ignition system for pyro system

On youtube i found a video of a wrist mounted flame thrower, i decided to make one after seeing mark 3 of the project, i have a basic schematic, yet i lack an ignition system, i need something that will instantly ignite it, the ones i have seen so far need to heat up before they can do anything, so i was wandering about a capacitor bank running from 9v batteries. would that work?, any help would be appreciated. thanks Freerunnin1

rating system

It just occurred to me that Instructable ratings are based in part on the necessity to return to the Instructable to review instructions. Instructables that have steps that are intuitive and/or easy to remember may not get any ratings. In other words good ratings equal Instructable complicated enough to require several visits. That leaves number of views. With a nude or two you could probably get a lot of visitors and a very high rating as well. ;-(

No Help System

Does a REAL online help system exist on this website?  I mean as on any real application program you may be familiar with.  Does it exist and if not why not?  This site is mature enough that it should have a resource which anybody can go to to answer the question " How should work?" or "Does exist?" Up until now the only semblance to "HELP" I have seen is a forum where we all talk amongst ourselves and maybe somebody may throw in a nugget of real fact or wisdom.  But nothing where I can go to get any authoritative information. Why should I have to wait (days/weeks) for a reply from the general hoipaloi instead of getting a (relatively) immediate answer to a simple question? In fact I have been a member for 14 months now and just today is the first mention of the word "staff" have I found.  Staff??  No one in the forum is identified as "staff"! It seems as though no one is running the place. WTF?  Why no real HELP!

operating systems

Does anyone know of some other open source operating systems other than Ubuntu and Linux? because I'm getting quite pissed off at windows 2000. EDIT: there is some confusion about what I meant. I meant that Linux is the only OS that I know about. I didn't mean that I had ruled out Linux, I like Linux, I was just wondering about what other OS were out there.

Rating system

I'd just like to say two things in relation to the new 'view ratings' feature: Firstly, while you can now see who rated your project low, this doesn't mean said person hates you.  They probably don't even remember doing it.  Sure, mention it to them (I myself have sent a few choice PMs), but don't dwell on it.  You have probably done it at some point, and would probably rather forget about it.  See this as a chance to correct your mistakes and give older projects a fair rating if you want. Having said this, I would hate to see people bullied into giving 5* ratings to everything for fear that they may get picked up on the odd 3.5* etc.  As long as you express your honest opinion. But seriously, ratings on this site are typically ridiculously skewed anyway, so I wouldn't get too hung up over it.  Most people don't care about ratings at all.

Rating System

Never mind---just read this if you're bored or something......Canida explained it for me What happened Instructables?! All of a sudden half of the instuctables on this site are boosted up a whole number! My best instructable used to be 4.08 which was very good but now all of a sudden its 5 exactly. I feel the new rating system is too easy and it is making it so every instructable has ratings which are way too high. I cant even sort by rating anymore because there's at least 1,000 instructables that are 5 stars and it doesnt show me the true best instructable of that category! Please fix!

Rating System.

Ok, so 2 days ago, I was looking for the highest rated Instructable, and it was the 'Useless Machine', with around 4.8 stars. Today,  iIooked at the highest rated Instructable, and all of a sudden, there are arounsd 10 instructables with exactly 5*, with few ratings (around 35). The same happened in the Knex section, the 2 highest rated things are exactly 5*, even though I know peoople who rated them 4.5* (me being one of them), the 'Striker' has around 25 ratings- how is this possible? Is this legitimate, or is it a bug? or a hack? I don't know but I want answers!

Arduino messaging system

Hi everybody, Not long ago I had an idea about a messaging system based on a simple client-server architecture. Nothing new so far, but my idea was to optimize any exchanged message or sentence for a 4x20 LCD display, so that an arduino client could be easily coded. In fact, I liked the idea so much, that I already wrote a server prototype, as well as the arduino client. I gave this project the name "C0ldWater". The client is based on an arduino board, which uses an ethernet shield for internet connectivity, a 4x20 lines LCD display as an output device and a ps/2 keyboard for user input. I also bought a VPS, on which I run the server and a blog. You can reach it at and you will find all information and instructions to build such a device, as well as all code to be downloaded. So why am I posting here? Easy question, so here's my easy answer: because I already went through a first sort of alpha testing on my own, but I still need some help from anyone who's interested in this project, to get some feedback about his/her personal user experience in order to understand what sort of modifications I eventually need to implement. Nothing difficult or boring, just connect to the service and use it as a normal user: register, read, send, forward, delete or list messages and so on. I'd like to receive any suggestion, criticism or just your first impressions about the project. For those interested, but without the required hardware, I also wrote a simple linux client that can be downloaded from my site. It just creates two threads, one for receiving and one for sending data. Anyway, if you're still stacked with the win OS, you can download "netcat" and use that to connect to c0ldwater: "nc c0ldwater 8889" or "nc 8889". Thanks in advance to all of you! Cheers

changing the rating system

  After being on instructables I have notice that the rating system is a five out of five system without a way of getting any indication to why the vote count is high or low, On sites like deviant art if you want to rate a drawing the artist has to turn on critiques in which you have to give a 100 word paragraph with a rating on why it's bad or good, so on a site that glorifies Tom F**KING Preston we should have a better system for ratings.    Having a requirement to write well thought out critique or reason why the voted low on something will not only discourage those who go around down voting everything because there jealous or because they want to make there chances of winning a contest higher is silly, it will also help to improve the quality of the instructables by getting proper feed back on what to fix in the instructable. Have the comment and ratting together with a little fair or not fair button with the comment.

Instead of comments branching out with replies to replies to replies there is just the parent comment and a line of replies after it that are all indented the same amount. I'm a huge fan of the change since long conversations with multiple commenters got very confusing and very far to the right. This is cleaner for sure. So have you had a chance to see it in action?

Design for drive system

I have ran into a issue with a project that i cannot figure the best solution for. Here is what i am trying to do. Imagine a pvc pipe setup in a ladder configuration. On top of each side of the ladder system an aluminum angle rail runs up and down each side. On top of this rail system is another square pvc piece with ball bearing mounted externally allowing the pvc square to ride up and down the rail. My issue has come from automating the pvc square to move back and forth on the this rail system. I thought of using a dc motor driving it to each end where a switch would be contacted to reverse the motor in the opposite direction. The issue is getting a motor that has enough torque to move the pvc square with about 10lbs on top of it maybe less and to do this a fairly slow motion. I had thought of maybe using a cheap 540 rc car motor, but this is where my ? comes in. How do i drive the square with the motor with out getting overally complicated. Would i be able to adjust the speed of the motor with a potentiometer? If so would i be able to keep the torque or would that reduce too? Finally is there another option that would be simplier to exectue?
