In the last week, I've been burned 6 times, shocked once, punctured (with blood) twice, and had to eat a single burger for three lunches in a row. And we are out of ice cream sandwiches. -- John Larkin Highland Technology, Inc Science teaches us to doubt. Claude Bernard

Or were you trying to cook hamburgers and only got three actually done? Perhaps experimenting with electrocuting hot dogs at the same time?? John ;-#)#

And we are out of ice cream sandwiches.In other words, a typical week? :) I have to sort and inventory over 700 reels of SMD components that I picked up, surplus. That will likely lead to a lot of paper cuts. Most are capacitors, from 0.3 pF to 6800 pF. I am waiting on a bundle of 7"x7"x10" boxes that were supposed to have arrived over a week ago. I can put 18 to 20 reels in each box. I already had over 600 reels of components, most of which are full. Ice cream is not on my diet, unless it is sugar free and that is hard to find, since Hurricane Irma.

That's terrible. The ice cream sandwich shortage is at least as bad. You can apply one directly to a burn, or eat it, and either way you feel better. I'm tuning the tempco of my Colpitts oscillator, which is tucked into the corner of a tallish enclosure, so it's really hard to replace 0603 parts; many Metcal burns. Through a modest amount of genius and a lot of experimenting and dumb luck, I've got the f/t curve parabolic with the flat at 40c, and maybe 35 ppm p-p over my operating range. I can tolerate +-500 before my PLL breaks. Spice only helped a little. As Mike E says, the real value of Spice isn't to prove anything, it's to train your instincts. Part of the compensation is, basically, an FR4 capacitor, which has a strong positive cap TC. The issue will be, can I get this sort of tempco in production? I want very constant sine wave amplitude, beginning with the first oscillation cycle. Holding that amplitude turned out to be tricky and of course tangled with the tempco issue. -- John Larkin Highland Technology, Inc Science teaches us to doubt. Claude Bernard

Some 20-something would have et the whole thing. We actually got it in a sit-down restaurant, where sit-down is a table under a tent on the sidewalk. They also had superb beignets with a white chocolate dipping sauce. One side effect of Hurricane Katrina was a diaspora of New Orleans chefs all over the country, people who never imagined leaving but who won't now go back. The cajun/creole effect is very visible. And tasty. We need a modest disaster in Virginia to spread out some good BBQ folks. -- John Larkin Highland Technology, Inc Science teaches us to doubt. Claude Bernard

Oh well, goes like ammo I guess. A poster in the brew NG pointed out another place but I found that their BE-256 yeast was quite old. Somehow production of this stuff must have stopped. -- Regards, Joerg http://www.analogconsultants.com/

How about a little local heat inside a regulator loop that keeps the temperature well above max expected but constant? The heater could be a 1206 resistor. -- Regards, Joerg http://www.analogconsultants.com/
