It’s a bummer… but it was a MAJOR update from Tesla’s Q1 2026 earnings call today with Elon confirming that Hardware 3 will not be able to achieve Unsupervised FSD. “Unfortunately, Hardware 3, I wish it were otherwise, but Hardware 3 simply does not have the capabilities to achieve Unsupervised FSD. You know, we did think at one point it would have that, but relative to hardware, it has only 1/8 of the memory bandwidth of Hardware 4, and memory bandwidth is one of the key elements needed for Unsupervised FSD.” Tesla plans to fix it for customers who bought FSD by: A) Discounted trade-in toward a vehicle with full Hardware 4 OR B) Direct upgrade by replacing the HW3 computer and the cameras to bring the car to HW4 spec To make upgrades fast and scalable, Elon also told us that: “…we’re going to have to set up like, kind of microfactories or small factories in major metropolitan areas… So we basically need like many production lines to make the change.” He also said over time it makes sense to convert all HW3 cars to HW4 bc this is what will enable them to enter the Robotaxi fleet and have Unsupervised FSD. Sorry for HW3 Tesla owners… but thanks for the update Elon.

This robot assistant from the NVIDIA CES Keynote on Monday is going viral. Nader Khalil🍊 explains all the hottest emerging AI trends in one demo: AI applications in 2026 will be multi-model, multi-modal, hybrid cloud/local, use open source models as well as proprietary models, control robots and embedded devices in the physical world, and have voice interfaces. (And the demo had a cute robot *and* a cute dog. Gold.) The demo was built with Pipecat AI. NVIDIA posted a really nice technical walk-through and complete code. The Reachy Mini robot from Hugging Face is open source hardware. (You can order it now, I have one!). You can run the assistant locally on your own hardware, in the cloud, or both.

This video is from an old Coldcard tutorial showcasing dice rolls to add entropy. If you have no other hardware to migrate to but are worried about being on a hot wallet until you find a replacement device, this is just one of many possible options for the time being. A few things: 1. It is important to upgrade to the newest firmware that was released today at the following link: 2. Even with updated firmware, I think it's prudent to utilize dice rolls upon seed creation as seen below. 3. Nathan Bitcoin Mentor will be dropping a video shortly showing how to utilize seed vault to migrate from one seed to another on a single device. He'll reply with it here after. 4. If you have access to other hardware, the above is moot and you should simply migrate to that. This is time sensitive and waiting is not an option.

Building AI agents and tools is getting ridiculously easy! Here is a pretty impressive FREE and Open-Source AI agent builder that runs on your computer. It's a desktop app you can install on Mac or Windows. Link: • Free • 100% no-code: You can type what you want, and the tool will build everything for you. • You can use local models like DeepSeek or Qwen, or connect to cloud models like GPT-4o, Claude, or Gemini with your API key. • You can turn the tools you build into MCP Servers. I recorded a quick video to show you how easy it is to build something from scratch.

People don’t realize this yet… 😅 You can literally build your own private crypto savings account with full self-custody. Here’s exactly how with ZKX Wallet | The Secure and Private Wallet 🗽 🧵 1/ Create a ZKX wallet using a Trezor hardware device for maximum security. 2/ Set up 2 passphrase-protected wallets inside it (one for active use, one for long-term holding). 3/ Connect both to the ZKX Wallet app. 4/ Shield your funds into the first wallet (Railgun Private Mode → 0zk address). 5/ Privately transfer them to the second wallet for long-term holding. Now you have a seed + passphrase-protected private savings setup that’s invisible on-chain 💪 6/ Need to spend or move funds? Simply unshield to any public Ethereum or PulseChain address. 7/ Easily fund it with PLS, ETH, or other assets via Liberty Swap | C.R.O.P.S. on PulseChain 🗽 (public or private routes available).

