Snoozr Posted April 14, 2011 Report Posted April 14, 2011 The build guide recommends a regulated PSU that is not a switchmode type. Is there any difference between a switchmode PSU and a switching PSU? I'm looking at this PSU. Thanks. http://www.allelectronics.com/make-a-store/item/PS-961/9-VDC-600MA-REGULATED-POWER-SUPPLY/1.html Quote
Flying Panther Posted April 14, 2011 Report Posted April 14, 2011 Switchmode and switching is the same. Main problem is that the switching frequency can introduce noise in the audio channels. I found an interesting read on the difference between lineair and switchmode power supplies. Quote
mazatta Posted April 18, 2011 Report Posted April 18, 2011 This one looks like it will do (9 VDC/500 mA, regulated and linear), provided you live in North America: http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_1953647_-1 Quote
m00dawg Posted April 20, 2011 Report Posted April 20, 2011 Oooh nice find I was just going to make a post about where to find one of these. Thanks for the link as that does indeed look like what we want if I'm not mistaken. In the interim, I have been using a 9V battery to power mine. Only for a few moments though, but I was going to get a few in parallel so I can run it for a good while. I have power bricks I can use in the interim, but they are all 12VDC which seems a bit high, at least for the 78L05. Quote
mazatta Posted April 20, 2011 Report Posted April 20, 2011 Yeah was happy to find it after coming up empty handed on eBay (or at least not wanting to wade through all the crap results I was getting). They also seem to have good options for a sammichSID. Quote
m00dawg Posted April 20, 2011 Report Posted April 20, 2011 Yep :) I bought me a 12V 1A linear regulator for the sammichSID from them as well! Quote
Wilba Posted April 21, 2011 Report Posted April 21, 2011 Please add links to good power supplies to the wiki for sammichSID and sammichFM... I can't recommend any for people outside Australia because I can't test them here. I've added placeholders for the info. Just post your link like this: [[ http://etc... | Name of Store, Power Supply voltage/rating/type etc, Price ]] The "|" separates the URL from the text description. Preview the page before saving, don't leave a mess, etc. Quote
m00dawg Posted April 21, 2011 Report Posted April 21, 2011 Ah *slaps forehead* good idea Wilba! Sorry I didn't just think of that in the first place! I'll go ahead and do that right now. Quote
