Bardwell's is still there, only 300ft from the old premises but now on the main Abbeydale Road. Alas, the junk's a bit more modern and trashy, but I'm sure the old guy in there's the same young guy I knew in the '60s!
Max, what took you so long to find that place? You are trying to think of either Webb or W&W Electronics on Clinton Street. It's too late to buy the 1920s radio on display but you can still look at it.
@radionut - I think the reply only workd for a few levels else the columns get very thin (this used to happen...!)
I also learned a lot from the "In your workshop" columns, they were very instructive. I had quite a few copies of the Radio Constructor - it was another good mag from the old days....
I can't see a "Reply" tab on your recent posting but you're spot on with Dick and Smithy being in the Radio Constructor: their exploits were related in the "In Your Workshop" column and I learned a lot from them.
Ax-man surplus (http://ax-man.com/) in the Twin Cities is always a lot of fun. I put together a TV remote control (read: wired solenoid-based channel button pusher) for my dad from Ax-man parts back in high school. It even sort of worked.... ;)
They have scads of stuff, not just electronics. I just about bought a pair of airline seats as college dorm furniture, but unfortunately didn't have any friends with a pickup truck to haul them to Chicago. Ah well.
By the way, your transmitting tube looks a lot like a 304TL/TH, or something similar but a bit bigger. Those are transmitting tubes capable of plate dissipation of a few hundred watts. Friends of mine used to make decorative mantelpiece displays out of tubes of this class, actually lighting the filaments. Some are fairly bright, but all have a nice warm glow. The power requirements are generally too high to leave them on as night-lights, though ;-) . The 304TL filament is, IIRC, somewherein the 30W range.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
