Minidisc, a throwback to the future

I think the world is again ready for the Minidisc, and here’s why I think that.

Ok, so I’m an enthusiast, but you should be too, after all, you (Sony) invented the format.

Few people now have a personal music player aside from their cell phones. While some cell phones are excellent (few and far between), most are pants when it comes to music reproduction, virtually all have poor battery lives compared to a 15 year old Minidisc player’s 45 hours continuous use! Try that on an iPhone

I’ve an old (obviously) NetMD NH-1600, and with a HI-MD  1GB disk and the lowest compression possible, it sounds nothing short of staggering, even today. Plus there’s up to what, 43 albums on one disc(k). Personally I prefer quality over quantity, and so do many other people. So I’m sure today Sony could manage 5GB, 10GB or even up to…. dare I say, 20GB on one disc. With modern technology, I’m sure it’s more than possible, and the battery life could probably be stretched further too.

I also think that reading and writing could be faster with improved latency for the ATRAC chip, improved TOC reading and writing. These were the Achilles heel back then.

Then of course there’s the improvements in fidelity today. Lower compression but with less space, higher capacity disks, much better head-gear, longer lasting batteries, better reliability, and now of course, transferring via PC at high speed, and with song titles and all that lovely data that was frustrating to get on the track.

There is a very very vibrant market for the old Minidisc on ebay, gumtree and craigs list worldwide. That being the case, I do think there is a market to be tapped into. People young and old need a PMP that isn’t a phone and doesn’t suck.

Please please take a look at what is going on in the used market, see for yourself the prices of discs and players, they’re astronomical and they’re only going one way… UP!

Thank you for reading this letter.

I’ve sold my bike :(

On Monday I sold my Crossfire-E. It’s been a fantastic 2 and a half years. But the time came to part ways.

The guy who bought it is called Daren and he lives in Birmingham, so for him it was a 5 hour round trip.

I sold it for £500 with ALL my gear, all the extras, and even the spare battery. A bargain at that price. Nearly £2000 worth of kit. I could have sold it for £700 and even that’s a bargain, but it would have meant waiting for the right buyer for a week or so, and in that time I no doubt would have changed my mind and taken the advert down.

 

The reason I sold it is simple, I didn’t have time anymore to ride it. So it sat there unused. Taking up space, and it takes up a lot of space. It was a 21 inch frame and 700c wheels. It is a HUGE bike. I am also a fair weather biker, and the weather was lousy.

So sadly we part ways.

I just hope the new owner can love it as much as I do.

 

Raspberry Pi 4 or 3 or 2 or 1 temperature monitor via HTTP

OMG the raspberry pi 4 gets hot, and that’s even with the new “cooler” firmware. At idle I’m measuring a temperature of 55°C. Im now quite glad I installed the monitor so I can keep an eye on it as its randomly crashed quite a few times.

So the install source is: https://xavierberger.github.io/RPi-Monitor-docs/11_installation.html

sudo apt-get install dirmngr
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 2C0D3C0F
sudo wget http://goo.gl/vewCLL -O /etc/apt/sources.list.d/rpimonitor.list
sudo apt-get update
sudo apt-get install rpimonitor

http://raspberrypi.local:8888/

my address is http://Daz-Pi-4.local:8888 yours might be different depending on your settings. Or just use the IP address:8888

E-Bike Battery Cell Replacement

 

It’s better than buying a complete new pack. Why? Because there’s a guy out there who will replace the individual cells. I’ve been quoted a price of £140 or a possible upgrade of £170 depending on how many cells and their configuration (series and parallel).

So i think what you have there is 10s4p battery pack or 10s5p
I will be able to make it like new 10s4p (13.6AH ) for 140GBP

Alternatively

or if it is 10s5p battery pack I can fit in 17AH ( 170 GBP )
( i will use Panasonic NCR_B ) cells
and each of my batteries will have a 2 year guarantee 🙂

And there’s also a bluetooth upgrade for £25, this will connect to your phone and it will give you precise data about the individual cells and the battery pack.

I can’t speak for other battery packs, but I know the packs from Halfords for their bikes start at £400 for a brand new pack.

