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?

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've spent hours searching the internet, but not a found an answer yet. When I use the add a printer wizard, I followed the steps as shown in the pictures below. Everything is going great, until I see my network (MSHOME) with no printer underneath (last picture). The network printer does work for the 2 Mac computers in my house, but it won't even show up on the 2 Microsoft computers. I need to print from the Microsoft computer (and not the Mac) because Papakuru paper-craft files ( .pdo file) can only be opened on a Microsoft computer. I really need to print the paper-craft patterns so my little brother can make a paper-craft Daft Punk Halloween mask! My OP system is Microsoft XP, running on a Dell computer. The network printer is hooked up to a mac computer (if that matters) Please help!!!!

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.

Question by Robertclove
I am on the CCNA networking track at my local college, so a friend gave me a managed switch he was about to recycle so that I could play around with it and learn equipment that wasn't Cisco. He said that a few ports were bad, but other than that the switch was fine. When I power it on, the self-check light starts blinking, along with the red fault light. I assume that is because of the bad port(s). It does not output anything at all to putty... even during boot. I've tried pressing the clear button and the reset button, but nothing changes. The switch is a HP Procurve 2424M. Does anyone have a suggestion of something else I could try? Thanks!
Question by thegeekkid | last reply
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

I was hoping that SOMEONE made a telephone answering machine with a network connection so that it would do its thing like any other digital answering machine but the messages could be managed over my network. 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 ..... Raspberry PI!!?? So small and low power that it could even be put in an old answering machine case and low power draw. Does anyone think its enough computer to do this? Anyone up to inventing one?

I have a fairly extensive lan in my home that is constantly expanding. I want to do some custom wiring and started looking into building my own cat 6 cables. When I started shopping for the wire I noticed a lot of complaints about wiring not being capable of carrying gigabit speeds, CCA being sold as solid copper etc. Now I'm questioning the wiring I already have, wondering if it might be the culprit for random problems. I want to find a way to test my current wiring and anything I make in the future. But as anyone with experience knows a cable certifier is thousands of dollars. Then I got to thinking if i have two computers capable of gigabit speeds shouldn't I be able to run a cable between them and verify the performance of the cable? I was hoping someone here will have the experience I lack to make this a reality. Also if it was possible to make a smaller arduino based tool that would be amazing. This seems like a tool damn near everyone could use these days.

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?

My title is a simplified version of my problem. I accidentally clicked uninstall instead of disable on my wireless network adapter. I don't have the CD to install it. My WLAN adapter is a Cisco Linksys WUSB54GC Wireless Network Adapter version 3. I've uninstalled the device multiple times but when I reinstall it, it simply says 'The name is already in use or a service display name' and then when I go back to device manager it says the name of the adapter and then a #14 and the next time I attempt to reinstall it, it says #15 then #16 and so on. What I am doing is I'm going to device manager, updating the driver software for my adapter, then clicking 'Let me pick from a list of drivers on my computer' and then clicking 'Have Disk' and choosing the netr system information file. After that, that's when it gives me the name is already in use or a service display name error. I've reset my computer a couple times, searched bing and google a lot and got similar problems but none specific to my situation. Please help, I don't recall trying to install or uninstall in any certain order so my mess there could have corrupted something, maybe. Thanks!

Hello all, I am having recent issues with my home PC running windows 7. I have working internet with a modem that has a built in router (It's Rogers brand new Hitron modem, the white skyscraper looking one). Here is my current issue. When i plug in my PC through a cat5 cable it seems to screw with all internet connections. It gives me internet for roughly 30 seconds (very slow loads) and then eventually says I am connected to my network but no internet. In turn, this also creates all devices to not have internet acees as well, PS4 hard wired, XBox One hard wired and also my mobile devices connected through the WiFi. If I unplug my PC LAN cable from the modem, both my wired consoles work and can access internet and same for any mobile device connected to the WiFi. I have done a bunch of possibly theories to help renew my ip. All my DNS settings within my network adapter are set to obtain address automatically, i have tried net flushes and release/renew with command prompt.. At one point I reset my modem and created a new network, this seemed to fix the problem for about a day or two, but now again it is back to only allowing me to access internet when i do not have my main PC plugged in. So very strange. Is there something else I can do? Does my computer have a virus that is hijacking the internet? any info would be much appreciated. I am a big gamer and as much as I enjoy the console, I am really missing getting on the PC Has anyone every experience anything like this?

