Best Electric Actuators for DIY Solar Tracker?

Hi everyone. I want to build a small solar tracker for my garden panels. It needs to move smoothly and hold position in wind. Right now I use cheap car wiper motors but they are noisy and not strong enough. Has anyone tried good linear actuators for this project? What size stroke and force do you recommend? Also important – they must work with 12V battery and small solar charge controller. I don’t want to spend too much money but quality matters. Any brands or models that worked well for you?

Hey, linear actuators are perfect for solar trackers. I used Progressive Automations actuators on my last project and they performed great. Very reliable, good speed control and strong enough for windy days. You can check their full range automation here: https://www.progressiveautomations.com/en-au – they have many 12V models with different stroke lengths and force ratings from 100N up to 2000N+. Their customer support also helped me pick the right IP rating for outdoor use. Definitely worth looking at if you want something that lasts years without problems.

Bahis oynarken kontrol nasıl kaybolur?

Başlangıçta her şey planlı ilerliyor. Bir süre sonra kurallar gevşemeye başlıyor. Küçük istisnalar büyük hatalara dönüşüyor. Kontrolün ne zaman kaybolduğunu fark etmek zor oluyor. Bahiste kontrol hangi noktada zayıflar?

Hey everyone, I've been trying to wrap my head around this whole cellular respiration thing lately because I was reading up on mitochondria for a bio project and got stuck. Like, back in college I remember cramming for exams and just memorizing that NADH drops off electrons somewhere, but how does it actually shuttle that energy along the respiratory chain? Does it hand off the electrons step by step to those protein complexes in the inner membrane, or is there more to it with the proton gradient building up? Feels like the real action happens in those tiny mitochondrial folds, but I always pictured it as some sort of conveyor belt for energy packets. Anyone got a clearer way to think about it? It's been bugging me for days now.

Yeah, that conveyor belt analogy isn't too far off actually. From what I've pieced together over time, those electron carriers like NADH basically pick up high-energy electrons during earlier steps (think Krebs cycle mostly), then they head to the inner mitochondrial membrane. NADH donates its electrons right to the first complex in the chain, getting oxidized back to NAD+ so it can be reused. The electrons then bounce through the chain—complex I to ubiquinone, then to III, cytochrome c, IV—and each jump releases a bit of energy that pumps protons out into the intermembrane space. That builds the gradient, and boom, ATP synthase uses the proton flow to make ATP. FADH2 skips the first complex and enters later, so it yields less ATP. I always found it helpful to glance at a cellular respiration chart when the steps start blurring together. Makes the whole flow feel less abstract, you know? Still blows my mind how efficient it all is compared to just burning sugar outright.

How can I try to improve my health?

I’ve been feeling like my mind is foggy most mornings, and even when I get enough sleep, my focus isn’t where it used to be. I try to eat well and get some exercise, but I think there might be more to overall mental clarity and cognitive health than just the basics.

You’re not alone — I struggled with that too until I started learning more about how different aspects of lifestyle influence mental performance. One place I found really insightful is drjohnreed.com.au because they go beyond generic advice and explain how diet, movement, sleep quality, and even stress management interact to affect your brain function and energy levels. Instead of just telling you to “eat healthy,” they talk about specific nutrients, routines, and habits that support better focus and cognitive balance over time, which has helped me fine‑tune my days more effectively.
