I want to connect some fluorescent bulbs and I need a help from an electrician.
I want to make an indoor greenhouse for growing seedlings. I have a building with big windows but they are blurred and not enough sunlight can enter inside. I want to build a fluorescent bulb based grow lights. I need those bulbs need ballasts and starters but I can't find any info on connecting a lot of bulbs.
Picture related is what I want to do, but on much larger scale, I want to have 50-60 of 1.5m (4,9feet) bulbs working at once. I don't want to buy assemblies because... Comment too long. Click here to view the full text.
>>925362 Easiest way? Get blue and red 12v led strips. I'm not aware of a system that allows multiple bulbs to be run on the same ballast. Basically the bonus circuitry in the ballast and starter just start and keep the arc going. So you kinda need one thing per arc you want to maintain. So I guess you'll just be buying 50x 50$ assemblies if you're set on fluorescents. How much of this have you done before? Start small first. Don't want to blow a few thousand dollars on a setup you'll get bored of... Comment too long. Click here to view the full text.
I'm at work right now. I spilled a cup of coffee across a three level glass cabinet/desk. I've managed to clean the most of it up, but there are little nooks and crannies I cannot possibly get to (without completely dismantling the case, which I cannot do, as it is not my property and in a public place).
My problem lies in that although I can't see anymore spilt coffee, I can certainly smell it. Which isn't awful right now, but I imagine will be once it goes rancid.
What exactly can I do about... Comment too long. Click here to view the full text.
Hey /diy/, electricity theory question time. The diagram a) on my drawing is a parallel electrical connection, apparently the proper, safe way to connect few things (like 5 30watt cfl light bulbs in a bulb sockets in this case) to one plug (a 16 ampere 250 volts one in this case). Now I was wondering OK but it's shit loads of additional cables and connection blocks... So... what if you would make a connection where you would put more wires into one block socket [like on diagram b)] and then eventually connect the blocks with just one cable if needed. Would it...

Either way its fine as long as you don't overload the current rating of the terminal blocks and they are large enough to accommodate ask of the wires safely There should be no exposed conductive parts and remember to crimp a ferrule over any multicore cable that you are clamping in a screw terminal
b) would be preferred because there's less wire carrying the full load so smaller wire could be used after the initial run from the plug and the connections wouldn't carry as much. Doesn't really matter though if you use heavy enough wire and solid connections.
Both cases require the wire from the plug to be able to power all the lights. on (b) the next sets of wires only carry about half. The downside is having to connect so many wires together
Define 'charger' for me, because I'm envisioning some wall-wart that maybe has a single diode for rectification and maybe no filter cap at all.
You need a full-wave rectified supply with a decently sized filter cap for audio amplification applications. Preferably an LC filter in it to make it as smooth as possible. Don't ask me to draw you one you can google it.
A charger outputs a voltage higher than the battery, and will usually pulse the voltage because this lets the battery get to a higher capacity and is needed to check the battery voltage to prevent overcharging in some designs. This means the equipment you have connected to the battery is jumping back and forth between the battery voltage and slightly higher charger voltage.
Adding a lot of decoupling capacitors will help a little, but the better solution is an LDO voltage regulator between the battery and equipment. The voltage output of the regulator will be constant... Comment too long. Click here to view the full text.
>>926212 A few layers of heatshrink tubing should do it, as long as it's soft enough to conform to the string (preventing buzzing on the frets) you should be golden. I can't see you paying more than a dollar for it.
I have a boss ME-70 and I'm running it with batteries. Idk if I can make a power adapter or buy a generic one, one time I read somewhere that if I use a generic it can overheat and it's better use only the official boss power adaptor.
The pin in circle 1 has been loose for a while and a rubber band around the plug is no longer doing the trick. I know how to solder and I have basic tools but the plate I'm guessing the connecting pin is actually supposed to be soldered to is loose.
If this is not easily fixable my idea is to simply put a ½cm wire between the pin and the capacitor (circle 2) but I'm not sure how to follow the lines. Is it just connected to the right one, both, or does it actually just run past to something else?

