Late Easter

Hello everyone, a belated Happy Easter to you all. Gosh it’s been a while again. I have had a few ideas simmering on the brain for a post but the “New Post” button wasn’t getting pressed to initiate them … However, one thing I did manage to do was break the sketch block that had been going for about 18 months …

Picture. A rough sketch of a dwagon. He's standing with his feet pointing to his right (our left) in black strokes intended to be shoes. His right paw is raised above his head, his left paw is on his hip. He is winking his left eye.
Friday? Night Fever ?

I probably gave away the muse but hopefully you recognise the pose from the movie. The inspiration was Knightenator, who I just recently started watching on Twitch (link) after she was raided again by the ever lovely Tashnarr (link). Raiding is where a stream takes their viewers over to another streamer when the time comes to shut down their stream and it’s fantastic for discoverability of streamers similar to who you were watching. It gives you an immediate suggestion for “If you like me then you should like this person too who is continuing after I go offline”.

Hmm. This could be a randomised post. I can see it coming :-). Knight was on earlier playing more multiplayer Apex Legends (not something I play but she makes it curious to watch) and is another one who indulges in the Truck Game, European Truck Simulator 2. I’ve been enjoying that game a lot although I think I might take a break from it for a bit because they’ve tweaked the AI and made them pretty dangerous (which has been annoying me).

So … what have I been up to ? The post ideas in my head are things like : Truck Game and how it relates to modern day logistics. You know, things like when you click the button to order something online, what’s involved in getting it to your door. Or to the shop you get the thing from. That’ll be for a later post I think. I think I’m due a music post at some point too. I was in Cardiff on Wednesday and picked up some more cd’s, 3 from Morcheeba, 1 from Enya, a Nerina Pallot cd and something speculative from Beverley Craven. Haven’t listened to them yet, I’ll weave the new tracks in between the other music I listen to and gradually figure out what I think of them like that. And then I’ll weave in the whole album along the way too.

I had this week off work, which has allowed for :

A bit too much Truck Game time;

Indulging in Skyrim again. I have a heavily modded playthrough going …

Game screenshot. Skyrim. We're looking at the back of our heroine. She's wearing heavy iron armour and is on a ledge looking down at a valley filled with thin tall trees.
A snowy view

It still looks good, it’s an easy game to play and the ease of modding it enhances it even more. That’s a curious one though, it’s an easy one to lose yourself in because they’ve buried stuff to find everywhere and the gameplay style I prefer of a big sword and heavy armour means I’m not having to think too much about hitting things.

The Motorsport Manager campaign continues and still provides interesting racing. As in, the team is winning races now but I’m having to work hard to get the wins or we’re getting advantage from being able to handle changeable weather better than the AI.

And a trip to Cardiff happened on Wednesday.

Picture. We're looking over a balcony with a golden railing at a clock in a steeple. It's in a wooden building above a row of market stalls underneath. There are more shops on a far balcony over to the other side.
Lunch with a different view

That’s the indoor market area in Cardiff and I discovered a bacon sandwich shop and a cd shop next door to it. One pondering after though is, places like the cd shop and the book shop don’t seem to change their offerings too much … I haven’t registered too much change to that Picture Of How Things Are in the book shop lately. How often do they get new stuff in ? A curiosity …

I’m mostly going to wrap up there though but one thing I did want to think out loud on was remote control cars again. I didn’t get one on Wednesday because homing instinct was kicking in (apparently I tweaked my knee again and couldn’t feel the pain from it yet) and I don’t like to make money decisions when my head’s not right. When I do get one, I want to make sure I get all the right things … What’s needed ?

