Made this dog house for my new pupper last week. Just a sheet of ply butted, glued and screwed together with some tech-7. I put some left over ceder on the exposed edges to stop the rain seeping in and the top is just a piece of counter top I had around. Painted with some external paint to hopefully help extend it's life span. All I have to do now is try and train his dumb ass to go into it.

Hi everyone,

I just bought a old library card catalogue so I can sort and store my Magic: The Gathering cards as bitchin'ly as possible.

I've been attacking the top and sides with Goo Gone to get rid of the leftover packing tape and sticker residue, and that's taking a while. On the bottom is a thin rubber/plastic strip that the university put on the bottom to protect it from the custodians' brooms and mops. What's that strip called? Wondering if I can buy a new strip, or put something similar over it. I could try to remove it, but honestly,...

The strip at the bottom is called a toe kick plate/strip. You can get them at home depot. They are usually pretty cheap, but can be expensive if you decide to get one made out of brass or something.

I just did a search, and I can't find anything as a strip called a "toe kick". The corners are curved, so I can't just cut a piece of board.

>>1051771
above anon is right, toe kick/toeboard/plinth - but its basically just a bit of wood - if thats got rounded corners, its complete custom thing.

IKEA sells standard kickboards, those clip onto the cabinet feet tho. I dont know why you need to remove existing, jut recover in a new piece of vinyl, or replace with new (non-rounded edge) kickboard. Various concepts furthered here:

while your question is slightly convoluted, most of the modern electric on-demand water heaters are great - small, cheap, and hot as you like. Putting one in a living room shouldnt be a problem, as long as its near the water supply?

The problem would be, have you got a sink/drainage already? If not, I'd put in a complete sink/under cupboard unit thing (IKEA-type/cheap), mount heater underneath sink, feed from/drain to your water supply. Thats about 200 EUR/$ or whatever for the sink/unit (or maybe $20-$40 second-hand), another 100 EUR/$ for the heater, and whatever...

Found a 12v cordless drill, battery is dead (according to the "dead battery" led on the charger). I have an old DC adapter that delivers 12v and 2.5amps. The battery charger delivers 7.2-14.4v 2.6A to the battery. Can I use my 12V 2.5A charger to power the drill?

Heh. I was looking at doing this just the other day. The amperage is about half what you'd ideally want, which means you could burn up the power supply if you work the drill too hard so keep that in mind when you're using it. Lookup "cordless drill to corded" on youtube. There were a few vids that show how to do what you're wanting to do.

Sub zero temps won't do shit. Even if the insects themselves die their eggs or larva will survive. Call a nursery or good landscape company and ask what kind of systemic pesticide you need to kill them since they're actual trees. Systemics are drawn up through the roots so they arent a super quick solution but they're the best bet. Also ask whoever you call about how to prune Apple/pear trees to limit limb death and the wounds it causes. It will help prevent diseases and pests.

kek well, I removed the head part and when I turn it on, the "plate" inside the head goes up and down at the same rhythm of the "kicking" sound it makes, though if I don't keep it steady, the whole head comes off and I can see inside below the plate. The "rotor" which pushes the plate up and down is the origin of the sound and it's rotating with intervals, all pieces seem to be in place from here though.

I wonder if it's a problem with the converter instead? the red...

hey diy.

I like this kayak here, but its only rated to carry 140lbs max load. I was wondering if there was a way to increase the max load to 190lbs and not lose any buoyancy?

I was considering opening the seam on the plastic hull and stuffing styrofoam (maybe spray foam) then sealing it back up, but I doubt I could do this and reseal it back to 100% waterproof.

The other idea is make some pontoons for it, but I want to try to avoid making its footprint any larger.

Its a great size for small creeks, any pretty portable. any help is appreciated.

I don't see how putting foam inside it will help it carry a heavy load.

Buoyancy is about how much water it displaces vs. how much it weights. if you want to increase its load size, you'll have to either increase the amount of water displaced (ie. increase its footprint) or lower it's weight. When it comes to boats you also have the whole problem with stability, but that's way harder to tackle

Seriously dude, you just made my day. I've had to explain how some of the floating houses in Europe use huge concrete blocks as a flotation device because of how much water these massive blocks displace for their weight+a house on top.

Buy seeds now OP, everything will be on clearence soon. You can just stick them in any pot with a drainage hole. Fill bottom with pebbles, then some decently fertilized soil, soak, sow and leave in window sill. Touch soil daily to see if dry, then water.

