So I'm a first year EE student and I have to build a version of the arcade game whack-a-mole with real whackable moles (so not just flickering LED's or something like that).
Now, I really like electronics but don't know anything about mechanical components to save my life (I have some know-how on simple (stepper) motors but that's about it). Yet I need to design a mechanism for moles to pop up that I can electronically control and I need a way for the moles to be pushed down again and to detect this. I guess I could accomplish the...

Found this site just now. Seems cool because I don't have a laser cutter or the money to buy one either. Has anyone tried the service? I'm a European so will that make ordering more difficult/costy? Any ideas what kind of cool shit to do? I'm a wizard with vector design programs but don't have any ideas.
I registered and didn't do anything so they started bombing me with automated e-mails and eventually offered my first design under $20 for free so that's pretty cool I guess.
Hey diy, the side of the ash tray broke in my suv. I tried supergluing it with no success. I'm thinking I have to step it up but Google failed me. I did find that jbweld makes plastic epoxy called plastiweld epoxy putty. Have any of you tried this or are there better things to use? I'm not concerned with it opening up again as I don't smoke.
>>945620 That's what I thought but I left it there for 3 days without moving it and as soon as I took the support away it fell off. Tried it again with better glue placement and the same thing happened.
Hey /diy I appreciate your advice and now I have one question. Pic related has a mini USB in. I have a couple of cables to rip off. My netbook needs a speaker asap and right now I cannot afford a shitty walmart $17 ones. So, how should I connect wires to make a cable connecting generic 3,5 outlet of netbook with mini USB inlet on MP3 player? I googled a bit and found some color schemes and layouts but still not sure. I will cut wires and post pics in comments
btw, if somebody knows how to hook up bluetooth usb adapter to lucid puppy linux and connect to wireless... Comment too long. Click here to view the full text.
>>946803 Your speaker thing is using a usb connector out of spec.
A fairly safe assumption is that it still uses the +5v and ground pins as normal so you could charge your box thing with any standard usb outlet.
The line in presumably runs on the data pins then. Ground is ground. Left/Right goes to data- and data+ respectively. Or reversely. There's no real way to tell without experimentation, and most sound cards will just let you flop the channels if you get it backwards on your connector.
>>946801 Easy as pie. Just take the audio cable for your pc, cut one end off of it, strip the ends of the wires so the copper is showing, solder them on to an analog to digital converter, then solder the ADC to an audio over USB digital module. Finally, connect the audio over USB module to a mini USB cable and you're done.
You'll probably need a 5v supply, some breadboard, the ADC chip, the audio over USB chip, some assorted caps and resistors, and possibly some jumper wire too.
>>946312 When I need a tool I hunt for them in yard sales and antique shops. I think the oldest thing I have a Universal #2 Food Chopper (Landers, Frary & Clark) and wood planer, both from the late 1800s and tons of stuff from 1900-1950.
I'm looking for a drone to make skating montages for YouTube, it has to have a decent/upgradable camera and I would prefer it had some sort of gps rout autopilot/follow mode. Budget: 1.500$ if possible I'd like to have 300-400 left for a new board.
How can i turn my Galaxy s4 without a battery? Is there any DIY to simulate a battery? when i short-circuit the first 2 pins of the 4 the battery connector has, it reaches the bootloader, but when i try to enter recovery, it reboots.... can anyone help me understand what do i have to do?
Hello /diy/ I have an old samsung S5260, perfectly working. I wanted to know if it was possible for me to transform it in a little wireless camera. I actually have a samsung galaxy a3. I do not know anything in coding etc And I didn't found anything to do such a thing Help me please
>>945317 For /diy/ projects or profesional? I personally use cheapest chinese ones for my diy-ing. Also found a supply for the angle gears so if they crap out for some reason i just replace them. For pro, makita or pro line of bosch (cheaper one are even worse than cheap chinese one...) Hilti makes great equipment also.
