Soundproof Sleeping Closure

Hello fellow instructables :) Right I need some help and advice on a design brief to help fix my problem. Problem - I live in a ground floor flat and there is 1 flat above me, 2 scum bags occupy it, a couple of 22 year olds and they have obviously never been taught consideration for others and they bang and thrash around all through the early hours of the morning. When they bang on their bare wooden floor it sounds like a heavy metal dumbbell coming through my ceiling and it wakes me abruptly and its ruining my life :( I've complained to the council the past 18 months but there not interested. They have not put any carpet down in their flat in the last 18 months and it looks like they have no intention of doing so (they can afford fags n booze tho), plus they have a baby due any day now, great.. so now there making their problems, my problem. Solution - The only thing I can think of is making a soundproof sleeping closure, a large box like a 4 poster bed but all sides solid made out of a layer of MDF then insulation then more mdf, but I have some questions before I start. How would I get adequate air in and out ? Would this even stop the banging on my ceiling waking me up ? or would it still penetrate the box ? How would I control the temperature, would it be too hot in there ? Something like the image below but more solid with a door. If anyone has any experience with this or input or any good ideas I'd be ever so grateful. Cheers in advance. Matt

Removing Broken Pin from an RCA Jack

I recieved a free, working TV the other day. The only problem with it was the pin from an RCA video cable had broken off inside the socket. I didn't want to spend money on an RF modulator for my DVD Player, so I figured out a pretty solid way of getting the pin out. 1.) Find a needle 2.) On a hard surface, bend the very tip of the needle slightly so that it forms a tiny barb. 3.) heat the tip of the needle with a lighter until it glows red hot. 4.) stick the needle into the plastic core of the broken RCA pin 5.) wait a few seconds for it to cool 6.) pull the needle out, and the broken tip should follow!

Fishing Lures

After seeing this, it has me wonder if anyone has anyone else experimented with making fishing lures? Particularly, has anyone tried making any unusual fishing lures? With any success? I recall, when being dragged on fishing trips as a kid, that outdoor stores would often have some crazy gimmick lures that never seemed like they would work, but claimed to be the greatest thing that ever happened to fishing since the beer hat. I think it would be a fun challenge to not only make an incredibly bizarre fishing lure, but to get it to work.

Soldering iron smoking? Answered

Hi Guys, I just bought a new soldering iron for the first time. When i plugged it into the wall outlet it started smoking (not alot) well that scared the living crap out of me, so I turned it off. So can any of you guys tell me that should I just dump the iron or is it normal. Please guys help (and there was a bit of smoke near the handle too).

Copper chloride without H2O2-adding?

Hi! I think i will see some PCB-Etchin in the future... So i will need an etchant. Aequous copper chloride was the choice i made since it is a regenerative etchant according to several sources. Now if i understood the chemistry right (Sorry... electrotechnician here), the reaction in theory only needs the oxygen from the peroxide (H2O2) and the hydrogen isnt used at all? Since i only have relatively weak peroxide, i plan on using a bubbler to introduce the oxygen to the copper-HCI-mix. This because i dont want to dilute the acid too much... Will that work? I know that if i use normal air (which has only around 20% oxygen in it) it will take some time... But would it work in the first place? I read somewhere that copper and muriatic acid dont really react in the first place... So if i also understood that right, it needs the oxygen present in the beginning to START reacting... So i think i may go with a contraption like: Plastic container with a bubbler installed (Pumps normal air) Add Muriatic acid to the container Add copper to the acid let it bubble till the copper is disolved Now i have a copper chloride-solution which i can regenerate by adding oxygen (By bubbler or H2O2)?

Multimeter DIY Repair?

I have a Radio Shack digital multimeter, Model 22-174. Since the 10 Amp measurement circuit is not fused I blew this circuit and that part of the meter does not work now. I like this meter and would like to know if I can DIY repair it and what I need to do. I have looked around the Internet and have not found any information including the Radio Shack site. Was looking for the wiring diagram only found a parts list. I hope that I can fix it. If I can fix it I will fuse the test leads (black lead) or work out an internal fuse for this circuit so I don't repeat my mistake. Any help would be nice. Thank you.

