Voltlog #229 - What’s The Smallest Digital RGB LED?
$2 for 5 PCBs Any Color https://jlcpcb.com In this video we will take a look at what I believe is the smallest digitally controlled RGB LED that you can easily purchase. I will also show you how to drive these with a 3.3V powered controller.
After replacing the battery in this iphone 5c, the phone kept rebooting itself without any apparent reason. By using a schematic and board view of the logic board I was able to find the fault and repair it.

So in the end I would say this new AN8009 model is just as good as the AN8008 and they are both great beginner multimeters but they can also be good for the more advanced user who better understands their limitations.

I started this project to solve a problem I was having and that is constant watering of these two pineapple plants that I’m growing. You know how things work, sometimes you forget to water them and sometimes you are away for a couple of days and there isn’t anyone home to water them.

$2 for 5 PCBs Any Color https://jlcpcb.com Welcome to a new InTheMail, my usual introductory line would say this is the series that will touch both your passion for electronics and your bank account at the same time but in this episode it’s not about electronics, it’s mostly some outdoor / camping / surviving gear that I got for my adventures and I think some of you may find this interesting, especially as our social behaviour is changing now and during this summer we might spend more time in the nature.

High quality PCB Services https://pcbway.com/g/01s7lR Welcome back to the channel! In this follow-up video, we address a common concern from my Rigol DHO800 series oscilloscope review – the lack of built-in WiFi. Today, we're diving into a fantastic solution that involves a simple hack using a TP-Link TL-WN725N USB WiFi Adapter.

#RigolDHO800 #Hack #WiFi
00:05 Introduction
03:52 Wifi Procedure
05:40 Hot Swap Test
06:40 Brightness Adjust
Credit goes to the knowledgeable community over at the EEVBlog forum for discovering that the Rigol's Android operating system already contains drivers for the Realtek RTL8188 chipset found in the TP-Link adapter. This makes the upgrade essentially a plug-and-play experience!
To perform this upgrade, you'll need the TP-Link TL-WN725N USB WiFi Adapter (look for WN725 ver2 or ver3 with RTL8188 chipset), a USB hub, and a keyboard. The process involves accessing the Android OS settings through keyboard shortcuts, connecting to your preferred WiFi network, and then tweaking a few settings.
Keep in mind that this isn't officially supported by Rigol, so there might be quirks. The GUI won't show WiFi connectivity accurately, and there's a chance it's not hot-swappable – meaning you should have the adapter plugged in when starting the scope. Despite these minor inconveniences, once set up, the scope will automatically connect to WiFi upon every power-up.
After the hack, you gain the convenience of accessing your oscilloscope over the network. I recommend assigning a static IP address through your router settings for consistent access.
Additionally, we tackle another gripe I had in the review – the lack of brightness control in the GUI. With the keyboard shortcuts, specifically Windows + N, you can access the Android global brightness settings, enhancing your viewing experience on the glossy screen.
This hack transforms the Rigol DHO800 series into a more versatile and connected tool. It's an excellent compromise, especially considering the affordable cost of the TP-Link adapter.
