Long story short, the lil rubber thing in my 360 controller that springs the "A" button back up when pushed is getting stuck and won't spring back up like the others. I was playing KH2 on my pc and I guess the button mashing was too much for it to handle. Any way to fix this? Any ideas as to how I can get the reinforce the rubber to make it firm again?

Sorry if this is too vague or has already been answered, but I have an idea and I need to patent it. How do I go about that and how do I make sure it's not already patented?

Beekeeping y'all!

Beekeeping y'all! 3 posts and 0 image replies omitted. Click to view.
I have an opportunity to take up Beekeeping as a hobby (Or even profession). Do any of you guys have any experience with this? Essentially, I'd like to get a few deeps full of bees, with honey and wax production so that I can sell it to local beekeeping clubs. I've also taken a fancy to the idea of making mead and selling it, provided things go as well as I plan.

Help, Dad is driving me off piste!

Help, Dad is driving me off... 12 posts and 0 image replies omitted. Click to view.
/adv/ advised me to try here. So who knows how to fix a pair of skis. Dad got a very nice pair of skis, then after a year or two he hit rocky patch that scratched them up. So he garbed some epoxy from mom's jewelry making kit and filled it in. But the P-tex wax would not stick to it so some spots had different amounts of friction, which he claimed ruined everything. Now over the years I have been dragged into skiing and Dad has become even more obsessed with it as I only kind of enjoy it. Now He has given me these old skies so I don't have to use the rentals anymore. However he took it upon himself to fix his fix, which likely wouldn't have bother me given the rental quality I normally used. But somebody told him mixing graphite powder in the epoxy would fix it and he wants the best for me. So he has started reopening the scratches. Now I took a few classes on material engineering so I know a thing or two and this idea of graphite powder additive sounds wrong in so many ways. It sounds a lot like a misread recipe for Electra, a P-tex with about 15% graphite powder to help modify it for extreme racing conditions. But unfortunately I don't have time to properly figure this out, because Dad didn't ask the one person in the family who knows there is more then one type of epoxy, and as you can guess he is a bit stubborn on this. What would be the best fix to use to have them ready by Saturday? I have tried to get him to just reapply the epoxy, not the best idea I know but it should work well enough, but he wants them to be better so it won't mess with my skiing performance. To him getting down the hill and have fun is not good enough, one needs to perform perfectly. Any fix for the skis? I'll deal with the ski obsessed Dad issue another time.

How much would it hurt the thermal efficiency of a cluster of 5W LEDs if instead of MCPCB they were soldered to a thin standard PCB. In both scenarios lets say there is a CPU heatsink stuck to the bottom of the board.

Hi /diy/, I have an unlimited source of these glass things, they come from non refillable insulin pens, they are divided in two types, to the left the wider tube (9,5mm) but with a narrow top (3mm) and to the right a more narrow tube (9mm) a bit longer (both are around 63mm) and with a top hole a bit bigger than 3mm. Both are fragile and have perfectly smooth inner walls, I also saved the rubber plungers. What can I do with them? >inb4 throw them away. Btw I already tried a tilt switch.

Someone build this invention: A backpack slung leaf blower with an attached alternator powering heating elements inside the shortened tube that are attached to heat sinks that also increase turbulence that widens the stream of air. The heating elements would be the variety that transfer heat and become cold at the mounting point to prevent them from melting the plastic tube. You can have the copyright.

How can I turn a web cam into security camera? I was thinking about a motion activated system that I could hide at the entrance of my house. I don't want to use it with my computer though, as it's a high-end system (850W PSU) and I'm away for several days at a time. Any ideas? Something like an Arduino system would be perfect, but I've read that they are not fast enough for video processing. Pic related, it's the Logitech C270 that I'd like to use.

CrossBow

CrossBow 25 posts and 8 image replies omitted. Click to view.
Hi diy, I would like some input on making a crossbow, what would be a good, cheap material for the bow part? and the actual cord? I already have a frame, also trigger/cocking mechanism thoughts would be graciously accepted. My general plan is to have the frame ( it's one of those steel bars they use for the cheaper stop signs) and have some sort of smaller coaster inside that to hold the bolt and push it forward, this coaster will probably also be used a s a cocking body, for the box I was thinking PVC, and the chord would be parachord pic is just a project I did before

I need help deciding between pursuing a trade. I've narrowed it down to either HVAC or electrician. The downside to electrician is that even after getting an AAS from a vocational college, I'd still have to work for 4+ years to be considered an actual electrician, whereas HVAC technicians can jump into a $25/hr job straight after getting certifications. What are your thoughts?

DIY noon here and I was wondering if you all could help me with a broken doorknob. I live (rent) an apartment and the landlords aren't exactly swift to fix things (the hallway doorknob is simply not there and has been that way for 3 months) so I tend to fix minor stuff on my own if possible. My outside access (legal fire escape) door is old as shit and leads out onto a small metal balcony (college housing, small a pts in rural areas) anyways I have to strong arm the door when I want to open it and have been putting 3 in 1 oil on the hinges when I do so about once a week to make sure it's accessible. With the cold and my tugging I managed to completely break the knob off. So I figured I'd replace the knob with one from my bedroom for now, but several things went wrong 1. The knobs are different types 2. Once I got both ends of the knobs off, I realized the rest of the hardware is built into the door (the part that clicks into the hole on the jamb 3. The outside part of the doorknob fell down and disappeared into another universe 4. The knob hardware from my bedroom knob can't fit in the square slot on the hardware built into the door So thankfully there's a large inside bolt lock but I stuffed a washcloth in the knob hole for now. The problem is the plastic ring inside the rectangular hardware in the door is too narrow in diameter. Could I maybe shave the plastic off a bit and then put the knob in without breaking anything? Otherwise what else can I do to fix this? I was going to combine the good half of the knob with the one half of my bedroom knob but it just completely freaking disappeared and there's five feet of snow on everything. I hope you like how I tried to appear DIY core by saying 'hardware' instead of 'the metal thingy' a lot.

I've got an outside light like pic related but less shitty looking. In the past few years I've gone through a few of these because the sensor which determines when to turn the light on and off based on the level of light outside goes bad. I believe this one went bad from the cold weather one night. So, why do these sensors go bad from the cold, and what can I replace the sensor with other than a switch? I don't want to run any wire for a switch because it's mounted high up on the outside of a garage. Would also like it to kick on and off by itself when it becomes night and day. Any sensors that will withstand the cold nights that I can put in here and they will work?

Boss where I work is wondering about using a electronic inventory system to get rid of the paper one. I work at a small shop that deals with basic tools that are given to workers that go out to job sites. Can I just build a small system that scans bar codes using a usb scanner that saves it to a simple text file when tools are scanned in and out?

Hey /diy/, I come to you again, looking for guidance and solutions to two basic problems. I volunteer for a local group that does bake sales to raise money for our charity. We require two displays for cupcakes, and other baked goods. Both designs we came up with are generic as fuck and have already been done before. However we can't afford the commercial versions that are sturdy enough or the right size. I've attached the first design, and will be attaching the second below. Anyone have any ideas on how to build these? We require them to be able to fold or collapse down to very small height for transportation and storage, but be sturdy when in place. Budget for each should be within 100$ USD. Size for the three tier plates should be about two foot long for the base plate, and square. Next one should be 1 1/2 ft, and finally 1 foot. Same goes for the shelf display for sizing, and they should both fit on a standard size folding table. Thanks in advance gents.
