Ok so I'm not sure I'm in the good section and it may sound really basic but let's give it a shot.

I'm in a room with poor brightness, only one lamp. Must be an economic one but I can't tell because I know nothing about that. I've got no lampshade so it's pretty ugly. I'd like to fix that.

What kind of lamp should I have ? What lampshade do you recommend ? Where to find those articles ?

For the voltage I'm in EU, it's 220V I think.

Btw I do not have any knowledge about how lamps are working. I forgot...

What type of base does it have? ie B22 E27.

Just get one of these https://www.amazon.co.uk/Philips-Edison-Screw-Light-Frosted/dp/B01HZRNFJ8 it will provide plenty of light for a dark room, I have a 75w LED equivalent in my dining room and it provides plenty of light.

unscrew your lightbulb and take a picture

So, i have one of those 50cc 2-stroke bicycle motors. It has magneto and that's what gives coil energy to generate spark. Do you guys think there is enough energy to spare some of it on transformer+voltage regulator for simple tasks like LED lights or maybe even something heavier like USB charging? Is magneto energy even consistent enough to not overheat voltage regulator on entire RPM range?

What you want is a second charging coil and a battery. These are common on ride on mowers etc. One problem they have is they deliver power in pulses as the magnet passes so you will need something to smooth this out like a battery.
>>
>>1078349
So, connecting to existing magneto (which generates spark power) is bad idea?

I don't know how large those pulses are, but i'm willing to bet that proper capacitor (and couple of zener diodes, basically simplest AC/DC power supply scheme) would be enough.

Hey /diy/.

Trying to set up an old micrometer to do some measurements for school project. I'm using an RS232C to USB connector. (not actually measuring the diameter of a lighter, only used for example)

Only problem is that we need to export the data onto an electronic interface. Figured I could use my raspberry pi using installed Telnet to bounce the echo signal function on the ZMike device.

About how much would it cost to take the layout of a double wide trailer and build a home with standard house building materials?

I own 0.8 acres of land in the city suburb. Was going to buy a Clayton double wide for $68K to put on it but the city doesn't allow manufactured homes.

What are my options now? I don't have much money and buying a log cabin kit would look funny in a city suburb. Is there anything I can do with the land to make extra money to save to build a real house? I only have ~$110K.

Not really. Log cabin kits usually cost about 3x what the price is to put together so that wouldn't work.

I'd live in a van or make a tiny home on a trailer so the city couldn't bitch.

>>1077821
Where I live $110k would build you a nice 2-3 bedroom home with a garage if you already own the land. If, for some reason, that is not enough just build a 'mother in law' unit and garage first.

I've seen some very nice 2 car garages with a one bedroom on top. Or, if you have the space, you can do a garage with the unit on the side. Either way, you can live there until you save up more money to build 'the house' and then rent out the other unit.

Signs of long term water seepage. Not to be a downer but anything you do inside will be a waste of time especially if you want to build a framed wall.

May be ok for a year or so but then the you can have a nice mold sandwich with your 9" VCT tile.

So for the last 3 years, there has been a piece of wire dangling from the hallway ceiling. I can't even remember why, there used to be a working light there, but when the bathroom was renovated in 2013, it suddenly ended up as a dangling wire with no light on the end.

So today I ask my uncle to come around who is an electrician to fit the light pendant in and when he strips the wire hanging from the ceiling he says it is only contains live and earth, with no neutral. He said there might be another neutral wire under the floorboards next to it that isn't being...

>>1077223

Find junction box, use existing wires to pull new complete set of wires.

With GFI it's easy enough to check whether the wire is neutral or earth, just light a bulb with it. If the GFI trips it was really earth.

If the GFI doesn't trip and the light works then one option is to simply ignore it and install the lamp armature without earth (if it's plastic then earthing adds bugger all).

I'm finishing a DIY arcade stick. It's made of cherry wood, and I just put on two coats of Danish oil. The color looks great, but I want to give it a high gloss finish.

What would be a reasonable choice here? Can I just brush on several coats of poly? Should I use lacquer? I do know that the Danish oil needs to be fully cured, so I won't do this for at least another week. I would rather avoid epoxys.

Poly would be fine but what I'd suggest is if you have off cuts just apply to those first and make sure it finishes where you want it rather than direct to the workpiece.

Tru-Oil by Birchwood Casey. It's also a natural oil, so it will bond with the Danish you already applied. However it hardens to a solid coat unlike most other oils. This'll let you sand > reocat> sand > recoat as desired. With good enough sanding (600+ grit) and enough coats you can get it looking like glass if you wanted, or just stop when satisfied.

Note, wipe on the coats gently and don't rub them in, natural wood finishes will dissolve the coat underneath. Sometimes this is good (easy...

you can convert parts into a special file format and get them 3D printed by uploading them to the printer
You can create drawings using every part and have them machined. If you have a shop, you can do it yourself

What glue / epoxy coul I use to make laminated blocks of paper could be worked on to make rings like these -> http://littlefly.co.uk ?

I tried regular paper glue without many hopes and indeed it failed, it has too much moisture which makes the paper wrinky, also doesnt see to reinforce the block much. There are some examples of other people online trying to replicate it, but the results are wayyyy shittier than what the guy in the link does.

Stack paper, clamp, vacuum impregnate with thermoset resin, put in oven, use block of paper/resin composite to make shit.

This is exactly what you need to do to get those kind of results. I did a micarta knife handle out of some old jeans.

Was tempted a few years ago. Instead purchased a 2000USD NC mill with a rotary axis addon.

Still works and the water-cooled motor is powerful enough for aluminum.

I got one of those. It's pretty shit, don't expect to mill or turn pretty much anything on it, not even palstics. However it's nice for drilling wierd parts.

Why are all these external dimmers all for regular and halogen bulbs? I need external dimmers for dimmable E27 LEDs

leds dont work like that, and even if an led is dimmable it will be dimmable like regular bulbs but at a lower wattage which is lower than the usual ranges these dimmers operate with

>>1077714
what does that even mean? when I buy an E27 LED bulb which comes advertised as "dimmable", how am I to dim it?
>>
>>1077716
holy shit, are you mistaking that socket to be where you put in your light bulb? that is a mains socket you dumbass you can plug in whatever the fuck lamp you want

Tesla's latest products are glass tiles that contain solar panels. They look like normal roofing tiles from ground level, but from the sun's perspective they are transparent glass.

Idea being you use them as normal roofing tiles. Then combined with a battery pack. you power your house at night. Whole thing to cost less than a new roof plus decades of electricity.

Thank you for that verbatim regurgitation of the presentation.

When I see some concrete figures regarding cost, yield and lifetime, then I'll get excited.

didn't watch the presentations - unless they are less fiddly than regular panels to install or maintain, how are they different from regular panels except aesthetics?
