My acquisition of a Bean to cup machine is quite recent and I've been through several beginner's mistakes which I collected here while it's fresh.

My Synology DS213+ has been a reliable central storage for all the household for several years.

When it reached the end of its support lifecycle, I started looking for the most suitable upgrade in 2021: The DS720+ (after some hesitation with the DS 220+)

 

The most advertized coding interface for micro:Maqueen is the web based makecode.microbit.org, but it's not always the best way to fully exploit the features of the robot.

This is where the Kittenbot BLE SD module comes in handy.

This is a short recap of what's needed to set up a regular backup of a Synology shared folder onto an USB drive plugged on an Asus router (running with Asuswrt Merlin).

The information needed for this specific operation is generally scattered in different places, so I regrouped everything while it's still fresh from my recent actions.

If you ever print an object tall enough with the FLSUN Q5, you may see the tube/cable pair getting caught by one of the screws holding the right rod.

As a precaution, I designed this replacement for the "rod cup" with an extension that will cover the screw in question.
There's no need for more than one as the cable always tends to bend and get trapped on the same side.

The infamous Joycon drift is one of the biggest design flaws of the Nintendo Switch (along with the top right of the LCD screen detaching due to the heat generated by the processor)

With no sign that Nintendo ever fixed this problem with a better design, buying a new Joycon for 50$ seem a waste of money.

Fortunately, there are quick an cheap ways to resolve this.

If your fingerprint mouse stopped authenticating you after a recent Windows update, there's a quick solution to this.

Xiaomi MIUI overlay has greatly improved over the recent years and I start to like it.

What I like less is the increased amount of ads that sneaked in every corner of it

Obviously Xiaomi fail their promise to cut down on ads in MIUI 11.

The iPazzPort KP-62 is an RF remote I bought some time ago thinking it could be better than the H1 or even the unmatched TZ-P3.

XSS or Cross Site Scripting is a common vulnerability in software allowing attacker to inject code via the user interface.
Often, an input field just intended to collect a server address or user name will also accept entries of a different nature that will be interpreted by the system.

Low-cost IP Cameras, but also more professional ones, have been exposed to XSS for many years, a good reminder that such network devices should not be directly exposed to the Internet!
Hopefully that vulnerability is now well known and many manufacturers eventually "patched" their devices or reduced the attack surface by removing telnet and ftp altogether.

If your IP camera has a HTTP-based user interface, here's a working example of command injection (for learning purpose). This works great on old generation Veskys and Digoo BB-M2 (the pictures below comes from that model), and does not with the Wanscam models I tested.

First check if the admin interface of your camera as an FTP server settings page like this:



Then instead of FTP Server address, copy this command:
The actual FTP server test will report "Test  ...  Failed" which doesn't matter at all because the commands have been executed.

After that, use any telnet emulator, like Putty, and connect to the camera on port 23

As the owner of the camera, this trick allows you to gain full control on your camera.

This could as well be titled "My first steps in 3D printing" even though the long month waiting for my printer to arrive gave me time to document, watch, learn and prepare for The Day.

My old X10 equipment is being replaced with the cheap Wi-Fi-based sockets and switches from Sonoff and Tuya.

Before learning the difference between these competitors, I found myself with a mix of both "standards"...

The Alfawise V2 is a great mechanical keyboard with many RGB modes and assignable macro keys.

While most functions are available via the keyboard itself, its companion software is useful to reveal its full potential.

Some time has passed since my review of the YEPO 737A (64GB version), and I  was can tell today that this ultrabook is worth the addition of a SSD.

The next thing I needed was a SSD drive for a decent price and the Vaseky 128GB is just the perfect match.

Those who don't regularly visit the Casio Music Forums might have easily missed the news:
A firmware update (ver 1.60) has been released for the MZX-500 and MZX-300 in April.

Here's what it adds and how to minimize the risk to brick your keyboard with it.
