Hello all. I got a JIMU dragon robot kit for my birthday. The problem is that the build guide is only found in the app which is apparently not available for Android phones anymore... I don't know how they're allowed to be selling the kits and advertising the app for Android, but here we are. I think I can manage to code the bot outside of the app, but I have no idea how to put it together. Is there any chance somebody has the step-by-step on putting it together? Or has a way to get it without installing potentially unsafe versions of the app? submitted by /u/Popular_Razzmatazz70 [link] [Kommentare]

It finally picks up the object. It took me the whole afternoon to get this working. At first, I was aligning the object with the end-effector frame instead of the gripper frame, so I had to change that. I also had to split the motion into stages. From the initial view, the object center was not estimated accurately enough, so the robot first moves to a higher hover pose, gets a better view from above, recomputes the target, and then performs the grasp. The final grasp pose still looks a bit strange to me, and I needed to tinker with some extra parameters because in this pose the object is out of the camera field, so I ended up with a grasping pose via trial and error. This is my first time building something like this, so I am not completely sure what to think of it. I tested it several times, and it picks the object reliably. So I guess: if it works, it works. What do you think? submitted by /u/nettrotten [link] [Kommentare]

Convince me why this wont happen. Claude says: If BTC keeps dropping, MSTR stock drops harder. When MSTR is down, Saylor can’t sell new shares or preferred stock at good prices to raise cash. But the ~$1.2B/year in preferred dividends still has to be paid regardless. So he’s forced to sell BTC to cover them. Selling 4%+ of total BTC supply into a weak market pushes BTC down further, which tanks MSTR more, which makes the next round of fundraising even worse. Each loop tightens the next one. He already broke the “never sell” rule on June 1 with 32 BTC. The convertible bond puts hitting in late 2027 and early 2028 could demand $3-4B in cash on top of the dividends, accelerating the whole thing. submitted by /u/fatchinaman69 [link] [Kommentare]

Hey all I built FulgurPool, a new BrowserCoin mining pool, together with FulgurMiner, a free headless/terminal miner for it. Both are live now at fulgurpool.xyz. You can mine however you prefer: one-click mining directly in the browser or FulgurMiner if you want something better suited for longer sessions / your own machine outside the browser Pool terms: 2% pool fee PPLNS, so you earn from your first share 0.25 BRC minimum payout Pool covers the network fee, so you keep the full payout amount 3% finder’s bonus if you mine the block yourself Custodial, but transparent: live stats, found blocks, and payouts are visible on the dashboard ⚡ Hard-fork ready — supports the BrowserCoin scripting hard-fork on Jul 5, 16:00 UTC and switches automatically. I’m also running a small launch bounty to get the pool started: The first 25 addresses to mine 24h cumulative each get 10 BRC. Browser mining and FulgurMiner both count. That’s 250 BRC total, paid automatically. You can try it here: fulgurpool.xyz Why FulgurMiner? Headless — runs in your terminal, so there’s no browser window you need to keep open or in the foreground. Works fine in the background or on a server. Faster — native Rust core across all CPU cores. In practice it’s around ~2× faster per hash than the browser’s WASM implementation. Self-tuning — Smart mode auto-tunes itself. The Considerate profile only mines with spare CPU and backs off when you actually need your machine. Hard-fork ready Free and open-source — you can check the code here: Github Repo. You only need your wallet address; it never asks for a password or private key. Questions, bug reports, feedback, or “this part is confusing” comments are very welcome. It’s still early, so real testing from people here would be genuinely helpful. submitted by /u/alpenmilch411 [link] [Kommentare]

Just opened a pack of these cards and found the flaming pile of dung Kevin rose shiny. It's like a mildly interesting crypto of yesteryear tidbit. Back when times were high for pfp collectors and the grifters too. submitted by /u/NonConforminConsumer [link] [Kommentare]

