Fixing the Sundia Diabolo LED kit

Both fully working

A while ago I blogged about trying to replace the battery on the Sundia Diabolo LED kit.

Lots of friends tweeted me and helped.

I learned a lot including LiPo is always 3.7v and the configuration of the numbers which were faded out on the current battery. With that information I finally bought some batteries from ebay.

They took a while to come but I did a few rough tests and it seemed to work and then not work. So I left it, however I now know the reason why it was on and off is because of the wiring.

Black tape to fix the LED kit

The wiring was small and trying to bind the wires with my large hands was always going to be a problem. In the end I finally got it hooked up and stripped the wires back further than originally planned. Once done, it was stable and I was able to make it work consistently.

What it really needs is soldering because lets be honest its going to be thrown around a lot and the impact on my black tapped connections will be high. Because of this, I’m considering adding foam or bubble wrap to the inside of the case to put less pressure on the inner elements. Ultimately they should be soldered and the battery stuck in place with something stronger than black tape.

Ironically I decided to get a fire diabolo, at long last. There is something about Fire which is much more impressive but infinitely more dangerous (in a good and bad way).

Update on the Sundia Diabolo LED

Jasmine's magic touch on the Sundia LED kit

With the mess which kind of worked, I thought I need to talk to a professional about it. My good friend Jasmine was the natural choice, so with chocolate, a takeaway and some good conversation. Jasmine lent her professional eyes to the LED kit. Fixing everything so well, I was blown away with the results as you can see above!

Now thats how to fix the Sundia Diabolo LED kit!

Help in seeking the Sundia LED kit battery

Daylight is drawing in earlier and earlier every day and because of that, lights are extremely useful when using the Diabolo during dusk. Not only that, it looks frankly amazing. It also means the monthly Firejam in Castlefield bowl has started up again.

Dusting off my LEDs and adding them to the Diabolo again. However there is a problem. I am pretty much in love with Sundia Diabolos and the battery in my Sundia LED kit is pretty much dead. Can I get another one? Not a chance, its sold out everywhere it seems.

Sundia Diabolo LED kit uncovered

After unscrewing the LED kit, I noticed a small rechargeable battery like the Pacemaker one. Currently it all works when plugged into MiniUSB (bottom left), which clearly suggests the battery isn’t holding any power anymore. So I  decided to look into getting a replacement battery because its worked so well for my Pacemaker device and I’m about to do similar for my pebble smart watches.

However I can not find the battery type or anything about it. I assume its a 3.7V tiny lipo Li Polymer rechargeable battery with a connector but I can’t confirm this at all. Both sides of the battery have no details except a slightly faded Sundia wording. I also don’t see anything on the circuit board but I’m sure someone reading knows or can help me.

The circuit board details

I think this might do the job but anyone who can point me would be massively useful.

Metaverse

We live in incredible times with such possibilities that is clear. Although its easily dismissed seeing the lack of coverage for facebook whistleblower sophie zhang, thinking about those batteries and yet another data breach.

To quote Buckminster Fuller “You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete.”

You are seeing aspects of this with seeing twitter crop bias bug bounty, the discussion about removing the landline and the social dilemma free on youtube for a month.

Tech Crunch gets on the moving train

Ian thinks: Reading this, I can’t really take Techcrunch seriously, because for every one of these startups focused on privacy and security. Theres at least 20 more startups covered the opposite. Maybe its just me?

Envisioning the future of social media

Ian thinks: This interview with Ethan Zuckerman is full of some great points to get you thinking, I find it hard to disagree with Ethan especially around using affordances and setting up small town based on Mastodon.

Values not eyeballs please

Ian thinks: Its always interesting to hear from experts in the space, on the work you are involved in. Its a really good read especially if you haven’t come across the Human Values, which also has new podcast interviews.

Apple cares about your privacy?

Ian thinks: I do find it so ironic, Apple making a song a dance about their privacy changes but their own browser Safari, not including any strong level of privacy? Of course Apple are in privacy hot water for much more too.

What is really behind Only Fans new policy? and its Uturn?