50cc 2 Stroke Tuning? Answered

I have an old moped that I got for cheap and I am trying to fix it up. I replaced the carburetor and the new one is a little bigger even though it is off of another 50cc. It insisted on running extremely lean, but I was able to get the fuel/air mix balanced by putting some foil tape over part of the intake to get more vacuum behind it. It will only run right if the exhaust is on so that it is not lined up perfectly with the exhaust port on the cylinder. If the exhaust is taken off it will start first kick, but if it is lined up the way it should be it will not start. I took it off today and when I put it back on as close to the way it was before it would start but is now running very lean, beyond what I can tune out with the carburetor. If I give it full throttle it bogs and has no power, but it has fair power at 1/3 to 1/2 throttle. It also is getting really hot and has absolutely no power once it gets very hot. Yesterday I hat it all just right and it ran with none of these problems except that full throttle was still not where it got full power. Does any one have any ideas about what I have to do to make it run right? Maybe there is no option but careful misalignment of the muffler? --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- It turns out that the problems were that the muffler was clogged, and that it was running too lean at first, but too rich once it warmed up. Thank you for you suggestions.

Hi togetherI want to mod an existing printer (TevoTarantula, non-Pro with a 8bit-Arduino Mega) to a new "brain". My plans on using: Board: Rumba32 (Makerbase MKS Rumba32, https://www.aliexpress.com/item/4000897233366.htm...

Unsure if Makerbase has the same problem. Will see.Anyway: I am unsure if i can get the TFT35 V3 to work with the rumba32.

Number of Instructables Allowed In a Contest?

Hello, Instructables Community! I have often wondered, how many Instructables can I enter in one single contest? Originally when I was puzzled, I googled for an answer and found a few topics from a few years ago that said you were allowed to enter TWO Instructables in ONE contest. So, if it was a contest for, say, "Best Use Of a Soda Can" (I made that up), I would be allowed to enter only two Instructables. However, from looking at contest entries, this is apparently not the case. I have seen members post three entries in a single contest. So, is there a limit? If there was a 'Fishing' contest and I had tons of great tips and diy's, could I enter as many as I darn well pleased? Or would I get told "Nope! No more entries for you!" after having entered five Instructables? Part Two: Question Two: Is there a limit to how many contests I can enter at one time? Can I enter DIFFERENT Instructables in as many contests as I want (I understand that you can't enter the same Instructable in different contests). Thanks for the help!

ATMega328-pu not responding on stand-alone PCB? Answered

My ATMega328 based circuit is similar to the stand-alone Arduino design shown here. However even when I run a simple blink program the LED at pin 13 does not blink and I get no response from the microcontroller. I have tried the same circuit on a breadboard and it worked well. However when I transferred this on to the PCB there is no output. I've checked the continuity and all the coppertraces seem to be fine. I program the chip using my Arduino Uno board and place it in the circuit. This works on the breadboard but not on the PCB. I have attached the pictures of the PCB and a schematic diagram for reference. I'm completely stumped as to what the problem might be and would greatly appreciate any help.

Where to get piezo igniters?

I have several lighters that I still like, either for their design or intended purpose. But over the years some failed to produce proper sparks with the piezo. For some I could salvage replacements from cheap lighters but not so much for the longer ones - the type to get your bbq or oven going. Here the wire from the igniter is in ne long piece going all the way from the piezo, through the long neck to the flame outlet. As the wires in those piezo igniters are aluminium it is next to impossible to attach a longer wire as usually there is no room for crimped connections and the isolation is a problem too. I also have one particular lighter that uses a slightly longer and thicker piezo igniter, the common ones don't work here as they are too short. Adding more support underneath is a no go as the shorter ones have less travel when activated. Last but not least is one lighter that requires a piezo with not just the little metal cap at the end but with a full metal body for the stationary part. The lighter in question does not work with standard types even if I add a little metal strip to make proper contact. Problem is simply put that like this the standard ones arch over and no spark comes out of the wire. So big question: Is there any supplier or Ebay shop where one could actuall see the various types of piezo igniters and order them in small or single quantities? So far I already struggled to find a source for the crappy standard ones and the only one I found wanted to charge $ 2.95 US per igniter plus postage. Sounded a bit greedy to me considering I can buy a complete lighter with it for around one single buck...

