The Sunbeam T20! No buttons, just drop the bread in, it knows what to do. I got frustrated with the $5 hardware store specials. Through a process of deductive reasoning, I surmised that it was extremely likely that some sort of “obsolete” though completely reliable vintage device must in fact, due to certain laws of the universe, exist. Made back when the chrome was thick, and you know. A few clicks on the internet and there it was! They probably keep one at the Museum of Modern Art. Raymond Loewy. ---

I nominate the adjustable competition style kettlebell. Others have made adjustable bells before, but the competition style has the weights inside of a hollow, competition sized shell. This makes them easier to store, and all of the movement patterns remain the same, no matter the weight. The one from Bells of Steel has .5kg and 1kg plates, so you can go from 12kg-32kg in very small increments (41, actually.)

Dryer thermal fuse. If the dryer gets too hot (by a clogged vent, for example), the fuse burns through and cuts off power to the heater. Simple thing that prevents house fires. Cheap part. Easy to replace. ---

About the toilet seat. We have one, and the mechanism just seems to be a viscous hinge. ---

> [@burpo\_the\_wonder\_mutt](#): > > The rear view mirror in your car. The kind you flip the tab to keep from being blinded by the mook behind you with his high beams on. They’ve taken it to the next level and now the rear view mirror (and side view mirrors) can auto-darken based on the intensity of light hitting them. Pretty spiffy.

> [@Chronos](#): > > The repair job after it’s triggered costs nearly as much as a new saw. Still cheaper than a finger, though. I have a SawStop and have triggered the safety mechanism twice. One time the blade nicked my alumninum miter gauge fence and the other is when I wasn’t thinking and tried to cut some thin sheet metal. I want to say the replacement brake is about $80 (or was) and the new blade costs whatever you want to pay for one, but the ones I buy are $20 - $80. ---

I was hoping it would hold commercial-sized tri-fold paper towel packs, but alas, no, wrong dimensions. Just super expensive $4.49 for 60 sheets.

> [@needscoffee](#): > > (It’s intended for countertop, but towel rack is an interesting idea.) Huh. Intended for countertop? I guess my mom came up with the idea of dropping the angled part into a towel rack. Then it stays stable and the towel is dispensed from the bottom. ---

Here’s a seemingly trivial example that’s a good illustration of how technology sneaks up on us: flashlights! I mean, what’s to improve on? You stick some batteries into a tube, press a button, and you get light! You don’t have to be very old to have flashlights from that era. I still have a couple of traditional Maglites, which were known for their build quality and quite expensive. I recently got a couple of new ones (not Maglites) because it’s always useful to have flashlights around the house. New technology and some design thought have made awesome differences: - The new ones are pocket-size – less than 6" long, about the same length as my mini-flashlights that take two AA batteries but thicker because of the robust Li-ion battery – but the LED beam is at least as bright as my traditional big Maglite with four D cells. - The beam is adjustable from wide to very narrowly focused and distance-penetrating - It has a heavy-duty rechargeable Li-ion battery claimed to provide sustained illumination for 17 hours. It has four little blue LEDs indicating charge status. It’s rechargeable via USB. - It’s rated IPX6 level waterproof Maybe a kinda silly example, but it’s amazing how far these simple but often essential devices have come. It also has a range of brightness settings and strobe/flashing modes, achieved by successive presses on the power button. So how do you turn it off without cycling through all the modes? Another thoughtful and simple design choice: after 8 seconds in any mode, one click turns it off.