I think the majority of us still classify cryptocurrency cycles as bullish and bearish over the past 4 years, when in fact, the cycles are more comparative to bearish and more bearish in my opinion. I personally think the whole cryptocurrency thing is over, but I think Bitcoin still has a few 500% plus pumps left in it before it finally stays flat or goes down slowly for the next 20 years or so. My next bet is not if, but when MicroStrategy now Strategy collapses once Bitcoin goes down to a certain threshold, and they can no longer pay the bills they promised to investors. Think FTX, but a 2026 or 2027 version of it. Once this transpires, expect Bitcoin to go down to around $15,000 to possibly even $10,000 per coin. When it does happen, I think buying here and riding it back up to $100,000 over the next 3 to 4 years and then selling would be the optimal move in my unprofessional opinion. What do you think will happen? submitted by /u/Ryanopoly [link] [Kommentare]

Hey everyone, Over the past year I've been building this as a personal project (no company behind it, just me): a Python-based platform that takes measured input/output data from a physical system, automatically identifies the best mathematical model for it, designs an optimal controller (PID, LQR, MPC, and others), and generates ready-to-deploy C and Python code for the hardware. I've verified it extensively on synthetic benchmarks — DC motors, thermal systems, oscillatory mechanical systems, nonlinear processes — and it's holding up well. But I need to stress-test it on **real industrial or embedded data** before I can call it production-ready. **What I'm offering:** - Full analysis of your system's data (no charge) - A complete technical report: model accuracy, controller performance, stability margins - Ready-to-compile C code + Python implementation for your hardware - Everything is yours to keep and use **What I'm asking in return:** - A brief description of who you are, what company/project this is for, and what you're trying to achieve - Your honest feedback on the report and the generated code — does it make sense? Is the output useful? What's missing? This is genuinely valuable to me as a solo developer - Permission to mention you as a reference on my CV - Permission to cite the project as a validated use case (no sensitive data published — just "successfully deployed on [type of system] at [company/domain]") I'm keeping this to 1–2 pilots so I can give each one proper attention. **What kinds of systems are a good fit:** Motors, actuators, thermal processes, fluid systems, robotics, HVAC, industrial automation, biomedical devices — basically anything where you have logged sensor/actuator data and want better control. If this sounds useful, **send me a DM** with a short description of your system and what you're trying to achieve. I'll let you know if it's a good fit.

What do you think of this cryptocurrency? When I read various discussions, BCH rarely comes up. I guess BCH isn't a very “trendy” crypto these days, even though it seems solid from a technical standpoint, and its adoption is also strong. submitted by /u/dannyxdii [link] [Kommentare]

Crypto lost all its appeal when AI appeared on scene. All the money got siphoned out there. It looked like profits there were bigger. It _could_ so happen that as we see AI struggling (crumbling? Collapsing?), that crypto could become interesting again. submitted by /u/tawhuac [link] [Kommentare]

I'm just making this post to see if anyone else using a Ledger hardware wallet is unable to connect and sign transactions on desktop with Rabby on Google Chrome. On the 18th, I contacted Rabby's support through their Discord/GitHub, but I haven't received any proper update other than, "Have you tried contacting Google Chrome support?", which I thought was a pointless question with no follow up questions and It still doesn't work, so I just wanted to see if I'm on my own with this issue. I like Rabby Wallet, but their support staff are completely useless at relaying serious issues to whoever can actually sort them out. My Ledger works fine and allows me to connect and sign using Rabby on other browsers and whilst using other wallets, but it only takes issue with Rabby on Chrome. submitted by /u/Sam_Loopring_eth [link] [Kommentare]

Hi all, I’m working on a research project exploring how stateless LLM-based chatbots handle long conversations and whether important earlier information is still reliably retained over time. My idea is to: Run a chatbot using an LLM API without any external memory system Introduce key facts early in a long conversation Continue with many unrelated messages (hundreds of turns) Later test whether the model can still correctly recall those facts at different intervals I’m planning to measure recall accuracy and how it changes as the conversation grows. Before I go deeper, I’d really appreciate feedback on: Is this a valid way to evaluate long-context memory limits? Are there better benchmarks or methods already used for this? What metrics would make this more rigorous and convincing? Any suggestions or criticism are welcome. I’m trying to make the evaluation as solid as possible before building it out. Thanks! submitted by /u/QuietAccountant4237 [link] [Kommentare]

Reports suggest that a major institutional investor sold a significant amount of Bitcoin this week. If confirmed, do you think events like this have a lasting impact on Bitcoin, or are they simply part of normal market dynamics? Curious to hear the community's perspective. submitted by /u/Mission-Stomach-3751 [link] [Kommentare]