Picture. We're looking at a remote control car. It has two thing wheels at the front and we see one (of two) wheels at the back, with a spiked rubber tyre. The shell is white plastic with stickers above a black plastic tub.
Ah ! Grasshopper

So – things you need include : The Car ! Batteries. These come in packs of 6 in a moulded casing. It takes about 15 minutes to fast charge (which you don’t want to do too much due to damage) and they give about 15 minutes run time. So you want two battery packs. You want AA batteries for the receiver and transmitter. The remote control part is a 2.4GHz pair. You need a motor, a speed controller and a servo for the steering. Oh and you probably want a toolkit if what you have isn’t up to what you want.

One thing I’m confused about is what’s actually in the box … The couple I have my eye on are the racing car style Porsche 911 kit (link) and the more buggy style 4 wheel drive Thunder Dragon (link). Yep. Dragon pulled it out of the pack. They’re both Tamiya kits. You can get “Ready to Race” kits as well which are fully assembled but I’d want to put it together so I can understand how all of the parts work together.

Both kits take the standard 7.2V battery module, both have a motor (RS540 is a standard size for pretty much all electric remote control cars) but whereas the buggy has a speed controller, the Porsche kit doesn’t.

Antics supply a collected kit for most of the bits : Carson 2.4GHz radio and receiver. That’s got the transmitter and receiver pair, a battery pack for the car, AA batteries, a servo that does the steering and a trickle charger for the battery pack. The Porsche would need a speed controller as well. Which might mean a different type of motor as well … Choices :-D.

Motors ? There’s lots of different types that run on different types of power. The ones that go in your vacuum cleaner or mower will be Alternating Current (AC) Induction motors. They rely on the waveform of mains power to work. It’s a wiggly (sine wave) waveform and the motor rotor (the bit that spins) basically follows the electromagnetic field in the stator (the shell) windings that have the power. These motors just keep going because there are very few contact points outside of the bearings that hold the rotor where it should be.

Direct Current (DC) motors that run off batteries can’t do that. Instead of the power waveform being wiggly, it’s a straight line of constant voltage. A brushed motor has contact points that connect the electricity to the spinning part. As the motor spins, the connection swaps over and the motor keeps turning. However, the brushes wear out over time and need to be cleaned and ultimately replaced to keep the motor working. Brushless motors are kind of a mix between DC motors and AC Induction motors, they rely on a speed controller to turn the power on and off at specific points in the rotation of the motor. (Is too complex to describe here but was probably inspired by how 4 stroke combustion engines work)

The speed controllers work by chopping up the power going to the motor. If the power is only turned on for 10% of the cycle, the car being driven by the motor goes slower. The brushless speed controllers apply the power so that the rotor follows the electromagnetic field.

Oops. Digression and nerdiness happened … Bits list ! I did say I’d be thinking aloud … If I was to go for the Porsche, the bill from Antics would be :

The car – £129.

Carson Reflex pro radio kit, 7.2V battery, charger, servo – £80

Etronix ET0103 electronic speed controller – £20

(A brushless motor and controller starts around £80)

Extra 7.2V 5300mAh battery – £35

Fast charger Perkins GTP0166 – £28

Mini toolkit for £20.

So … that all works out to £312 to get in to the hobby and that’s going cheap on a few items. One thing I have already is the boost starter for the car. That has a 12V car battery in it that can also do 240V mains power so it can feed the charger.

It’s a fair bit to get in there isn’t it ? One thing I’m very conscious of is there’s a big gap between what I currently know and what the magazines assume that you know. And the only way to bridge that gap is by diving in. Although i have just looked at the Ready to Go cars and there’s a buggy car for £125 which includes the radio kit. Maybe it’s all what you pay for again, like that extra battery is 4 times the capacity of the one in the £125 kit.

We’ll see. I think that’s enough thinking aloud for now. Book time ! I enjoyed reading Light Chaser by Gareth L Powell and Peter F Hamilton. A bit short again maybe but there’s a lot to be said for a story that gets in, tells its thing and gets out again fast instead of indulging in repetition of what you already read or having a promising beginning that dribbles out into a tame end. Worth the cash and well worth a read.

Good night everyone, I must post more !
