Recent answers not updating properly

Not sure if it is bug but IMHO it qualifies: When I update the forum section I see that the number of replies changed if they did. But in the Recent Answers setion nothing happens. Even after several hours I don't see the number of replies changing, despite quite often already showing a few when checking a question. Apart from that the number count in both the forum sections and the ansers sections seems to be confusing to me. In some case replies to a reply are counted in other case not. The numbers don't really matter but knowing if someone left a reply to somthing would be nice. But with neither the counter nor the position in the list changing it is next to impossible to find out. On a side note as I already asked many times: Can we ever expect to see an option to sort replies by the time and date they were made? Might be just me but scrolling through a big topic after getting an email that someone replies often results in nothing at all. I see replies from several years ago on the top then some that are a few months old followed by newer or older ones. There is no order of any kind that I can see! So please, if any of the great code monkey reads this: Can you explain the logic behind the missing order? Can you explain why exactly it seems to impossible to sort replies in a way that makes reading and understanding what was replied possible? Can we expect to see a fix or selection buttons for the order in the new year?

Making a better spot welder....

I am in the process of building a proper spot welder from scratch. Proper more in terms of the electrical and electronics part but not so much in looks ;) My problem now is to find useful info on what power levels are required for certain tasks. I realise that welding thin sheet metal won't need as much time and amps as welding a 3mm stainless steel rod - but what is a "good" power level? I watched a bunch of Youtube videos showing various approaches but for many it seems the producer had no clue about the difference between creating a short with burn marks and a weld... Especially when it comes to creating battery packs with a capacitor bank as the main power provider you can clearly see the device burns holes but does not really create a welded spot. On the other hand there are a few videos showing spot welder made from a MOT that seem to produce a proper melted and welded connection. When I used a proper spot welder at work it had timing settings, power levels and even a feature to adjust how the current rises.... Not to mention a gauge that checks the pressure and only activates the welder once the set point is reached... There is a ton of info out there that after a thausand words still tells you nothing you need to know :( So is there anyone here who can shed some light on the actual process of spot welding in easy words for everyone to follow? I am aiming for a max output of around 400A @ 1.5 -2.5V with an adjustable shunt in the transformer core to avoid oversaturating the core. In a later stage I will add power control over the primary side but until then it is only time control, from a few ms to a max of 5sec if the damn controller arrives one day. Big questions: 1. Is a power control really required or is it possible to cater from thin to thick just by using different timing settings? 2. Since a MOT is used for the power supply: Is it better to leave the shunts out to fully avoid saturation by adding an inductor in line with the primary or is it still better to adjust the shunts under load to get the maximum power possible? 3. Aluminium and other materials benefit from using AC but would be good to have a DC output too, if so then what materials really need DC? 4. All I could find is that copper is used for the electrodes, due to resistance and heat transfer - are there other options apart from using copper? 5. Tricky one: I would prefer to use the secondary winding as the new primary to avoid core saturation and to lower the load on the power outlet. Where can I find very thin copper bar material that I can coil up and insulate as I would quite a few more turns to get at least 1.5V out of it? Just don't like the idea of spending days rolling a copper bar thin enough.... For the advanced model at a much later stage: Of course I would like to be able to use a proper power control instead of a motor dimmer or similar. For obvious reasons an inverter microwave jumps to mind. But after checking one I noticed one big problem: there are not really that many windings on the primary of the transformer at all! Same way our modern switchmode power supplies only use a few turns these things do exactly the same. After some quick and dirty initial tests I realised that even a single turn of thick wire already results in over 20V on the secondary. Wasted a lot of wire and time making one coil with 5 turns less and one with 10 turns less but the system would not even start with it. Seems these things need a fixed inductivity on the primary that matches the frequency used, in my case 36kHz. Would love to overcome this problem so I can at least go down to a single turn to get under 5V on the output side as space is non existing on these inverters. Can I cheat? Do I need to change the circuit to match the new primary coil? Am I thinking in the wrong direction altogether here? And added bonus would be to be able to adjust the power from around 15% to 100%, so far the electronics don't allow anything below 45%. Is it possible to drive these inverters in resonance? (Ok, off topic as I would like to use this for a beefy HV supply) Last thoughts: I know people already used Arduinos and Raspberries with displays and all but so far I have not found anything that shows how to do it properly. Seems all that counts is to create connection one way or the other and to call it a spot weld even if it is just a burn hole from discharging a capacitor bank through a needle like electrode.... For obvious reasons I don't want to create just another spot welder that makes a professional pee himself laughing about it. IMHO nothing beats personal experience with something but I don't really like wasting my time by trying what other people alread did a long time ago. So if YOU already built a MOT based spot welder and used for more than a few spots I would love to hear from you! Let me know what type you used, what problems or shortcomings you noticed or where you feel it just does not work out the way you expected it. From simple things like always getting bad sparks or arcing, over how easy or hard it is to get consistand results to whatever really annoys you while using your homemade spot welder. I hope that your feedback here will help me to write an Instructable on building a spot welder that does what you expect it to do, not once or twice, but everytime you use it. Mechanics might vary the same way the electrode style does but the weld should always be a proper weld that won't tear apart ;)

Pet Travel Kennel Into Doghouse

Hello everyone!  Finally made an account after using this site for over 5yrs because I'm hoping to find some advice. I have a big, plastic, dog-sized travel kennel (airplane kind).  Since my pet isn't using it anymore, thought I'd convert it into an outside doghouse seeing as though it's practically complete already.  To prevent rain from getting inside, I need to cover up the side & back barred "windows".  My 1st impulse was to replace the metal bars with wood, but rain would just leak in through the top.  Any thoughts on attaching a makeshift roof?  I've added a picture of it to help (the metal door has been removed).

