I bought a copy of that book off ebay too. I waited around for 6 months til one popped up that was only $30. In the meantime I used digilent's resources.

He wants to know if it's worth getting. Would you share your thoughts on that?

Schools for woodworking are if you want to be a professional cabinet maker or have a lot of time and money to waste.

Like any other skill, the best way to learn it is to just jump in. Get some books at your local library for technical info and watch some youtube videos for hands on info.

I learned in middle school wood shop. That was mostly safety oriented and machine operations.

>>914968
Youtube has hundreds of woodworking channels
Some focus on power tools and some focus on hand tools
What do you want to do specifically?

>I've been wanting to get into woodworking lately but have no idea where to start.

A decent table saw with a cast iron top and a solid fence is the absolute best way to start and will encourage you to be creative, have more fun, and raise your expectations when it comes to your own projects. I played around with wood for so long without one and it was tremendously frustrating not even having a way to make a dead accurate cut. I might have quit altogether.

You can get an old Craftsman on craigslist or what not for $200 or less though honestly sometimes they don't come with riving knives and that's bad news. Basically, just get a table saw with a riving knife.

What the fuck do you mean it won't have a stabilizer?

Ultrasonic sensors suck. Changes in air temperature and humidity result in different distance values. They have crazy sidelobes and echos can cause them to do weird things.

Why don't you get it working in simulation first?
V-rep has a simple to use quadcopter simulator that is damn good.

The stabilizer is a module that allows copters and planes to correct his movement in case there appear some undesired movement. I am planning to work without it, only using Arduino and ESC.

About the ultrasonic sensors, I guess I rushed a little bit without thinking about using IR sensor. But since I am pushing for something really simple that works in a kind of controlled environment, I am not asking for much accuracy. Wouldn't be surprised if in the future I change them in case I get it to work.

I downloaded V-REP simulator. I haven't tried anything yet. Am I supposed to download models of each part I am using? For example, download the F330 model frame for the simulator.

Also thanks for the reply.

Head chopper.

Honest question, do tripfags not know how to google? because I spent two minutes and found what the mechanism was called.

Nothing turns up for Head chopper for me.
Sorry for using the tripcode, I just use it when I make a thread to confirm OP-ness.

idk but cutting bone/shells/horn/etc smells like shit

>>914087
My guess would be the femur of something large, cattle or maybe moose... So you can get a large enough flat piece. Working bone does smell like ass though, like the other anon said.

>>914106
So much this holy fuck it stinks.

Use a flow hood OP I warn you now.

why dress like chicken?
why take off shoes?

can U show the other side?

>>915110
It's an IC (Integrated Circuit) of some kind. There's probably a part number for it if you look on the other side.

>>915110

It LOOKS like a DFN (dual flat no-lead) IC package, but the spacing on the contacts is odd.

Not to mention the package itself looks old as hell.

If you're asking what's in it, I don't exactly know why the fuck you'd expect anyone to be able to tell you that with no visible part number or any other sort of manufacturer's mark.

looks possible to re-solder but not if you're bad at soldering. practice on some broken or cheap electronics and first try to do surace-mount device soldering before your USB port

horry sheet man

you might be lucky and just set the thing on top, and heat each leg a little until the solder underneath melts

otherwise, practice on other shit as above or have a friend do it

first thing is you need solder braid to remove all the solder on the pads and the pins of the connector. this is to make sure it lies flat and fits the hole. next is a fine tip and very fine solder. do the 2 big mounting pads first to center all the pins, then the 5 pins. if you get bridges, remove with solder braid and try again. or dump some flux on the bridge, and heat. flux is magic at removing bridges.

also, know that the little connector will come off again in the future, maybe this time ripping out traces. if it were me, i'd solder a cable on permanently.

Box, stick, and cheese. Put a rock on the box so it doesn't go running all over with the box on it's head.

Your shitty picture is shitty
But if you have room, then a snare
Remove the wire from the back of a picture.
Loop on one end and thread the loose end through the loop. Secure loose end to fixed object
Make it small so only the head will fit.
Alternate method is to add a weight and a trigger
When rat sticks head in snare, it releases the trigger and weight lifting animal into the air hanging by the neck.
A snare is a killing trap, don't use if you have pets.

A 5 gallon bucket, half full of water. An empty soda can, a wire coat hanger, and some peanut butter. Duct tape.

Straighten the hanger as necessary to give you a relatively straight section that's 4 inches longer than the bucket mouth width. Cut this section off. Drill a hole in the center of the bottom of the empty soda can. Thread the can onto the hanger wire, so that the wire serves as an axle. Apply a generous band of peanut butter around the midsection of the can. Center this assembly across the mouth of the bucket. Secure the axle ends to the bucket with duct tape.

Set this rig up in a quiet area frequented by rats, adding an inclined plank from floor to rim for ease of access. Rats run up the ramp, jump onto the can to get the peanut butter. Can rolls, dropping rat in water. Nuff said. It's a proven method, and it's cheap.

eggs
smear it with eggs
if it gets dirty you can clean it by adding more eggs

>>914140
It has gotten to cold for the chickens to lay eggs.. but thank you for a laugh

>>914140
HowToBasic pls go.

Of course. There are many on Youtube and I suppose many more not on Youtube

If you have to ask the question you don't have the skills.

>>914090
does your home have a machine shop? Are you willing to buyfag all the complex components you have no hope of machining? Then yes you can do it!

moar pumps

>any advice?

I'm torn between "You should add a pump to help offset the pressure loss from the length of tube" and "kill yourself".

>>914063
Raise it up above your head on a stand or something. Then you can start a siphon flow. You can place a clothespin on the end to turn the flow on and off. No pumping needed. Make sure to tape the connections well to prevent leaks.

On a related note, how can I extract a seized and slightly stripped 3mm screw?

I'm looking at the #1 grabit which says it works on screws down to 3mm. Will it be able to get out a seized screw? I can't take a torch to it as it would demagnetize the magnet the screw is holding on and quite possibly damage the motor directly beneath.

marine non-metallic is the stuff, it's not the best anti-seize or anti-galling compound but it's the most resistant to warm salty water.

ez-outs are for times when the head is reamed out but the thread is free to turn, if you could only reach down in there and grab it. using one on a seized screw will snap the ez-out off in the hole and then you're ker-fucked. a left hand drill is what you want.

>>913477
Well fuck. Drilling it out would damage the mating threads, right? Because this is in the motor shaft, and I doubt I could rethread it.

>>913353
Start with SMAW...MIG is for unskilled fags and women.

>>913353
See if you can find apprentice/starter kits which have everything bar the welder and wire/electrode/filler, they tend to be a better deal. Also I support starting off with MMA, a decent inverter machine that also includes lift arc support can be had for a good price.

>>913353
only having .030 gasless wire will basically prevent you from doing auto body rust repair and exhaust welding, it just stabs through and makes a lumpy birdshit mess. i'd suggest adding some .023 er70s6 and a non-rental bottle of co2.

also you might want an angle grinder, roughing discs, slitting discs, flap discs, wire wheels, hearing protection, dust mask, safety glasses.

i'd also suggest a fire extinguisher. you don't want your last words to be SHIT SHIT SHIT SHI-
