@TechConnectify yeah youre right i should check up on my automated personal backup routine in a minute-- wait what kind of backup are we talking about again

Guy Dupont@TechConnectify may I humbly submit some ideas to disrupt this space:
I hacked my wife's car to make it "less" annoying.

Nick's world@TechConnectify Now this is some interesting stuf. I never knew any of these things.

In my experience more than half of the car drivers are worse than the average driver! 😆
Way more...
@LukasHvG @TechConnectify which might be correct if the repartition is not evenly distributed ^^
@TechConnectify For No Effort November, that backup reverse/reserve joke was amazing. I'm sad to think of how many people won't even realize it's there. Also, at some point, I'd love a video on how beepers work in general. You said something about DC into a board, then a word I don't know (mosfet?) then it beeps. A lot of things can beep, but can't produce other sounds apart from simple tones, and all without microcontrollers. How does this actually work?
@alexhall @TechConnectify I'd also love an Alec take on simple timer circuits and where they show up.
Here's my understanding of Alec's non-microcontroller explanation (in not an expert):
A 555 timer is a simple integrated circuit that can act as an oscillator - turning on and off at a regular frequency. This can be quite fast - fast enough to pulse a speaker and make noise.
He then mentions using capacitors and a transistor and junk to drive the speaker quasi-directly - this could be a reference to using the 555 timer's on-and-off to trigger a transistor that connects 12v directly to the speaker (rather than the 5v the timer spits out).
Then mentioned is a thermal switch - the 555 by itself will just make a continuous noise through the speaker - to make it beep, you need those pulses to stop and start regularly. You could achieve this with a thermal switch - it heats up, disconnects the circuit, then cools down and reconnects, repeat. Or, you could just use another slower 555 timer to turn on and off the first 555 that's making the noise.
Turns out they just used a programmable microcontroller to do all the 555 stuff (make the sound and switch regularly) as they are pretty cheap now, and the MOSFET is the transistor that puts the 12v to the speaker.
I personally love doing things without a microcontroller, it feels so satisfying working directly with the on-off logic.
@young @TechConnectify I think I mostly followed that. Really, a video covering non-microcontroller electronics would be cool. Beeps, LEDs flashing in specific patterns, timing, all that. I'm not a hardware guy, I'm more about software, so I get logic gates already. It's the rest of the circuit that's a mystery.
run_atalanta -> beige.party@TechConnectify BTW, I was looking for geegahs for an art car road rally, and I found a backup alarm that literally is a “childs voice” saying “attention, attention, this car is backing up!”
When I went to add it to my (rustoleum safety yellow) moving piece of junk, I discovered I was only getting about 7v to the tail light. (sadness). Child wouldn’t speak.
makeasnek@TechConnectify Great episode I love no effort November!
John M. GambleI'm looking forward to the option of selecting the Al Hirt version of Flight of the Bumblebee for my car sound.
gigabecquerel@TechConnectify Ahh, the puns in this one!
I love it, well done

> half of the drovers is worse than an average driver
It depends on definition of „average”.
@TechConnectify fog lights aren't break lights, they have much more powefull bulbs.
The Apostle of Conscious Dying@TechConnectify woo! i love no effort november.

ChurchHatesTucker ☑@TechConnectify If we're going to standardize a backup sound, the superior choice is The Macarena.
Chloé Raccoon@TechConnectify "bloody obvious" Are we infecting you with UKisms? (Good ;)
Mike [SEC=OFFICIAL]@chloeraccoon @TechConnectify sounded very appropriate to Australian ears, also. The tides are turning in the culture wars!
@mike @TechConnectify Due to my interactions with a couple of Australian comedians, I have this mental image of the antipodean version being a looped recording of "I'm in reverse ya cunt"
@chloeraccoon @TechConnectify as an Australian comedian I can confirm this is indeed how it works, but we have not yet mechanised the process.

