun. You have to pick one thing, which makes it much easier to finish.
Our favorite option is the Raspberry Pi. It is a real Linux computer with a file system and a desktop, but you can also run it headlessly and connect from another computer. You get a lot of bang for your buck, especially for agents, dashboards, local network services, cameras, and home automation that need to stay on.
We run two or three Hermes agents on an 8 GB Raspberry Pi 4. It has stayed up for months, and it also connects to a 3D printer. Because it lives on the home network, it keeps working without tying up a daily laptop.
The Raspberry Pi Zero W we showed is much more limited. Treat small Zero models as an option for lightweight services and simple hardware projects. For a general always-on AI server, use a more capable Pi with enough memory for the job.
The $350 listing in the screenshot is a retailer price, not official Raspberry Pi pricing. Check the current board price on the Raspberry Pi website before you buy.
Pro tip: Budget for the full setup, not only the board. Storage, power, cooling, a case, and cables can change the real cost.
You may need:
The tradeoff is tinkering. If an agent stops, you may need to connect through the terminal, inspect the service remotely, or power-cycle the device. It takes more work than opening a laptop, but that is exactly why you learn so much from a Pi.
Move up to a Mac when you want serious local AI or a full computer for coding agents, creative apps, and daily work. You do not need to start here.
A MacBook gives you a built-in screen and keyboard, so it is easier to open and troubleshoot anywhere. A Mac mini makes more sense when the device will stay at a desk and run as a permanent workstation or server. Remember to include the display, keyboard, and mouse when you compare the total setup.
We used a MacBook Neo for Codex projects and Hermes agents. We also accessed Grok Bot from it, but Grok Bot keeps working on a persistent cloud computer rather than using the Mac as its dedicated compute.
An 8 GB MacBook Neo can get slow when Codex, another agent, and many browser tabs are open together. Memory matters if you plan to run several agents or local models at the same time. Check the requirements for the specific model and apps you want to use before choosing a configuration.
A dedicated Mac also keeps all of this tinkering off your real work computer. You can play with agent permissions, terminal changes, and test accounts without worrying that an agent will touch your private files or break the machine you use every day. You still need sensible account, permission, remote-access, and backup rules.
Here is the simple version:
| Choose | When it fits |
|---|---|
| ESP32 | You want an afternoon project, have less than $50 to spend, and want to build one focused gadget. |
| Raspberry Pi | You want a weekend project, have less than $300 to spend, or want an always-on OpenClaw or Hermes Agent. |
| Mac | You can spend $500+, want serious local AI, or need a computer separate from your work laptop. Pick a MacBook Neo for portability or a Mac mini for your desk. |
For most people, we would start with the cheapest Raspberry Pi we can find. Learn the setup, ask ChatGPT for help, and upgrade once you know exactly what you need. Go with an ESP32 if you already have one small gadget in mind. Go with a Mac if you need serious local performance or want to keep agent work off your main computer.
