Hi /diy/,

I want to turn a sneaker, like pic related, into a hidden camera. I need to incorporate a small pinhole camera into it and make it undetectable to the eye and touch of the foot.

Any advice or ideas?

I want to fully automate a greenhouse with electronics so that we have to go work on it as little as possible. Here's what I'm thinking:
-temperature control with a temperature sensor and exhaust fan and heater switched by relays
-humidity control with a hygrometer and humidifier on a relay
-watering either timer based or with moisture sensors in the pots. A solenoid valve opens or closes water flow, with splitters to each pot, so that all pots get the same amount of water
-nutrients with some sort of container with a mixing mechanism, perhaps a chemistry stir bar. Measure out nutrients from their bottles with strain gauges measuring weight, or flow sensors in the pipes. Open and close with solenoid valves

What else do I need to account for? Is there a better way to do any of this?

It's all going to be run off an arduino. I've got enough experience with the electrical side of it that I'm not worried, and I have a friend who'd be good with the mechanical aspects. But I don't really know a damn thing about gardening.

It's a small grow, <10 plants, all from the same seeds, in individual pots.

So guys I'm trying to ease my way out of tent camping since I've been doing it since the first grade. I don't have enough money to buy a camper or cargo trailer unfortunately so I want to make my truck bed like a camper. I have a large bed since I drive a 2000 f250 so room in that area shouldn't be too bad. I do however have a tool box and a gooseneck hitch in the bed of my truck to work around. Any ideas besides buying a camper too? Pic unrelated

I was wondering if /diy/ could help me. I want to do something to a wood framed structure that will cause some damage but kinda on a delay or take weeks to have a noticeable effect. Like a slow rotting of the wood or something like that. I don't want to make it fall, I just want to make local damage that will be expensive to fix. I though of letting lose some termites. Being the south, termites are a problem here and won't look like it was caused by a human.

Buying 33 acres of land to homestead on. The trees were harvested about 15 years ago and now have some decent growth. My current plan is as follows: Clear cut the whole thing to make room for planting crops and building a masonry home(using the abundant amounts of stone) and septic tank on the land and use the profits from clear cutting to pay back the loan faster.

Thoughts? Should I instead try to forester the land or orchard some trees like walnut? Near TN for the record.

Hi there,

I'm living in a densely populated area (direct visual connection to ~300 units in less than 50m distance), and I have an old linsksys wifi router lying around.
I would like to turn it into a broadcast device, which could act as some kind of "open captive portal web server" which would give access to local information, freely, without connection to internet. Difficult to trace, completely anonymous.

My first thoughts are to hook it to one of those small comps (arduino ? pi ?) turned into a captive portal/server. The whole thing would be consuming little power, and could be plugged anywhere, broadcasting on an explicit SSID.

Just a pirate broadcast web server. Not interested in viruses/scams/whatnot.

Isn't this already done ? Is there a name for that ? Do I have to start from scratch ?

Working on building my own quad-copter.
Have any advice on solving or avoiding common
problems.The basic idea is to fly and
have the camera gimbal mimic the head movements
of the pilot wearing a FPV headset.

That picture is my current progress.

So I want to try freeze drying things. I'm not a prepper or a taxidermist, really I just want to have an unlimited supply of astronaut ice cream.

Guides on the internet all point to freezing your food very cold using dry ice, then pumping the air out so the water all sublimates out. I'll figure out the vacuum canister, but I really don't want to have to buy dry ice every single time I do this. So here's my idea:

Get a big deep freezer, the kind you can fit a deer in. Get a mini-fridge. Disable the thermostat in the mini-fridge and replace the refrigerant with ethanol. (freon freezes at -45c or so) Put a vacuum canister inside the mini-fridge, put the mini-fridge inside the deep-freeze.

Would it work? I'm mainly worried about the mini-fridge's compressor's lubricant freezing, though I'm wondering what else I should be worried about. I've tried googling, but all I get is people asking whether they can store their fridge indoors.

Bracing for obligatory fridge-ception and yo dawg jokes.

I've been wanting to build a bed loft. I want to keep my work area under it, and having the bed on top.

I don't normally do DIY stuff, but it's something I really want to get into doing more. How difficult would something like this be to do? I could possibly have my brother help me, who has a lot of experience building houses and stuff like that.