I just bought 2 of these 600CFM inline fans to move air from the top of my paint booth in my garage, through two home furnace filters to stop any particles than outside. My old ones were starting to get old and clogged up, I guess I got the wrong CFM as last time and my new ones are blowing too fast. I unfortunately cannot return them
Is there a way to run them at a slower speed? They are 110V
Hello /diy/ i'm planning to make a few custom power banks. I want them to be as small as possible. Can someone guide me where to find most reliable circuit boards? I don't mind the price, but the only place to buy them from looks like Aliexpress or other Chinese stores. Not that i think that they sell crap but its hard to trust reviews posted there. I'm planning to use single protected 18650 battery for each one. Maybe someone knows reliable manufacturers or ect? Thanks in advance.
Buying an 18650 based powerbank will be cheaper, safer and more reliable than anything you could bodge together yourself. It will also be smaller than anything you can throw together. Nobody will suck ya dick because you went through the trouble of making your own. (Not that you could do that anyway, since you're here asking dumb questions)
>>925437 >/diy/ >someone wants to make his own power bank >hurrdurr you can just buy it cheaper that literally applies to almost anything on this board. Just get out or stop giving shitty useless 'advice'.
I had an alcohol fuelled breakdown on New Years resulting in:
1. A hole in my wall 2. A hole in my bedroom door 3. A hole in my closet door 4. A gouge in the wall
I'm just wondering what the best way to get this damage fixed would be. I guess a plasterer can fix the hole/gouge in the wall, although perhaps this is something easily fixed myself? It's not something I've ever done before.
For the bedroom door I'm almost thinking it would be easier to just buy a new door than try to repair that hole. I'm not quite sure what... Comment too long. Click here to view the full text.
Please help me, /diy/ this is very important and I have no one else to ask. I'm on my own with this.
pic is a quote I received from my contractor. It seems very overpriced but I have no bases off that.
This is for my first condo that I purchased 1000 sqft. Closing will be in 2 weeks. I already purchased the flooring (laminate). The quote includes the paint that will be used. The mirror that is mentioned is a giant mirror that takes up an entire wall. The contractor will remove it. He is including two used (but clean!!) toilets.
Thank... Comment too long. Click here to view the full text.
>>925121 he's including the toilets though. Isn't $180 worth it for toilets and installation? I'll probably remove the carpet myself. Is that difficult? Where do you see floor molding being charges twice? He's charging me got installation and painting. I'll definitely do the outlets myself and the mirror seems to be attached to the wall which might include some sort of cutting/tearing to remove. I might need his help to do that.
3,275 for paint? Is this gold flake paint? Personally if it were me, I'd let him take care of the flooring and electrical and paint it yourself. Invite a few friends over, but then some beer and pizza and save yourself about 3 thousand dollars. Also what does the "repair"ing of the wall entail? Is he installing new sheet rock? Is it just patching up some holes?
Hello /diy/ i have this beast: Conion C-100F and i'm thinking of modding it and replace the top deck with a bluetooth/usb player I dont want to change anything cosmetically I will hide the usb connector inside the cassette port and repurpose the cassette buttons to the bluetooth speaker buttons I'll buy a cheap bluetooth speaker and crack it open and transplant it inside and connect the btSpeaker lines instead of the top deck lines Is it possible? I dont want to ruin my boombox also i want it to have more functionality
The buttons on a tape deck aren't simple pushbuttons. It's a fairly complicated mechanical system: Play button pushes the head into place and locks the eject button. Stop button pulls the head back and unlocks the eject button, etc. The actual electronic buttons are buried in the mechanical apparatus, so you can't just strip out the mechanisms and have a regular set of buttons.
You'll have to completely remove the tape deck, salvage the plastic bits that go on top of the buttons, then put those on a new set of pushbuttons on a new circuit board.
Hey guys, I was just curious, anyone else into watches? I recently found a few old ones desperate for a repair and polish. I have the repairs finished but have absolutely no idea how to polish watches or where to start, anyone able to help?
