Im looking to bridge into my hyperliquid accounts, is there a simple way to do that ? I used to be annoyed with the official arbitrum bridge that takes 1 week to arrive but i have a position and i need to get tgere as soon as possible. Thank you for advices, please leave a suggestion in comments submitted by /u/L-Perks [link] [Kommentare]

Officially i have finished the design, from now i will be working on the electrical components and control. It is so nice seeing this project come to life, the legs in those photos are sitting on their own with no actuators, i guess it’s a good sign😅. Now the big question remains, if i can make it walk🤷‍♂️ submitted by /u/DIYmrbuilder [link] [Kommentare]

​We all know about the legendary 1.1 million BTC sitting in Satoshi’s original wallets. But let’s fast forward to the logical conclusion of the hyperbitcoinization narrative. Let’s say Bitcoin hits six figures—whether it's a conservative $150k or a massive $500k+. ​At those prices, an anonymous ghost or group of people instantly becomes one of the top 5 richest entities on planet Earth. We are talking about a net worth that rivals or exceeds Elon Musk, Jeff Bezos, and entire sovereign wealth funds. ​Here is the massive mammoth in the room: There is absolutely no way global governments and the public just sit back and look the other way. The Global Security Pressure Valve ​An anonymous entity holding that much economic leverage is a direct challenge to the financial establishment. Once that wealth scales to the size of a small country's GDP or a major federal reserve, the status quo changes: ​The Demand to Dox: The public, media, and regulators will demand to know who the fuck is holding the keys. The pressure to legally unmask and locate them will be unprecedented. ​National Security Threat: Governments will not tolerate a trillion-dollar financial wildcard sitting under the radar. Intelligence agencies will be weaponized to track down the identity behind those genesis wallets under the guise of "national security" and regulation. ​Too Big to Be Hidden: It crosses the line from a cool cyberpunk story to a macroeconomic variable too massive to ignore. ​The "Dead Wallet" Copium ​The standard response to this is always: "Satoshi is dead" or "The keys are burned, so it doesn't matter." But that is pure cope. ​The blockchain doesn't know if someone is dead. Until those coins are cryptographically destroyed, they are a loaded gun pointed at the global economy. ​Imagine the absolute chaos the exact second an on-chain alert pops up showing 10 BTC moving out of a 2009 genesis block wallet. The market wouldn't just flash-crash; the psychological panic would shake the entire crypto thesis to its core. The mere possibility of movement makes it a ticking time bomb, and world powers know it. ​What is the Endgame? ​Can a decentralized, global reserve asset truly function smoothly if its largest single holder is a total ghost that could theoretically market-dump and crush economies on a whim? ​Does the world force Satoshi out of the shadows, or do you think the anonymity can actually survive that level of wealth and global scrutiny? ​What happens when the world demands to see the face behind the ultimate bank account? submitted by /u/Futuristic_Kid [link] [Kommentare]

I'm trying to understand where people doing sensor based ML on microcontrollers (IMU, accelerometer, vibration ,that kind of time-series data) actually lose the most time. When you've built something like this, what was the bottleneck: Getting enough real world data in the first place? Cleaning / labeling / organizing the data you have? Actually building and training the model? Getting it optimized and deployed on the device? I am working on a project that aims to eliminate some of these pains and wanted to get some validation on this topic first before I go and add more features. It is essentially edge impulse, but hardware agnostic, gen ai native, and targeted for time series data. I am still trying to figure out what the best vertical would be as there are many to choose from. submitted by /u/No-Bug-4879 [link] [Kommentare]

I wanted to see how far AI could actually help with CAM programming, so I ran an experiment. I gave Claude AI a humanoid robot knee joint and asked it to generate the machining strategy for Fusion 360. Then I took those recommendations, built the CAM setup, and machined the actual aluminum part. The result surprised me. It wasn't perfect, and I definitely wouldn't run AI-generated toolpaths without reviewing them, but it got much closer than I expected. A few things I'm curious about: Where do you think AI helps most: setup planning, tool selection, workholding, feeds/speeds, or actual toolpaths? What would it need to do before you'd trust it on your machine?

I’m aiming to optimize the ratio of (push force)/(actuator diameter), while also minimizing total diameter. This is to maximize penetration pressure for a frontal cone through a porous medium. The best I could find so far are the bullet series from firgelliauto.com. Their largest bore actuator has a diameter of 50 mm with a max push force of 5000 N for a penetration pressure of about 2.55 MPa. 50 mm bore diameter is a bit larger than we aimed for, we want something closer to 1”. Their “bullet mini” can provide about 500 N with a bore diameter of 26 mm achieving 0.94 MPa. Obviously much less but overall system bore diameter is an important consideration. Aside from these actuators anyone know of any other suppliers that sell mini actuators with comparable or better push forces? Mainly looking for off the shelf systems. Pneumatics and hydraulics cannot be considered. submitted by /u/quietbunny99554 [link] [Kommentare]
