Soldering?

I got a new PC board from radio shack and I am going to be making a little flashlight.  I don't think the board is interconnected in any way, so is it ok for me just to use melted solder as a lead from one spot to another, like connecting the pos and neg of two led's.  If this isn't right, what is the proper way to use those PC boards.

how to make a tablet pc mother board to run android? or is there a generic board that can be bought?

I really want to make a tablet pc which is probably completely out of my depth but hey theres no harm in trying. obviously at home making a logic board for one would be very difficult and i wouldn't know where to start with the schematic. i was wondering if any companies do it or if there is a generic board that alot of the tablets use that i could buy. i dont see any problem with obtaining a screen and designing/ making a case. i obviously can't use a computer motherboard because of the size and heat of it. can anyone help? thanks in advance

PC half dead - not good

Machine will not POST - no beep, BIOS smart fan-control not engaging, PS2 keyboard has no power, monitor reads "no signal" Board does have power - things spin (like the CPU fan which shouldn't until it gets hot) Preceding clues(?) - I thought I'd developed tinnitus, but found it was the PSU (I think) making a high-pitched ringing noise, half the day unplugged and that seemed to go away. Display not engaging properly on start-up: If I waited until the machine got to Windows login and then switch the monitor on - no problem. Switching the monitor on before this point - black sort of standby mode. I think I might try the PSU first, then think about the mainboard. So far I've plugeed and re-plugged things, tried with 0,1 & 2 strips of RAM with no difference. Any suggestions welcome I spent a lot of time replacing 1 cap' in the PSU, then I replaced the PSU (logic being that if I've tampered with it an the thing still doesn't work I should replace it regardless) Then I bought a new board. I was a bloody-sod, CD/DVD still doesn't work... L

PC to Mobile Workstation Advice

I recently made a old antiquated PC I owned into a mobile work space/storage. Sadly I thought I wasn't living up to it potential, so I decided to ask the always helpful instructables community for help. I am looking for any idea that improves the look, functionality, storage, of efficiency of the workstation. (But mostly the first two) Box Current Specs. 1.5-12V power supply, cant be removed. See picture 1, its the box behind the two probes. Lots of space, Im not afraid to tear anything out of the box to make room for something better. Honestly Its pretty crappy at the moment with just some plastic board shelves holding supplies. I will take any ideas, I would love for this box to become a great instructables project. Pictures,  Picture 1 is current box, again not afraid to change it. Picture 2 is raw space, (minus shelving) keep in mind the power supply case could also rig sliding drawers.

Orange pi's 3.3V on board regulator

Hi everyone, I've set up a mediacenter with openelec on my orange pi PC. I've put a large heatsink on cup and rams and a small 5V 0.15Ah cooling fan. With two switches I am able to switch it on and off and choose between 5V or 3.3V alimentations from the GPIO. The 3.3v is intended to spin that fan not at full speed to reduce noise while watching film or listening to music with the mediacenter. I left the PC all the night open downloading torrent, and the morning later the fan wasn't spinning anymore. I powered off the system and used a day later. The fan were at that moment working. So my question are: Is it better to put an external voltage regulator (lm317)? Anyone can explain what happened? As I recently discovered that with zener diodes we are able to clamp the voltage to a specific value (if putted in the "opposite" direction, I guess), I was thinking if it were possible to use one of them in this case.

Electroplating for electronics

An idea has occurred to me about how PC boards are currently made. The normal process now is a destructive one, where unwanted copper is etched away. What about figuring a way to electroplate the traces onto a substrate? Various toys and model parts are made of plastic, and yet have been electroplated with a cheap form of chrome. Why not apply that to PC  boards? I'm thinking that a photographically negative mask could be used in a photo-sensitive process to apply the conductive surface to a heat resistant substrate, and then the copper traces could be electroplated on. Anyone have any thoughts on this, primarily at a hobbyist level? **note - cross posted in burning questions.

Can the CP2101 USB to serial IC be used to connect a microP directly to a PC without an RS232 port and a MAX232 IC?

Sparkfun makes an excellent breakout board for Silicon Laboratories' CP2101 IC. It looks like this board could be used to connect a PC to your microprocessor through a USB port without having to use a MAX232 IC to convert the TTL voltage levels to the serial port voltage levels and then a USB to serial converter. Drivers are available so the PC sees the CP2101 as a COM port so hyper-terminal could be used to communicate with the microP. The 'S' in USB stands for serial, it should would be nice to connect a PC to a microP using only one piece of hardware. Am I right about the CP2101 providing this ability?