YOUR HARDWARE WALLET SUCKS. PERIOD. ZachXBT just said what we've known for years: hardware wallets are garbage. We won't go as far but we surely feel they are not for everyone. They are for advanced users and by no means for wallets that are meant to be accessed frequently. There is one thing hardware wallets are good at: that is keeping crypto secure if someone physically trying to rip private keys (those that give you access to crypto) out of the chip. The reality is that attack almost never happens!😀 When it comes to the attacks that actually drain wallets, hardware wallets make them worse: >> 1. NOT DISCREETE The moment someone sees that little device, you're a confirmed high-value target. >> 2. LEAKED EMAILS AND ADDRESSES Buying one doxxed thousands of people. Leaked customer databases with the real names and home addresses. You just joined a phishing hit list. Emails targeting hardware wallet owners are now so convincing that even veterans get fooled. Privacy can't fail harder than that. >> 3. PAPER BACKUPS You still write your keys on paper. The seed phrase backup negates the entire point of the device. BTW, mobile wallets already moved on: Unstoppable now has passkey wallets allowing to create and restore with zero seed phrase, secured by your device. That will likely become the golden standard in the future. >> 4. YOUR PHONE ALREADY HAS A VAULT Your phone is designed for security. There's a state of the art secure storage chips in your pocket already. Apple and Google built isolated secure elements to guard the most sensitive data in your life. If integrated right by the devs, it's the most battle-tested security hardware on earth. >> 5. MOBILE APP = DISCREETE Nobody knows you're carrying a vault. A phone is the most discreet way to hold crypto. >> 6. MOBILE APPS CAN BUILT CREATIVE SECURITY FEATURES The mobile OS allows many possibilities for secure use. Hardware wallets are meant to stay primitive by design and therefore can't ship security features that are are needed. - Your wallet can wear a disguise. Some wallet apps look like calculators. - Unstoppable's Duress Mode gives you unlimited unlock PINs - under coercion, you show a decoy and keep the rest invisible. - Unstoppable's phishing protection catches look-alike addresses before you send - blocking the #1 way people actually lose crypto today. Hardware wallets solved 2015's problem. Your phone solves 2026's. MOBILE WALLETS ARE THE FUTURE!

Looking for a last minute gift for your kids, your nieces, nephews, whatever… Here’s how to give them the gift of Bitcoin. When I was a kid, my aunts and uncles gave me Treasury bonds. But my parents had to hold them, nobody remembered where they went, and of course… they ended up being basically worthless. But giving Bitcoin isn’t that easy either… here’s the issue with Bitcoin gifts: 1. Kids under 18 can’t legally have a River or Swan account. 2. Hardware wallets are like a hundred bucks, so that makes no sense if you’re giving less than that. 3. And little kids don’t even have phones. So here’s what I did instead. STEP 1 I downloaded a basic Bitcoin wallet app and created a separate wallet for each kid. STEP 2 I sent about $50 of Bitcoin into each one. STEP 3 Each wallet has its own seed phrase. I printed it out and the. I gave one copy to the parents, and I kept one backup. STEP 4 Then I printed the public address QR code, put it in a small picture frame, and hung it on their wall. So now they can scan it anytime and see their Bitcoin growing… but nobody can spend it. After that, I deleted the wallet app completely. The Bitcoin only exists via the seed phrase. And every birthday, Christmas, Easter or whenever… I can just send more Bitcoin to that same address. They watch it stack up for years.

Student from Hong Kong hacked Polymarket trading algorithm using Chinese AI model Qwen3-Coder. Almost $2,000,000 extracted in March. Zero drama with censorship, Claude token prices, or TOS. Pure GodMode from Chinese open-source AI. 4 wallets. $1.7M profit in 30 days. All trading the same crypto Up/Down markets. On-chain proofs: 1st wallet: 2nd wallet: 3rd wallet: 4th wallet: All wallets went live March 2. Same markets. Same insane logic. Meanwhile the rest of the timeline is crying trying to make censored Claude create something. Open-source code for a leading Chinese coding model was available online. It can be run for free - using your own hardware. Qwen3 on GitHub: Chinese LLM industry is about to make everyone seriously rethink AI prices and subscriptions. These wallets are perfect for reverse-engineering. Bonus: even your Claude can explain exactly how they work. Save the post or you’ll lose the wallet addresses.

