What's in those "45 in one" sensor kits?

[@jamess1787]

Local here, you pronounced it correctly. Way to go! You must be a Canadian! Thanks for the video!

[@thisissoeasy]

Really great, very useful video!

[@martinmoore4333]

great video really useful as when buying all these kits we are left to figure it all out for ourselves,

[@frankowalker4662]

I might get one of these kits. I don't use Arduino, but they can be used for all sorts of projects without one. Great vid, thank you.

[@AnotherMaker]

Great video. It's funny...as many sensors as I look at, you had some form factors I've never seen before in there. I've never had the 2 color leds in a kit. Never had the auto changing leds. There were a few others that were unique at least in design. Excellent explanation.

[@pileofstuff]

Yeah, I'm not sure the arduino related value of the colour changing LEDs, but they are fun to have - especially in large numbers.

[@GnuReligion]

@@pileofstuff Never can have enough blinky. My favorites are 2-pin, 2-color ... useful for indicating polarity of a stepper coil.

[@HazeAnderson]

I snagged one of these kits too .. thanks for the tip! :)

[@stevetobias4890]

I have one of those, I paid a bit more for the case and a lot of the modules were slightly better quality.

[@ronm6585]

Cool kit. Thanks for sharing.

[@charlie1872]

Good morning, I may have told you I worked in Winnipeg for two years working on the design of the Keeyask Hydro Dam project. I have Triang Hornby trains, would you know if it would be easy to build a re magnetizer like the Hornby Dublo one ?

[@ralphyrocket5770]

beer and electronics!! my kinda friend!!

[@rednerdnecktech2474]

These kits are a lot cooler than reading Forrest Mims articles and putting Heathkit kits together. Puts my old 200 in 1 science fair kit to shame.

[@adam850]

Any of the modules you'd consider to be fillers to bulk up the advertised number?

[@pileofstuff]

Maybe the duplicate microphone boards and duplicate 2 colour leds, but other than that a new person could learn something from all of them and build a good variety of projects.

[@fumthings]

hey, when did the LED coaster disappear?

[@pileofstuff]

I made one with my own logo a few weeks ago, but the light-up Simple Electronics coaster isn't gone - its just off to the side a bit

[@HazeAnderson]

Haha ... just thought of a trick circuit we can build using a Hall sensor. Build up a little noise maker that only emits sound when a magnet is brought near the sensor. Show it to your friends but don't show them the magnet cleverly hiding in your hand! Scuff your feet on the floor first and tell them they have to build up static charge! 😆🤔

[@TheEmbeddedHobbyist]

I was expecting about 23 parts, as the Chinese always over state capacity. A good way to calibrate a temperature sensor, water always boils at 100°C and crushed Ice in water is close to 0°C great kitchen table top cal methods. My alarm uses hall affect sensors, and will indicate a tamper condition if the magnetic field changes. Reed relays are so old school :) Nice looking beer.

[@celtisafricana4984]

Boiling point of water can vary greatly depending on a number of factors- air pressure/altitude, contaminants, etc. Same for freezing point... can be affected by contaminants. There's even an obscure method of keeping water frozen at room temperature

[@TheEmbeddedHobbyist]

@@celtisafricana4984 The point is the boiling point is a constant for the air presure you are at. You can keep trying to increase the heat the water will only boil at a steady temperature unless you change something. So a reasonable calibration value. Something everybody has access to at home.

[@stevetobias4890]

While reed switches may be old school, they are a very good switch with a small cheap magnet for a cupboard light and many other low tech needs.

[@TheEmbeddedHobbyist]

@@stevetobias4890 we used them a lot in waterproof microphones for the Press To Talk function. Sliding magnet outside of the rubber covers, and RF switches inside coax cables. old school and still so usefull as you say.

[@jayherde0]

Two questions. Is the RTC still on time? ... I know, I may have missed it. But we know about OCD ;-) .... The real question is - How much time did you actually spend making this video? (not counting post production.) ... Just wondering.

[@pileofstuff]

It took about 3 hours to record and probably 5-6 hours to edit. I'll have to check the RTC in a few more days and see how close it it - though they're usually pretty good.

[@andrewkieran8942]

@Jay Herde, please call it CDO, because that's alphabetical order.

[@electroniquepassion]

👍

[@garyhart6421]

I took an old Mercury Tilt Switch from a Thermostat and put it on my Bike to sound its Air Horn if moved --- LOL

[@KARLLARK100]

good day 33.06 mins of pure fun thanks,.//.,

[@W8RIT1]

As a side note... That's the incorrect way to pour a beer. I used to do that for years...a sommelier explained to me why. Let me find another video to show why

[@duanecjohnson]

The tilt switch could be GALLIUM instead of MERCURY. I got a bunch of gallium ones which are quite safe. redrok

[@pileofstuff]

Interesting. I hadn't encountered that before.
