I was reading about the gun control legislation that is promised by the newly elected Democratic majority in Virginia. It seems this is angering a number of voters even if not enough to have controlled the election. There have been threats of violence and armed resistance to any new gun laws passed. That is so illogical, the duly elected government, having run on a platform

Hello, I am struggling a bit here to copy a virtual harddisk created with VMDK and a windows 10 x86 installation to a usb stick so the usb stick can booted. So far I have discovered and tried some things: 1. VMDK2Phys tool available on sourceforge. When this tool is used, the partitions of windows 10 are "swapped". Meaning the partitions number are changed from 1, 2 to 0, 1. Not

I am using a programmable thermostat to turn off the heat and/or air conditioning during the peak usage times as set by the ToU billing with my utility. The problem I have is the heat pump not ramping up the temperature fast enough when it comes back on and the backup straight electric heat coming on. This uses maybe three times the amount of electricity during the time it takes t


Noise on VCO voltage ramp

Gentlemen, I've got this weird problem with the network analyser I posted about recently. The problem *seems* to be noise spikes on the DC voltage control ramp which are causing spurious spikes in the frequency domain on the RF output when viewed on an RF spectrum analyser. The peculiar thing is these spikes on the RF output are not random; they come and go according to the point the contr...

A question for all you electronics gurus out there, maybe silly, maybe not. How are transistors designed ? First of all, the SPICE parameters for example for a BJT are obtained by curve fitting experimental test data. So, if I want to design a BJT with a predefined set of performance parameters, how do I start the design task, i.e., start with the Ebers-Moll models, adjosy param...

Hi, Information can be compressed losslessly to a certain density, ie with a compression algorithm a file can be reduced in size, depending on the complexity (information density) of the data. What if the same concept applies geometrically to space and matter? In that case complex configurations of matter and energy would be less compressible geometrically, or have an anti-gravity dar...

Hello, I have successfully virtualized the floppy disk that came with my IOMega Zipdisk Drive Parallel Port version. The idea was to transfer data via this zipdrive without using network technology. The idea was to download the guest.exe software and such to run it inside ms-dos or maybe even a virtual machine. The idea was to download these zipdisk drive drivers from the inte
