Snubber network? Answered

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?

Can anyone suggest a good current book on understanding networking, Wired & Wireless?

I have a basic knowledge of networks but I need to know more without having to go to a year worth of classes. I know how to pick the right hardware, run wire, setup a router, but if I needed to troubleshoot why tcpip is not working, why the speed is fluctuating I'm lost. As always, Any suggestions are greatly appreciated.

Social Network Hackerspaces?

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!

For Sale-- Long Range Wireless Networking Equipment --- New and Used

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.

Indoor Thermometer - Check temp at home while at work

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!

Networking, Subnets and Basic Routing - Please Explain? Answered

I have been having trouble setting up my router so that it knows about a network behind another one my routers (serving up another subnet).  I understand a little of how to configure the routing tables but I was wondering if someone could just explain the basics of how an ip network (subnets/subnet masks etc) works, as it is still a little mysterious to me (it's amazing that I have been able to get things working with my limited knowledge). I mean how does one computer talk to another on the same subnet or across the world (what is the difference between a mac address and an IP address), what is going on behind the scenes??? I don't mind technical speak as long as it's logically ordered.  Thanks so much!

Router antenna hack (two to one)?

I'm in the process of buying a router to add custom firmware such as ddwrt or tomato. Some of the routers have two antennas but I'd like to use just one in order to use it with a high gain antenna. I understand that some routers have a way to disable one antenna in their firmware but I will be using custom firmware. I also understand if one antenna is not disabled in software both antennas needs matching antennas so impedance matches. If impedance insn't matched antenna would not work for long.  My question is could I not just bridge one of the antennas on the pcb to the other in order to have matching impedance?

Network ON/OFF Switch with Timer

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

Instructables App "network error"

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.

Redesign instructables to make searching easier and more practical!?!?!?

I'm fairly new to instructables. i've only read about 100 or so and not made any myself. for the most part i can rarely find an instructable that is of high enough quality end-product or end-result for me to commit to making it instead of starting from scratch and designing my own thing, or buying something that has already been produced for a more affordable and higher quality end-product. but there is one huge reason i remain committed and interested in instructables as a website and a community! my dad has a garage full of high-potential junk! now if only there were an easy way for me to search instructables for projects based on my plethora of ingredients (inventory) rather than typing finished project titles or end-result names of creations into the search bar. i understand that this may be extremely hard to do since there may literally be an infinite number of names and objects, not to mention the various languages, misspellings, and misnaming of objects and processes that would need to be accounted into the search process as well. the idea would be that instructables users could rack-up all their junk and save it as a list to their own digital library or, "inventory" of all the parts and tools they currently have and manufacturing processes they can do with said items. from there they could click "search by inventory" and include or exclude items from their total inventory to run a search based on that. for example i could select: -super old motherboard (or specific part number) -old motorcycle seat -some bolts (or specific sizes of bolts) search results would turn up projects based on the parts that i have selected, results would mention whether i am missing or have all of the tools or parts i searched for. imaginary examples might be stuff like: -strange computer motorcycle seat -cyborg motorcycle seat -a computer build from an old motorcycle seat -ride fast while computing fast -tune your old motorcycle with an old under-the-seat DIY ECU -etc. though, this sounds like a daunting task, especially with the numerous vague and sometimes seemingly useless projects people can come up with, instructables has already begun to specify categories and sub-categories (channels?) of project styles such as leather-work, CNC, electronics, wearables, etc. etc. and to add tags and specific names for parts, tools, and processes to a library would simply be a more detailed and concentrated addition to these categories. what i'm hoping we could maybe do is add an option to search by ingredients in a similar way to how myfridgefood.com searches for recipies (maybe we could start by adding a similar function to instructables' recipies category?). it's just an idea and i'm not sure how willing the developers of instructables are to allow this community to contribute to the redesign or addition of search options.  aside from searching by ingredients, it would be extra helpful to know if there are other instructable members in our local neighborhood who are willing to collectively use their junk to make a project together! combined inventories could lead to a world of possibilities for creations and networking! maybe one person doesn't have enough junk to make their own forge but a whole neighborhood would be willing to contribute their efforts to make a community forge? i know my dad isn't the only one in our neighborhood with a garage-full of junk, and i think with everyone's junk maybe we could send a project to the moon, or make a super awesome rat-rod, or make a community wind-turbine farm, and get all that legally approved by our local comminity! maybe as a neighborhood we could create something only large companies are currently capable of manufacturing!?!?!? and finally on a side note i think maybe there should be a filter between serious and non serious ("fun") projects. or at least a rating service so that readers can scale how serious they think a project is on a serious to fun scale with fun and serious being in the middle. that way everything stays positive and constructive; no negativity for being too serious or too fun! yeah that last idea is pretty crazy, but maybe we could start with my first small idea of searching by parts/ingredients? let me know your thoughts! thanks!!! (expecting answers along the lines of where to start, whether or not other instructable-type websites exist, i know for a fact this is possible and doable since myfridgefood.com basically has the format set up to do so.) i'm open to (negative) answers that completely tear apart my idea as long as they are educated and provide specific counter-reasons as to why it would not work. i'm fairly certain the first idea is possible, it's just a matter of convincing the developers to get on board and getting everyone to start labeling the parts, tools, and processes in their projects (they are already "tagged" maybe we could start there?)

Wardrivers :/

Last night while collecting the mail, I noticed a glow coming from inside a car. The guy was sitting in the drivers seat with a laptop, and had a small antenna stuck on the roof of the car. He was running Ubuntu and was trying to connect into my wireless network. (WPA2 thankfully). I could even make out my SSID. I thought of knocking on the window, but I had a better idea. Went back inside and disconnected the modem from the router (just in case), and booted up a LiveCD of Puppy Linux. I created a ad-hoc wireless network as bait and waited. 5 minutes later someone was connected. The user connected was Darren-Lap. I got his IP address and managed to SSH into his laptop without any password prompts. Quick Google to see if I could send him any messages through the Terminal. Found a method and sent him a message saying if he didn't leave in 5 minutes there would be consequences. His reply: "F**K YOU! Suddenly the firewall was getting a lot of hits.  A simple "sudo rm -rf /" command sorted him out. (http://is.gd/fE7cL - demonstration) So here's a tip: Try to hack into my network, and be prepared to lose. :)