“Why Seed Phrase Wallets Keep Getting Hacked — and What Comes Next” Most people think their cold wallet is safe. Most people are wrong. Soft wallets & hardware wallets that use seed phrase backups like Ledger, Trezor, Tangem etc. all have publicly known attack vectors. Let's break them down — without the marketing sugar. 1/ Ledger: Customer Database Breach (2020,) +272,000 full names, phone numbers, addresses leaked. Not the hardware — but the humans behind it. Result: phishing, extortion, SIM swaps…and fear. 2/ This was not a one-time slip. It permanently destroyed the idea that Ledger = privacy. 3/ Ledger Connect Kit Attack (2023) Hackers injected malicious code into Ledger’s JavaScript library. Thousands of dApps were affected. Yes — thousands. 4/ Cold wallet wasn’t hacked directly. But the supply chain was. That’s even worse. 5/ Ledger Nano S “Unhackable” Myth Researchers proved firmware could be replaced via MCU-level exploits. So much for “impossible to extract keys.” 6/ 2026 - Ledgers payment provider was hacked with all users data

Open source mining firmware + AI = unstoppable. ⚡ For years, people have tried to chase excess solar power with bitcoin miners. Stock firmware doesn't let you adjust power at all. Third-party firmware was too slow, some even restarted mining every time you changed the target. 256 Foundation & Ryan Kuester's Mujina just solved that. In this video: what I've been building with RY3T for their upcoming RY3T NOVA. ☀️ It tracks a power target anywhere from 1,000W to 3,000W, stepless, within seconds. Connect it to your inverter or smart home and turn excess solar into sats, instead of selling it back to the grid for pennies. NOVA scales to 1-3 miners, up to 9kW. 🔋 Learn more at (CH and EU currently - interested other places? let me know) A lot more coming in the next few weeks. Open source bitcoin mining hardware + software + AI is about to get very interesting. 🚀

FREE and open-source Bitcoin mining hardware: Don’t throw away or sell your S19j, S19k, or S19 Pro units just yet, developing something tailored for our Bitcoin-mining HeatHarvest greenhouse, semi-waterproof, moisture-resistant, and packed with some intriguing extras. Securing the hashboard with lock mechanisms was a priority, along with a tough and durable 3d printable frame that ties cleanly into other materials after printing. Working in mounts for alternative thermal-management modules, currently prototyping. Beyond the core functions, kept the pleb #Bitcoin miner in mind with this design, many pleb miners have small print area 3D printers, parts are kept within ranges to fit smaller printer beds. This is Prototype 1, the basic concept. Logged a dozen mod notes, now it’s back to CAD and reprints. Stay tuned, this is shaping up to be perfect for solo plebs mining at home and DIY Bitcoin heat capture projects.

