You'll need to follow the pot you use with a buffer as well, if you're going for cable runs over 1m. A simple unity gain opamp would suffice, or...
Other way round, that would be an ADC. It takes the digital output from the computer and outputs the analogue signal. It was designed to get round...
Hi there, I can't remember if I posted this here or not. Anyway, what it is a very high quality audio DAC using the USB port as it's source. It's...
Shipping is pennies to North America, that's not really an issue. I'm not going to need it until december, so I'll look into getting them done,...
Well, if I got 25 PCBs printed professionally, they'd come to about £3.10 each plus postage. Component cost is only about £5 or so, so total cost...
Schematic as promised: [IMG] not much interest so far... g
Hi all, just thought I'd post this little design I've been working on over the last couple of days. I'm going to put together a PC that is silent...
no, I'm just saying that for the hassle involved getting a Jung working properly, and the fact it will cost more than an LM317-type as you still...
to get back on topic, there's no problem per se with a Jung regulator, I use one myself but it's certainly more awkward to use than, say, a...
harsh perhaps, but if you're asking that question it probably means you're not ready to build one! g
it depends on how thick you tin the copper. For a normal circuit you'd get from a PCB manufacturer, the tin layer is only about 10microns thick....
tinning is to ease soldering and prevent oxidation of the copper. It doesn't affect the current carrying ability at all g
the Jung is NOT a good option unless you really know what you're doing and is very temperamental regards opamp choice, current draw and...
you don't bias to the current limit of the opamp, otherwise it would drop from class-A operation with any input, 1-2mA will do nicely. Taking the...
Q1/Q2 bias the opamp into class-A, meaning that the output transistors are always on so you reduce IMD significantly as the transistors aren't...
everything is on the board, ie; feedback resistors, power caps, 4x stacked buffers, opamp, class-A bias, LED, 1/4" output jack, and ALPS Blue pot....
don't bother with the DIP16 amp, I'm not a fan of that method of construction: looks like crap, almost impossible to debug, and prone to shorting...
ok, thanks for the suggestions folks! I'm still unsure of the processor issue, as the KT7 doesn't officially support the T-bred core, but I've not...
Hi all, this is my first post for a long time here and I've sort of fallen behind the cutting edge by a long way! I'm moving away next year and...
not true, all headphones will happily handle the output from an MP3 player... check for a DC offset in the output from the MP3 player, as this can...
