Hello /diy/

I've got an Ozito bandsaw. The blade that came fitted has snapped and I'm trying to replace it. I've discovered an issue with the blade guides.

The lower saw guide's roller pushes the blade over a very large amount.

That bearing looks way out of alignment. the blade guides and the bearing all appear to be on the one piece of metal, if the locknut is undone can that assembly be moved to realign it to the blade?
>>
I can only move it backwards and forwards. I can't see how to adjust it left and right.
I've lost the manual, their customer service is closed and their website sucks.

What if I just don't use the bottom guide roller? I'll adjust the other guides very well.

Assuming you will be controlling some HVAC equipment with that thing, how are you handling the higher voltage? I was thinking of making myself a thermostat but my unit is all 120VAC controls which makes it a bitch

The display has 14 pins , it is not like in the picture . The project is not made for hvac equipment , but anyway I used a voltage divider between the thermistor and GND . It will just be plugged by usb in laptop .

Which anti-static foam is better? Pink or black?
15 replies and 3 images submitted. Click here to view.

Black hands down.
>>
>>914205
Has it got graphite in it or somesuch?
>>
>>914210
Probably.
Pink just has an anti-static coat.
This keeps the foam from building a charge but not the component.

Black is conductive and anti-static, which dissipates any charge in the foam or component, as it is hard to have a potential difference, if the whole thing is conductive to itself.

Scrolls saws and jig saws are actually one of the safest types of shop tools. You are very unlikely to get anything more than a nasty cut with them. They don't take off fingers or anything like that. While that diy thing is pretty ghetto its not like its missing the safety gear of a real saw. They generally don't have any. I mean, what are you gonna do, put a guard on it?
>>
>>913914
>>913964
He just needs it clamped and supported better than it already is.

Oh and a guard won't work well because you need to turn the work piece. Unlike what is done with a table saw for instance.

How can I drill a small hole (a few millimeters) in a rock without causing the rock to splinter/shatter?

Specifically, I'm a Runefag and I want to make an amulet of fury (onyx amulet). I have some real onyx that I got on ebay. I have some twine stuff that works to make a necklace out of. I wrapped it around the onyx but I want to do better. I want to loop it through a hole in the onyx. If I use a drill to make a hole, will the onyx crack/splinter? And will it damage/dull the drill bit? Is there a better way?

Thanks

OP onyx only has a Moh hardness of 7.0. Carbide is like 8.0 Clearly you need some sort of diamond bit, or carbide bit. the easiest way would be a dremel and one of those like 13 dollar diamond bits. drill half way on one side, flip over drill to the half way point on the other side. keep going for the hole size you want.

Soon to be graduating engineer here. I've seen hundreds of these devices on ebay listed as "EMP test bulb generators", apparently for testing light bulbs or for electing enthusiast tinkering

Other sights Ive seen openly list them as cheating devices for slot machines. My question is, are they legal? Is there some FCC regulation against them? If so I would think ebay would shut the sellers down, but like I said there's hundreds of them.

Looks like easy money to me, but I wouldn't want to go to prison over opening an eBay store.

Slot machines are computers now. There is no easy sort of manipulation you can do now that won't be detected or just cause it to crash. The only manipulation is around finding bugs in the program that aren't published and are patched quickly.

As far as bulb testers as intended? No idea. They are high voltage low current electicity. Never thought about if they are blasting enough noise to make the FCC care because they are usually novelties and couldn't really be tracked if you're only clicking...

My only concern would be if some dumbass got caught with one in a casino and then having the FBI ask him where he got it from. I assume if they're listed as being for educational or recreational...

You can flash it with NodeMCU or compile a custom firmware. Either way, I've created some automated scripts that build all required tools in a convenient VM. You can find those on GitHub.com/Idorobots/esp8266-ansible

OK, OK. You need a USB TTL adapter, or to piggyback off of an arduino board.

/diy/, I really need some help.

I found this rail and took it planning to skateboard on it. I'm not sure if you can see, but the supports on the bottom of the rail go to one side. It lies down perfectly, but since the weight is one one side, it tips when I try to skateboard on it. What can I do to keep it still? I don't want to keep it one place as I plan on moving it, so I can't lock it into the ground. I have some ply wood, some 2 x 4s, an electric drill with some drillbits, and (really shitty) hacksaw. Keep in mind that the hole on the bottom of the...

Supports directly under each end should help, unless that curved shape does something strange to the FBD. Alternatively the wood and cinder blocks seems pretty foolproof if somewhat heavy handed.

I forgot to mention that making the supports into a more triangular configuration will help with lateral movement but likely will not do much for vertical movement.

Hi /diy/

I have just had a new boiler installed and the wire from the boiler to the thermostat was too short. The installer came round and extended it with a connector like in the picture.

In the UK is this:
-safe?
-legal?

I spoke to him and he said it is a date cable and therefore safe, but I'd like to check. I've not yet paid, should I refuse to pay the full price and get someone else to redo the wiring?

Thanks

*data cable

For reference, he said it is bell wire.

Also, it is NOT in any sort of casing. It looks exactly like the picture.

>>913136
Yes, that is quite fine. If you are still worried, just wrap it with electrical tape.

>>913139

Okay, so there's no worry about fire or anything?

Should I pay full price for the work, or should I ask that they redo it?

>>912905
Perhaps a solar powered heating pad inside and a thermostat? Though, you want the heat inside to be slightly warmer than the outside air to prevent condensation as night. Aside from that, those Indicating Moisture Absorbing Silica Gel things might work well if it is a small area. You'll need to replace them from time to time. Basically you bake them in the oven until they return to proper color and reuse them.

>>
I had a 110V arc welder given to me, used it twice, now it collects dust. It worked well with the remaining specialty rod that came with it, getting that rod was expensive compared to the rod i use for my 220v, and that rod worked like crap in the 110v.

if your going to buy an arc welder get a 220v. if you want something 110v get a mig welder with flux core.

Your rod selection for 110v if it draws 15amp or under is limited and when i looked at it 10 years ago expensive.

Hi /diy/! I'm building a RC/autonomous tank and I'm looking for a good platform to work on.
I found the (pretty popular) Tamiya platform https://www.pololu.com/product/106 but it's a bit small for my purpose. Can you recommend me a bigger platform (15-20cm wide) that is not prohibitively expensive? I do have access to a 3D printer, but I would prefer an off-the-shelf solution.
