Portable Homemade TV Answered

I built a TV from an old laptop screen and one of those LCD control boards you can get from eBay but I’m curious how to go about adding a battery to it to make it portable. So, my question is, how do I go about battery safety and how do I control charging and isolation? For example, if I plug the TV in because the battery is dead, do I just have a charging board between the input and battery and let the charging board take care of the rest? And the same question is applied to when the battery is at peak charge but I don’t want to use the battery just simply plugged in. The battery is a 12v 2A lipo and I don’t want any fires. I’ve thought about adding a switch to simplify things but that’s inconvenient and armature I could make a circuit that would cut off the flow when the battery is at peak I suppose but I’m not sure of the schematics or if that is the right approach. I’m good at building just not figuring this stuff out….

homemade signal booster? Answered

I was trying to figure out how to boast my signal coverage in my area, and a got an idea: to use a UHF amplifier, to pick up the towers signal and rebroadcast it. of coarse since things like WiFi, Bluetooth, and cellular 2G/3G/4G networks use two way radio, the signal can go back to the reviving end of the UHF amp, and get broadcasting to hit whatever tower. my phone should better recognize the tower, as if i just magically made a tower 2 feet away. however this might also amplify stay noise. if this idea doesn't work, why not? i think i am going to need at least a 20dB increase in power, but as of now i  need to do more research. but if i can buy a product that does a similar thing for less than $40, i would. http://en.wikipedia.org/wiki/Dead_zone_(cell_phone)#Dead_zones  http://en.wikipedia.org/wiki/Repeater http://en.wikipedia.org/wiki/Wireless_spectrum (cellphones use UHF spectrum) http://en.wikipedia.org/wiki/Signal_booster

Homemade MINI Particle Accelerator? Answered

Hello!  I'm working on a homemade mini particle accelerator from stuff in like hardware stores and thrift stores. I was wondering if someone could give me a definition of a particle accelerator and their hazzards? Also the only thing that I would need to buy off eBay is a some sort of detector for electrons. Heres a list of supplies: concrete, CRT Monitor, wood, lots of thin copper wire (for the electromagnets), a electron detector, and a power supply. It would be a circular accelerator too. Any ideas or info is welcome! PM me or just comment below!

Homemade Car IR Night Vision ?

I am a retired guy with less than perfect night vision. I have installed a LED Backup camera and portable display in my Camry and wonder how hard it would be to do the same only looking foreward. Ebay has a lot of IR cameras that include IR Light LEDs. Shouldn't I be able to connect one to my monitor to get some extra driving safety? Of course, everything is possible to the guy who doesn't know how to do it! Thanks in advance.. Here is an article from a BMW site I think............. "...In 2000, General Motors offered a thermal night-vision system in its Cadillac line of vehicles. The system was innovative, but it was also expensive and didn't produce very clear images. Toyota also gave night vision a shot, and even now the automaker continues to offer an in-dash system in some Lexus models. The Lexus system has its fans, but if it's so effective, then why hasn't this technology spread to every vehicle on the road? One theory is that it seems as if the technology just isn't fully ready for automotive applications. Not yet, anyway. As you can imagine, night-vision technology is expensive and if you use inexpensive components, the quality simply won't be there.  Two of Germany's automotive stalwarts, BMW and Mercedes-Benz, have taken a damn-the-torpedoes approach to in-dash night-vision systems. These two auto manufacturers have been offering night-vision systems in vehicles since 2006..."

Maxablaster: The homemade 52 million candlepower flashlight.

A homemade 52 million candlepower flashlight. So that's what engineers get up to in their spare time.The article says 38, but apparently Ralf has already upgraded to 52 with his newer setup.The 45-year-old Dutch optics engineer has been building his own lights since he was eight, but his recent 38-million-candlepower creation, the Maxablaster, is more like a miniature star. To start, Ottow stripped out the innards of a powerful commercial flashlight and switched in a mercury arc bulb, which generates light by creating an ultra-hot plasma between two closely spaced electrodes inside the gas-filled central chamber of the lamp. That results in a brighter, more focused beam but also kicks out more ultraviolet light (hence the sunburn, a product of early testing). So he added a specially coated reflector and designed, ground, and coated a new glass window that would trap UV rays while still pumping out light.Powered by a pack of 54 batteries, the Maxablaster can put a bright spot of light on a cloud four miles high and illuminate a house from just as far. But Ottow doesn't use it to spook his neighbors. It's not a torch you'd walk your dog with," he says. "It would probably cook your dog." link

Amp for a homemade speaker box with car speakers?

The speakers are almost definitely going to be a pair Sony Xplod XS-R5743's Specs: 4-Ohm 190W Peak 35W RMS So with these power specs, what should the power ratings for the amp be? I considered building an amp, and unless there is something I've missed, it looks cheaper just to buy a car amp and just make it run from a wall outlet after a transformer. Especially when every amp that I see being built is a low power 1W LM386. Please, let me know the best method for amplifying the audio to these speakers and the required power. Thanks

Custom C Compiler for homemade instruction set? Answered

I'm designing a relay based computer.  It will be an 8-bit cpu made entirely out of relays, except for the RAM and program memory. I need an instruction set, but I am not crazy enough to try and make it run the x86 instruction set or anything like that, so I am making my own.  It is a fairly basic set, only 60 instructions, with a quarter of them being data movement. I tried compiling some basic computation programs, like a 16-bit add and an 8-bit multiply program. It is a pain trying to compile it so I was wondering if there is a way to plug my instruction set into a compiler, such as gnu's gcc.  I don't even need it to create a machine code file, I just need the assembly. Is something like this possible??? and how hard would it be to implement???
