My Harman Kardon headphones and my sausage fingers don't go well sometimes - occasionally when switching off the ANC I accidentally put the headphones into pairing mode.

When this happens, a massive popup with a picture of my headphones appears on my phone screen, prompting me to connect via bluetooth, a bit like that iOS one that shows up when you hold your earpod case near the device.

Anyone aware what this popup feature is called? I'd like to ultimately switch it off - don't really like the idea of nearby bluetooth devices opening massive popups on my device, just because they're in pairing mode

I woke up this morning to an awful looking homescreen on my Android - turns out my Niagara Launcher subscription had lapsed!

I went to check the renewal prices, and they were literally 2-3x more expensive than what I was paying recently - not really excited about that.

Since my homescreen already looked like garbage, I decided may as well try Kvaesitso, a FOSS search-based launcher. I tried it in the past, but abandoned it since I would want to set up my homescreen and apply an icon pack to all the apps individually.

After several hours of setup (mainly applying the icon pack 😭), I've been using it throughout the rest of the day and I'm pretty pleased with it, it's a very smooth, polished and well thought out minimal search-focused launcher. Here's what I like and don't like so far:

Like

• Search is much more powerful: can use DuckDuckGo or any custom search engine, search app shortcuts (i.e. webpages saved as apps), as well as tagging apps - none of these are possible in Niagara
• Very, very customizable
• Supports gestures to open apps or run things, so even less apps are needed on my homescreen
• The clock looks so nice
• Cool charging animation that shows rising bubbles from the bottom of the homescreen
• Contextual media controls under the clock
• Allows full-size widgets on the homescreen, these can be hidden off-screen by default if you prefer

Meh but not dealbreakers

• Upcoming calendar events don't show up under the clock, however there is a very nice custom calendar widget included
• Contextual media app cannot be set (e.g. when bluetooth/3.5mm headphone is connected, pin music app on homescreen)

Highly recommend giving it a try if your Niagara subscription lapses, and open to trying a neat FOSS alternative!

This decade old electric cooler box gave up the ghost around 2 years ago, with the indoor outlet plug no longer working. The independent 12v input was still operational, so I kept it with the intention of eventually fixing it...

And two years later, this is the eventually 😅. The integrated 10v ~45w unit had failed short on the primary side, with a burnt out Y-capacitor and some fried zeners. I started removing bits from the board to try and find all the broken components... but ended up letting out the magic smoke in the process, oops!

I set out looking for a new power supply, and came across a 12v 45w unit from Meanwell. It was actually smaller than the cooler's original power supply too, meaning more internal space to use later 🤫

After searching for a distributor that was actually willing to ship it to a home address, I ordered, and boom:

It's so tiny compared to the original.

Next I installed an Arduino Nano to control the TEC/peltier module & fan via a cheap LED repeater. I was hoping to reuse the internal temperature sensors, but left them disconnected for now

After hours writing the arduino code, I finally got it into a usable state. There were issues with brownouts rebooting the Arduino, however with the Meanwell supply in-circuit those mysteriously stopped.

There are 3 power modes now for the module: 30W, 40W and 50W - with the first two using PWM, and the last one giving it all the beans. I wanted to PWM control the fan too, but decided against it since it sounded absolutely terrible at whatever PWM frequency the Nano is using.

It powers on to 40W by default, which is under the 45W max rating of the PSU.

Everything looks good so far running from the bench supply:

Now all that was left was to connect the internal supply, and the 12v vehicle input. I was actually supposed to use JST connectors for the Meanwell psu, but didn't have anything on hand - so improvised with crimping spade terminals and friction fitting those on

And the moment of truth. Up until this point I hadn't actually checked if the replacement psu was working or not

Looking good! I don't really like the LEDs though, so might do something about those in future.

You might be wondering how exactly I change the power settings... well since the manufacturer decided it was good enough to shove all the cables in the back, I did the same with a pushbutton 🤫

Glad to have the electric cooler working again though, feels nice to save large things like this from going to the landfill and extend their life a bit. Excited to hear any thoughts and feedback!

How nice of Windows to spam me with notifications when I temporarily fill my scratch disk, despite turning them off...

For me personally, trams are right up there. Aside from the main issue of sharing the roads instead of having a dedicated line, they really make it easy to get from one part of a city to another, especially for wheelchair users. They're usually as frequent as buses, but much faster. The stations are much more attractive compared to bus stops (on newer systems), and can really make an area feel much nicer IMO.

For those that have a bike, suburban and inter city rail is a strong second. The speed and ease of last mile mobility is what appeals to me the most. Recently took my bike across the country to my home city and it ended up being much faster than driving (by almost an hour) - the multimodal commute was pretty hefty, but lots of fun nonetheless.

