Usb male - male cable to connect 2 computer without a 'bride'
Although my flyback transformer driver appears to work very well up to 18V operation, the arc length is not satisfactory. I increased the voltage to 25V which allows 2 to 3 inch stable / hot arcs. However my 250V 18A rated MOSFETs appear to fail periodically esp. When adjusting the potentiometers (for adjustments to drive frequency and duty cycle) I Tried sticking a 1N4007 reverse biased diode across but I don't think it changed anything. I still see >300v positive voltage transients. I also tried using a neon lamp without a ballast resistor, but it did not appear to change the waveform, and glows way too brightly. I tried using 3 (really old but giant) 30V zener diodes in series but they latched up, failed, and went up in smoke lol! So clearly these HV transients have a lot of "oomph" behind them. D: I am reading an article on maxim electronics page about snubbers https://www.maximintegrated.com/en/app-notes/index.mvp/id/848 and I'll experament with some of the circuits presented there but I can't really calculate values needed for the components because I have not characterized my transformer with custom windings and a loose ferrite core. Those things will be subject to change anyways since I do not plan on supplying a specific flyback transformer with this kit. So I want something that is more universally going to work. This high voltage is just PITA to deal with. How can I reduce it to 200v without hurting performance?

My TV has a USB port for plugging in a thumb drive to play videos and music. As do several other devices Im aware of. What I would like is a device that when plugged into my TV or such will pretend to be nothing more than a thumbdrive but actually be a wireless adapter that connects to my network and the 1TB network storage so I can access all my files at once.

Hackerspaces have gotten pretty popular among makers across the world. They are a great place to borrow tools and share knowledge. But what about people that don't have local hackerspaces? The solution: social network. Digital hackerspaces! Great for people that don't have physical buildings, or can't afford to round one up. If you think about it, that's what instructables is! The idea is to have video chat and forums to share knowledge for projects. If you guys would voice your ideas, that would be great!

I tried to use the Instructables app to write an instructable. I loved it, writing an instructable as you go and clicking the camera button was great, made it really easy. BUT when I got done and went to publish it I clicked publish and it said it was uploading photos. I laid my phone down, Moto G running kitkat 4.4.2 on the counter, when I came back it said network error unable to upload. So I clicked done and tried to upload again, this time it immediately said network error couldn't upload. So I completely closed the app tried again, same. Restarted Phone, same. All the while having a strong WIFI signal. So as last resort, I cleared app cache, well, this deleted my instructable........ Those should really be stored in a separate file that is not erased by a cache clear. So what was wrong? I had a great internet signal, there was NO network problems. Webpages and instructables in the app loaded fast.

Hello there, I am a network administrator and trying to create a simple device to test the alarms on our systems. Since I am not an electrician of any sort, I have an idea of what I need, but no idea of parts or names to order. Basically, I need to have a basic on/off switch with button that I can wire to a CAT5 cable. Simple enough, stops traffic at the push of a button but thats the obvious part. I also need to have some control over how long my connection times out, and after some research, I think a timer relay does that, but I can't be sure. It just needs to turn the activity back on after it goes off say between 1 second and 10 seconds off, the connection turns back on. If I can accomplish that, than I would also like to add a dimmer type device such as that of a light switch dimmer, but smaller and working with less voltage. So... Can this be done with all 3 electric devices? The closest thing I found in searching was some generic Lag Switch, but it did give me a starting idea of how to design it. I drew a simple draft of what I had in mind. Any help by some electric gooroo's would be most appreciated. Thanks! Jonathan

There is a water tank on top of this villa (about 40m up.) On the ground floor is the pump. I wanted to put a fluid level indicator in the tank that can be hooked up to a PCB. The board will then be hooked up to our internal network. At the pump will be a relay to turn it on and off, also on the network. This way the pump will turn on and off automatically.Ideally, the whole system would be web enabled and allow for logging, but that more of a "wish list" then a requirement. could I do something like this with an arduino board? I don't have much experience with them, but I'd love to learn more about them.

