I guess this is the most appropriate board to have this thread.
Anyone into scanners?
Use to listen to Police a lot, but they went digital in my area about a month ago. Pretty sure they're encrypted, but thinking of getting a digital scanner anyway, since it's easier to use/program/organise/etc. Probably going to lay down $300 on one of these.
>>934039 I use a Baofeng UV-5R v2+ for scanning, NOAA weather alerts, and FM commercial radio. My old man's got a Radioshack Pro-528 receiver that I used to tinker with - that could pick up trunked frequencies and could pick up State Police comms.
It's my first time with LED's and I am a complete noob on electronics. I want to make a circuit, pic related. 12 rows of 3 leds. I have a 12 V battery pack and the leds are with forward voltage(V) min 3.2 and typ 3.4 and 20 mA.
What I can't figure out what resistors to use, because all the info I found on wiring leds was only with parallel or series and I am confused what to do if I have this mixed circuit where series of 3 are wired parallel.
>>934004 I have an air pump putting air through an air stone in a mason jar. This is helping with humidity and oxygen but not much. I also have a humidifier putting some amount of humid air into the chamber from a whole in the bottom. I'm not too familiar with humidifiers but this one seems to not be working too well. I bought it second hand for $4. I guess you get what you pay for.
does anyone know how to dynamic motion tracking or whatever its called in blender? im trying to do gif related, basically focus on a specific part of a video and make the scene move around it as if the camera was locked exactly in place against the object. literally the only tutorials i can find are for putting 3d objects into a video with motion tracking, which is not what i want.
Ok so I now I'm retarded and an autist, let's get that out the way. I was trying to replace some speakers in my car and when I unscrewed the bolts I also accidentally removed the wire in between them that allows the seats to go down when u push the release. At the time I didn't realise and now my back seats no longer come down. I need help if anyone can, I just don't know how to fix this.
No so the bolts part is sort of irrelevant, so the buttons you push to detach the back seats is obviously controlled by the wire. I accidentally detached the wire itself that allows the car seats to go down, and I can't reattach it because when I put the seats back up they are covering the wire And it's unaccesable. :(
Does it need to be 1300? Will 1200 do? I only ask because ply will be your cheapest option, but it comes in 1200 or 2400 length. If you can get away with 1200 then you can make two desks per one sheet of ply.
How stable do these tables nee dto be? Are they for display or working on?
>>933904 Lrn2logicalDeduction you idiot. Do you genuinely think he means 1300 meters by 800 meters or something?
Recently acquired this Marantz PMD222 for cheap, it works pretty great except for one thing. Whenever it's playing and I move it, the tape speed slows down drastically. It seems to be proportionate to the speed at which I move it, but sometimes it doesn't happen. It happens probably 3/4 of the time if not more.
Naturally this is a fucking problem for a portable cassette tape player. I searched online, read the owners manual, browsed a couple of forums to no avail.
>>933884 Unlikely, dry joints would make it stop and start outright, not slow down, though in a unit this old it's not a bad check to make. Hanging a multimeter off the DC supply to the motor and observing voltage as the unit is nudged around will help confirm or deny this.
>>933883 Sounds like it has a bung bearing on its capstan pulley (pic related). If the unit slows when moved it could be because it is binding on something. Pulley is a big spinning mass of metal... Comment too long. Click here to view the full text.
What part in my elec furnace can I replace to make my unit more efficient, lower bills? Pic related Please read below..
You go us always seem to know everything about hvac/mechanical systems so I'm gonna run this by u. Long story short I own a 2 family building I lived up stairs while renovating bottom unit. Too unit had an existing hvac system about 6 years old total, when I bought the place. This unit does not seem that efficient stl winters would run me 300 dollars in elec bills, all elec. Now I live in bottom unit, I picked out the system, high efficiency,... Comment too long. Click here to view the full text.
Generally I would always recommend doing upgrades to piping. A thick wrap would help insulate the pipes that carry you heat and water to their destination. As far as mods to the unit... In not sure really.
the Power and Reset LEDs on my PC's motherboard (like in pic) flicker when i turn on the PC - and the PC does not boot. if the speakers are plugged into the 3.5mm jack they pulse ("wow-wow-wow..." sound) at at the same frequency as the LEDs flicker (~20Hz).
i checked the voltages on all the connectors from the power supply and they're all good.
does anyone have any thoughts on what can cause this flickering? dead caps something? i suspect that the MB is fucked, but how can i figure out what failed?
Trial and error, replace hardware until you pinpoint the damaged element. Try a different psu for starters. Unplugging everything you don't need. Sure it could be blown caps if your mobo is quite old. You'll know the bloated ones when you see them.
thx. forgot to mention that the MB is about 6 years old. all the caps look ok - no bulging or leaks. when i manually jump the "PS ON" and "GND" pins on the 24-pin PS connector, the PS turns on (and produces the correct voltages). but when i plug the 24-pin connector into the motherboard, the PS does not turn on. why is the motherboard not turning on the PS?
>>934041 Again with /diy/ always always always starting the troubleshooting process with bad caps/solder joints/traces/etc. Why do you always start troubleshooting with the most invasive and convoluted shit?
OP, try replacing the battery on the motherboard first, then report back.
Attach one rare earth magnet to one button battery and tape one LED light to all of that. Now you have a THROWIE, a little light that you can toss onto buildings, cars, etc, that will remain lit for weeks. Each one costs about 30 cents if you buy the materials in bulk.
Hey /diy/, mind helping me build some shelves for my desk setup?
Dad was never around to teach me woodworking, and I'm needing to build two shelves with drawers for under my PC desk. The dimensions are too niche to find in an average store, and figured building one would be a nice alternative.
Pic related, the spaces between the desk parts are about 11 inches wide and about 27 inches tall.
What kind of wood should I invest in? Nails or screws? How to properly line up the drawer railings? Any advice would be much appreciated. Thanks in advanced.
Well, my Ipod Classic simply does not turn on anymore. I already tried everything I've had read on google. Asked a tech support's guy and he told me something inside the Ipod must be disconnected. Anyway, I want to open it therefore I don't have any proper tool. Do you guys suggest anything?
