>>913815 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?
Hy /diy/ , i need some help : I have an MSP430 microcontroller and with a thermistor i have made a themperature sensor . The hardware part is done but now i have problem at the code part , i didn't quite get useful information on the internet and i wonder if you could redirect me on useful sites or give some tips. Thanks :)
>>914331 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 .
>>913914 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?
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?
>>913827 >legit worst answer ever and that google search fucking sucks m80. get gewd.
>>913823 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.
>>913671 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... Comment too long.

>>913671 It's a high voltage transformer... think tesla coil... or like a slayer exciter circuit ionizes the low pressure gas in fluorescent bulbs ... As far as slot machine cheating. I'm pretty sure that it's not gonna work even if you could get something like that to work security would carry you out within 2 min... cameras man :(
Oh I don't have any interest in using them for slot machines spoofing. I just want to bullied them and sell them as a side hustle to my engineering job. A seller on ebay that I looked into made a few thousand dollars selling them in about two weeks.
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... Comment too long. Click here to view the full text.
tested it a bit using the arduino ide. (no atmega, just the esp8255) still haven't used them for something cool yet. i have a big ol' led screen. like 8x96 leds. could be cool to have a screen i could type to over wifi i guess. got too many projects, probably won't happen
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
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... Comment too long. Click here to view the full text.
I wanna put together a Little Free Library and install it somewhere in my neighborhood. The problem is, my neighborhood is in Houston, the most humid place on earth. Is there any way to build a wooden box that will lead to lower humidity inside?
>>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.
>>912379 Just to be sure, you are referring to http://www.vexrobotics.com/276-2168.html Yes, they are on the pricey side, but I think this will work. My only problem is that the tread is not rubberized, and we need good grip on smooth surfaces. Does anybody have experience with 3D printed tracks?