I seem to be fighting a loosing battle with my network, things just never work like they're supposed to.For example, sometimes I have to reinstall my network printer on both my laptop and my ibook to get it to print again, even when the server has been running fine sans problems for a week, it will randomly do this shit.Another example is, right now I "was" just trying to copy some music over to an external firewire drive on my server that I have shared. I had the permissions on everyone set to full access yesturday but I noticed when I restarted my server, it did not detect my drive properly until I re-seated the firewire cable :S Thusly somehow it lost my share configuration for my music folder.I set it up, but this time I left it on read only because I wasn't planning on adding any music earlier, itunes and everything was working fine when i mounted the volume. I went on there and changed the permissions back to full access just 20 minutes ago as I wanted to add some music to my drive, I right clicked in my mac os x explorer and made a new folder just to see if I could copy over now, it worked, aswell as deleting the folder.So I drag the 60mb folder of mp3 files over, and it just sat there...and sat...and sat.... until eventually giving me an error -36, upon searching about, it means "-36 ioErr I/O error (bummers)".That's straight from the horse's mouth, and that really tells me nothing, what exactly does "bummers" mean???It's frustrating for me non stop, and it does this to me with other shares in mac os x, or they will randomly disconnect for no reason, sometimes after 15 minutes or sometimes after 3 days. I will note too, I can't connect to my server now, it just says missing alias in the mac os finder. Yet I can VNC into it no problem, wowa, but just upon checking my pc just now, it can't access any shares on it either, the cursour is just spinning, however I usually have no problems with my pc's accessing it, other than the printer thing.I'm just so god damned frustrated with my set up, I've looked it up and down until I was exhausted, several times, and I know I must be missing somewhere along the way, but I just can't understand how it doesn't work like I want it to. Shares are set up, firewire is out of the question, permissions set up, mac os x can log into server, check. It's all good until I actually go to use it for something when I really need it.I'll have to restart my server now to get it to work properly again...it was fine until I vnc'd into it to change the permissions, im gonna try restarting it now and just access it from it's own screen, perhaps vnc has something to do with it.Oh and to clear up any questions before they're asked, this is how I have it configured, as quickly and detailed as I can explain it:My network starts at my ADSL +2 4 port router/modem thingy (Speedtouch 546, it has it's own connection issues on the isp's side, but they don't seem impact LAN side data flow)That then gets split off to:*Port 1: iBook G4*Port 2: 25 ft. cable to 8 port switch (I'll explain that a little further down)*Port 3: 50 ft. cable to apple airport basestation in livingroom for wifi*Port 4: My main AMD PcMy ibook is configured for DHCP with manual address 192.168.1.64The switch just makes the modem think I have like 5 computers hooked into one port lol...My airport, for a long time I thought was perfectly fine as far as usuage with my thinkpad, however, I've been noticing the last few times it's powered on, the airport connects to the thinkpad, but assigns it a 169.xxx.xxx.xx address which does not exist on my network, but if I turn the wifi off and back on, it connects fine and assigns it a dynamic ip on my 192.168.1.xxx network.Other than that, I have it in bridge mode so that it acts pretty much the same as if the laptop were wired via ethernet, vnc, filetransfers, and online games all work good albeit the wireless delay, still not bad in VNC however.My AMD machine is set up for static ip at 192.168.1.66Switch:Port 2 of my modem goes to port 8 (uplink) of my switch.*Port 1: My server (Configured for static ip at 192.168.1.65)The rest are just my B&W; g3 setup for static ip at 192.168.1.68 and an old P2 I believe is at .69 and a 1.5 amd athlon aswell setup on 192.168.1.71, all of those in no particular order except I made sure my server stays on port 1.I did have everything setup so my server was on port 2 of my modem all by itself, but I needed the switch over by my server so I moved it, however, I was still having these problems before hand, even when my server was running on a completely different motherboard!Also, maybe could someone tell me why my server won't boot unless I have a bootable disk in the drive (IE: my windows 2003 server install disk), just so it goes to "press any key to boot cd.......", of course I don't push any key, and it continues to boot into windows.However, if I dare start my server without that disc in there, it simply goes to "Invalid System Disk error, insert correct/valid disk (can't remember it word for word), and push enter"I've tried reinstalling windows server 03, and same deal, yet it's using the same hard disk for the OS that my previous motherboard used and booted from not a problem.I really apologize for the long post... but I've quite literally burnt myself out and lost all motivation with continuing to expand my computer network and so I figured I would ask for help on here for one last resort, but I know many people probably won't read it due to the long post, but I have a lot of problems I don't have answers for and I need to explain myself somewhat thoroughly or else I won't find the proper solution for the problem, now will I?

