  1. Well, that guy may be faking it, but I just saw this on Slashdot and the Iphone bit reminded me of this thread. http://www.parrot.com/parrot-ar-drone/en The Parrot website seems to be under a bit of strain at the moment, here's the news article I saw it in, with videos, http://recombu.com/news/parrot-ardrone-iphone-controlled-helicopter-leaves-us-speechless_M11288.html Looks pretty neat!
  2. I've got the same modules and had the same thoughts. I made an Eagle library for the part and will send that to you if it would help? I tried looking for sockets but couldn't come up with anything the right size.
  3. Thanks, lots of usefull info on that page though it seems to lean towards DIY as the best option. I didn't know you could get inserts to do through hole plating. I would much prefer the DIY route but I'm temporarily back living with my parents at the moment and just don't have the space. Xelax: I'd heard of the sparkfun service and found their forum but couldn't oddly couldn't find their website! I'll check it out but would like to use an in-country service ideally. It's a pain getting nailed with import duty and brokers fees... jonforstedavies: thanks for the suggestion, but I've
  4. Hi all, Up to now I have made my own PCBs, but my kit is getting old and tired. I'm also rather limited as I can't do through hole plating or the nice extras like silk screening and solder masks without a heavy investment in extra kit. For anyone interested I found this site ages ago about making PCBs (http://www.thinktink.com/stack/volumes/volvi/pcbproto.htm) I'm looking for somewhere to get a few small PCBs made, typically one or two boards per design. I use the freeware version of Eagle for capture and layout, so the boards will be small So far Top Tec PCB (top-tec-pcb.com) seem
  5. Hi, I just solder up by hand with a very fine tip, but have had problems doing very small chips with 40+ closely spaced legs. I also make all my boards myself with a UV box and etchant, but have found it a bit hit and miss getting really fine pads to etch properly. I found this site a while back which gives details of DIY solder masks, through-hole plating, etc, and thought it was quite an interesting read if only for an insight into the process. http://www.thinktink.com/stack/volumes/volvi/pcbproto.htm I guess it just comes down to how much time/money you are willing to spend on it.
  6. Wow! I hadn't even thought about that, its a brilliant idea! I think I need to make more time to play with this sort of stuff...
  7. Wow cyber-flyer, thats some pretty hardcore stuff! My personal opinion is that the larger distros have become far too bloated and slow, which is part of the reason I dislike Windows! They seem to try to focus on whiz-bang animated graphics which sure make it look nice, but don't add anything to the usability and kill the performance. Almost all of my time with Linux is spend on servers in one form or another, so I usually don't even bother to install X. From the little that I have seen I feel that there is such a lack of standards in the way of GUI design that the usability is really s
  8. Hi JMS, it all depends on what you want to do with Linux. If your looking for a desktop system with the equivalent Office programs then using something like Ubuntu and Open Office should be pretty straight forward. Ubuntu is great for beginners as it introduces you to the programs using point and click interfaces, rather than the command line. Of course there are disadvantages this too, but it's a good place to start. Sooner or later you're going to have to get involved with the command line, and the learning curve starts to looks like a cliff! Don't let that put you off though, once
  9. Hi all, While I am a HUGE fan of linux, just beware that doing anything even remotely complicated with it is likely to require a huge investment of time and pulled out hair. If your prepared to work at it then go for it! It's a really fatastic operating system! Cyber-flyer, that looks like a pretty cool PC to play with, but unless your looking at brewing your own linux distro and getting drivers for as much hardware acceleration as you can lay your hands on, I think you'll run into performance issues. Especially as the CPU is 333MHz. If your just looking to install Ubuntu o
  10. Just a quick tip for those who don't know. If you want to find out if your cheap sunglasses are polarised or not, hold them infront of an LCD screen (eg. wristwatch). If you can see the numbers on the display then rotate the sunglasses by 90 degrees. If they are polarised lenses then the display will no longer be readable. Si.
  11. Just what do they expect to do? Ban GPS devices? Make balsawood and plastic illegal? How about electric motors or small propellers? This kind of technology has been available for a while, and have The Terrorists used it? No. Why bother when there are plenty of simpler and more reliable methods to get the job done, and plenty of willing voluteers to help. This kind of knee jerk politics responding to whatever appears in the meda winds me up no end. Someone needs to be hit with a clue stick. Rant over Si.
  12. Thanks Ox, I tried PCB123 a while ago and didn't like it for some reason I can't remeber now. Maybe its time to give it another look. With Eagle (as far as I know) if you want to use a component that's not in the standard libraries then you have to define your own. You can't just place pads and tracks as you like, they have to match the schematic. (Again, I could be wrong but that's my experience). As Eagle seems to be a popular tool I just wondered if anyone had made a library file already. As you pointed out the datasheet has great info for knocking one up, I just hate doing it
  13. Hi all, I use Eagle for designing my PCBs, and was wondering if anyone out there had a library file for an airwave TX/RX or anything like that to save me knocking one up from scratch? On a side note, can anyone suggest an alternative to Eagle? The maximum board size limitation really gets on my nerves, but I really like the interface! Thanks, Si
  14. JMS, Here's a nice website with info on variable resistors on the bottom half. It should make it clearer what the pins are and which you should use. http://www.st-andrews.ac.uk/~jcgl/Scots_Gu...art2/Page2.html It's also worth noting that there are two types, liner and logarithmic, which define how the resistance increases as you move the move the wiper across the pot. For your application you would probably want a linear one to make it easier to set. Don't forget that the vibrations inside your plane could slowly change the setting over time. You used to be able to get some trim
  15. Now where's the fun in that Out of interest, what kind of backup times do you get with those things?
