And now Rev. 2.2.
I switched back to the DIP version of the LME49710 as TI brought it back to active (= in production) status. I also implemented some of the lessons learned from the Modulus-286 in the DC servo. Further, I was able to reduce the BOM cost by about $5, which I quickly added back in by adding a small sleeve of thermal paste to the BOM. 🙂
The BOM cost is just shy of $50 (including $4 in Wakefield 120 thermal paste).
It provides the same performance as Rev. 2.0 and 2.1. It's just easier to assemble. Quite a few had issues with the TO-99 can package as it's the only IC package where Pin 8 (not Pin 1!) is marked.

I see I still have some way to go with my soddering (or soldering in Canada?) technique.
Nice.
Nice.
All I can say is 'you lucky bastrad'. I'm running on 4-5 hours a night at the moment. All self inflicted mind.
I hear ya, my wife still jokes about my daughter rooting on my chest as I snored away so she could sleep.
My Scottish coworker says that ALL the letters in "solder" are pronounced and we Americans are incapable of correctly using the language.
Or electric glue applied with a sweating peg 😀
Solder = sol-durr or depending which parish you hail from, soled-her.

Just wait till we try and get you to say 'Al-oo-min-eee-um' not 'aloominum'
As Marge said 'In England a sidewalk is called a pavement, a trunk is called a boot and botulism is called steak and kidney pudding' 🙂

Oh sure. I've heard of it. Comes in foil form.... 🙂 Useful for shielding prototype circuits.
You also have prohjects rather than prajects. For a while I was trying to figure out if there was a Canadian dialect or accent. I gave up. Given the influences of the Irish, English, Scottish, and Americans the pronunciation shows a lot of individual variability. You then sprinkle on some Canadianisms and local slang and you have a royal mess. "Hang a Larry on 16th AVE" or "hang a shithook". Good times. 🙂
My favourite is the verb 'table'. As in to table an offer. In the US, if you table an offer that means you take it off the table. No longer available for discussion. In Canada (and UK also I think) it means the opposite - i.e. put an offer on the table to discuss. Scared the crap out of me when the postal workers threatened to go on strike and Canada Post tabled their offer.

Here in Carolina the natives say "sorder"
Congrats on the new Rev Tom!!
I'm still enjoying my Rev 1.0!
Thank you. It turns out we cruised past the three-year anniversary of the Modulus-86. Rev. 1.00 was put into production on July 20th, 2014.
Thanks to all who've contributed, helped, and nudged me in the right direction over the years.