Needless to say I made it to the kitchen without any mishaps and brought everything into the dining room. As I was eating breakfast, I was staring out the window at my bird feeder, with the news going, when the idea hit me. I'd seen other instructibles on digital picture frames which use computers and essentially integrate them in the house in a unobtrusive manner. Why should I have to walk around with my laptop when, theoretically, I could have a network of computer stepping stones integrated throughout my house. Is it possible to program a thin network where all the clients mirror one laptop? Is is also possible to use Johnny Lee's infrared fingers to turn on/ control a digital picture frame thin client in places where you don't want to use a touch screen? ie. the kitchen, workshop, or even in a hospital?... Could all this be done economically by re-purposing used school/uni computers, and freeware like Linux and Ubuntu and Cloud One?

I have a wireless printer on my network which has been a godsend to me, but it requires the network to be unsecured (theoretically it can log into a secure network, but that just never works). I was fine with that at my old house, as my neighborhood's average age was about 60+, with my wife and I bringing that average down from 75+ due to being the only 30 somethings in the area. But we just moved, and I'm seeing already a half dozen leeches on my wireless, and about 6 dozen nearby strong signals all secured. So I can't secure my signal for the printer, but don't want to share... what am I to do? Another issue is added to the problem - the reason I moved to this house was the neighbor across the street from me is a long time friend, and we thought it would be a good idea to wirelessly network for lan games, as well as splitting the cost of a high speed line. But my signal dies somewhere in the middle of the street, and so does his! So now, I want to boost my signal to get it over to his house, strong enough to let him play games and download files without noticing any delays, PLUS keep it 'unsecured' so my printer can get into it, but still block out the rest of the neighborhood who is leeching off of my signal. Is there a solution possible?

At first, I thought it was a cartoony parody of starwars (perhaps a joke in that Panda movie, all I saw was Yoda). This could not be serious, the animation looked like something straight out of the Incredibles. After some investigation I discovered it was totally cereal. It is a trailer for a 90 minute long preview of a cartoon network series. Who would pay to go to the movies to watch a 90 minute preview?! This is the description of the youtube video:The 90-minute premiere episode of the CGI animated series Star Wars: The Clone Wars will have a limited release in U.S. cinemas starting August 15th.Not only will this be the first 3-D animated movie for the highly-successful saga, but this will also be the first Star Wars movie not released through Twentieth Century Fox. Fox released all six Star Wars movies, plus the original microseries The Clone Wars on home video.But Warner Bros. and Turner Broadcasting will release Star Wars: The Clone Wars this time. The principle reason is that Turner's and W.B.'s subsidiary, The Cartoon Network, managed to snag the rights to the series from creator George Lucas.Star Wars: The Clone Wars on The Cartoon NetworkThe new series will premiere this fall on The Cartoon Network, later airing on TNT."I felt there were a lot more Star Wars stories left to tell," said George Lucas in the press release for Star Wars: The Clone Wars.

"For 30 years, Star Wars has shown that it appeals to a huge breadth of fans. Star Wars: The Clone Wars on Cartoon Network will be appointment television for everyone in the family. We're thrilled to be working with Lucasfilm again and very excited to be playing a role in bringing this remarkable adventure to viewers."The Star Wars we all know and love has been reduced to a cheap cartoon, made with the sole purpose of trying to squeeze as much money out of the name as possible.

So I did a google search and it seems others have also been interested in such a thing - albeit the most recent queries being at least a year old. The answers were - "I already have that on Vonage" - sorry - don't want voip!! And various programs that would let your computer, with voice modem, do that including linux programs. Well - I don't have a full blown computer on all the time and am not likely to. And so I thought - how about a small computer - but don't have one - couldn't think of one ... And then I thought .....
