BattleMeshV15 [2023] - Wireless Battle of the Mesh @ Calafou (Barcelona, Spain) / 8th to 14th of May
The Battlemesh v15 will be hosted by the fabulous Calafou / colonia ecoindustrial postcapitalista members in Barcelona, Europe The community voted for this year's edition to take place from Monday 2023-05-08 to Sunday 2023-05-14. The Calafou compound is very spacious and offers plenty of room for hacking, workshops, socializing, building test beds and more!

This has been posted already, my bad, it's here : ![]( #### Here is a short summary I (OP) made : ​ - This one is a static **exercise bicycle** with no gears. ​ - You also have to **build a board to convert current / voltage** on the output if you want to charge batteries or power electronic devices that are sensitive to power changes ​ - Power output overview : "The power output (W) of a bike generator corresponds to the voltage (V) multiplied by the current (A). **We obtained roughly 100 watts (12V, 8-9A) of power during a short and heavy workout.** During a moderate effort – which we can sustain for a longer time – power production is between 45 and 75 watts. The power output not only depends on the bike but also on the person who operates it. Athletes could produce more power, while couch potatoes would (initially!) generate less." ​ - The simple dynamo is under the wheel. So, much friction. A better system could waste less energy ?

Make a high powered solar panel from broken solar cells
Reminder : - Parallel wiring **increases amperage and voltage stays the same**. Each cell in a parallel circuit is wired positive to positive and negative to negative. ​ - Series wiring (mostly what you will use for solar cells} **increases voltage and amperage stay the same**. Each cell in a series circuit is wired positive to negative, the remaining positive and negative are you leads. You'll notice batteries in flashlights installed in series.

Updates on Mesh networking firmwares and compatible Hardware / chipsets
Since OpenWRT introduced Mesh networking I haven't been able to use or test anything, and I'm looking for good ressources to help choose between protocols, firmwares, and hardware / device chipsets ? I know about OLSR, B.A.T.M.A.N, and had a chance to run and test [Byzantium]( Live OS back when it was a thing. - Is B.A.T.M.A.N the better approach for an easy/reliable Mesh setup ? Does it run easily on simple devices (not routers) ? - For routers, are there other open source firmwares more suited to Mesh networking than openWRT, that will work on a lot of devices and are reliable ?

Wall Hitch Mount for Bike Storage
Someone at work was throwing away an old hitch mount bike rack a while back. I hated to see it go to waste, so I built a "hitch" for the wall of my garage: ![a hitch mount bike rack mounted to the wall]( ![the same bike rack with two bikes on it]( This is a little project I worked on over the weekend once I realized that my Wii mini, which I previously didn't think could be very useful for me, could be set up with the homebrew channel using the bluebomb exploit. I own a nes mini, snes mini, and playstation mini, and they're all neat toys, but the problem with all of them is that I can't really use them in my living room. The TV is mounted on the wall fairly high up, and I don't have a shelf or anything, and I don't feel like running 100 feet of USB cables all over the place just because I might want to play some super nintendo games once a year. The Wii was a nice solution by itself. It's small, and you can plug a classic controller into the wiimote so you can play games wirelessly and tuck them into a basket for the 364 days you're not playing wii games. The Wii mini is different from the Wii in that it's a much simpler device. It doesn't have an SD card slot, it doesn't have a wifi transciever, it can't use Ethernet at all in its unmodified form. Also, the device doesn't have a frontloading DVD drive like the wii, instead it has a top loading DVD drive like the original playstation, so you can't just simply bolt it to the wall with a piece of wood or strap or plastic like you could with a Wii, because you won't be able to open the DVD drive. Being able to run homebrew was the final straw that made the project viable and interesting. My solution ended up being very simple: The sides of the wii mini are at an angle and come to a point. I measured the dimensions of that angle and created a wall mounted bracket, then printed 3 of them in PLA. A standard Wii has many mounting brackets available since the Wii was the most popular game console of that generation, but the wii mini was a last gasp and so it isn't really popular and there aren't really options out there, so this is a perfect solution for home manufacturing. I realized that the tolerances required to hold the wii mini using these was extremely tight, so I used a piece of lined paper to create a template by putting the Wii into its mounts sitting on the table, then I used a felt marker to mark drill holes. Even so, it wasn't as precise as I'd hoped, and I also had an issue with the anchors I used. I've used plastic screw in anchors on a few other projects and it wasn't a problem, but these anchors absolutely hated my living room wall, so that became way more complicated than I would have liked. It does work, but it's not perfect. If I were to design something like this again, I would remove the requirement to perfectly mount the anchors by printing a piece of plastic holding the three pieces in the exact spot so I didn't need to mount them perfectly. I would probably try to make it a hangable holder so I could just put a couple hangers on the wall and hang the wii holder off of it rather than try to drill securely into the wall. Regardless, it does work as you can see, and I'm happy enough with the results. My favorite prints are the ones that quietly become a permanent part of my life, and this is a great example of that. The Wii is being held behind my TV, hidden but accessible.

This guy does a lot of neat stuff. I watched a few electric bike videos he did where he tried building e-bikes with various features.

Suggestions for ways to repair kevlar gloves?
Work gloves. They're kinda expensive.
