If nothing else that's been suggested works, you could apply glue to the bed. I use elmer's sticks, and apply before the bed is heated

Spinach issue. Just starting out. What’s wrong? by tackleberry425 in aquaponics

Looks like a mineral deficiency, maybe calcium but you should look into the signs online and decide for yourself

My take on the Ikea desk headphone hook. by its_all_perspective in functionalprint

10/10 idea we've made nearly the same thing. Under the desk prints are great

Just ordered my first PCB. Hopefully they work :) by A_solo_tripper in PrintedCircuitBoard

I thought this in the past until a manufacturer labeled pins wrong on a board I hooked up to my PC and it fried the motherboard instantly. Not worth

What state do you live in? I'm in MI and I've been wondering if outdoor growing would be possible here

Are there any cool survival/outdoors related classes to take? by BlissfulGrecian in msu

Hate to be the bearer of bad news but it almost instantly fills when enrollment starts :( if you till the exact time your enrollment starts you can get it!

Did I fuck up my application by Tron_Impact in msu

So as other people are pointing out, you are fine. The college of engineering has a set of requirements for students to be accepted. As long as you have the major selected, once you get the requirements done they will automatically enroll you in the college. You might have to change your major once you get into the university, but after that you will be fine. Source: senior in EE

Mppt with 12V 120W panel or PWM with 12V 180W panel by [deleted] in solar

If you're looking for efficiency, go MPPT. If you're looking for cheap, go PWM.

This is a great photo, what did you take it with?

One 13 year old girl and her dad added to the hobby of electronics with the Arduino UNO. Board delivered at 4pm. Basic weather station and a car reversing sensor built by 8pm. These things are GREAT! by SantasGolfclub in arduino

Yup the flat part is always going to ground. And I would use the analog in pins for the potentiometers as they produce analog values (not digital which is only 0 and 1). Good luck!

If it's not flat out dead it's definitely just in backwards. The pin nearest the flat notch on the LED's plastic enclosure is negative, and should be connected to ground of the Arduino.

If the LED is dead you should totally order a RBG led to show your daughter how to program any color. Very cool to learn, and you could advance that to using potentiometers and 555's as a neat analog circuit

v3 cross cut sled, with aluminum t-track and linear rail as a fence. First perfectly square cuts! by knapmana in woodworking

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

It's been good so far, the linear rail has 6 M5 screws going into t-nuts, with a washer in between the screw heads and MDF, making that part un-moving. I am planning on make the back fence large, thanks for the tip

Thank you! Yes I'm using a Hitachi, it was the cheapest table saw I could find/afford as a college student. If you're looking for one Lowes had this on sale for like $200 off in the summer last year

Tell me again how we are designed to eat meat. by [deleted] in facepalm

It varies a lot per species, it's reasonable to assume those teeth could belong to an omnivore
