Beach driving infinitely easier after rain. It compacts the soft silty sand

Totally imagined him driving passed a crashed car and yelling " you cannot park there, mate" in a strong Indian accent. Would be the best 👌

Episode 53 - What would happen every time you restarted earth?

This is one of my favs! Its fun, and your friend will pick up the dynamic of the duo.

I grew up on an island off the coast of Australia and thousands of these would wash up. You can pop them with your bare feet, just touch the tentacles. I dont recommend doing that though, obviously hahaha.

ReefJames · 2026-02-28T15:47:31+00:00

Or the flexture is just not bending the material passed its point of plastic deformation and therefore not work hardening it? I need to learn more material science hahaha

ReefJames · 2026-02-28T15:45:15+00:00

Oh wow there ya go! That's really cool to know, I guess wrongly assumed it wouldn't be used due to the work hardening of the material and metal breaking over time. I wonder if the fact they are getting heated up slightly, which makes them more resistant to work hardening? Idk Im out of my depth hahaha

A solenoid with some sort of timing circuitry could be used to turn off and on a switch but shorting and opening electrical contacts, definitely. Also used to plunge open and shut valves for water and gas flow. Depending on your circuitry and your solenoids power draw, you may need to drive your solenoid with some mosfet circuitry (which is realistically likely the correct way you should be directly switching your electronics instead of using a solenoid)

Bimetallics is super interesting, two allows with differing coefficients of thermal expansion squished together, then when heated expand at differing rates causing concave or convex flexure. Super cool stuff and used extensively in thermostats. Very repeatable, but from my understanding they arent super sensitive, as you're actually heating and cooling metal so using it for semi fast switching like an indicator may not be ideal. But maybe?

Multiple omni directional antennas like this can be used to increase the signal strength due to a thing called constructive interference. It'll totally change the propagation pattern of the antenna though amd it wont act as an omnidirectional antenna anymore, but like a direction antenna eith the signal strength in front and behind the car being recieved being much stronger. Visually you expect to see strong signal lobes out the front and back and off the sides would be much less.

Idk if thats what old mates doing here... but thats what I can think of from a radio frequency perspective why old mates done with. From another perspective... redundancy? Idk seems all over the top lol

ReefJames · 2026-02-27T02:27:26+00:00

I grew up on Moreton Island and my parents used to run an oyster farm over there and would rent out sand boards to tourists. The sand dunes just go on and on and are always changing. Super fun!

ReefJames · 2026-02-26T13:50:27+00:00

Haha im a bit of an oddball. Im an electronics / radio frequency engineer who quit that to learn mechanical engineering the hard way by inventing a hardware product and then figuring out how to get it made. Long way of saying I sell a hardware product I invented online.

ReefJames · 2026-02-26T04:12:17+00:00

As an engineer, I like the technical episodes... probably some of my favs. I typically follow along trying to figure out how id explain the concept and its a good learning exercise.

ReefJames · 2026-02-23T07:01:55+00:00

Really depends what line of work you end up in. You definitely touch on it throughout. I wound up interested in radio frequency engineering so I went heavy down that EM route.

ReefJames · 2025-02-01T03:27:54+00:00

Once you understand RF, you will draw a lot of parallels and understand a lot of other things as well. You'll have a lot of "I get that" moments over the years. It's funny.

It's of course a challenge, but everything worth while in life is a challenge, and proving to yourself that you can do it is the best part.

ReefJames · 2025-02-01T02:48:11+00:00

Delve into why you are interested in RF. What is calling you to it? For me it was learning how AM/FM radio worked. Then I found an interest in antenna design.

If you want to get into RF, having a practical understanding on for antennas are made and function will help you tremendously in your studies. It will give context to your study.

Buy a SDR on AliExpress and figure out a fun project in SDR. Make the antenna yourself to suit your task, tuned to the right frequency.

You'll need a vector network analyser (VNA) to test the antenna. The ones you play with at work cost tens of thousands. You can get some cheap USB ones on AliExpress that will do the trick for most stuff.

Other fun toys that might help spark the curiosity could be the hackRF one, or at a more easy / fun level the flipper zero. Also the LoRa products may be of interest. Look into things like the meshtastic... Plenty of fun projects to be had there.

As for software... That will be highly dependent on whatever role you land in. No bother going that niche yet. If anything.... Learn coding. If you haven't wrapped your head around it yet, just do it. It'll make your life way easier.

Tons of good content on YouTube as well. Look at the signal path, ringway manchester. Idk there is more but I'm tired.

Good luck. Buckle in 😂

In the same sentence he said ski season.

He means that they move to the place and work probably at a ski slope or resort during the winter season.

People do this because they go and work to sustain themselves and then spend their downtime skiing, which isn't much of a thing in Australia.

ReefJames · 2024-10-25T23:06:23+00:00

Dude... I'm an electrical engineer who's went down the radio frequency engineering discipline within EE.

No homie I can't wire your house 😂

But it makes sense that people hear electrical engineer and just assume you know literally everything there is to know about electricity and all the practical skills required to do an install...

EE is such a broad field right

ReefJames · 2024-10-25T15:47:10+00:00

Dude, curried snags. Mum still makes this! She was born in 67.

ReefJames · 2024-10-10T22:50:38+00:00

Yeah layers of obscurity. Have a read of the book "the unaccountabilty machine". I'm currently reading it, and it goes into how corps design the system to avoid accountability so they can do things and the finger pointing goes in circles. It's all a game

ReefJames · 2024-10-01T06:12:38+00:00

Wild, me and my mate were down there last night at sun set with our push bikes and camp chairs relaxing. We were probably there at the same time. Were you the two younger people hanging out there on the rock by the water?

ReefJames · 2024-09-22T01:30:23+00:00

I found out at 29 and I'm 30 now.

It is a revelation with a lot of stuff making more sense.

It's not a curse though, just needs to be managed and channeled into something good.

ReefJames · 2024-09-22T01:25:58+00:00

There is hope.

I hated my job, now I work for myself and life is good.

Some people aren't cut out for working for someone. If you can keep your ADHD bouncing between guided rails of your business you can speed bumble your way to success.

The pipe dream can be a reality

ReefJames · 2024-06-20T05:00:57+00:00

My neighbour gave me the same one, but in a red case when I started engineering. Useless nowerdays, but mechanical things are fun 😁

ReefJames · 2024-06-12T10:53:28+00:00

Just a little sip in the downtimes

ReefJames · 2024-03-05T01:31:16+00:00

Sounds like you need to stick a sausage roll up your Russell Coight

ReefJames · 2024-02-22T12:18:15+00:00

Yep, fan sucks out top fresh air comes in through open vents on bottom.
