- Comment on Battery charge in parallel discharge in series 2 weeks ago:
The idea of the battery pack is to provide energy for a household. The reason I’m considering such a large amount in series is that it would make an inverter much more efficient and easy to make. An EGS002 based circuit for example relies on a 400V DC, which I find very difficult to make out of lower voltages. Especially when high wattages are involved. There are no DC-DC converters commercially available with around 55V input (16s li-ion) and 400V output at 4KW. There are however commercial inverters available such as the Victron Multiplus II 48V that can deliver about 4000W of AC. This would suit my needs however I want to DIY as much as possible. I also have plans for a self made solar charge controller and possibly even a wind controller as extra modules next to the battery charging circuit and inverter.
Solving the issue of converting high power 55V to 400V DC would remove the need for a high-series battery pack as well.
Indeed blindly dumping the charge into a battery is not the intention. There will be additional circuitry to prevent cells from overheating and to limit the inrush current that they receive but the general idea is a capacitor that floats between 4.2V and Vcell.

- Comment on Has anyone sold or otherwise handed off their 3d printing business? 3 weeks ago:
Have you considered lasercutting or CNC milling as well? And what about lithophanes?
3D printers are highly accessible to people, even people with no technical knowledge can just buy one, download models and have it print successfully. Selling 3D printed parts pretty much only works if you do design as well and not many people request something like that. I don’t think you can make a feasible business out of 3D printing alone.
And there is mechanical design and aesthetic design, which both are completely different practices. I mean things like making a TV mount or a tube holder vs making a detailed Warhammer 40K model. You need different software and skills for both of them and it consumes a lot of time to do well.
CNC milling and lasercutting is not as wide spread as 3D printing is so you could still end up finding people interested in objects made this way.
- Comment on 18650 battery pack 16s2p design 4 weeks ago:
Because I have a metric shitload of them available. Indeed if i was going to order fresh cells 21700 is better especially for a home battery system.
- Comment on 18650 battery pack 16s2p design 4 weeks ago:
The plan is to have it function as a home battery, connected to either a solar panel or a small balcony wind turbine. I also want to charge it when the electricity cost is low and discharge when the electricity cost is high on average.
Another part of the project is to build a grid-tied inverter.

Ooh, a deshittified version of imgur? Or did you invent time travel?
- Comment on 18650 battery pack 16s2p design 4 weeks ago:
Thanks! There’s about 3mm space in between the batteries so air would easily flow through. I’m not sure if that is preferable though, ideally the cells do not get warm at all.

Okay so if I want to print a gun I’ll just tighten an eccentric nut or belt tensioner. Lol
- Comment on FYI (opinion.) don't buy an MMU 4 weeks ago:
I think a dual nozzle system is already good enough for most users. Especially when your print area is large enough to make it feasible.

- Comment on Shh 1 month ago:
Yeah. True. I’m a programmer of those things and I make an effort to be as efficient as possible with tips, ie mixing with the same tip and compensating accuracy for it. It’s more difficult but worth the effort imo.
- Comment on Shh 1 month ago:
I know. They’re definitely not environment friendly. Still much better than manual pipetting.
- Comment on Shh 1 month ago:
That’s why you use pipetting robots. Just sit back and watch the show.

- Comment on top-layer delamination solved by lower speed 2 months ago:
Lower speed means less flow through the nozzle and warmer plastic. It will have more time at the melting temperature and therefore stick better to the previous layer.

The devils lettuce is also lettuce, right?
- Comment on Indoor lettuce growing in 3D printed pots 2 months ago:
I’ve used milk jugs as plant pots before. It’s food safe material and you can easily design a build around it. Better not have anything 3D printed come into contact with food.

- Comment on Ender 5 Mercury One.1 10mmrod mod 2 months ago:
The fan ducts are in the Printables link. They are designed for the rod system so if you can find 10mm rods long enough for an Ender 5 Plus it should work.

- Comment on Microsoft Is Now Being Sued Over Sunsetting Windows 10 2 months ago:
It’s much easier to install Linux these days than it is to install Windows. And with KDE Plasma the user experience is really similar. As for the distribution I would suggest OpenSuse as that has very little requirement for terminal commands, they’ve packaged GUI elements in the whole distro.
As for Tumbleweed vs regular, that’s up to you. I’m happy with Tumbleweed.
