Got my robot vacuum running Valetudo the other night...


....then proceeded to get stoned and watch it roam the house, doing it's thing.

And then it dawned on me - I now have a completely self-contained autonomous robot that is free to roam my house, not attached to any cloud services, doing actually productive things; and I have full control over it.

I know it's an odd thing for a grown-ass man to get excited over, but I can attest to the fact that 14 year-old me would be over the fucking moon about this. My parents got me the first Lego Mindstorms set for Christmas when I was younger, and I had an old Palm V handheld from my uncle; I managed to figure out how to control the Mindstorms controller with the Palm V's built-in IR blaster, using just a "universal remote" app.

How far we've come.... Just accomplishing this has given me a renowned motivation for self-hosting shit; it's incredibly freeing. And knowing that the manufacturer of this vacuum could access it at any point and just outright shut it off without my knowledge.... I don't have to deal with that anymore.

The robot is a Wyze "Robot Vacuum" (model WVCR200S), which is based on the 3irobotix CRL-200S - the very same robot one author recently discovered was being intentionally shut off after he had blocked some telemetry URLs. I bought it for $20 on eBay. Fully functional, but the battery only lasted ~10 minutes from a full charge. Luckily it just uses four 18650 cells in series, so replacing those was a pretty simple task. I did not buy a whole new pack (most of them are expensive and falsify their true capacities), rather opting for individual Molicel P30B 3000mAh cells for ~$5 each. I ended up having to peel off the nickel tabs from the old cells and carefully solder them to the new cells, as I don't have a spot welder. Lots of flux and a soldering iron set to 450C were key here. I would not recommend that method ๐Ÿ˜….

Edit: My parents dropped by last night and I gushed about it to them... My dad is a tech guy, so he was pretty interested. My mom was more "I have no idea what you're talking about but I'm happy that you're happy" ๐Ÿ˜‚๐Ÿ˜‚

I've patiently waited until the flashing guide for the roborock s8 was out, went to buy the s8 pro ultra, just to discover valetudo has dropped the support, because appearently a different version of the same robot was silently released, that would've been turned into a brick if I tried the installation procedure.

Now I have a dumb robot. It does like 95% of what I expect it to do, but I might at least solder an ep32 to the top buttons so that scheduling through the home assistant would be possible

in reply to deafboy Selfhosted reshared this.

Yeah, that's a rough one. Manufacturers really don't want us mucking about and will release different versions under the same name all to obfuscate that process.

A lot of TVs are like this as well; we have a curved Samsung 55" that lost it's backlight last year - not only did I need the model and serial numbers, I also needed the specific T-con board revision. A similar thing happened on my former TCL Roku TV several years before. Same deal.

I have one of the older model rumba's. It does have wifi capabilities, but I've never connected it. Do the newer models require you to connect to wifi? Valetudo looks interesting tho.

in reply to irmadlad Selfhosted reshared this.

I'm honestly not entirely sure. I've been eyeballing Valetudo for a few years now, but the price of the supported robots was out of my budget until I happened onto the $20 Wyze from eBay. Took a chance and won big. I'm into it a whopping $65. And a bit of labor to swap the motherboard (mine refused to run ADB at all). But that's the fun part for me.
in reply to irmadlad Selfhosted reshared this.

Responded with the wrong account... I try not to have any crossover between my accounts, but here we are...

Anyway.

Do the newer models require you to connect to wifi?


Probably. I only have the two robots: the aforementioned Wyze, and a cheap Eufy Robovac 25C

Valetudo looks interesting tho.


It's really quite fascinating. Valetudo is not a 3rd party firmware - it's a cloud replacement that's hosted on the robot itself, and also runs a webserver which gives you access to the actual controls and relevant firmware options.

Yeah but can it run Doom? That's the burning question

in reply to irmadlad Selfhosted reshared this.

Well these robots run a Linux distribution as a base. So yes, sure, they will run doom just fine.

If you can manage to get video out, I'm sure it can be done. Maybe you can even stream Doom to a web browser.

A Growing Number of โ€˜Repair Cafesโ€™ Are Popping Up Around the World to Curb Consumer Waste - Inside Climate News


in reply to PhilipTheBucket Uplifting News reshared this.

Iโ€™ve thought about up-cycling stores, too. Probably not as nice as just getting your item repaired, but if itโ€™s items you no longer want, and no one else will either, could be cool seeing what can be made with it and kept out of the landfill.
in reply to PeacefulForest Uplifting News reshared this.

#newzealand has #ecostores - when you taken things to the tip / #landfill - they are sorted through and anything useful is put into stock at an #ecoshop where people can buy it for nominal amounts. In the #uk its illegal to - which seems crazy. Id love to see my local waste transfer station to have a 'reuse' option - so you could dump your rubbish and selectnthings you need from items other have left.