@TechConnectify I remember, when I was maybe 10 I asked my dad if the reverse lights are for lighting the way, or informing other people, and he said "not sure, probably both?" And now I am finally getting a longer reply, thank you for answering my question from 25 years ago.
InsertUser@TechConnectify passing on the left could get me in trouble. 🇬🇧
Pierric@TechConnectify don't worry you're better than Tom Scott. Also, can you explain why I don't get electrocuted by the battery when touching my car? It's an unsolved question I didn't know I had, and it's your fault that I now do, so be responsible.
Gentle Golem@TechConnectify Love that 'no-effort' doesn't apply to the fabulous puns. Either that, or you're so good at puns they're effortless, and if that's the case I've got an event you should attend: https://www.punoffatx.brushsquaremuseums.org/
O. Henry Museum Pun-Off World Championships | Austin, TX
The Grand Daddy of all pun competitions is in Texas, in Austin, naturally. Is it the best? Yes. Is it the oldest? Definitely. Is it the funniest? Easily. The O. Henry Museum Pun-Off World Championships have been around for 45 jears! it’s hard to imagine one more refined. For Texans, anyway.
xanna@TechConnectify Recorded messages are not uncommon in the UK and Ireland IME. About 15 years ago I lived near a Tesco and their delivery lorry would frequently back up by my house. A voice would say "This vehicle is reversing!" in a posh-sounding voice with a very surprised tone. This turned into an in-joke with my housemate, "I say old chap, this vehicle... it's... reversing!" Other recorded messages are common enough, but none had such character as this one.
@TechConnectify I'm trying to remember if if beeped as well. I think so? @womump do you remember?
WOMUMP@xanna @TechConnectify Certainly I remember a "*boo-beep* Attention! Securicor vehicle ... reversing!"
Tony Wells@womump @xanna @TechConnectify
The talking ones in the UK I've heard say "STAND WELL CLEAR, VEHICLE REVERSING" between the beeps.
I would like a programmable one. The Waitrose van would definitely say "I say old chap, this vehicle... it's... reversing! The Evri/Hermes courier van would say "GET OUT OF THE WAY, I'M LATE" while launching random parcels into gardens.
@TechConnectify super fun video. Your scripts always make me smile no matter the subject 😁 Thank you for the jokes.
Jeff Higgins@TechConnectify I've been noticing the change to white noise here in Toronto for many years now, it seems any project that has any government involvement uses them exclusively, outside of that though still plenty of beeping.
Regardless the change is very welcome here in a large city.
bedast@TechConnectify The one fault I’ll give Kia/Hyundai (at least in the Niro EV) is they put the VESS in the front of the car. With the updated module from the E-GMP stuff, it’s much quieter than first gen Niro/Kona EV so it’s easy for the sound to get lost.
I’ve considered seeing if I can relocate it to the rear of the car. Might have to be creative with the wiring.

@TechConnectify was wondering if you'd ever do a video on this. One thing though, unfortunately the white noise reverse alarms aren't actually a legal requirement in the UK yet, just certain construction sites and maybe some local bylaws require them. I wish they were though, they are so much less obnoxious than the beeping ones.

Canada rolls out a universal car horn language
This week the Canadian Automobile Regulatory Commission rolled out a new system to communicate on our roads and highways that employs an intricate system of horn honks. All Canadians will have to learn the language of 54 honks by next spring. This Is That's Pat Kelly interviewed the head of the Commission to learn more.
@TechConnectify do the cars with anemic reversing lights have reversing cameras with low-light modes fitted as standard? Are they maybe deliberately not illuminating too much so they don't suddenly switch to daylight mode or whatever and actually do a worse job?
I have indeed reversed on a dark country road with huge ditches on either side of me before, using only the glow of the reversing lights, as nature intended - but I would have swapped them for a good video feed in a heartbeat.

@TechConnectify uhm... Wouldn't splicing the reverse lamp on modern cars somehow mess up with the sensed load, leading to the ECU believing a lamp is either burnt while still functioning (thus triggering an alert on the dashboard), and/or vice versa?
RetroSwim@TechConnectify I can't help but feel that in addition do the direction-detect-ability, the screechy white noise is nice and distinct from any number of other devices in outdoor environments that emit monospaced square wave beeps to advertise their presence. Even if we could pick the origin of a reverse beeper, it could just be a gate closing, or a scissor lift raising, and we might tend to ignore it.
yomimono, still on land@TechConnectify I had to immediately look up your shirt, so this was very effective Raton Pass Awareness Month content
@TechConnectify also, thank you for tricking my cat into thinking a car was reversing nearby
@TechConnectify
Love your channel TC!
If you can get your hands on the upcoming tech using Low-Energy Nuclear Reactions (LENR), please do a video on that!!!