Powering car LEDs via USB

Hi guys, I've always wanted to make my car (my parents car :'c ) a little bit more fun, It's a 10/11 year old ford fiesta without Bluetooth/USB. Here's what I would like to do, just wondering if anybody can see any problems with this. I know very little about power or how electronics work. I want to be able to skip songs and answer calls without having to pick up my phone, for that I am going to buy this:;=1∣=AP087GSGD7Y0R Now this will use my cigarette lighter for power which is fine until I get to my next part.

Two-way hinges

My wife and I bought an 80s designed house that's not that well designed. We keep one of the litter boxes for our cats in the garage, which is accessed from the inside through the laundry room; and we want to install cat doors so our aging felines can pass through the doors easily to get to it, while keeping the draft from the garage out of the family room. The interior door (between family and laundry rooms) is a standard hollow core and the exterior door (between laundry and garage) is fire code rated solid wood door.  We tried a standard top-hinged door with the cats already, at our old apartment, and the cats didn't take to it, so we we're hoping to do french doors, since they know how to get through normal doors pretty well. But we're kinda stuck on our lack of knowledge about hinge designs; we need hinges that swing both ways. Has anyone out there successfully completed such a design/installation and would be willing to share pics and secrets?

Turn my Raspberry Pi 0W into a bluetooth HID gamepad

Hello there ! I've been trying to get through this for weeks... many projects are quite similar but I have never found one that answers my problem. As the title says, I want to turn my Raspeberry Pi 0 W into a bluetooth HID gamepad. I figured out that another way is possible. Indeed you can create your own bluetooth HID device with either the Adafruit BlueFruit Ez-Key or a the RN-42 module (or even the HC-05 with the RN-42 firmware). But I want neither of these solutions. I want to use my Raspberry Pi 0 W in a way that it will be recognized as a bluetooth gamepad. Creating the gamepad is fine, I used the GPIO of the Pi for the inputs. But once the gamepad is physically done, how to make my Pi appear as a gamepad ? I've seen that you can use hciconfig in the terminal of Raspbian in order to change the class of the Pi and set it as a gamepad but I must admit that I didn't understand everything. And it's important that it appears as a gamepad and not as a keyboard. In a nutshell, I would like to turn my old wired nes controller in a bluetooth one, and play on another Pi where Recalbox is installed. (That's why you must appear as a gamepad and not as a keyboard, because Recalbox only works with bluetooth gamepads). Thank you in advance if someone takes his time to help me with this because I can't take it anymore haha !

Need help with a wiring diagram for a on/off/on switch parallel/serial battery

Ok I'm not really electronic savvy but I can solder and follow a diagram. This is what I want to do: I have a toy four wheeler for my kids. Has one battery and a push button that makes it go. When you release the button it stops.  I want to add another battery and push button so when you push the original button the batteries run in parallel. The speed will run the same as with the one battery but twice the run time. (please correct me here if I'm wrong) When you push the the new added button at the same time as the original button it will switch to running the batteries in series so it will be faster running on twice the volts. So i'm figuring I need some sort of on/off/on 6 pin switch and a push button switch but not sure how to wire it exactly. Found this which gets me close but I want to add in the push button switch to make it work instead of the toggle switch. The original button is on the handle and you push it with your thumb. I will add the new switch on the other handle. Something like this;=item2a889e8c53:g:YoMAAOSwr9VZwoA7 Any thoughts on this would be awesome!

I recently had reason to read Phoenix, AZ's main newspaper, which had an article entitled “Rehabbing PreFab”, discussing a local project at Taliesin West architecture school. Students are exploring the PreFabricated homes, with Modern architecture styling. Definitely a new take on PreFab. Exciting work, particularly the shipping container mod-mods. Doing a quick search turns up the website busyboo which has many articles regarding contemporary exploration of highly artistic PreFab units.

Hello, I would like your help on an idea I have to make an external recoil pack so VR players with existing gun controllers can add recoil force to existing controllers that do not feature it. Recoil and haptic force feedback controllers are $500-3000 in cost. Can you help me out. I have not attempted this sort of DIY thing before. I just need some tips and what I need to buy in order to get his done. thank you. I have all the time in world and would love to know what parts I will need. So far I have found some good candidates. I should add that I want this pack to be powered by a wall adapter and cable. 12V I am thinking. Recoil and hard hitting rumble will need juice. I can find a way to affix the device. I just need to know what parts I need, and how to wire it all up. I know I need a switch that can be physically connected in way that a trigger pull will engage the motors. I know I need help. Please any help would be appreciated. I also would like to use "solenoids" or "Actuators" I just need to know from more experienced builders what would be better for an external universal type "pack". The idea is that the pack can add great force feedback to any gun with a physical trigger pull, or something of the nature

Jewelry tools for sale

My boss recently purchased all the tools from a jewelry shop that was going out of business and subsequently has a lot of tools that he is parting with. While these are primarily jewelry tools many of them are perfect for prop building. He has some nice workbenches, casting equipment, benchtop laser welder, a large polishing station, plating rectifier, rolling mills, benchtop lathe, flexshaft motors/handpieces, microscopes, engraving tools and all kinds of small hand tools. There's too much to list here- I have a complete listing of everything with photos and pricing. Some of this equipment is pretty big/heavy so local pickup would be preferred (Boulder, Colorado) but he said he'll ship equipment if need be. After downloading and viewing the list if there are any questions just message me and I'll try to answer them as best as possible or have my boss email you. Thanks!
