Hello guys,
I want to sharpen all the knives I have. Normally I use some knife sharpeners from the store, those are abrasive metal plates where I rub the blades on.
But that takes some time. In my grandpas workshop I found this grinder. The left wheel is seemingly out of rubber, but still rigid.
Also I found a green block of something that looks like dried up clay. (more Pictures follow)
Can I use that grinder to sharpen my knives?
And is that green stuff the buffing compound?
A more closer look on the wheel.
And the green stuff
>>918623
Yes and yes. I sharpen lawnmower blades, knives, sickle, etc. on my grinder. I even form stain glass shapes via my grinder. Love my grinder.
Trying to reattac power supply cord to breaker panel in rv can't loosen tight cable clamp nut seen in pic have tried prying with screwdriver
What do
>>918244
Put a big flat screwdriver on one of the little tabs on the nut and hit the screwdriver with something
My ground and neutral bus bar screws are both frozen

Hey /diy/ I'm installing this after market radio into my car. The wires I need to connect have these plastic caps on them. Is is safe to just pull them off to soder them to the other wires. Also is it acceptable to just use electric tape instead of soldering? Many thanks
The plastic caps are crimp connectors, you can just pull them off. Don't use electrical tape, it'll fall apart when the weather gets warm and your stereo will either short out or have strange issues. You should either solder and heatshrink or just get some more crimp connectors.
Just order a piggy back connector from your new radios manufacturer for your car. Plug and play.
>>916919
Still gotta connect the wires somehowbro
i just bought this thing at a garage sale but it needs a new power cable
does anyone know where it goes?
Into the black block behind the trigger. Without more/better pictures I couldn't say for more certain. It will require Live, Neutral and Earth, with a properly fused plug. Metal bodied drills can be lethal if they have a short and dump through the casing.
>>916824
im having trouble finding out where exactly
>>916829
Wires are missing that black box the trigger is connected to would normally have three wires coming out for the power cable. This is a hard fix than just putting in a new power cable. For reference google the manufacturers spare parts list in relation to that model of drill. Hope you didn't pay more than 5 bucks for it cause power drills are cheap these days. Live and learn
hey im a carpenter interested in quirky designs and i came across a piece today by Sebastian Errazuriz called the wave cabinet and im quiet amazed and would love to make it i get most of its design and could probably guess the rest but i want to know for sure how its done.

So this is something I was looking into, just in the initial planning stages now, and its probably a long ways off but here goes.
I want to build an airplane.
A hummel Bird, or Ultra cruiser to be precise (pic related)
So what kind of tools would I need?
Floorspace?
What ways could I could cost effectiveley practice riveting and sheet metalworking in the next few years leading up to the project?
Final question: Are any of you aviatorfags? (Preferably of the self built or atleast DIY maintenance variety)
Its been my life dream to build and...

Where are you anon? Do you at least have a light sport (LSA/RA-Aus etc) license?

>but I feel like I might be missing something.
A pilots license. That's the hardest part. Mostly just getting the flight time with an instructor you need.

There was a guy who was slowly building a plane throughout my elementary school life, roughly 5 years. I used to walk by his place everyday, and he'd be working on it.
I got to see inside his garage once when a friend I finally spoke to him, he had all sorts of tools, that I would later recognize life.
Tools that stuck out were an english wheel, air tools, an array of wrenches and socket sizes, a welding machine, TIG, organized blue print reading board, I guess it took a lot of work.
My guess is it would...

>tfw don't know which direction I need to turn screw
>tfw don't know difference between watts and volts

I am no man.
>>915206
Most screws are clockwise in, counterclockwise out
Watts are volts times amps
Changing a tire is 4-7 nuts, just like you did the screws

for screws, leftie loosie, rightie tightie. leftie is counterclockwise
I'm looking to purchase a house and contingent on FHA financing rules the existing detached 2 car garage is too far gone for a quick fix to make it legal again. I'm being told the only quick way to make it work is to tear it down.
It was built on a slab and closer to the property lines than current regulations allow. Tearing it down and putting it up again would mean I have a smaller (width) and shorter (height) garage than was there since it was grandfathered in. Plus it would need a a full foundation which requires a massive amount work and money on our end.
I'm...

just replace all the wood and siding except one wall then wait a few years and replace that wall if possible
your local laws my very considerably and no one knows because you did not post location
>>915124
it has to be addressed before financing is approved and the existing owners are too old to do anything about it (like deathbed old)
It's located in Massachusetts, it's not just 1 wall its the wood around the base of the garage. It's rotted because the previous owner just tossed his yard waste behind and against the sides. The roof also is about 3 layers deep.
Ripping it down means it would never be able to be rebuilt with the same dimensions or in the same exact location. I read that...

This is how we get around the rules for how close you can build a cabin to a lake here. You buy an old run down cabin, and use one of the walls to build the rest of the new cabin on.
Please help with concise directions on wiring in Bluetooth and custom keymapping programming code (ie momentary press layer) to Hand Wired Mechanical Keyboards with Teensy.
Forums are inundated with embarassing toy keycaps and digressions about gold springs.
Would love simple diagrams and videos of what to wire where for Bluetooth onto a teensy and examples of coding options.