Bios speaker randomly beeping? Answered

I finished building my computer a while ago, but initially removed the BIOS speaker as it kept beeping. Not a full alarm like if it were overheating, just a pathetic little "bip" every 10 minutes or so. The speaker is connected properly and it is the one that came with the board, and it makes a proper beep when I turn the computer on. I have disabled the CPU fan warning as I had it connected to my fan controller instead, and I also have thermal sensors on everything and everything runs nice and cool, so I honestly can't figure out what the problem is. I thought it may have been my dying hard drive, but I have replaced it now with a brand new hitachi 500gb sata-II drive that runs smoothly and I still get the problem (it just went off again whilst tying this). Any idea on what could be causing this problem and how to fix it (without removing the speaker). I have also tried it on Ubuntu and Windows, and I get the same problem, not that it should matter.

How to know if Arduino is working?

I bought the RAMPS and Arduino Mega 2560 and 5 stepper drivers. I plugged in everything to the pc and everything was working perfectly. I installed all my arduino drivers easily. Then at my friends place when I plugged the psu to the mains and turned everything on, 1 of the stepper drivers started smoking from the chip attached to it and got fried. I think it was  due to too much voltage. After a while removing the burnt driver when I connected my Arduino to the pc, the pc does not find its hardware. Only this 1 light stays on and nothing happens. I don't see that there is any physical damage to the board.. but there might be .. I am not sure what to do now.. I want to know if I can check wether the board is still working and how can I connect it to the pc?

Make a hard drive constantly spin outside a PC case?

 I'm currently working on a POV hard drive clock. Instead of designing and building a separate circuit to drive the motor in the hard drive, I thought I'd just power the circuit board of the hard drive and let that spin the motor itself. I gave it gnd, 5v and 12v and it spun up, fast and stable too. ~30 seconds later, it stopped spinning and the only way to make it spin again was to turn the power off and turn it on again. Obviously this isn't good for a hard drive clock as it needs to be spinning constantly So how can I make the hard drive spin constantly? Can I pulse a request line on the IDE cable every once in a while or do I need to actually transfer data to and from the hard drive? If it isn't too complicated I could program a PIC chip to talk to the hard drive to keep it spinning but I'm not sure about the structure of the data or how to talk to the hard drive. Anyone know the simplest way to keep it spinning? Thanks, Louis.

Disk boot error? Answered

Last night, I wanted some files off my laptop drive, so I stuck it in an external enclosure and plugged it into my desktop (whilst on). I then turned off the desktop without unplugging my laptop drive and turned it on again today, forgetting to unplug it. I have USB booting enabled, so it tried to boot from the laptop drive and as I was out of the room when it was booting, it entered the recovery partition as the hardware is incompatible. I have done this before, so I just turned off my computer, unplugged the drive, and restarted. Instead of booting from my primary internal drive, it got stuck on the post screen. It detected it, but wouldn't go any further. I then thought that it was still looking for the USB drive, so changed the boot order and removed usb boot, same problem. Removing my primary drive just returned the error "disk boot error, insert boot drive and press enter to continue", so I inserted the primary hard drive (I have it in a hot-swap bay, so it can easily be removed, although being my primary hard drive, not "hot"). After doing so, it kept returning a similar error. I then figured that it was still looking for my laptop drive as a primary boot device, so I cleared CMOS with the jumper and after setting it up again, disabling every other bootable interface except the sata port my primary drive is connected to, and it still just gets stuck on post. I have left it about 10 mins and still get the same problem. It is also hard to enter BIOS or any of the other utilities, as it waits until after post, so I have to either remove all drives or insert the laptop drive in it's enclosure. How can I get my desktop to boot from the primary hard drive again? Inserting the install disk is also hard, because I don't actually have a DVD drive yet, so I installed Windows 7 extended trial through a memory stick from my laptop with a disk drive. I have since deleted it off my memory stick, and my laptop is now in pieces hooked up to my monitor/keyboard/mouse instead of my desktop. It is on it's back and the hard drive bay is open in case I need it again. My BIOS is award with additional features on a Gigabyte GA-H55M-USB3 board. Both drives are Hitachi sata-II drives, one being 3.5" and one being 2.5".

using Smart TV board from dead TV to make standalone player

Hi everybody, recently I hired a new ISP company (italy) with a SO AWESOME VOD TV service, like netflix and also live tv, , the app works very great and with a good quality, the problem it's only available for LG and SAMSUNG smartTV, no way to watch it on PC; mobile, chromcast.... So... i have 2 more Sony TV and a 4k Projector and i don't find a dam solution to watch this app on rather than buy another 2 LG/SAM tvs and throw the projector (which is not an option hehe) So I wonder if I  can just buy a broken LG/SAM TV (even a new one) and use the smart TV board as player, I think, it's pretty easy to just unattach the board and put a power supply, but i wonder what kind of video interface this board uses, I will need any kind of magical WHATEVER to HDMI converter, and also it need to have audio aswell  I read most of the TV use proprietary interface / connector to send image to the panel, the app it's compatible with more than 200 models from LG and Samsung, maybe you guys know the exact model i shloud find to "hack" the board in most easy way Thanks!