While many Web Hosters are becoming big tech resellers, Ionos and @nextcloud just released an alternative to GSuite and M365. It's built entirely on open-source software and is even cheaper than most of its competitors. Let's hope others are learning from that example.

Garbage in . Garbage out. If the content is focused in applications AI will just relfect that. Its not a thinking function.

We Surveyed 2,158 Self-Hosters: Here's What Keeps Us Hosting


Hey everyone,

We're excited to finally share the results summary of the survey we posted in this community a few months ago! A massive thank you to the n=2158 active self-hosters from communities like r/selfhosted on Reddit and c/selfhosted on Lemmy.World who participated. Your input has led to a comprehensive academic paper that investigates the core reasons why we stick with self-hosting over the long haul.

Our study examined which factors most influence the Continuance Intention (the desire to keep using) and Actual Usage of self-hosted solutions. We confirmed that self-hosting is a principle-driven and hobby-driven practice, challenging traditional models of technology adoption.

The Top 3 most important Positive Drivers for Continued Self-Hosting

The most significant positive predictors of your intention to continue self-hosting were all rooted in intrinsic satisfaction and personal gain, rather than just basic utility:

  1. Perceived Enjoyment (The 'Fun Factor'): The sheer joy, pleasure, and personal satisfaction of configuring, maintaining, and experimenting with your own systems is a powerful, primary motivator for long-term engagement.
  2. Perceived Autonomy (Control/Digital Sovereignty): The desire for explicit control over your data and services, and the rejection of vendor lock-in inherent in third-party cloud services, is a fundamental driver.
  3. Perceived Usefulness: The belief that your self-hosted solution efficiently delivers specific personal outcomes (e.g., operational efficiency, powerful features, and privacy) is important, but its influence was less pronounced than Enjoyment or Autonomy.

The Critical Role of Technical Skill

We found that your self-assessed technical ability, or Perceived Competence, acts as a crucial link between wanting to self-host and actually doing it. Having a high intention to keep self-hosting is only half the battle. Your confidence in your technical skill is what gives you the self-assurance to handle the necessary, demanding tasks like maintenance, security, and updates. Importantly, a certain critical threshold of knowledge is required before competence starts driving that actual, continuous usage.

Other Key Insights

  • Privacy Matters: Concerns about privacy in cloud services positively influence the decision to stick with self-hosting.
  • The 'Push' Factor: If a user reports high Trust or high Autonomy when using commercial cloud services, they are significantly less motivated to continue self-hosting. This confirms that dissatisfaction with the commercial cloud effectively "pushes" people toward decentralized alternatives.
  • Maintenance Isn't a Dealbreaker: The high effort and time required for upkeep, or Perceived Maintenance Cost, was not a statistically significant factor for giving up on self-hosting. Our intrinsic motivation is powerful enough to absorb the necessary effort.

Implications for the Self-Hosting Ecosystem

For developers and the community, these findings suggest that sustained usage depends not only on functionality but also on fostering empowerment and a great user experience. By making self-hosting more enjoyable and reinforcing the user's sense of digital sovereignty, we strengthen the intrinsic motivation that fuels this movement.

Thank you again for helping us publish this research on the future of decentralized digital solutions! This work would not have been possible without your participation.

Now this is how you detect whether an election was stolen. Humans choose rounder numbers.

in reply to Information Is Beautiful

they suggest that someone rounded up or down at the least.

But this is focusing the issue on the easiest to detect version of vote manipulation.

This is not how you "detect if an election was stolen" because it is not suggestive of any particular outcome. The way you find this out is over whistleblowers and using many sources.

Election manipulation happens all the time, especially in the west. Propaganda and oppression of opposition has been done since more than 100 yrs.

Europe has successfully launched Sentinel-1D, the latest satellite in the Copernicus fleet, aboard an Ariane 6 rocket from French Guiana.

It'll scan land and sea every 12 days with radar sharp enough to detect floods, ice melting, ship movements, oil spills and even the quiet shifting of the ground.

Free data will propel climate science, disaster response and maritime safety.

My Dream of a Home Router / Server


What if you could buy off the shelf a box based on #opensource software and hardware that you could plug into your internet connection. You could connect to via Wifi and it would allow an average person to fairly easily configure, via a guided setup, a self hosted Cloud Drive, Social Media server, home automation service, VPN end point, email server and other commonly useful software?

What if that box allowed that person's friends to authenticate and to that box and link a box they own, either close by or remotely. It could extend connectivity and estabilish a chain of trus, provide a level of encrypted backup of content from that box and make assertions about the users on that box such as - This user account is owned by this person, this user account is over 18?

This is a dream. I know I'm rambling. #openwrt, #yunohost, #seflhost, #chainoftrust, #fediverse !Selfhosted