Protip: You can leave the seeds in a glass of water for twelve hours before sowwing and it jumpstarts germination. (Not usually nessisary for herbs)

Source: I do this and I grow; chives, basil, cilantro, parsely, thyme, mint.

What is shit tier?
The internals don't need to be particularly expensive and you can make it cheaper by omitting the volume control. Or you can ditch the RF stuff altogether and make an imitation theremin using light sensors. They're cheaper.

Are the Wen drill presses any good? I've seen them being sold everywhere for around $65.

And are the Olympia 4 inch vises good?

I see them for around $20 all the time.
>>
>>1050151
Nope. They are the same Chinese garbage that every other cut-rate importer sells these days. Wen hasn't actually made their own tools in 30 years.

You might find a better one used on CL for that place. Post the nearest one to you and I will have a look and see what is good. Also, is $65 the upper limit you are willing to spend or can I look for ones that are a bit more?
>>
>>1050151
They're ok for what they are- light duty drill press for hobby work and do just fine.
If you want to spend a bit more money, you can get a Hafco series press which is much higher quality, 16speeds and while they're about 3x the price, they're 10x the drill.

hey there, can anyone give me a hand on using sealed lead acid batteries?

ive googled about the topic but most pages go too in depth or are focused on arger more complex batteries/uses that i have intended. im pretty sure someone here can help me easily.

so i bought a couple batteries like pic related to be used on a portable recorder and also in a diy portable amp poyect im building.

main question is: how should i recharge them? i understand smart chargers are the best but they are abit pricey for low budget stuff im trying to do. i have a 12v 7Ah and a 4Ah (but i also have couple of 6v i got from the trash).

anyway, if i connect a dc 12V 1A adapter straight to these batteries... will that do the trick of recharging them? i read somewhere that i should charge them one hour per Ah capacityof the battery. example charge 7 hours my 7Ah bat. is that correct?

how about using a voltimeter to see when they re charged? what voltage should tell me they are charged? also how much is considered "uncharged".. i used one and after going down 10v it came down really fast to 9v and then my unit could not use it anymore.

also, i understand these bats dont have memory.. so i could use them a bit and charge them etc.. is that good? or should be avoided?

thats it, anyway, any pointer or do or dont you guys could give me would be really apreciated. and also sorry for my b ad redaction and english as its not my main language, im trying my best here, sorry! and thanks :)

Modern SLAs are really, really robust. If nominal voltage is 12V, they should read 13.5-14V when totally charged. Is your 12V power supply adjustable? Don't try to charge a dead battery with 14V straight off the bat, get the voltage about 5-15% higher, let it equalize, then bump it up another 10% until you've leveled them out at the max voltage. It may take quite a while, depending on the output of the supply and the capacity of the battery. If your supply isn't adjustable throw a 50ohm power resistor in series and call it good.

Do not charge them with voltage higher than 14.1vdc.

Is there a way I can put a claw tub like pic related on something it can overflow into? What kind of flooring or whatever would I need to put beneath it?

Just treat it like a shower. Standard water proof tile flooring with tiled wall, grate in the floor with a shower drain.
>>
>>1049890
you do know that the tub has an overflow drain, right?
>>
>>1049972
That doesn't negate the fact that I want it to be able to overflow without damaging anything.

Do you know the name of the algorithm that can interpret audio?
Or anything that could lead me into this, thanks in advance.

Speech recognition consists of whole heaps of common algorithms combined. Bayesian networks, trigram shit, phoneme recognition etc etc. Lots of open source programs for this, most famously Sphinx. Google for the rest.

Music recognition, no clue.

What is your opinion of french cleats?

I tore out the pegboard in the garage (which sucks balls - never do this) and replaced it with a heavy duty implementation of French cleats. So for most of this 3-day weekend I've been dreaming up tool racks. Haven't quite figured out how I want it all organized, but that's the nice thing about French cleats. You don't need to know, just start building racks and tool holders and let it all come into place later.

Just a piece of plywood with a bunch of oak dowels inserted at a 75 degree angle.

Can hold various objects like hammers, etc, and things with holes.

You can see the vise on the left. I'm not sure if I like this configuration, since the cleat gets in the way. I may take off the opposing french cleat from the vise and drill two large holes in the base instead. I would make a mount by making a board with two protruding bolts or large dowels to hang the vise.
