PC oscilloscope for Linux Hi, is there any PC Oscilloscope for which there exist Linux software under BSD or GPL or similar license? Naturally if the hardware (FPGA) is documented at circuit level - even better - witch I doubt. I am even open for self construction kits if they are well documented and working. They should use Xilinx ... 28 Feb 2010 09:59
Help: Making Project boxes I need some project boxes and was hoping to get advice on how to make them. I ruled out metal because small PCBs will be the contents of the boxes and for obvious reasons this will not work. That leaves plastic and wood. Has anyone here ever had to make project boxes? And if some I'd appreciate some pointers. ... 8 Mar 2010 03:11
neg ldo problems I'm guessing I'm missing the obvious here. I'm trying to build a discrete negative LDO using a NFET for the pass element. I'm basing it on the internal structure of the UCC284-5 seen here. http://i50.tinypic.com/orkroj.png I've tried inverting the output of the opamp with a BJT but its not regulating. The ... 25 Feb 2010 11:25

Flyback poor regulation I built a 10W multi-output flyback all of my outputs are reasonable except one my -12V output, it varies widely over line and load from -12.5V full load to -18.7 no load. I've been tinkering in spice trying to come up with a low parts solution but I'm not having any luck. I know I can buy an LDO but I don't want... 24 Feb 2010 21:06