Ian thinks: There is a important question about the platform and who has influence over the platform. As this twitter thread says, you really need to think about the platform & infrastructure,

The dystopia which is the metaverse

Ian thinks: There is so much talk about the metaverse but few looking at the privacy, security, infrastructure and trust within this space. Till then I can’t help but think Vice is kind of right.

Its started with a MP3 player

Ian thinks: Dan Hon’s rant starts with a want and spans the internet media ecosystem, pointing out so many of the problems we all know too well.

Blackhat & Defcon happened, here’s the scary flaws

Ian thinks: I always love seeing what comes out of these security events. You can also watch the full videos from Blackhat and Defcon online here.

Ian thinks:The webmon showcase is a nice summary of some of the projects which came out of the Grant for the web initiative

Mozilla thumbs down Facebooks claims about Ad Observer

Ian thinks: Its so interesting to see Facebook’s concerns around Ad observer squashed in one post by the privacy first Mozilla. This is deeply concerning behavior, what is Facebook worried about?

Why NHS’s world-beating app was always a going to be awful but 10+ million!

Contact tracing api

Even if you forget the thoughts are coming from a ex-googler who has interests elsewhere this blog is pretty damming and I  can imagine how the NHS really bought their own nonsense about it being world beating. Of course in the end they had to back pedal and use the Google & Apple decentralised contact tracing api.

But there are parts even I was shocked at…

It worked 4% of the time.

Thats not even funny, its not just unreliable but a total waste of time. Even if thats exaggerated, double would still be a bad joke at 8%

The British effort did find workarounds that most other developers could not: They used “keepalives” (messages sent by one device to another) to circumvent restrictions on having apps in the background on iOS. Notifications were sent between two Apple devices running the app to keep the connection between the devices alive and therefore having the ability to detect each other’s keys. The NHS tried to develop with a hacker’s mentality and shared its progress through its GitHub page.

There is a reason why keepalives are a bad idea, battery is one of the number one reasons why people find their smartphones deeply frustrating. Having a app keeping the system awake is just a terrible news. Although I assume as most people are staying at home, they will be closer to a charger at least

in May it was reported by the Financial Times that the British government was simultaneously exploring a solution with Apple and Google’s decentralized system as a backup, indicating that, even within the government, there were doubts that the centralized effort could work.

And this is when I heard they were testing both systems, leading to the fact they were going to drop the centralised app soon. This would be fine but…

The development of the app has taken months and cost millions of pounds from taxpayers…

…around $15 million spent…

I have no words to sum how I feel about the UK government throwing this money down the drain in the middle of a pandemic where people are losing their jobs and dying. Its not just wasteful, its incredibly disgraceful and pretty much sums up the UK government right now.

Is the pixel 4 worth it?

My Google Pixel 4 battery stats

I was reading through my feed and saw this review of the Pixel4 4 moths later.If I was to write a review of the Pixel 4 months later, I would have some choice words to say. Many more than what I originally wrote.
BatteryThe Pixel 4 battery is weird. For example I’m on 43% and it will last till 9:30am tomorrow morning. However a few weeks ago I looked at my phone and noticed it was on 5% and I have no understanding why?
Generally I only charge it when I’m sleeping, but its only been 4-5 months. I think it might be one of the only phones I might need to replace the battery of in 18 months.There is hope of a ultra low power mode, which if its like Doze could be a game changer.SoliI have to echo the reviewer, as its sums it up and I turned it off except when using the Face ID.

For several years, Google has been working on Project Soli: a radar-based sensor system allowing a device to sense gestures with utmost precision. Fancy videos of the system in action show how virtual dials and buttons can be controlled effortlessly by the snap or flick of a finger. No touching the phone required.

The Pixel 4 and 4 XL are the first two phones to ship with Google’s radar-based system – and it’s bad on so many levels. First of all, its use is extremely limited. With a wave over the screen you can skip songs, mute alarms, or play with your Pokemon live wallpaper. That’s it, really.

To make things worst I turned off active edge and other sensing things as its just not important for me. Weirdly enough every few times I pick up my Pixel4 it vibrates.

Is it worth it?

