Wirless Receiver

Posted by -james- on 10/12/2008 at 08:00:56 am in Systm

I have a question about wireless receivers.

I was wondering what the best usb wireless receiver currently being sold is, when I got my PC it came with a Dell wireless 1450 receiver but this is not great and I do not get a very strong signal. Only 1 or 2 bars and a low signal strength in windows where as my PS3 gets 40-50%

It needs to be b and g, my router is DG834N but set for g +b.

Sorry this was meant to be in Tekzilla.

Show Idea: DIY LITEPANEL

Posted by davmoo on 10/11/2008 at 02:04:52 am in Systm

I'm going to guess that the way the Litepanel does it is to simply use a higher pulse rate. Over 75 hertz or so it shouldn't be visible.

Could you please upload a circuit diagram of voltage regulators in episode 30?

Do a web search on 7805 and you will find a ton of circuits!

General Project Procedures

Posted by Dosbomber on 10/10/2008 at 04:06:03 pm in Systm

I like the idea of a "construction tips" episode. There are lots of these tips scattered all over the place, but you'd have to watch hours and hours of video to catch them. It'd be nice to have a collection of segmented clips about how best to do different aspects of a project.

As someone who's built a lot of projects, from a simple PCB-only to a fully enclosed gizmo in a plastic box, as well as wood projects that don't even involve electronics or robotics, I can safely say that I've learned new things or better ways of doing certain things on EACH and EVERY project.

Tekzilla and (ugh) PopSiren have daily tips that are only a minute or so in length. Perhaps these tips could take on that sort of format?

Drilling holes, as mentioned above, could cover several of these short episodes alone. Drilling in metal, plastic, or wood require consideration for hole diameter as well as rotation speed. Clamping the material may even be a one-minute tip in itself. Center punching for certain materials (metal and PCB substrates especially) could be another.

General Project Procedures

Maybe this has been suggested before, but I'd like to see a guide full of tips and tricks that go into making a project fit together properly, and work. Things like the starter punch for drilling a hole in metal, how to use calipers, test cuts for saw blade depth, and conventions for marking cuts.

It's boring stuff and doesn't necessarily make a good show, but it would be nice to see a simple faq of construction tips.

p.s. Great work to the systm team!

Things like the starter punch for drilling a hole in metal, how to use calipers, test cuts for saw blade depth, and conventions for marking cuts. All the tips that we've seen in individual shows.

It's boring stuff and doesn't necessarily make a good show on it's own, but it would be nice to see a simple faq of construction tips that we've seen in all the shows.

p.s. Great work to the systm team!

Show Idea: Pimp your old iMac (G3)

Posted by computoman on 10/10/2008 at 11:34:30 am in Systm

Os/x security wise probably will not be supported much longer the the ppc mac. The last os/x I ran was 10.4.8, but linux runs faster on those old machines. Fedora, Debian, Slackware, Ubuntu, Suse and other linux distributions still support the ppc mac. I ran debian and ubuntu on my 300 mhz or so g3 towers till I decided to scavenge them for parts. When I can get 1+ ghz pc's for free, I did not see any need to support them anymore. If I wanted to I probably could put them back together. If I get some spare memory I might put the towers back available for use. I still have my imac running ubuntu hardy. Getting the video to work in gui mode was so much fun. Besides Mac being great linux media/file servers, they make great oversized diskless thin clients for ltsp using netboot. Yes that is right you can pxeboot macs from an intel box and run linux.

I was till running debian and fluxbox on the imac when I took this picture. It breaks my heart that a lot of schools discarded these units as being worthless and they could have been repurposed with linux to save the school quite a bit of moola.
