One of the worse soldering I have seen , terrible.

I just found these little kits online. Cheap. I'm going to order a bunch, and teach how to make.

thanks for hiding the wires with your ultra zoomed the fuck video

I brought one as was going to actually use it for a egg, but slowest it goes is about 30 seconds, so useless

They are not tubes, they are transistors.

mine got issue after how many days its noisy somthing like no signal idk

Nice project brothers 👍🔔🙏 4:16

Thanks for the video! : ) Can you modify this to be sound active? Like ... to advance the leds according to beats of the music by somehow add a microphone somewhere in there? I have this kit but if there is a way to solder it with this extra I would.

technical question: is the joysticks replaceable?

This is really helpful. Thanks! I was really hopting the ant would survive tho :-(

The microswitch have a sense to install on the pcb?

Hi do you think there is a easy task to do a DAB/DAB+ Fm and internet radio combined, I have seen a lot ot ESP32 kits for internet radio only built nothing that combines internet and FM/DAB while chips that offers the combined functionality like the frontier tech that you find in expensive audio modulles like Ruark are not sold to end retailers, Any ideas?

Good video bro. No bullshit talking/yapping just straight to the point plus I really like the selection of classical orchestra music you chose. Keep it up bro👍

Bom dia qual é a voltagem do circuito

Estereo?

Radio fm casio?

Супер.

Spoilt by no commentary

Why the heavy overbearing intro music

Saya suka

Can i use battery instead?

Battery replaceable?

Info review that black retekes radio

Nice video, but not two thumbs up... i see a dead blue led to the right of the left red leg. either it was installed backwards or it was cooked by the iron when installing... replace it with one of the extras that came with the kit!

AM stereo?!ha ha...

Esta muy buena esta radio

Your radio did not work because you did not connect the broken lines of the circuit. I think there are five lines that you need to connect.

hi Z Z... ' here is my LED kit... ruclips.net/video/gtF9X4cejkI/видео.html

Hoe can I get the clock kit please inform me.

hi Z Z... ' my 81 LED kit is finish and beautifully color LED plus all 81 LEDs lights stays on without flashers and yes flashers, tooo

will u tell me where it can be repaired in pakistan and contact number

Do not buy. Got 2 different models with faulty battery. Just blinks blue. If I plug in battery led stays reds for a minute and turns off.

What kind of transistor?

What's the voltage supply??????

sorry, music is distracting. rather hear in words what your finding out.

অনেক সুন্দর কাজ, কিন্তু ব্যাটারির হেলথ কমে গেছে মনে হয়

' how can all 81 LEDs stays lights on without flashers... no move X / Y

Какой чип стоит? Si4825 или KT0936?

numberTransistor ؟؟

Hi can we use this Circuit 50 led

Sir plz i wanna buy this whole pkg ...plz sir koi treeka btay plz k ye kese Pakistan me khreed skty hain mujhe ye product chahiye kisi bhe keemet pr

Kitne ka hai bhai.❤️❤️❤️

The quality of this video is exceptional.

🎉🇩🇿👍🏻

Hi zero-zone Thanks to your description, I managed to set up this module for my own purpose. I hope you don't mind some constructive criticism. I understand that you are not a native English speaker, and I'm afraid to tell you that your English is not easily understandable - no offense intended! Therefor I tried to write an improved alignment procedure. However I am no native speaker myself, so please pardon any errors I made on my own. Equipment needed: Adjustable power supply DC Voltmeter Small screwdriver Example: For a single 3.7 V lithium cell, voltage range is from 3 V (empty) to 4.2 V (fully charged). If you want to check a different voltage, just substitute the above voltages by your own minimum and maximum values (see points 3 and 6 below). Procedure: 1. For the alignment it is recommended that you bridge both the J1 and J2 solder pad pairs with a small blob of solder (set to 'always on' and 'bar display' instead of 'dot display'). 2. Connect the power supply and the voltmeter in parallel to the PCB. 3. Set the power supply to 4.20 V, check with the voltmeter. 4. The LEDs will show some arbitrary pattern. 5. Adjust trimmer potentiometer RV2 so that the 10th LED is just coming on. 6. Set the power supply to 3.00 V, check with the voltmeter. 7. Adjust trimmer potentiometer RV1 so that the 1st LED is just coming on. 8. The settings of the two trimmer potentiometers have a small mutual effect, therefor repeat steps 3, 5, 6, and 7 two to three times. 9. If you want the tester to be on only when pressing SW1, remove the solder blob from the J1 pads. 10. If you want the tester in 'dot display' mode, remove the solder blob from the J2 pads. Comments (my 2 cents): I fail to understand the purpose of resistor R1 (the one on the same side as the LM3914 chip) since it is connected across the supply. You can omit it without any negative effect. The LM3014 data sheet recommends an electrolytic capacitor of 10 uF. Its voltage rating must exceed the maximum voltage you use the tester for (35 V recommended). You might want to connect this capacitor instead of resistor R1. Kind regards Robert

Trasformer connections maybe are wrong. There are 4wires but I see only 3 wires welded. The 2 thin wire go together in the center hole.

Pretty sensitive for the price.