Have solar street light, want to use it at Home for LED lights - Help

Hello guys!I am a bit curious if I can do this. So here is the scenario;We have been powering the cow shed - store room from a regular electricity source (220v 50hz AC, India). Recently somebody told us that this is actually illegal as the shed - store room is treated as separate house in itself.The good part is, we have a solar street light (subsidized by govt of India - costed around 5000 INR/ 70 USD). This is before LED's gone viral. So we have a 2g11 CFL (18 watts) bulb. It has worked quite well so far.Its August, it rains heavily in this part of India. So i have been monitoring the time for which the light stays on. In an overcast day (with no rain), the CFL will power up for 7-8 hours and in sunny day its for 12 hours as there is auto cut-off for the street light once its morning.The battery: 12v 75 Ah solar tubular (Its a C10 battery, nothing was mentioned on the label, had to confirm with customer care). I checked voltage using multi-meter; it was 12.33 volts (I think thats 70% charge??) The solar panel: Max rated power (Pmax): 75 watts; Rated operating voltage (Vmax = 17v); RO Current (Imax = 4.42A); Open circuit voltage (21.5v); Short circuit current (4.65A).I plan to add following load;1) Part A: 2 x 7 watts LED AC bulb (B22 connector, standard Indian) - This will remain on the auto-on-off circuit (as the CFL is now) to replace the street light.2) Part B: 3 x 5 watts LED AC bulb (in the shed) + Emergency 3 pin socket for charging mobile phones (Reason: once it happened that my village had a power issue which took a week to resolve! So no charging phones, which means the other people in city were worried as they couldn't talk to their loved ones back home). LED's for couple of hours. and Emergency socket will run rarely. Here I would need an Inverter circuit to convert 12v DC to 220v AC.Queries;1) Is this doable? My battery will be running out of warranty in another month, is it worth the adventure? ( a new battery costs 75 USD in open market :p)2) Is it technically feasible to have this load for the shed? Is the solar panel enough to charge the battery to support this load? I think it can pull it off. But still need an expert opinion. 3) Any recommendations for the Inverter circuit? I will search its equivalent on Amazon India. I also have a car inverter (200 watts) which i used on long drives to charge laptops and DSLR camera - hence this idea of adding an additional inverter circuit. Wont be sacrificing this car inverter, hence a new circuit. Is this feasible?4) Is there any way to power Part B from solar panels in day and battery at night?5)Any other thoughts/ inputs for this project? Thanks and Regards,Vikas M.

Need help in identifying connections for CNC board?

I need help please anyone. I have bought another CNC shield recently, goes by the CNC Shield ver 2.7 name. The board has www.lubandiy.com printed on one corner. There are 8 optical isolators on the board for the limit switches and a socket for a Nano. Also there is a heavy duty hexfet near the laser connections. I am not able to find out much about this board, even though I have asked the seller and even a few other sellers that are on ebay. I went to the website as shown on the board, but it is all in Chinese and after trying to use Google translate was still not able to find out any further information. The board looks well made and seems to have a lot of good features, but lacks the needed info to be able to put it to good use. I am not sure if the board has a laser TTL built in or not, it is possible due to the hexfet being there,  There are two heavy duty connections (two pin each marked + - ) and a small connection with a xh2 socket that could be for a laser or maybe a fan.  Can't get any further info on it. If anyone can help with info, please let me know so I can start to use the board with my machine build. I have managed to program a Nano with GRBL 1.1f and it works OK when testing the board on a dry run, no motors connected or laser.