Matthew Gallagher Built a $401M Company in Year One with 2 People. And the tool behind it? Claude Code. This year he's on track for $1.8B. Sam Altman predicted this. It's happening now. The problem? It costs money. API credits stack up. Monthly bills keep growing. Every prompt eats your budget. Every project drains your wallet faster. Until now. Two methods. 99% cheaper. One is completely free. Forever. $0. Not a trial. This video breaks down both step by step. ↓ Let me put this in perspective. $100-$500. That's monthly. That's what you spend. That's $6,000/year on API credits. Just to use a tool you haven't shipped anything with. The $401M guy? Spending $0. Same capability. Shipping weekly. Different cost structure. Different results. Different life. I'm about to hand you his cost structure for free. ↓ Open source vs closed source. Pay attention. Closed source: Claude. GPT-4. Pay per token. Meter always running. Open source: Qwen. Llama. Mistral. Free to download. Free to run. Free forever. No meter. No tokens. No bill. Here's what nobody tells you: 80% of coding tasks? Open source handles them. More than handles them. Writes clean code. Debugs errors. Generates boilerplate. Handles routine work perfectly. You're paying premium prices for tasks that don't need premium intelligence. That's hiring a brain surgeon to put on a bandaid. Smart play: Free models for the 80%. Paid credits for the 20%. That's what the $401M guy does. That's what this video teaches you. Follow Himanshu Kumar for more breakdowns that turn free tools into real businesses. ↓ Method 1: Ollama. Local. Free. Forever. Download it. Pull a model. Point Claude Code at it. Done. No internet needed. No API keys required. No monthly subscription. No token counting ever. No bill. Today. Tomorrow. Ever. Your data never leaves your computer. Complete privacy. Complete freedom. Claude Code thinks it's talking to the cloud. It's talking to your laptop. For $0. The video walks through every step: Every config file. Every variable. Every command. Every click. If you can follow a recipe, you can do this. People who set this up 3 months ago? Saved $300-$1,500 since then. Workflow didn't change one bit. ↓ Hardware you need: 16GB RAM: 7B models run smooth. 32GB RAM: 32B models run comfortable. 64GB + GPU: biggest models available. No GPU? Still works. Just slower. Few extra seconds. That's it. Your $1,500 laptop is sitting there running Chrome and Spotify. Put it to work saving you $200/month instead. Follow Himanshu Kumar for more breakdowns that turn free tools into real businesses. ↓ Method 2: Open Router. Free Cloud. No Hardware. Weak machine? Don't want local setup? This method is for you. Free AI models in the cloud. No download. No hardware. Configure Claude Code to route through Open Router. The config: Base URL: Open Router API. API key: free Open Router key. Default Sonnet: free. Default Opus: free. Default Haiku: free. Small fast model: free. Subagent model: free. Free. Free. Free. Free. Free across the board. Same interface. Same commands. Same workflow. Zero cost. Copy the config from the video. Paste it. Save $200/month. Starting today. Right now. ↓ When to use which: Ollama (local): Best for privacy. Best for offline work. Best for unlimited usage. Best if you have decent hardware. Open Router (cloud): Best for weak machines. Best for instant setup. Best for trying different models. Best if you don't want to manage anything. Both methods: Best for 80% of your daily work. Still use paid Claude for: Complex architecture. Multi-file refactoring. Deep reasoning tasks. The 20% that actually needs it. $20/month instead of $200/month. Same output. 90% less cost. ↓ The math that should make you angry. You (current): $200-$500/month. $2,400-$6,000/year. $7,200-$18,000 over 3 years. You (after this video): $20-$50/month. $240-$600/year. $720-$1,800 over 3 years. Savings over 3 years: $6,480-$16,200. That's a used car. That's seed money. That's 6 months of rent. All from one 25-minute video. All from 15 minutes of configuration. Highest ROI 25 minutes you'll spend this year. ↓ The limitations. I won't lie to you. Open source is not Opus. Not as smart on complex reasoning. Not as good at long-context tasks. Makes more mistakes on nuanced problems. But they are: Free. Capable. Getting better monthly. Good enough for 80% of daily work. Smart cost management isn't being cheap. It's being strategic. Expensive tool when it matters. Free tool when it doesn't. ↓ The one-person billion-dollar company is coming. $401M in year one proved it's possible. The building blocks: AI that codes: Claude Code. Way to run it free: this video. Distribution: the internet. Customers: everyone. Only missing ingredient? Someone who builds. Not reads about building. Not saves posts about building. Not bookmarks videos about building. Builds. Tools are free. Knowledge is free. Opportunity is screaming. You're still "thinking about it." ↓ Your action plan: Tonight: Watch the video. Tomorrow morning: Set up Ollama or Open Router. Tomorrow afternoon: Build something. Anything. This week: Build a second thing. Faster. This month: Charge someone for it. One video. One setup. One weekend. $0 cost. Unlimited potential. Or keep paying $200/month for something you could get free. Keep consuming instead of building. Keep planning instead of shipping. Matthew Gallagher didn't plan a $401M company. He built it. Full video attached. Every method. Every config. Every tradeoff. 25 minutes. Your move. Follow Himanshu Kumar for more breakdowns that turn free tools into real businesses.

Open-source robot arm meets hand tracking [📍GitHub below] It is designed with an industrial mindset but built as a 3D-printed desktop system. PAROL6 paired with a LEAP Motion controller is a nice example of how accessible robot teleoperation has become. • Hand motion is streamed to the robot at 100 Hz via UDP • A pneumatic gripper is controlled by simple fist open and close gestures • The entire robot stack is open source, from mechanics to control software Combine that with low-latency hand tracking and you get a very practical platform for learning manipulation, teleoperation, and human-robot interfaces. This kind of setup is great for experimentation, teleop, data collection, and teaching robots by demonstration All without proprietary hardware or locked software.