The Retro Lite CM4 is a passion project by two modders StonedEdge and Dmcke5, inspired by the Switch. This emulation handheld is based around the Raspberry Pi CM4 and RetroPie.

While sharing a very similar look to the Switch, this thing is been built from the ground up, with a custom machined shell, PCB, and various other components. There's an optional custom dock with an integrated LCD, that can show the current game's cover art.

Personally, I think this is absolutely impressive. Hats off to these guys!

I've been in need of a bench supply for a while, up to this point I've been using little buck/boost boards with a multimeter to get the voltage I want when working on a project. The limitations of that started to show though, so I was after a more ideal solution.

After spending a while looking at various power supplies, I happened to come across this tiny adjustable supply. After binging a bunch of videos on it, I decided it'll do, especially compared to the absolutely chonky big alternatives.

Right out the gate, the aluminium casing feels amazing, but they could do with a bit of a stronger adhesive holding the glass screen cover in-place 🤦‍♂️ I'm personally not too bothered by this, but it doesn't set a good first impression IMO

A few seconds after pressing the glass back into place, the opposite end of the glass popped loose. At least I now know there are screws hidden under here if I ever decide to open this in future 💭

Aside from that, it has pretty reasonable specs for the size:

• Dual input, either AC (mickey ears plug) or DC 7-28v (XT60)
• 30V 10A (max output 200W on DC, max 100W on AC)
• Minimum output 1v 500mA
• 65W USB PD output (handy for the Pinecil I recently ordered to replace my old iron 😁)
• 200x200 IPS display
• AC input uses GaN parts

When watching the videos a few people complained about the absence of an XT60 to banana jack. This may have changed at some point, as one came with mine

The internal AC converter appears to supply 19V into the unit, which you can use via the XT60 connector at the rear. Not sure if intentional or not, but pretty neat nonetheless - as long as you dont accidentally leave a lipo plugged in there 😳

I'm not sure if its worth the price tag ($60-120 depending on where you look) when you can get a RuiDeng clone for under $30. I mainly jumped for this because of the size, integrated AC input, and that 65W USB-C. Voltage ripple is a little concern at lower voltages where some components may not be so forgiving...

Happy with the purchase so far though, can't wait to start using this for projects!

My old sandisk SATA ssd was starting to get really slow for some reason. The SMART data and the sandisk SSD dashboard app were saying the SSD was healthy, but its performance wasn't anywhere near what it was when brand new.

When benchmarked, it was all over the place with looong access times:

Sooo I decided to take the opportunity to upgrade the SSD to something faster - ended up grabbing a Transcend 512GB drive, with onboard DRAM

There were two problems though:

• My motherboard doesn't support NVMe (at least officially)
• My only available PCIe slot is an x1/single lane

After researching, I realised that the single PCIe lane would still give me almost 1GB/s in real world usage - even though its far from the 3GB/s the drive is rated for, it's double the speed of SATA and it's worlds apart from my Sandisk ssd lol.

Ordered an NVMe to PCIe adapter, and proceeded to chop up my PCIe slot to make it fit:

It took a while since I don't own a dremel 🤪

Once that was done, I kapton taped up the exposed metal bits on the NVMe adapter, that could short on a mobo heatsink nearby.

In it goes!! (The GPU went in after the pic lol)

After re running the benchmarks, OMG the speed difference is insane, although it's limited by that single PCIe lane.

I was caught off guard by something else though. After cloning my existing install to the new NVMe SSD, it booted right up, with the original Sandisk drive gone. My BIOS does not even recognise the NVMe drive as a disk drive, and there are no settings anywhere in there for it.

BIOS person, thank you whoever you are, you saved me needing to do more jank to get my unsupported NVMe drive working!

I am more than happy so far with the dramatic speed increase compared to the SATA drive. I can now actually shut down my desktop when I'm not using it 🥲

Specialized Como 2022 😍

Mine for a month as a part of a free ebike loan scheme im my city. The new scheme replaces our old dock-based ebike scheme which went bankrupt due to constant vandalism 😭

Loving the loaner bike so far, handling is pretty similar to my personal bike with the swept handlebar and rear pannier. The assist boosts me up hills with ease, and makes heavy shopping feel like nothing!

Wish I could own one but it's out of my price range at the moment.

Curious what alternatives to Tasker are available for Android. Slight preference to FOSS options, but any suggestions are welcome 😁

The last time I used one of these apps was almost a decade ago on my S4, kind of missing the convenience stuff I had set up back then - like adjusting the volume/opening apps/changing ringer mode when certain devices connect and disconnect, when the charger is connected etc.
