Welcome to /diy/, a place to:

Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.

Please keep in mind:
- This is a SFW board. No fleshlights or other sex toys.
- No weapons. That goes to /k/ - Weapons. The workmanship and techniques involved in creating objects which could be used as weapons or the portion of a weapons project that involves them (e.g., forging steel for a blade, machining for gunsmithing, what epoxy can I use to fix my bow) may be discussed in /diy/, but discussing weapon-specific techniques/designs or the actual use of weapons is disallowed. Things such as fixed blade knives or axes are considered tools, things such as swords, guns or explosives are considered weapons.
- No drugs or drug paraphernalia (See Global Rule 1). If you want to discuss something that could involve such things (e.g., carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.

Some friendly suggestions for posting:
- First ask Google, then ask /diy/. Your question will probably be better received if you do so.
- List available resources (tools, materials, budget, time, etc.)
- Try to use pictures and explain the goal, if possible
- Be patient, this is a slow board; your thread will be around for days.
- Share your results! /diy/ loves to see problems solved and projects completed!

I've got a metal storm door and the screws no longer hold well enough for the closer - they get loose every couple months if I tighten them. I took the closer out and it looks like the previous homeowner had this problem and just drilled new holes. I don't feel like getting all new storm doors, and drilling new holes is stupid. Is there a way to get these screws to grab more permanently?

You can use a digital pin. If you want some more robustness, and an is buffer / not gate with hysteresis.

NiCads are absolute horseshit. It'd be easier to buy a battery and charger, and wire yourself a holster to make the battery go in.

NiCads barely last a year or two, I'm lmao'ing that even fucking Dyson uses NiCads. I think NiMH might be compatible with NiCad charging circuits (current based that trickles off above about 1.2 * pack voltage)

Also, never smell an exploded NiCad pack. Enjoy ur heavy metal poisoning.

a slightly unusual application, but ok
a comparator or two + a pair of p-ch MOSFETs ought to do it. choose comparator for low power and push-pull outputs, choose MOSFETs for low Rds(on) and low Vgs(th), the AO3401 would be great if you don't mind a SOT-23

why would you be using an analog pin instead of a digital pin with Schmitt trigger?

it's an optional safety device. the 10K makes sure there's little or no DC voltage going to the pot. in this way, if the pot is temporarily disconnected by vibration, or whatever, you wont get a loud DC pop that could blow a speaker.

Malt and dextrose won't give it the bitterness. That's what hops are there for. It'll probably be more like malt Mead. If you pick up some hops, turn on your kettle and pour out a cup of boiling water with the hops in and let it cool to room temperature with a cloth on top, then toss it in. Should be enough to lightly bitter it.

I just /firstbrewmead/ too; started with 4lb honey in a gallon, smackpack champagne yeast, wyeast beer nutrient blend. I fucked up the other way (pitched yeast in fridge then added cold pitch to room temperature must) and ended up with a drinkable, albeit sweet, alcoholic beverage. Next brew I'll get a thief and hydrometer.

howdy senpai. After working for several years for the largest fermentation company on the planet (industry leader in biofuels production), I've finally started to try my hand at home brewing.

First 1 gal IPA turned out great, despite underdosing the priming sugar

second batch got greedy and went for a 5 gallon batch, fucked it up and got it infected. Had to toss the whole thing.

Third batch tried 5 gallons again, going for a lager and I think I finally nailed it. pitched on 5/5 and fermentation is juuuuustttt about complete. managed to find a costmetically banged up fridge for 50 bucks - can't wait to keg this baby.

4th batch I went for a plain jane mead - tried my hand at making a yeast prop, totally fucked that up so I just pitched some dry cider yeast lol. Took them a loooong time to get munching but they finally took off and that ferm is on its' way - tasted it the other day to make sure it wasn't infected (as I'm super worried about that after the bad 5 gal batch now) but seems great.


I do have a question though - has any one here tried their hand at malting their own barley?

I had to take it off to clean it anyway, now I have the numbers so it's just making the model. I probably won't model the clamping mechanism because it's complicated and I can't take it apart I think, I'll take pictures and post some rough measurements of it.

Well I guess everything gotta start somewhere...

As I said MANY THINGS CAN BE BUILT JUST AS WELL WITHOUT CLAMPS, not everything. People on this board can not read. If you mean, laminating for thickness, then a press is ideal but most of us have to make do with clamps, laminating for width can be done without camps quite effectively with wedge and or rope.
>>1613156
The other low bench anon here, mine evolved from a standard saw bench, legs on one side are vertical and flush to the top, there are peg holes in one leg and a pair of holes for a hold fast in the other so I can clamp wide board securely at a good height for working the edge. The leg with the hold fast holes is also extra wide so I can use them for holding work vertical with the hold fasts. The vertical legs also make some ripping and sawing jobs easier, like taking a half inch of a 1x12 or the like, Other side the legs angle out at 10 or 15 degrees or so to give me stability. Few holes in the top for hold fasts, stops, pegs, deep narrow birds mouth in one end and maybe 8" overhang on the other.
>>
>>1613123
Thanks man, will do that next time. I just sanded it first with 60 grit and then used a belt sander with 100 grit to kind of flatten the pins together with the flat face of the saw and finished it off with some sandpaper strips to try to get the roundness. I know its kinda thin, I followed a template I downloaded and changed it a bit but I left that thin part alone. For now the thing feels sturdy enough to withstand sawing. I guess we'll see how it holds up in the future.

>>1613156
It’s pretty much the Estonian with a 2”x4” notch in its long edge that I use with wedges as a vice.

If you’re into preindustrial woodworking I can’t recommend Woodworking in Estonia and Ingenious Mechanicks enough. They make for a great collection of old techniques that are next to impossible to put together yourself from the internet.
>>
Biggest problem I'm having with this hobby isn't even the learning part. It's affording material to practice with. Since I'm not making things to sell I end up fronting the full cost of whatever I choose to make which forces me to space out my projects quite a bit. Any mistake made resulting in scrap wood directly hits my wallet as well.
>>
>>1613318
I know this pain. Even on simple projects, progress is slow, for fear of having to start again. Even if it's just a half sheet of ply, that's 30 bucks I dont have to spend if I dont fuck up. Makes it really hard to push forward because I'm afraid I'll want to make changes to the design half way through and have to scrap the current peice.

There's a small place far out in the Atlantic Ocean that, according to height data, is almost exactly sea level. Google Earth says "0m" for most of it, though I don't know the level of accuracy or what tide that's at.
Fine details aside, it's about as close as something can be to being an island without actually being an island, it's presumably wading height most of the time.

Also, as an extra bonus, it's pretty close to an important shipping lane (shortest path around Africa comes very close by)

So, given a small shipload of supplies, what would you make?

The tide in the middle of the ocean is just a gentle rise and fall, they are a non-issue, waves will be what fuck up anything you build on it. Not easy to build something that can take 30 or 40 foot waves sweeping over it for 6 hours.

3rd party seller. I already contacted them and they're issuing a refund which is kind of annoying since I'm probably going to re-order it from them since they're the only seller that doesn't mark-up their tolex 200%.
