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 have an AT&T USB internet card, with unlimited internet usage. I want to know how to set up a wireless connection in my home using the usb as the primary internet source, from my main computer. that way family or friends can just connect to the network from their laptops instead of using my computer, or me sticking the usb into each computer as needed (the thing cost 50 bucks for insurance LOL) I would like this to work like wi-fi if possible

I wanted to ensure that data being tapped on the RX ends can not be reversed and used for data TX, ensuring unidirectional transfer. I have the tap made with Hotside > Hotside (TX->RX-,TX+>RX+) Coldside > Hotside(RX->RX-, RX+>RX+). I would like to know what I would need to put in between the hotside and the cold side to be able a secure a unidirectional transfer.

So if you google "Home networking" you will come up with a ton of articles about home networking "basics", well I have reached the point where basic is just not enough. I have ..... 9 or 10 computers....and I want to do something to expand my network even more (not really in size but in awsomeness), my house is wired with cat 5e and has wireless. I guess im at the medium level of networking knowledge, I dont know how to program unless its HTML but I definatley know my way around a computer. My network consists of three desktops, one attached to an LCD TV as a media center, one is just a workstation and the other soon will be in the gameroom as a media center. I also have three wireless laptops connecting to my wireless router, one operational thinclent connected to my FTP server through RDP and two networked printers. I'll attach a diagram
Question by bwpatton1 | 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 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 | last reply
I worked with a local business for 2 years helping to set up and maintain a long range wireless network system to provide DSL internet to rural people. It reached over 75 miles from end to end with several offshoot branches. The owner applied for an extension on a Small Business Incubator loan that had come due and for some reason they said no. They called in the loan and he shut everything down because he didn't have the cash to cover it. Anyway, 2 years later and the dust and lawsuits have settled and my former boss has asked me to sell off all the salvaged and new equipment for whatever I can get for it. Much of it is going to be going on E bay. But before I start with that I thought I would give the instructables community a first chance at it. I do not yet have a full list of the equipment, some is still out in the field yet to be recovered, and the rest is on its way to me from our former building to sort and evaluate. If you are interested please leave a comment and or send me a message. Some of the new radios will sell for a fair amount, although not as much as if you bought it from the manufacturer. Some of the well used but functional stuff will sell pretty cheap. What is included : Our radios have a reliable range of 25 miles, with directional antennas. The picture is the mast on my house. Some radios are 2.4 MHz and some are 5.8. The 2.4 which is the standard frequency used for normal wireless served as client radios. The 5.8 ones we used for long reaches to connect the backbone. They can act as bridges in a network or as access points. All have built in router functions. It takes 2, one to send and one to receive to make a network bridge. What can you use them for? They can link up buildings across cities or towns or anything that is in line of sight. We set up an Omni from the internet source and then tasked the surrounding radios to it. One central omni radio can connect with 200 or more clients. The local school district uses this same technology to link all their buildings together. With just a couple of them you can link your house to your friends house miles away, and have a local LAN with them. They would work for extending LAN game play. You can link your house to your barn or shop or whatever and share your internet through a router. There are lots of possibilities. We have the radios, the antennas, the cabling, even antenna sections, but I don't know if those can ship UPS. We have it all and its all going to go, which is sad to me but good for you. Possibly the biggest plus is that I will provide you with some tech support to get it up and running if you decide to get anything. I can also pre program the radios here so they are matched and set to link up for you once installed. So, let me know if this is of interest to any of you. I believe the shipment of these radios is limited to the US and Canada but I can check into that if you are from outside those areas.

Question by tavofla | last reply
Hello! I sure hope this qualifies as a Tech category! I'm looking to build (or possibly buy) an indoor digital thermometer that transmits the temperature information to my computer over the internet. The goal is to be able to check the temperature of my house while I'm at work, or anyplace else with internet access. Do any of you know of a simple way to build this? Has it been done before? With temperatures here in Washington DC breaking records this week (over 100F) I'm worried about my pets health at home, and more worried that the a/c will go out while I'm away and I'd never know. This could result in the death of my pets, and I'd love to be able to be informed in time if something were to happen and the temperature rose suddenly (or dipped, in winter). Help in the right direction is greatly appreciated!

Hi everyone.... I like ethernet related project with Arduino and Arduino Ethernet shield. So now I want to open you a network relate problem. As you know or not Arduino Ethernet shield is made from TCPIP Hardware chip (W5100 of Wiznet Company) and other component. Recently I heard that TCPIP Hardware stack (with Hardware chip) is more stronger than S/W stack from networking attack such as flooding, spoofing and so on. But I want to know technical basis why Hardware tcpip chip is "Unattackable" from networking attack. If there is a anyone have a knowledge about networking via internet... please share your knowldege or your thinking.

Hello, I have a Toshiba portege m900 laptop. After a couple of years of connecting properly, it suddenly cannot connect to my home network. It just says Connections are available and displays the home network, but when I click connect, it eventually returns with "windows can't connect to ". Other wifi capable devices in the house connect normally, just as they have done before. The laptop can still connect to other networks that I have access to. When I start the troubleshooter it returns with 1) Windows cant connect to the hidden network , 2) problem with wireless adapter or access point 3) A network cable is not properly plugged and may be broken. I have been downloading large-sized files before the time I can't connect. Does it have anything to do with my sudden disconnection? Thank you for your help!

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?

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?
