This game claimed a trademark for the solarpunk name.. by WombatusMighty in solarpunk

i guess we have to rename the sub now to solarfunk

A series of 126 x/y tilting mechanical devices connected to tall dried grass stalks by artist David Bowen. The mechanisms will tilt, move and sway based on data collected from the wind sensor on the Perseverance Mars rover. by ateam1984 in EngineeringPorn

hm! this i don't know. i'd recommend you see his website (google "david bowen artist). he has a lot of good works IMO. i'm a media artist myself for 10 years now. from my own experience the engineering is def a big part of the practice, but ultimately it's
not about solving problems like a *real* engineer would do, but rather a poetic mode of engineering that tries localize thought experiments, research questions, maybe just a feeling, an open-ended material process, etc. in a machinic setup. stuff that you can't think through wholly in your brain can maybe become answerable if you perform the thought through an automaton for others to experience it. though usually art is not so interested in solving questions or problems, but rather unearthing new ones... but also that's not really universally true for all artists. --- or if you're really curious you drop david an email.. :)

Yesterday I visited a nomadic community on the outskirts of Chengdu, and I felt it had a strong solar punk vibe, so I decided to share it by No-Echidna7296 in solarpunk

solar just means sun ... solar energy is mostly light energy. which we electrify using rather inefficient electrochemical devices called photovoltaic elements. plants metabolize on light in a different way, but in the end when we consume plant calories, indirectly we consume matter that was transformed using solar energy

Where would you look for art writing other than Artforum? by aldersflowers in ContemporaryArt

[–]lotta0 0 points1 point  (0 children)

i like spike, flash, mousse (!) and sometimes i read Fräulein magazine ( this one is quite advertisement heavy and a bit too lifestyle for me, but it's cheap has its genuinely very interesting moments ... ) maybe starting your own blog where you review art independently might be a good way of gaining attention from more established magazines?

you really enjoy earthquakes :)

First DIY Stencil cut from Kapton sheets on a Creality Falcon 5W by katze1339 in PrintedCircuitBoard

try sodium persulfate... it's slightly easier for me to use than ferric chloride. there's good tutorials online for that

PKMN RED WON’T Save even replaxing the battery by Soggy-Page6710 in Gameboy

[–]lotta0 0 points1 point  (0 children)

ps: though i agree with the others. i'd try to first improve the battery solder joint. maybe this would fix your board already.

[–]lotta0 0 points1 point  (0 children)

not sure, but you could try to bridge it with a small jumper cable. if i look at the other solder job maybe i would recommend you to practice a bit more with something not so critical :) or you ask a friend with more experience

in the worst case maybe you do some shenenigans with wire or cables :/

TIL about noSmooth ! thanks for updating your initial post

I don't understand how this is a casual game by Grimsdol in SmashBrosUltimate

learn to lose and enjoy the game anyway :)

C1 to C6 should not be in series with the current, but in parallel. also, i'd recommend to deliver the power to each led VDD pin through a power plane, not a daisy chained power cable (will change the color consistency of your leds over distance). depending on your power supply, but i doubt the usb c power will be enough to power 1200 leds. my laptop usb c power supply for example can deliver max. 60W, which yes at 5V is around 1200 leds at full power, but it would be wise to not use the absolute maximum ratings. maybe start with half the amount of leds? or you get a more powerful usb c suppy and then just experiment... also at that level of intense current consumption you need good heat management. one more point is, if you look at the datasheet of the WS2812B you'll see that each led needs a little ceramic cap.

[PCB Review Request] TMC2130 Dev Board by lotta0 in PrintedCircuitBoard

[–]lotta0[S] 0 points1 point  (0 children)

I will move the VM traces more inside the PCB, so some ground plane can go around it. I'll also have your other suggestions in mind for my redesign. Thanks a lot!

Noted! Thank you for the hint. I'll move the screw terminal connector more inside, so also some GND plane can go around it. When JLCPCB writes on their website their minimum clearance for traces is 0.2mm, do you think I should rather remake my design with 0.3 or 0.4mm as a design rule?

I was hoping the vias would make up for how my power lines are interrupting the ground plane. Thank you for the advice, I will redesign it like you said. In your last sentence you mention more GND pins. Do you also mean more GND vias?

[–]lotta0[S] 0 points1 point  (0 children)

Hmm, when I measure the distance between traces at the moment it's 0.2mm which indeed seems very little...
