Gear up, electronics enthusiasts! In this installment of InTheMail, we’re diving deep into a treasure trove of tech goodies that are sure to elevate your workshop game. From cutting-edge ESP32-C3 development boards to sleek braided heat shrink tubing, we’ve got you covered. First up, we’re exploring the world of the ESP32-C3, a powerful microcontroller based on the RISC-V architecture.

We’ve got not one, but three dev boards to showcase, each with its unique features and form factors. Whether you need a compact solution or a board packed with extras like USB-C ports and status LEDs, we’ve got you covered. But that’s not all! We’re also taking a closer look at braided heat shrink cable sleeving, a professional-grade solution for your wiring projects.

While it comes with a few caveats, like a higher price tag and stiffer finish, the braided look is undeniably sleek and polished. Continuing our exploration, we stumble upon a rather intriguing (and slightly concerning) product – a pet positioning GPS locator with a built-in microphone. While its tracking capabilities are questionable, the ability to listen in on conversations raises some ethical concerns.

We’ll leave it up to you to decide how to utilize this technology responsibly. Moving on to more practical solutions, we’ve got our hands on a nifty hand wave sensor and a touch sensor designed for furniture integration. These clever devices allow you to control lighting and other low-voltage DC applications with a simple wave or touch, adding a touch of convenience and modernity to your projects.

And speaking of lighting, we’re diving into the world of LED tape controllers, specifically one powered by an ESP8266 module. While it may not be the ideal choice for driving analog LED tapes due to potential flickering issues, it’s a fantastic option for digital LED tapes, offering seamless integration with popular open-source firmware platforms like Tasmota, WLED, and ESPHome.

But wait, there’s more! We’re also exploring a budget-friendly Apple Watch charger clone and a unique stainless steel scrub cleaner for those who value a sparkling workshop (and cast iron pans!).

Welcome to a new edition of InTheMail, where we unbox and explore the latest additions to my ever-growing collection of electronics gadgets and tools. This time around, we’ve got a diverse array of items, from smart home devices to specialized tools for electronics enthusiasts. First up, we have the Aqara Magic Cube, a nifty little Zigbee switch that can be programmed to trigger various actions in your home automation setup.

With its built-in accelerometer, you can simply flip, rotate, or shake the cube to adjust things like lighting or appliances. I’m excited to integrate this into my smart home system and ditch those pesky wall switches. Next, we’ve got a fingerprint lock that I plan to install on a cabinet or drawer. While not meant for high-security applications, it’s a convenient way to keep certain items private without the need for a physical key.

The build quality seems decent, and the external power port is a handy feature. For my electronics workbench, I’ve acquired a silicone mat, clean room wipes, and various cleaning brushes. The mat will provide a nice, non-slip surface for my new digital microscope, while the wipes and brushes will help keep my workspace spotless.

Speaking of microscopes, I’ve also picked up a set of AWG32 stranded wires in various colors. These ultra-thin wires will come in handy for intricate repairs, modifications, and bodges on PCBs. One item that caught my eye is an ingenious Apple AirTag mount designed to fit seamlessly into a bicycle’s water bottle cage.

This clever hiding spot should deter thieves from spotting the AirTag, making it an effective anti-theft solution for my bike. For my electronics tinkering needs, I’ve acquired a set of RFM95W LoRa modules and a DSLogic Plus logic analyzer. The LoRa modules will be useful for wireless projects, while the logic analyzer will allow me to analyze and debug complex digital circuits with its impressive 400MHz sampling rate and 16-channel capability.

Last but not least, I’ve got a unique ESP32-based WiFi display unit that pulls data like weather and time from the internet. While primarily a demo unit, it’s a cool hardware platform that could be repurposed for various smart sensor network applications.

Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. Before I get started I’m gonna take a second to remind you to subscribe to the channel and hit the bell notification icon because that’s the only way you will know for sure when I upload new videos. I’m gonna start with an item that’s actually disappointing, this is a mini portable vacuum cleaner but I only realized this after receiving the item, because the seller of this item was advertising this as a dust blower vacuum cleaner, it’s the usual keyword stuffing that aliexpress sellers do.

Voltlog #269 – 11.11 Shopping Suggestions For Makers

Welcome to a new Voltlog, it’s November and that means the biggest shopping event happening in Asia is coming up, I’m talking about the 11th of november. There are some numbers published for last years event and it seems they registered more than 30 billion in 24 hours in sales, yes you heard right, billions. So it’s a very big event with nice discounts and opportunities for makers like us to get some new gear. That’s why I prepared this video which will be published 1-2 days before the event so you can get some ideas of stuff that you could purchase. I assembled a list, these are products that I’ve tested and used myself which I think are good value for money and a nice addition to any hobbyist lab.

Voltlog #259 – InTheMail

Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. We’re going to start with this small white box, which looks very uninteresting from the outside but contains something really nice, it’s a machined aluminium heatsink, designed specifically for the raspberry pi 4 and inside the box you get the two halves of the heatsink plus some mounting screws and silicone thermal pads.

There is a decent amount of aluminium in this heatsink, and we can see it has these rectangular raised islands for contact with the main chips on the board, so this is where the silicone pads will go. This is a completely passive heatsink and that’s what I was looking for but if you want more cooling power these are also actively cooled heatsink. feel like I should test this in a separate video to see how efficient it is when compared to a no heatsink solution which we already know doesn’t work well with the raspberry pi as it gets pretty hot. So we’ll leave this for a future video.
