Hello,
What is new in this 6th edition ?

Big brother is watching you.

I am amazed to realize that I may be the only one in a 5 kilometers radius to dry my laundry using a clothesline.
It is so easy and relaxing to do so whenever weather conditions allow it.
My drier is handy for rainy days, it is not a must have.

Tanks for the photos of the die. A clever 3D transistor, in a planar technology. I remember the first planar transistors in the 60's, a major break through giving amazing characteristics for that time. Planar was the way to go and still going on. Signal low power transistors are very small and extre...

WTF. Here is what I get from the two links:

NOTICE TO USERS IN FRANCE
Because of French government demands to remove creators from our platform, Rumble is currently unavailable in France. We are challenging these government demands and hope to restore access soon.

Great gear.
Does that mean there is no point anymore for us, DIYers, to design and build linear power supplies ?

Important news: travel restrictions lifted from February 25, 2022 From Friday, February 25, there are no longer any COVID-related border restrictions for travel to Iceland. All visitors are welcome, regardless of vaccination status, with no requirement to pre-register before visiting. There is no lo...

I overlooked the non linear conditioning asked on Ec s. In my quick and dirty wave handing solution I was aware of some conditioning but thought it was going to be linear, easily implemented with op amps. I need a close look at the actual gain(Ec) transfer function to fully work out the panning usin...

The THAT VCA: I recall it has two control inputs.
They are both linear giving Db gains. One input goes increasing the gain, the other one goes decreasing the gain.
If this is right a single linear pot could feed the 4 VCAs control inputs to achieve the wanted result.

I imagine there could be more subtle transistor parameters asking for matching.
Early voltage, capacitance,
