    #726 – Arduino’s Invisible Touch with Massimo Banzi

    17.06.2026 | 1 Std. 10 Min.
    Welcome, Massimo Banzi of SuperModerno and co-founder of Arduino

    Introduction and SuperModerno: Massimo introduces himself as a “friendly nerd” and discusses his new project, SuperModerno

    The project aims to explain the “behind the scenes” of technology to prevent people from becoming “slaves to the platform”

    The History of Technology: Massimo expresses his passion for technology’s history, emphasizing non-American innovators to show Europeans they can also lead in technology, citing the UK-based origins of the Arm processor

    The Legacy of Olivetti: He highlights Olivetti (founded in 1908), which moved from typewriters to creating the Programma 101, the first desktop computer used by NASA to compute orbits for the Apollo program

    Design as a Differentiator: Olivetti was the first tech company to apply design to everything (products, posters, and architecture)

    This inspired Massimo’s concept of the “invisible touch”, the idea that consistent, intentional design creates a unique connection with users and gives a company a competitive edge

    The Interaction Design Institute Ivrea (IDII): Massimo’s path led him to IDII, located in the former Olivetti research building, where he transitioned from a two-week sabbatical to a four-year stay

    Learning by Making: To help students with no electronics background, Massimo drew on how he learned as a seven-year-old (“learning by making”) to remove the friction of interacting with technology

    The Founding Team: He met Tom Igoe (ITP) and David Cuartielles, and they realized students were afraid to be creative because they feared “blowing up” expensive tools like the Basic Stamp

    The “Pizza and a Beer” Price Point: Massimo aimed for a hardware cost of 20 Euros, roughly what a student would spend on a pizza and a beer, to encourage experimentation

    Building the Platform: Along with David Mellis, the team adapted Processing (a language for artists) by “surgically” replacing Java with C++ to create the Arduino IDE

    Ivrea Manufacturing: Leveraging the industrial base of Ivrea and Torino (the “Detroit of Italy”), Massimo was able to find local PCB manufacturers and assemblers just a short drive away

    From Hacking to AVR: Massimo’s early work involved hacking satellite TV PIC chips for soccer fans, but mentor Bill Verplank encouraged him to use AVR microcontrollers because they could be programmed simply in C

    Enabling Creators: Massimo shares stories of how Arduino enabled others, such as Josef Prusa, who started with Arduino as a teenager before building his global open-source 3D printer company

    The Innovation of Simplicity: Massimo argues that Arduino’s true innovation is the user experience

    This is measured by the “Time to First Blink”, the goal for a user to go from downloading software to blinking an LED in five minutes

    Standardization and “The Core”: Arduino became an ad-hoc standard by providing a compatibility layer across different microcontrollers

    Massimo believes in having a “small slice of a really large pie” by allowing other architectures to work within the ecosystem

    Hardware Architecture and the “Lasagna”: Inspired by the PC104 format, the board uses a layered approach where modules stack like a lasagna

    The “Shield of a King”: The name Arduino comes from King Arduino of Ivrea; David Cuartielles suggested that since the board was named after a king, the add-on modules should be called “Shields”

    Hardware Design Choices: The board fits a credit card size (to stay within the free version of Eagle software) and is blue because that color was thought to be less tiring for workers’ eyes

    Happy Accidents: The unique shape was chosen to be “ourselves instead of everyone else”

    During the design process, Massimo inadvertently moved a connector by half a step, creating an offset header that they kept for consistency after the first few thousand were made

    The Discovery of Auto-Reset: During a workshop in Germany, Massimo solved the frustration of manual resets by soldering a capacitor to the DTR pin, allowing the software to trigger the reset automatically

    The US Market and Legal Battles: Tom Igoe’s adoption of Arduino at NYU helped the US become the project’s single biggest market

    This growth led to a difficult legal battle for control of the brand against a former partner

    Support from Arm: Massimo credits Arm Ltd (and CEO Simon Segars) for providing the strategic support that allowed the founders to regain control of the company. Massimo believes this is the first time he has talked about the role of Arm in the difficult legal process.

    Industrial and AI Expansion: Partnerships with Intel and Microsoft (Windows 10 IoT) led to early forays into TinyML (AI on small boards) back in 2017

    The Qualcomm Acquisition: In October 2025, Qualcomm acquired Arduino, which Massimo sees as essential for bringing “advanced silicon” into the family to handle the increasing complexity of technology

    The “Arduino Formula” and Layering: Massimo views Arduino as a formula for simplification that can be applied to anything, including complex Linux machines like the Uno Q

    This is achieved by building in layers, where beginners use high-level abstractions and experts can “strip away” layers to reach the bare metal

    The Future Vision: Massimo looks forward to the “Arduino Formula” being applied to new fields, stating he is waiting for someone to develop an “Arduino for biology” using CRISPR and DNA technology

    #725 – The Secret Life of Circuits with lcamtuf / Michał Zalewski

    04.06.2026 | 59 Min.
    Welcome Michał Zalewski, AKA lcamtuf!

    The lcamtuf Substack is where Michał is writing most these days

    Chris first found and geeked out about the CNC guide on the lcamtuf original site (discussed many times here)

    Michał is interested in the craft of teaching electronics

    He recently published The Secret Life of Circuits with No Starch Press

    Use the code AMPHOUR26 for 30% off The Secret Life of Circuits valid from June 1st through June 30th

    It was announced on his blog here

    Deriving fomulas from basic trigonometry sometimes bugs people who think electronics should only work with calculus

    Software geeks follow the site, often getting lots of attention on Hacker News

    Row hammer DRAM

    There were no Information Security degrees in the early days, so the field was made up of folks with backgrounds in math and EEs

    Fuzzing for security

    SMBC cartoon for blming humans

    Books

    American Fuzzy Lop

    The Tangled Web

    P0f v3

    Silence on the Wire

    Security stuff (including books on the subject) ages over time, as opposed to electronics

    On the subjects of Calculators (and Michał’s collection)

    Calculators are a footnote in the history of computing, but still intriguing

    Dead ends in calculators

    CRT displays on calculators

    Nixie tubes

    Discrete moving into logic gates into processors

    Mechanical calculators are rare and get a high price online

    Working with transistors

    The Secret Life of Circuits start with FET based transistors vs BJT

    BJTs are often right after diode chapter because of the multiple junctions in an NPN, but that doesn’t make it easier to understand

    Projects

    A recent project involved making a clock out of current meters 

    Woodworking and AI example

    PCBs we are used to ordering at low cost (JLC, PCBway, etc) are normally loss leaders to get larger business later

    Chris found his low cost microscope from Florin/Voltlog trinocular video 

    lcamtuf will be on the show soon, Chris bought a CNC mill because of a single webpage of his making

    TagMod board is a new breakout Chris made for injecting power through a 10 pin TagConnect cable.

    NXP devboards somehow have LEDs as bright as the sun

    Dave has been revisiting his solar analytics (update: he figured out he’s getting charged more too!)

    Chris has been working at Canonical (makers of Ubuntu, new owners of Golioth) for a few months now. That was the trip to Spain.

    Dogfooding your own product

    Chris created a backronym: “Application Level Program Optimization” or… ALPO

    Chris built a new vibe coded project for talking to Zephyr devices using Web Serial and passing firmware packages over SMP

    CI/CD

    Debian now requires “fully reproducable” builds to harden against supply chain attacks
