By my count that means Pete_B needs to send me his address.
new school ideas meet old school junk.
Not many thinks kicking around lately that need new homes but these might appeal to a few of you.
A customer needed some naked speakerformers that went form -3 to -7dB and I inadvertently calculated and wound a pair that were -3.5 to -7.5dB. Rather than bin them for the copper I figure someone here can put them to good use. Full details of the concept can be found here.
leave a comment with a way to identify you and random.org will pick the new owner mid next week and of course I'll cover shipping.
I have been playing a fair bit with cartridge designs lately and have come to the realization that setup (mainly SRA) can have a profound impact on the sound of a cartridge. When trying to make apples to apples comparisons of different suspension types or silver vs. copper wound coils, small changes in SRA will quickly swamp out the variable you are trying to isolate.
It would seem that something as trivial as a garage door opener would never find its way to these pages but often it is the trivial that gives a glimpse into who a person really was.
This seemingly Rube Goldberg approach to automatically opening a garage door is a testament to the cleverness that was Dennis R. Hoyer. I have no idea when this was constructed but given that they date back to 1926 my guess is going to Sears was not an acceptable option for Dennis.
The key to the operation is the drive mechanism and when I first looked at it I simply thought motor pulled the door open and the casters and gravity did the trick to lower the door with the motor providing some resistive force. Upon further inspection I realized something different was going on since the casters were pointed in the wrong direction.