Is this a substitute for a Teensy? My board only has 11 switches. Can I go even cheaper?
why not just take apart a thrift-store keyboard that has the functionality you want, and recreate the matrix with your own keys?
Can /diy/ make their own reamers, drill bits, tools for boring? I want to make firearm barrels
> INB4 /k/
Of course you can make your own tools. A reamer is pretty easy depending on the precision you want get a piece of tool steel round stock the diameter you want and truncate the end into a tri pyramid or four sided pyramid vola simple reamer. Drill bits you are probally better of buying one a size smaller than your reamer size. If you want on youtube theirs a channel by clickspring he makes clocks but quite a few custom reamers end mills etc his videos are quite good.
>>910372
>tools for boring
Easy. Tools for rifling: more difficult. It can be DIY, but it depends on what sort of production quantities you want. For a few parts, a high speed steel 'button' can be used. For production quantities, tungsten carbide will last longer.
You can do lots of things with android phones, although sometimes you need to root them:
- Security cameras (not quality cams, though. also, not useful at night),
- Some kind of sensor,
- Tracking devices,
- Wifi repeaters,
- ...
Smartphones have:
- Wifi
- GPS
- Touchscreens
- Cellular communications
- Internet
- lots of storage space
- Good amounts of RAM
- Good enough CPUs
- Good enough GPUs
- Great software ecosystems, with lots free or cheap software
and are cheap.
You could even install and run Linux on them,...

You can't really dismantle and part them out because its all surface mount. If you can invent a smelter that can melt them down and separate all the minerals out into nice tidy piles you will be wealthy.
Also batteries, most are disposable by design so power supply is a problem down the line. Planned obsolescence they call it. then again, watching the degradation of windows retro tech may become more valuable as spook and backdoor hardware becomes more ingrained in the industry. These are sad days for tech really.
>>917741
Yeah. I meant, hardware hacking as in using the hardware for things that were not their original purpose, but you don't even need to dismantle them to do something useful, you can take a phone and use them for other things without even touching the internal parts.
As I said, you need to root them most of the time. Even then, looks you can run a fake root and run programs:

So, what can be done with android hardware?
To start, you can find a shitload of ideas by simply googling:
https://www.google.com/search?q=creative+uses+android+hardware+or+phones+or+tablets
One can connect the phones in a network, through USB ("reverse USB tethering": https://android.stackexchange.com/a/6480 ), and use them to process data in real time, from pics, videos or whatever. The phones could be used as wireless APs for small rooms, and even used to locate people in a small room, something like
http://www.securecare.com/healthcare-rtls
(although I guess this needs special drivers that support monitor mode). I also wonder if something like this could also be done:
http://news.mit.edu/2013/new-system-uses-low-power-wi-fi-signal-to-track-moving-humans-0628.
The mics/camera/accelerometer/gyroscope could be used as sensors for many things, and one can collect LOTS of data, etc. For example, I just found this other weird use for the magnetic sensor:
http://www.technologyreview.com/news/428494/startup-uses-a-smartphone-compass-to-track-people-indoors/
https://vimeo.com/107898476
and I read months ago that geologists were using cheap phones to detect and collect data on earthquakes:
http://www.usgs.gov/newsroom/article.asp?ID=4189
On a related note, I learned a while ago that in android phones, the headphone jack can be used as a serial port:
https://web.archive.org/web/20130608093900/http://robots-everywhere.com/re_wiki/index.php?title=Serial_on_Android_using_the_audio_port
https://play.google.com/store/apps/details?id=re.serialout
https://www.youtube.com/watch?v=PfSSPTtacnk
So yeah, you don't even need to disassemble the phones... and the cheapest (new) android phones cost less than $50. Imagine buying lots of these phones, used, for $5 each. Much better than buying Raspberry Pis, IMO...
Are there groups/forums dedicated to this?
I made this thread because I really wonder if I could take advantage of the cheap hardware to get out of my shitty situation.
Do you think a track saw can be a real substitute for a table saw?
>>917065
No
>>917065
have a look at the triton work bench can pick em up second hand cheap and just need to attach a circular saw. Not sure how popular they are in northern hemisphere
![16410-E[1].jpg](https://i.imgur.com/QvzlDGv.jpg "16410-E[1].jpg")
>>917065
Nah. A table saw really is one of the cornerstones of a woodshop. Tracksaws are just a circular saw on steroids. If you need a basic, bulletproof table saw cheap just get an old 1960s or before Craftsman cast iron benchtop sawsaw. You can sometimes get them as cheap at $50 with a motor. That will get you started. No need to spend the big bucks on a cabinet saw if you are just getting started.
>>917070
Black and Decker used to say you could do basically the same thing with a Workmate. I'm guessing the two have about the same level of usefulness.
How to build a small scale wind turbine?
How to use Google?
>>917354
>How to build a small scale wind turbine?
Step 1-
"Invent small scale wind"....
>>917354
How small?
For building a wind turbine you need some magnets, copper wire, and metal/plastic/wood for building the blades, stand, and mounting.
Small scale won't get you much though. You will also need to get it up high into the air to get decent average wind speeds. Just putting it on a roof of a house isn't high enough.
Let's say I'm a semi-skilled welder. Let's say I want to make money.
What could I fabricate on a shoe-string budget with basic welding equipment that I could sell that peeps will want to buy?

Dildos. Use some round blank stock, cut it to size, weld 2 nuts to the end. Voila! Oh, and then put it in your butt for safe keeping
Heavy duty tomato cages out of rebar. Any dipshit can build them and I made them and sold them for 25 a piece. They were made with a 70 buzz box

Can you guys help me out?
I just moved into my new house in Minneapolis, which was built in 1939. I have this switch in my kitchen and I can't figure out what it's for. Underneath the metal cap, there is a spot to install a small lightbulb. Does anyone know what this does, or what it was used for? When I turn it on, nothing happens.
>>916979
what do the wires on the back look like?
....never seen one before.. but if I had to guess maybe the switch is for lights elsewhere in the house and the small light on the plate is to let you know that they are on...
>>916979
It is a light to indicate the switch is on.
>>916990
yes, typically a garage light.