Courtesy of Dr.Professor Jake Biggs, I was able to be innovative with my XBOX 360 and share my dial-up connection with my 360 through my computer. (The instructable can be found here.) However, seeing as I have a unique case, I thought this would be the best medium to use in looking for an answer. So let me explain my situation. Through much effort, I was able to procure the know-how of using my cell phone (LG Env3, not the touch though) as a modem. It is able to give me 7.2 Mbps at all times of the day and night via USB. I then realized it sets it up as a dial-up connection and decided to search out a way to share that connection with my XBOX 360 so as to get XBOX Live. Thanks to Jake Biggs, I was able to succeed in this endeavor. Now I am wondering if there is any way possible to open the appropriate ports under Firewall settings in order to get an Open NAT setting rather than a Moderate one. For those of you who play XBOX Live, you know how frustrating it is to not have an Open setting. Also it would be much appreciated if someone could help me out with the IP addressing. Many thanks to any who come by and put in their 2 cents about this. I'm open to any suggestions or theories.

For some reason my laptop will only connect to an unsecure linksys network and not my own personal, secured network despite entering the network key and the fact that other devices connect to it seamlessly. It simply always defaults to this unsecure network. I've already removed and added my home network as an attempt to troubleshoot the issue, but still no luck. The laptop simply always reverts back to the unsecure network. My home network has more bars and is listed on the top of the list for preferred networks. The laptop in question is at least 6yrs old. Runs on WindowsXP. Is a Sony. Is there something I should do with the drivers or how it is configured.

Question by w1288771 | last reply
Alright, So here goes(Hope this is the correct category): THE STORY I attend a Hungarian conference event held every year along with some of my relatives, family, and bunch of other people i know. The issue is, is that some of the Hungarians who attend this conference do not know the language very well, and require a translator. Our "group" per se, does not yet have wireless transmitter/receiver setup yet, and are looking for a solution for being able to broadcast the English translation to all who need it, without disturbing the actual event. So i began to think. While i was listening to a digital radio station on my mobile device, i asked myself, "What does everybody already have?" Then i realized: A mobile device. I then began to think, "Could i harness the power of these peoples devices, and use them as receivers?" Then the idea grew, and now i am left with this: THE IDEA My idea is to create an application which gives the ability for someone with a mobile device to broadcast audio to other mobile devices with the app also installed that are connected to either the local network (Preferred) or to the internet in general. What i was thinking, is to have the broadcasting device work as a wireless hotspot that doesn't necessarily provide internet, but instead streams the live audio to any other device connected to the broadcasted network, with the app installed. This way, anyone who needs a translation of whatever is being spoken can simply plug in a set of earbuds (And if someone doesn't have a mobile device, use an audio splitter) into their mobile device, and listen to the translator, who is using the mic on his mobile device to speak the translated version of whatever is being spoken. With this, nothing but software and mobile devices (Which everyone already carries around) Is needed. (The conference is held in a different location every year in order to make it suitable for everyone distance-wise.) Think of it as a local network digital radio app. The Translator is the radio station, and the people who need translation are the listeners/radios. THE PROBLEM The problem is, I know near to nothing about creating mobile apps for Android or Apple (Yet.). I know loads about Android, i work with it more than i do with Windows/Linux/Mac/Chrome. I have flashed roms, read into the OS, and done a few other things, but know nothing about building my own APK. Same goes with Apple, except i almost never worked with the OS entirely. THE SOLUTION/ANSWER What i would need, is help from people who have built apps, who know what they are doing, and have done similar things of such category. My free time is limited, and so i can't always be working on it. Nor is this project mandatory, i would simply like it to work efficiently by next year. I would be willing, and would love to learn how to build and design apps, so long as someone is willing to answer my questions. I don't plan on profiting off of this, so don't expect payment. (Maybe a donations page if this all works out, and other people start using the app?) The idea is still just an idea, however i would love to go through with it and actually have an app of such created. Any constructive criticism is appreciated, and if i happened to do something wrong, please notify so i can correct it. If you have any questions, or are willing to help, please do reply!