Well its a good phone but a lot of the features have made it down to the Pixel 2. The Cameras are great but should I have waited for the Pixel 5 or 4A? I do feel I maybe should have replaced the battery on my Pixel 2 and maybe waited…

And where the **** is my Chromebook, Google?!pixeloffer chromebook statusI’m pretty annoyed about the Pixel4 chromebook offer. It was meant to come a little later after buying the Pixel4 but its been 4-5 months!

The Google Pixel 4 battery needs some help

89% battery on my Pixel4

There is a lot of discussion about the lack of battery for the Google Pixel 4. To be fair its been pretty good to me, but its certainly not the same type of battery life of my pixel2 or nokia8 which lasted a few days at ease.

More details about the battery use
Fedilab what the?

The picture above is with Wifi, Bluetooth (with my pebble, motiv ring attached), NFC,  KDEconnect, dark mode and most of the apps I run daily.

To be fair I don’t use the screen much, relying on my pebble watch, KDEconnect for some interactions.

34% battery on my Pixel4

After a day of usage, I end up with 34% but it claims to last till 8:15 if I decided to keep it going, however I think that would drop massively with my sleep tracking.

Its all workable right now but I do hope they will drop the high refresh rate in favor of better battery life? Its super slick but I was happy with my Pixel2, so I’m not so bothered about higher refresh rates.

As I talk about the Pixel4… here’s a few things which I have done.

I turned off the radar ambient stuff because I found it annoying, so it won’t do the face unlock till I press the power button on the side. As usual I turn off the ambient display because like notification lights/sounds its annoying. The Face unlock is stupidly fast and its worked in almost every single scenario including a pitch black room with no lights. I do find the no eyes quite scary as I do take security pretty seriously and find Google’s lockdown not the most workable thing but its a stopgap. I do wish there was a fingerprint option or something to fill the void between the two, as typing in passwords each time is quite painful, especially when I have some stupid length passwords.

Expect more about the Pixel4 soon…

 

Pacemaker big battery replacement

Old Pacemaker with new 1500mAh battery

Thanks to our excellent lab technician Elizabeth. I bought a 3.7v battery to replace the one in my 2nd pacemaker. I previously had replaced the 1.8 inch SSD with a SD card, so knew there was more room in the pacemaker case.

I had hoped to buy a very thin battery which I could slip under the SD card but I couldn’t find one with a higher capacity than 500mAh. Instead I looked for the highest capacity I could get which fit into the same battery space. I found a few 1100mAh batteries but then finally found one which was 1500mAh and the same voltage.

I unfortunately couldn’t didn’t quite get the right size, I was about 1-2mm’s off in height. The only way to make it fit was to remove the brackets which protected the old SSD/HD from the battery. As there was no drive anymore I decided its ok to remove them. With them gone, I could shift the battery over a bit and fit it in.

With some great soldering from Elizabeth, I was able to get everything back in the case and screw the whole thing together.

Looking forward to doing similar with my main pacemaker device, maybe?

Pacemaker device finally upgraded with a SD card

IMG_20190819_192629

This time while upgrading the Pacemaker device it was a success. Its a strange combination because I got a Micro SD stuck in a SD card which is stuck in a Compact Flash card which is connected to the Pacemaker device with a tight Zif cable.

Its not so tight as when I had the 1.8inch SSD but the zif cable is still not in the best position it could be if it was shorter, as I noted on my original pacemaker device.

Next stop is to upgrade that battery. I’m thinking about a larger flat battery which can lay on top of the compact flash holder?

iPhone XR ad promotes smartphone addiction as a way of life?

Found via Hannah while working away, Latest iPhone XR ad promotes smartphone addiction as a way of life, and that’s bad
I hadn’t seen these Apple adverts but yes this isn’t good and strange for a company who was pushing for time well spent a while ago.

If you are affected by any of this, I would recommend having a look at my guide to take control of your smartphone and likely improve your phone and personal batteries

My nexus 5x battery is pleasingly decent

I got to say this isn’t bad going for my nexus 5x with 4g, WiFi, Bluetooth and NFC on all the time. I was using my Bluetooth headphones at work for music and calls. Plus I got my pebble smartwatch on all the time.

I was pleased to see so much power without turning anything off or doing anything special to save power.
