Back in the early '60s when CRTs were first married to thick glass faces many older units (mostly TV sets) were junked. At the time I was in 6th and 7th grade in Santa Fe, NM and one of our after-school entertainments was to go to the city dump and drag out old TB sets, position them appropriately in the nearby arroyo, and 'execute' them with our British .303 Enfields. These units lacked bonded safety glass and we removed the secondary safety glass from the front of the cabinets. The results were spectacular - the entire circuit assembly would be ejected from the back of the set - tubes, capacitors, resistors, sheet metal, et al. with a most satisfying blast. This fun was short lived, as the dump attendant, who lived in an old city bus bearing the legend 'Santa Fe is a Nice Place to Live' learned that the TV sets, despite their age, still have some value, and saved them under his old bus. However, he often took an afternoon nap around the time school let out and we learned to drag the units (quietly) from under this bus and lined them up for dispatch - 7 to 8 .303 Enfields going off at once, with the accompanying tube implosions, were usually enough to wake him up, and he would chase us down the arroyo with his 10 gauge shotgun charged with salt shells - these stung like the devil and the welts were hard to explain to our mothers - but the results were worth the risk and we continued our depredations for several months until the dump attendant summoned the city police to help him out - that was the end of our TB implosion experiments.
We didn't have access to the high voltage/current sources of the 'Insanity' person, but it was a good way for us, at the tender age of 10-12, to develop a respect for the dangers of old equipment and those who still valued it.
I used to own an early large screen Zenith color TV with a mechanically operated rotary tuner. As the tuner became old it was possible to get between notches so the scanning coils were unmodulated. This meant the full 30kV was driving the electron beam to a single spot, producing some rather interesting and potentially dangerous radiation. If this guy has the electron gun on and has locked out the scanning he will have most likely given himself a nice dose of X-rays at the voltage he is using.
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.
