Eight years after 2,154 backers soldered together the original DIY phone, CircuitMess returns with a sequel anyone can assemble in about two hours — and program in plain English, Python, or C++.
Middletown, Delaware, USA — September 10th, 2026 — CircuitMess today launched its Kickstarter campaign for MAKERphone 2.0, a fully functional 4G mobile phone that arrives in pieces. Builders assemble it themselves in about two hours — no soldering and no experience required — insert a nano-SIM, and it makes real calls and sends real texts on live cellular networks. Then comes the part no other phone offers: its owner programs it, starting by describing ideas in plain English in VibeBoy, CircuitMess’s AI-assisted coding studio, and progressing to real Python and C++.
From Seven Hours of Soldering to a Two-Hour Build
The original MAKERphone, launched on Kickstarter in 2018, asked backers to spend roughly seven hours with a soldering iron — and 2,154 of them did. Eight years and feedback from more than 6,000 MAKERphone users later, MAKERphone 2.0 keeps the build-it-yourself soul and removes the barriers: every component clicks, screws, or plugs into place, guided by a LEGO-style illustrated manual and video guides. Along the way, builders learn what a phone actually is from the inside out — the processor, the modem, the display, the battery.
A Phone With No Locked Doors
Assembled, MAKERphone 2.0 is a complete classic phone: calls, texting, contacts, ringtones, alarms, a music player, and more than 10 built-in retro games on a 1.77-inch color display — 104 grams of open, hackable hardware built around the Arduino-compatible ESP32-S3. Its UMAX expansion port takes six snap-on modules — Camera, Big Speaker, Flashlight, Environment, Infrared, and a DIY Perf Board for custom circuits — each auto-detected the moment it is plugged in. An optional companion, the buildable MAKERband smartwatch, pairs with the MAKERphone as well as iOS and Android, with 15 watchfaces, five mini-games, and phone notifications.
For parents, it is a first phone that calls and texts the people a child needs — with no social media, no app store, and no infinite feed. When a kid wants a new app, they build it.
Coding That Starts in Plain English
MAKERphone 2.0 is programmed through VibeBoy, CircuitMess’s AI-assisted coding studio: describe an idea in plain English — „make me a game where a taco dodges falling pickles“ — watch AI write the code, and send it to the phone in one click. Then open that code, learn to read it, fix it, and make it your own: a four-level learning ladder takes builders from Pixel Rookie (ages 9+) to Vibe Coder, writing their own Python and C++ from a blank file. VibeBoy is not autocomplete — it teaches users how to think with AI: how to describe problems, read generated code, and correct it when it is wrong. Every MAKERphone 2.0 comes with three months of unlimited AI usage and a free VibeBoy tier for life.
The philosophy behind the product: MAKERphone 2.0 doesn’t fight screen time — it turns it into create time.
„The original MAKERphone taught thousands of kids that a phone isn’t magic — it’s parts and code, and both can be mastered,“ says Albert Gajšak, founder and CEO of CircuitMess. „MAKERphone 2.0 takes away everything that used to stand in the way. You build it in an afternoon, and with VibeBoy you can make it do things no phone in any store can do — even if you have never written a line of code.“
Ready for Manufacturing, Not a Prototype
MAKERphone 2.0’s hardware design is complete and final production hardware exists; the software is feature-complete and in final testing. The Kickstarter campaign funds manufacturing at scale, not R&D, and deliveries to backers are expected in Q3 2027. The campaign offers backers exclusive early-bird pricing and limited launch rewards.
