Tinkered AI

This is what day one looks like. First electronics project ever, built with Tinkered. #Arduino #hardware

@Joeltrevino15 @Joeltrevino15 thanks for flagging. We pushed a fix. Should be working now.

@TinkeredAI Mine won’t let me open a folder for a project

@oprydai Mercury retrograde

what's stopping you from building hardware like this?

@Afghan_Engineer That’s awesome getting a BLDC spinning on a breadboard is no joke, especially with forced commutation. Respect.

Built a simple BLDC motor driver on a breadboard for a RoboCup Junior soccer robot. It uses forced commutation with a microcontroller and 9V battery, but the performance is low due to weak parts. Not perfect but the motor still spins nicely.

@hdiv6xeWxcLUS51 That’s really cool 🔥 love the upgrade with more buttons and the new design!

ESP32と赤外線LEDを使ってテレビのリモコンを複製してみました。前回と比べてボタンを増やしてデザインも変更しました。

@RoundtableSpace Building Tinkered today. Working on making it way easier to go from an idea to a working hardware project without all the setup pain. Big shoutout to all the builders out there, we got this!

WHAT ARE YOU BUILDING TODAY?

@sozoraemon This is honestly the best kind of project, just building for the fun of it. The adjustable range and distance from home is actually pretty cool too, even if it’s just for you, great job!

Raspberry Piで作ったGPSレーダー。横のボタンでレーダーのレンジを変更できるようにしました。自宅との距離を常時表示できます。特に意味はないけど、自己満足ガジェットです。

@Zinny_Edmund Software is still evolving, but the physical world is where a lot of the next building is happening. Hardware - sensors, devices, infrastructure...there’s still so much to create....

Quick question: If everything in software is already built… what are we supposed to build??

@Ogooluwadotun Keep going, you’re building a strong base 💪

3 concepts. 1 build. 0 AI assistance. → LED blink with millis (no delay) → PWM dimming controlled by a potentiometer → Blink speed controlled by a potentiometer Coded everything from scratch. Small win, but it's mine 🫡 Onto the next

@0xfishylosopher @rishi____1 This is insanely cool, baremetal + secure elements is a different level🔥!! Also says a lot that the hardest part wasn’t crypto but just getting the chip to wake up 😅 this is exactly the kind of friction we’re trying to remove with Tinkered.

How can you build a baremetal Trusted Execution Environment (TEE) with $5 hardware and a Raspberry Pi? For Stanford's CS 140E: Embedded Operating Systems final project, @rishi____1 and I built a simple implementation of a TEE-like environment on a Raspberry Pi using a trusted hardware chip, similar to hardware wallets like Ledger or Trezor. We used the ATECC608A secure element, a widely available trusted hardware chip to do keygen, sign, and verify transactions for a baremetal Raspberry Pi (BCM2835). The ATECC608A chip cost about $5 each, whereas a typical hardware wallet can cost $100 or more. Over the course of a week we: - Implemented baremetal I2C protocol for the Pi - Wrote ATECC608A drivers for ECDSA keygen, sign, verify based on just a datasheet - Basic hardware key encumbrance, with private key stored on the trust hardware chip, public key available on request - Implemented a supplemental Arduino ATECC608A I2C slave simulator for testing I2C communication that uses micro-ecc library with secp256k1 curve (aka Bitcoin curve) Some challenges faced: - Secure chips are badly documented, even gathering datasheets and making sure they're consistent with observed behaviour took a long time - Surprisingly, getting the chip to wake up on baremetal code turned out to be the most time-consuming task (you have to send a specific signal on SDA line for a specific time duration, then read immediately) - Unfortunately, the ATECC608A secure chip only has documentation for the NIST P256 elliptic curve, rather than the secp256k1 curve, so we only implemented support for P256 on the ATECC. For secp256k1 support, we wrote a proof-of-concept on an Arduino I2C slave simulator using the micro-ecc library. But overall, it was insanely cool to combine cryptography with embedded systems and build a hardware TEE-like environment on baremetal! [GITHUB LINK BELOW]

@yacineMTB Agreed lol. Best of luck, we got this!⚡️

Doing a hardware startup has been the education of a lifetime

@willreil Let’s gooo, that’s a real smart home stack now. This is exactly the kind of project we’re building Tinkered for: go from microcontroller idea to wiring, code, and simulation before touching the hardware.

My office lights are now controlled with an ESP32. The antenna on this thing sucks so it has connectivity issues but the concept is working!

@playwithcircuit Simple setups like this are the best way to learn. Now imagine going from idea to working setup like this in seconds, that’s what we’re building with Tinkered.

Measure temperature with Arduino—no complex protocols needed. Use LM35: • Analog output (°C) • Easy interfacing • Real-time LCD display Perfect for monitoring systems. Read 👇 playwithcircuit.com/lm35-temperatu…

@IlirAliu_ Love this, such a clean way to understand sensing.

You don’t need expensive hardware to build something that feels like real robotics. An Arduino, a servo, and an ultrasonic sensor can scan space and turn echoes into a simple radar view. It sweeps, measures distance, and visualizes it in real time. Cheap, simple, and a solid way to understand how machines sense the world. Limits show up fast, which is where better sensing and smarter software come in. Original build by SunFounder youtube.com/shorts/3v23xd9… —— Weekly robotics and AI insights.

@LenaWithAI @oliviscusAI Try us 😎 your board won't burn but your project will be fire! tinkered.ai

@oliviscusAI bet it just hallucinates a circuit that burns your board before you even plug in the usb also free tools rarely include a refund for the smoke damage

Someone just built a Claude Code for electronics. It's called Blueprint. Type what you want to build and it generates wiring diagrams, bills of materials, and step-by-step assembly guides for your Arduino or Raspberry Pi project. 100% Free.

If you like this, you can sign up for free and start testing it yourself 👉 tinkered.ai

This is awesome 🤯 love seeing projects like this still inspiring years later. If you’re into building things like this, we’re working on something you might enjoy at Tinkered - you can describe a project in plain English and instantly get the wiring, code, and a working simulation before touching any hardware. Makes turning ideas into real builds way faster (and way more fun): tinkered.ai Would love to see this recreated or improved with it 👀

Here's a free PCB-robot design I made 3 years ago (🤯)

Who wants to build cool hardware? ⚡️ With Tinkered, you just describe what you want and get the wiring, code, and 3D simulation instantly. No complexity. Just build. Start here → tinkered.ai

This is exactly the problem we’re solving. Hardware shouldn’t take weeks of datasheets and debugging. With Tinkered, you just describe what you want → get wiring, code, and a working simulation instantly. We just launched our beta: auth.tinkered.ai/sign-up Curious to hear what you’d build 👀

llmfit. Useful tool that probes hardware and tells you exactly which LLMs will actually run. - handles MoE expert offloading, picks the best quantization for your RAM, estimates tokens/sec before you even pull the weights. Essential for local dev. github.com/AlexsJones/llm…
