Looking for input: i want to build a bike pusher trailer (slrpnk.net)
 

i regularly use various bikes, a single speed, a mountain bike, and a couple of ebikes. i've been thinking of starting a new project converting a normal single-wheel trailer into a motorized self-propelled trailer. I need some input.

primary consideration is that i want it to be self contained, mostly meaning it carries its own battery and electronics, and preferably i do not want any cabling from the trailer to the bike.

i want the trailer's motor to engage when the bike is in motion, and provide torque to offset trailer weight, etc.

the idea i have in mind is using an accelerometer tied to the throttle input of the motor controller to detect when the trailer is in motion and engage the motor. this way i could just start pedalling and then the trailer's motor kicks in, and disengages when the bike's speed drops below a threshold (or when i hit the brakes). i'd also have a switch of some sort to prevent the motor from engaging when the tow bar is not connected.

is this stupid? is there a better way? am i missing something important?

What JRPGs have you played 2025? in c/jrpg@lemmy.zip

100% complete playthroughs of all three of Xenoblade Chronicles 1, 2, and 3.  including the expansion packs.

I'm a single dad and only played in my own time, and started in February; finishing all three felt like a major personal achievement.  Overall roughly 800 hours total (but again, went for 100% completion, only missed a couple of the superbosses), and finished the whole run in Dec 25th.

    I'm about to give up my organic balcony gardening experiment. This is a cry for help. in c/balconygardening@slrpnk.net

    if you live in a place with a definite winter/summer cycle, then if you start with aphid & ant control early on (when it's still cooler) you'll have better luck keeping them away. I do realize it's too late in the season now for that, but it's something to think about for next year.

    a spray with neem oil + castille soap works wonders repelling ants, aphids and mites. though, judging from your photos, it might be very limited in effectiveness. i bought a large spray bottle from the hardware store, mixed up the neem oil (a couple of tablespoons?) and the castille soap (about the same amount - I have a huge bottle of dr bronner's), filled up the rest of the bottle with water, and I keep it out with my outdoor plants. I live in an apartment and the concrete steps are the only space i have to grow. every spring, most anything i grow outside will get attacked by aphids as it starts to get warm. spraying the undersides of all the leaves early in the morning kills them. do it every morning for a few days, spritzing during the day if you see them bunch up. i try not to do it longer than 5-6 days before giving a break from the neem oil. if it ever gets to that point, i take the entire pots out onto the sidewalk and using a gentle jetstream of water, I'll shoot the aphids off.

    flowering plants will generally attract hornets/wasps no matter what you do. but, if you don't bug them, they won't get aggressive usually. and even though they're al the assholes of the air, they are still important pollinators.

    diatomaceous earth works great against external pests like ants too. spread it around in a light dusting where you see them come in, that will work better than making something like a "circle of salt"... ants aren't hollywood demons haha. it'll keep out some beetles too and other critters. DE is safe around your cat too, hell, it's used in baking too.
