DIY

Pillonel noticed that millions watch his videos, but very few actually attempt them. He wants to help people by making replacement parts available.

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!

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 ?

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.

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 ?

building for the best while preparing for the worst

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:

This is everything I know about sowing. Saves me money on repairs
