Why does it have to happen from your smartphone? Why not assemble a small server for music streaming in your kitchen?

>>1163769
That sounds like a good plan, I like it.
In my garage, I just use an old smart phone to stream music.

Because I already have all the hardware I need except the Amazon button. I'm looking for simplicity here, I don't want yet another CPU in my house that I have to maintain. My solution is literally "push button, receive music".

>>1163863
If worst comes to worst I guess I could have an old smartphone permanently paired to the speaker, with the Deezer app permanently open. But I'd rather have the "button" solution work - plus it'd be fun for me to build

Tomorrow I'll probably work on the "keel", dunno yet. I have a design in my head. but since that's all I wanted to say, and didn't wanna leave my post short. here's some notes. ;)

gonna need 80 1/8th in strips, @ 38 inches. so an 8 foot 2x4 can be cut in half, to get 4 foot lengths, then the 4 foot lengths

can be ripped into 1/8th inch strips. accounting for saw blade kerf, and trimming the rounded edges, I'll have 13 useable

strips, PER 4 foot length of 2x4. so a full sized 8 foot 2x4 offers me a total of aprox 26, 1/8" strips. to aquire enough strips

for the verticle ribbing, I need x3 8 foot 2x4s.

I didn't see your other thread, what is your overall goal and what are the materials you're going to use? I don't see ripping 2x4s as a viable option. Building a boat around an engine is a good idea as far as design, but are you thinking about maintenance, oil changes, tune ups, exhaust routing, room for blowers etc?

>>1164739
>I don't see ripping 2x4s as a viable option.

I've ripped frames, gunwales and stems out of 2x pine stock and it turned out OK. It does seem that it's easier to find stock with fewer knots in 2x10 and 2x12 than in 2x4s, so do consider doing that when shopping at your local big-box store.

You can ask DJ Focus who started his own radio show in Sierra Leone with a self-built transmitter, generator, and batteries entirely by himself.

I don't know what his email is unfortunately.

Nothing not super invasive is going to stop a hammer from hurting someone. Buy one of those parachute guys and tie it to a hammer, see what happens. The only way this would work is if the parachute was proportionate to the hammer how your army guy is. This would leave a big bulge on the handle, which everyone would hate.

>What is the "fastest" type of parachute design?
One that's already open.
Failing that, ram-air parafoils such as the typical "sport" parachute open very quickly, and normally use risers to slow down deployment of the parachute to avoid injuring the jumper with the shock of a high-speed deployment.
Failing that, reserve chutes are usually designed to deploy very quickly. Most of the designs I see have shrouds going to the middle of the chute (pic related), which makes sense because it holds the chute in a flatter geometry from the outset instead of furling out into an elongated sock before finally expanding out into a dome like a round chute usually does.

You might also want to consider a tailcone or fins like a badminton shuttlecock or the fins on the Panzerwurfmine. Both are very effective at orienting the projectile.

Put a dead bolt and a chain on the front door, it won't stop anyone determined but will certainly slow them down.

>>1163629
alarms and cctv are not permanent items, you can easily just put it on top of a cupboard etc

get a programmable timer switch for lights and a tv so it looks always occupied

also you can put plywood against the windows so it looks blocked off from the outside

other than that, back up your data off site, put valuables into deposit boxes and get insurance i guess

also get a dog

As a security specialist, you should be able to buy a few door contacts and whatnot to arm the place up with, but that isn't worth shit without an outside monitoring company.

Start with physical security, bolts on the doors, strong, hard to pick locks on the front door (you wouldn't believe how easy it is to pick a residential lock), nail or bolt windows shut.

Part two, don't make yourself a target. Make sure valuables aren't visible from the doorway or windows, make yourself as nondescript as possible.

To cap it off I would get a couple of cheap web cams and just set the down in a few spots. If somebody does break in at least you will have a face to give to the police, try to position the cameras in a way that would give you a good facial shot from a doorway or window. You can even make cheap web accessible cameras yourself with line a raspberry pi

Lower screw was bit loose, wire started arcing and the heat burned/melted the plastic?

>>1163265
That is possible, although i dont understand how iz could become lose on its own. I could juts replace the fuse and the wire and see if it happens again.

>>1163263
Is that flex?
Many small stands of fine copper wire?
Breaker probably isn't designed to work with flex and certainly not with such a small csa flex.
Did you crimp the ends?
Crimp some bootlace ferrules on the conductors before you screw them down.
Did you follow the torque spec for the breaker? Breakers often have a torque you have to meet when tightening.
Maybe on the other hand it was too tight, you broke some of those small strands by tightening or when you striped it to begin.
What loads are we talking here, in a greenhouse so heaters? Grow lights? How many amps? Cable looks like it couldn't take more than 4 or 5.

Heat makes metal expand, current makes heat. Cycling current on and off makes the connections expand and contract, they work loose over time, as the connection gets worse resistance increases, heat increases, spirals out of control.

Summary: Crimp on ferrules or use solid core wire. Tighten sufficiently and check tightness periodically.

Yup. Or buy new. Or convert electric. Or buy harbor freight predators

Look for a copy of the service manual, that'll have the info you need. Torque specs, process for dis- and re-assembly, usually a little more in-depth wiring diagrams than the owners manual.

Biggest thing to pay attention to in a 4-stroke is the timing.
My moto (525cc single) has a cam chain, with the piston at TDC there's two marks on the gear that line up with the edges of the head.
Generator (127cc single) has a couple of gears that drive the cam, those gears have one-dot on one gear that sits between two dots on adjacent teeth of the next gear. It can only go one way, but if you're not looking closely you won't see the marks on the gears.

Bolts that are in a pattern (Head, case halves, clutch cover, stator cover, etc) all need even torque. Doesn't matter as much that they're torqued exactly to spec as much as it is that they're all torqued the same.

30cc syringe full of oil is real helpful for reassembling.
Make sure all your bearings are well oiled before putting things together.

Otherwise ... find a buddy that's raced snowmobiles/motorcycles/atvs/etc; they'll have a real good idea of how to deal with a small motor like that.

Nah, that's cool mate. If I can use my imagination that my wand shoots bolts, then I can just use my imagination that my pencil is a wand.

Nice carving work. Have you considered adding epoxy to make it looked like there's a crystal in the triple helix? Probably wounding make sense for a woodland type wand but would look cool in a fancier looking wand.

You'd have to seal the concrete, but it's doable.

>>1162490
Cool, I was wonder how I'd form it. Could I just put plastic dowels from the base to support a wooden form?

Would chicken wire suffice for metal or would I even need that?

>>1162505

Plastic dowels and chicken wire will work. You're likely to spend more between resources and labor doing it this way than buying a generic shower pan from Lowe's though.

We already can observe meteors, the telescope works, we want to automate it so that instead of one person sitting the entire night in front of a screen we have an orange pi do it for us

I think no one reuses the RF shielding when I see these type of projects and I know no one that does a Raspberry Pi version does.

There are computer cases that are made of plastic/plex that has no shielding at all.

If you do want shielding, dont use aluminum foil. It will be a hassle and can end up getting damaged and making a mess. The foil will fall onto the parts.

Years ago I put a PC in a Sun Sparcstation but I didn't reuse the shielding. Had no problems at all.

>>1160832
Generally, most users don't need to worry about RF shielding for PCs. Like mentioned about, they sell plexiglass cases and open cases with no shielding.

I have never seen a PC case thathas that sort of shielding.

Though a lot of cases use the case itself as an earth ground, and a lot of motherboards have contacts that go to the mounting screws for exactly that purpose.
