A meme about a meme about memes. Impressive.

Finally, bull milk!

Can't complain about that one!

Well that is one thing I'll never have. My appendix got removed years ago.

Do you mean the steam deck?

I just use tweezers and a blue flame lighter. Heat it for 5 seconds then put it in the plastic. Then use the back of the tweezers as a flat surface to push it all the way in and level it.

This worked well so far and I really don't see the need for a special soldering iron bit or a press like this.

I played it too.

I got an Orbiter 1.5 extruder and have been quite happy about it since. These days you'd be better off getting an Orbiter 2. As for the toolhead, there should be Ender 5 compatible mounts available on Printables or Thingiverse, if not you could design your own.

Creality also has its own direct drive, the Sprite Pro. That may be worth looking in to as well.

You can import a STEP model of both the Ender 5 and whatever mod you want to make to it and model your toolhead around it, that is what I did with the Mercury One project.

It's worth the effort imo.

 

In a transformer, why are both coils apart from each other? Wouldn't make more sense to have the ferrite core (tube shape), wind the primary coil around that and then wind the secondary coil on top of the primary? So that the magnetic fields are as close to each other as possible?

 

Hi all

A higher nozzle diameter has the benefit of being able to print faster due to to bigger layer width. There is a tradeoff, you'll have to lower print speed and/or raise temperature to maintain proper layer adhesion. That means that there is an optimal nozzle size for a given print speed/temperature combination. You also don't want temperature too high because it will burn/degrade your filament.

In my experience layer adhesion is quite poor with a nozzle of 0.8mm and it also prevents you from printing finer details (gear teeth for example). The tradeoff versus a 0.4mm nozzle doesn't seem worth it especially if you print overnight.

What are your experiences?

 

Hi

I'm interested in building my own solar panels mostly for educational purposes. The idea is to use individual solar cells and solder 36 of them in series to get about 18V open circuit voltage. It's what commercial solar panels have as well so its easier to integrate later.

The cells are bonded to the substrate using optically clear silicone or EVA. Not sure which is better. Polyurethane is not good because the mere mention of humidity will cause tons of bubbles.

As for the substrate. Optically clear tempered glass is prohibitively expensive unless bought in bulk. Normal glass is significantly cheaper but could that be a safety hazard? I seriously doubt that thermal shocks are strong enough to break glass sheets unless cold rain falls on it.

Has anyone tried plexiglass/acrylic? It's UV resistant but could bend/warp at higher temperatures breaking the cells.

Perhaps using screen protectors for obsolete phones/tablets could work as well. It's really thin and strong but I don't know it holds up in a hailstorm.

Would love to hear from your experiences in DIY solar panels.

 

I'm interested in learning how to make a proper PCB rather than perf board with wires all over the place.
