I recently bought a wardrobe like the picture. Its antique and beat up quite a bit and I'd like to fix it up. Any suggestions on where I can get replacement parts/a new lock and key for the piece of furniture? I appreciate any advice.
>>940987 >I'm planning a custom knife. How do I add serrations to it the right way? knife companies use a CNC grinder. I'd think you could build one for <$200; it would be just a 3-axis positioning setup (like a 3D printer) but with a grinding motor on it instead of a 3d print head. kinda expensive and complicated tho
much cheaper & simpler would be to get a diamond honing steel and use that instead
how do i print my own silver coins? If got this piece of gold, and i would like to make coins. I would like very much a wolf/wolfhead on the coin, maybe a year as well, I planned to use around 8 gramm per coin. The gold is near pure and should be therefore very soft
pic related is from around 500 BC, i Think i should be able to be minimum as succesfull as the dudes back than
>tfw too /sci/ for /diy/ >tfw too /diy/ for /sci/ Anyone know this feel? If I post my ideas on /diy/ people complain it's too technical but if I post it on /sci/ they sperg that I havent used the latest theory.
When I plug my Milwaukee battery charger in at work, my boss' Makita radio goes to static. I've never had this problem when using a Milwaukee radio, and the Makita radio works fine with the Makita charger. So it looks like the switched mode power supply in the charger is causing rf noise that neither the radio or charger has adequate filtering to remove. I tried just moving the two away from each other, but there was no improvement in the sound, so it looks like the rf harmonics are traveling through the wires instead of just through the air. The two work fine when... Comment too long. Click here to view the full text.
Any of you tube guys ever heard of this? The wiki article for evacuation tip (the little wiggly bit on the ends of tubes) mentions something called a "glasshacker", which are apparently people who ...hack vacuum tubes? Is this a real thing? Because I've never heard of it before, and it doesn't seem to be mentioned anywhere else on the internet.
>>940911 It's sometimes done in nixies tubes. You swap out the gas inside it and they change the colour of the glow, since most nixies ionize the gas around the filament to get the glow. So you swap it out for lets say argon and you get a blueish white glow. I've never seen anyone do it but it's possible.
>>940852 So buy a battery box? Should it be ok in the bin I have it in now if I strap it down in my trunk? If so, should I put wood under it? I was always told to do that if I'm putting a battery on the floor. Maybe it's just a myth
Ok, I know enough about electricity to get myself thoroughly killed with it. Before I spend quite a long time trying to research this, possibly getting it wrong, and killing myself, I figure I'll ask someone who knows:
What's an estimate for the lowest price point for the setup necessary to make stuff like pic related? (Safely is of course possible, but that'll be what I look into depending on the answer to the first question.)
>>940827 Kinda... >Many other physicists, experimenters, and artists studied Lichtenberg figures over the next two hundred years. Notable 19th and 20th century researchers included physicists Gaston Planté and Peter T. Riess (mid-1850's). In the late 1800's, French artist and scientist Etienne Leopold Trouvelot, created "Trouvelot figures" - now known to be photographic Lichtenberg figures - using a Ruhmkorff coil (a type of high voltage transformer) as a high voltage source. >In the video a more modern Wimshurst electrostatic generator is used as the high voltage source instead of an electrophorus, as originally used by Lichtenberg, but the principles are otherwise the same. In the video, branching positive Lichtenberg figures are created first, followed by shell-shaped negative Lichtenberg figures.