So now my old pack, 3 years old, is getting a little past it, I’m really tempted to go for it, I’m just a little skint right now and I can’t afford it, at least not this month.

Just let Mat know The Bionic Cyclist sent you 🙂

Mat has also made me aware of the the other things he does:

Hi i can recell/Repair all type of batteries but i’m not doing flat type of batteries ( rear battery packs)( flat one ) or small bottle batteries ( which have 3x levels of cells )
also i have ready to use battery packs in blue thermo wrap ( with LCD /or Smart BMS ) 36V
+ I can make custom size ( Triangle/Rectangle battery pack ) 36V-72V (up to 3000W/5000W and more )
+ 36V custom battery for full suspension frame bikes
+ Just welded packs DIY (without BMS )
+ 24V – 48V Battery packs for Powerwalls / Campers / Chargers 1.5Kwh/2Kwh/3Kwh
+ 18650 cells for Sal

So that’s quite a range of different things in all.

GoPro Fusion Review

I’ve made a post on the forum and it’s not pretty, I like the hardware, it’s excellent. Unfortunately the software is a disaster. The camera has been available for over 2 years now, and gopro has done nothing to improve the situation, and they’re preparing a new 360 camera for launch. Unless they launch a new app for editing 360 videos that’s as good as the Insta360 One X app, then I can see this being a disaster for Gopro, and rumour is that they’re struggling to stay afloat.

https://the-bionic-cyclist.co.uk/forum/viewtopic.php?f=4&t=53

 

This video shows how easy is is to use the Insta350 Studio to edit and reframe a 360 video. Sadly the Fusion requires three different types of software to acheive the same thing.

1. Gopro Fusion Studio to stitch the 2 cameras together (even on my beast AMD Ryzen 2700x, 16GB RAM and all SSD drives it takes hours and hours and hours just to stitch them.

2. Corel Paintsop Pro 2019 for Tiny Planet photos. £55

3. Adobe Premier for the video, keyframing and reframing the views. £20 per month for as long as you’ll use it.

The insta360 Studio does all this in the app that comes with the camera and for free.

New to the site – A Forum!

I’ve thought about this for a while, on and off, and today I decided to jump in and do it.

It’s a lot of work, luckily I’m a bit of a Pro when it comes to PHPbb3, I’ve used it for years as the founder Admin on sites around the web, and helped others setup PHPbb too. So this part is easy, though it’s time consuming.

I’d really love for everyone to join in and help me make a community, based on and around cycling, Ebikes, and well, anything you like (within reason). I’ve added a few off-topics, like Movies and TV shows, but of there’s something you’d like to see, then just register and post a suggestion.

Carrera Crossfuse Ebike review

New to this website, a forum!

This is not my review, but it comes from someone I respect, if only because of the miles he rides… in 18 months he managed 4,500 miles on the Crossfire-E. Now he has a Crossfuse and by the sound of it, he loves it more than the Crossfire. With no cut-outs that plague the Crossfire-E, though these can be reduced dramatically on the Crossfire-E, it’s not an issue at all on the Crossfuse, and with now several thousand miles on the Crossfuse, Drewpyfz6 definitely enjoys electric cycling.

One day… one day I’ll get to ride this bike and I’ll be able to give it my review.

This next video shows how you can overide the speed limit of 15mph and increase it to 20mph (this is naughty but it’s only 5mph so no big deal). This is the same person, Drewpyfz6 and one of his commute videos.

Climate Change Allan Savory

Desertification is a fancy word for land that is turning to desert,” begins Allan Savory in this quietly powerful talk. And terrifyingly, it’s happening to about two-thirds of the world’s grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos. Savory has devoted his life to stopping it. He now believes — and his work so far shows — that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.

 

I’ve watched this video several times because it’s fascinating. Can we really put a stop to climate change simply by bringing cattle back to deserts? On the one had it makes perfect sense, cattle produce copious amounts of manure and nitrates. Plants love these, in fact, plants cannot survive without them, so plants will thrive. But you still need water. Fertiliser isn’t enough on it’s own, so you’d need to plan the grazing a few months before the wet season to maximise growth.
