How We Fix Toys In Our Village For Our Kids

In this video I fix several Christmas presents. I show you the most common issues you can easily fix on toys. I recommend to start fixing toys with your kids. You can save significant amount of money and have lots of fun with your children. If you don't have any broken toys at home you can find some at flea markets.

A Vintage Voltage Tester from Czechoslovakia (Vadaska)

มุมมอง 2.5K4 ปีที่แล้ว

In this video I introduce to you a vintage voltage tester also called "Vadaska" made in Czechoslovakia. The version ZN1 I have in the video was made in 1981. The device is possible to use for testing the mains voltage, for measuring voltage and for testing 3-phase motors. In the video I show you how to use it for testing the mains voltage and for measuring voltage. 📚 References ➟ en.wikipedia.o...

Christmas Star Led Chaser With ATtiny13A

มุมมอง 12K4 ปีที่แล้ว

In this video I build a Christmas star led chaser without any PCB using the freeform technique. This time I took the inspiration from The Star of Bethlehem, which many Christians believe the star was a miraculous sign. For driving the star, I decided to use ATtiny13A which is AVR 8-bit microcontroller and several through-hole components. The code is written in C language in Visual Studio Code a...

Smiley Astable Multivibrator

มุมมอง 2.1K4 ปีที่แล้ว

In this video I build a simple smiley freeform circuit sculpture without any PCB. I took the inspiration for this project from the classic smiley form designed by Harvey Ball in 1963. I decided to use an astable multivibrator for building the circuit, which is a fundamental circuit of electrical-engineering and was first described by Henri Abraham and Eugene Bloch in 1919. I use through-hole co...

Soldering and Desoldering Pin Headers

มุมมอง 16K5 ปีที่แล้ว

In this video I experiment with soldering and desoldering pin headers. Soldering pin headers is not very difficult, you just need a little bigger soldering tip, for example 900M-T-K I use in this video, and ideally a lead solder wire for easier soldering. I use a 0.5mm solder wire for soldering in the video, but I recommend to use 1mm one which works much better. Most people are struggling more...

Lidl SilverCrest Smoothie Maker Teardown (2/2)

มุมมอง 3.3K5 ปีที่แล้ว

This is a second episode in which I repair a smoothie maker SilverCrest SSM 180 A1 from Lidl. This time I focus on testing a universal motor which is used in the smoothie maker. The universal motor should work either on alternating current or direct current and that's I want to test. In the video I also build a half bridge rectifier and a full bridge rectifier for testing the motor with direct ...

Huawei Honor 7 Lite Battery Replacement

มุมมอง 18K5 ปีที่แล้ว

In this video I show you how to replace a battery in Huawei Honor 7 Lite Dual SIM. Before replacing you have to search for a new battery on the Internet. You can do that by a phone model number which is NEM-L21. There is also another option to search for a new battery and that is by a battery model number which is HB366481ECW. If you replace a battery for the first time you should pay attention...

This is a second episode about the electronic hourglass soldering kit bought on AliExpress. In the video you will see a complete explanation of the kit. For explaining I use various simplified examples which I built for better understanding of the kit. At the end of the video you will see how I fixed the bug which I found in the first episode th-cam.com/video/V8NoMDddKCo/w-d-xo.html. If you wan...

NiCd, Nickel-Cadmium Battery Teardown

มุมมอง 24K5 ปีที่แล้ว

This is another battery teardown in which I take a look closer at rechargeable Nickel-cadmium batteries also called NiCd. Despite the fact that Nickel-cadmium batteries were banned for their toxicity at least in the European Union, you can still find them in old tools and devices. You will see in the video that it was quite challenging to take them apart and I had to use even a power tool. 🛠 To...

This is an introduction of an electronic hourglass soldering kit bought on AliExpress. In the video you will see all components delivered with the kit, how easy is to solder it and how to use it with a small bug at the end of the video. I recommend the kit mainly to beginners who want to improve their soldering skills and the most important information, you can buy the hourglass soldering kit o...

This is a second episode about building breakout boards for 8-bit AVR microcontrollers. In the first episode th-cam.com/video/08Ym00Ott1c/w-d-xo.html I show you how I built breakout boards for ATtiny10 and ATtiny5. In this video I focus on building breakout boards for ATtiny9 and ATtiny4 microcontrollers. This time I use only a soldering iron instead of a hot air soldering gun and it also works...

Conductive Solder Paste Flux

มุมมอง 2.1K5 ปีที่แล้ว

This is a video in which I test Pro’sKit 8S005 solder paste. This time I focus on its conductivity if you use it accidentally on a PCB. Really? Yes, this type which I test shouldn’t be used on printed circuits boards because of its conductivity. Therefore, I recommend to check parameters before buying a new solder paste to avoid accidents. How conductive it can be you will see in the video in w...

This is a video about programming AVR 8-bit microcontrollers in Visual Studio Code. This time I focus on programming ATtiny10, but the same way you can program other AVR 8-bit microcontrollers like ATtiny9, ATtiny5 and ATtiny4 which belong to the same family of AVR microcontrollers like ATtiny10. I demonstrate using Visual Studio Code on a blink program and I think that you will love Visual Stu...

This is a video about programming music in Arduino. I’d been thinking about that for a long time before I decided to show you how to play national anthem of Russia using a passive buzzer. In the video I explain what passive buzzers are, how they differ from active buzzers and how to differentiate which buzzer is active and passive. Then I show you a sketch I wrote for playing the Russian anthem...
