I'm trying to run my NSLU2 (with a 1GB flash drive, connected to an old wifi router) from a 12 volt SLA rechargeable battery (5Ah) using 7805 voltage ...
Hi Must admit I'm somewhat rusty on my electronics theory. Regulators are rated with suitable heatsinks fitted.They are very derated without heatsinks. Various...
This is the worst way to make proper 5 V supply from 12 V battery, because 60% of power from battery is chaned in to heat not in to power necessery to supply...
Efil, 12V-5V=7V 7V*1A=7W (heat!!) 7V*1.5A=10.5W (even more heat!!) ... when I turn the NSLU2 on, after about 30 seconds, the regulators are too hot to touch...
... Further update .... despite my initial optimism that after complete reinstall of original linksys firmware and unsling process that system was ok I found...
Is there any particular reason your trying to run this off a 12Volt battery? If you need 12V to run the rest of the project.You could have two 6Volt batteries...
Thanks for all your responses. I'm using a 12V battery because it's what I happened to have on hand. The NSLU2, three Arduinos, and a few various ICs and LEDs...
One option worth considering is a switching regulator. These have the huge advantage that they are efficient so don't create all that waste heat and could...
oabroad: a schematic and parts list would be great. I've been fiddling with other ways; if I don't have the parts to make a switching regulator, I'll probably...
... OK, this is going to be a long post, mainly because I don't like saying that something is going wrong, I also like saying exactly *why* it's going wrong ...
... Take a look at this: <http://www.romanblack.com/smps/smps.htm> It's a two-transistor (plus three resistors, three capacitors and a Zener diode) switching...
Hi there guys, take a tip from an old H/W engineer: surf to the National website (www.national.com) and then go on the webench design software. Fill in Your...
First off, I'd like to thank you all again for your help. I should have done a bit more research before jumping head first into this project. Next time around,...
I just remembered a design trick for boosting a regulator: one circuit I've seen used a PNP power transistor with the base connected to the INPUT of the...
In nslu2-general@yahoogroups.com, "efilvasers" <efilvasers@ ...> ... You might want to take a look at www.national.com and use one of their simple switching...
... Hello Brian! I tried to edit the page, but it seems that I need to be a registered user. How can I do that ? Regards, Manuel [Non-text portions of this...
OK, so I am a complete newby at unslung. Here is what I did. 1) I followed the installation instructions to install unslung. 2) When I installed I put the...
Hiya. Have a nslu2 with with the latest version of unslung 6.10. Have done the modifications to the samba files so the pocket pc can see the slug, and i get...
Hello, I've spend some nights to understand why the slug have this currious behaviour.. In fact, when it reboot a little error of mounting partitions cause a ...
Hi, My problem was simple, before I bought a NSLU2 I have two big USB drives pluged on my own PC. This PC assume to share the disk contents on my personnal...
... Why on Earth do you need to do that? At least on all of my Linux systems when I edit a file it stays changed. BTW. I believe the correct file to edit...
Hope this is allowed... I have just put my Unslung slug on ebay - if anyone's interested. For sale complete with the Freecom 80G H.D. it is unslung to. There's...
I read that I need a 2.5mm plug at 5v dc and 2amp to fit and run the NSLU2 correctly. So I saw and bought this: http://cgi.ebay.com/ws/eBayISAPI.dll? ...
... I agree with you, but the file /etc/samba/smb.conf is created on boot by the NSLU2 firmware in fonction of group, users and shares. So the security...
... boot by ... I've never had my /etc/samba/smb.conf overwritten, but with so many different firmware's to choice from, I guess the one you picked does. In...
... If you're in the USA, I would suggest going to Radio Shack. They can probably match the NSLU2 native power connector. They sell connectors that you can...
