I designed and made this PGA2310 module. It uses an Arduino to control it :) Some details here: http://nospecifictopic.blogspot.com/2011/01/controlling-pga2310-with-arduino.html- MaxW

My first completed PCB design, High End LM317 regulator! Ready to do the first PCB!
Wow excellent results for your first PCB! I've had the drilling problem before too. You can make the pads larger so that there is less chance of lifting the trace but if you want to make an SMD version, look for the SOT-223 packaged LM317: The schematic would be the same, just...- MaxW

My first completed PCB design, High End LM317 regulator! Ready to do the first PCB!
With a simple regulator design it might be easier and cheaper to just get one off eBay? http://cgi.ebay.co.uk/LM317-DC-5-24V-Out-2-5-12V-Volt-Regulator-Converter-/230586703745?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item35b009df81#ht_6415wt_957 ...- MaxW

LME49860 class A bias with cascode SMD JFETs
Quote: Thanks for the reply jcx. Well its a line stage so the load would be small compared to headphones, like 10-50k, that of a power amp. Can you show me a schematic or a link to a "ring of two bjt feedback ccs" example?- MaxW

LME49860 class A bias with cascode SMD JFETs
Hi, I'm designing an LME49860 based linestage which I'd like to biased in to class A. I think I'll use the cascode JFET method, ala the PPA. I just want to be sure I've selected the right transistors for Q1 and Q2. I want to use SMD components, I've read Tangents documentation and think...- MaxW

Arduino based passive analogue input selection & volume control
Well for what its worth here is my design, still waiting for some DIP switches to arrive (for setting the I2C addresses) but I've tested it and it works really well! I'll have a few spare PCBs if anyone is interested.- MaxW

Arduino based passive analogue input selection & volume control
Sorry to bump an old thread but did anything become of this? Just curious as I've designed pretty much the same thing, got PCBs and just waiting for some components to test it out....I'll use an Arduino too.- MaxW

Great work Nisbeth You should put some clear coating on the copper if you havn't already as it will tarnish very quickly- MaxW
