Hi there! I like to make things and sometimes I make videos about them. I enjoy woodworking, I'm into hobby electronics, and I like to come up with audio projects every once in a while. Check out my DIY videos and weekend projects and tell me what you think about them in the comments! (Affiliate platforms used: Daisycon, Amazon, AliExpress)
DIY Breadboard Power Supply
6 layer PCB FAB+Assembly - ONLY $2! :jlcpcb.com/?from=LeftyMaker
I decided to make my own breadboard power supply because I wasn't happy with any of the other options on the market. I wanted adjustable voltage, a voltage display, and safety features -- all at an affordable price.
So I partnered with JLCPCB to design and make this DIY power supply for breadboard use. It is based around the TLV767 chip and has output voltage ranging from 0.8 to 14 volts. Not bad!
Unfortunately, it may overheat under certain conditions, meaning that my PCB design does not provide enough surface area for cooling. Still, it is a good first attempt, in my opinion. It can provide 1W without issues, which is enough for many basic projects.

Here's how buttons on earphones work (hint: voltage dividers)
Переглядів 73728 днів тому
I just learned how the buttons on wired headphones work. I've always wondered because the 3.5mm plug has just four terminals, and they're already occupied by the left and right channels, the microphone and the common ground connection. To my surprise, it is not difficult to make multiple buttons work using just two pins the microphone and ground, in this case. (Does not apply to iPhones.) The b...

What a great channel
Noob question, but is it as damaging or dangerous when I use it with my powerbank instead?
I assume it's not impossible to damage a power bank with one of these
you have a lot of space for a 2mm chip... it's nonsense! you can use bigger voltage regulator! tiny chips are for tiny projects and... tiny currents 😊
The reference design by TI was much larger in area. I guess I trusted the 1A rating in the datasheet too much.
why not add some screws beside the chip and then screw on a heatsink? or maybe you can make it so that the chip controls the output voltage using a mosfet, which should also be able to solve the problem
Hmm. I should look into your second suggestion. I remember seeing transistors used with chips like 7805 or 317 to increase their current output.
I playwd with electronics a bit when i was a kid, and now my children are old enough to start. Ive been thinking forabout little kits like this to build together... Anxieuouly awaiting version 2
It's not out of the question for a DIY kit to come out of this one day :)
How long does it take to get fully charged?
about 1h 45min with a 100W charger
This is cool! I love vintage stuff, I collect myself
Unfortunatly there is no way of turning of the voice. Its included by default in the sdk and usually manufacturers dont change much and just compile in the default template because it saves money and they wont need to hire programming people. Also the sdk is not really fully documented well. Some boards that dont have usb sound card functionality can still have it implemented in the firmware and board layout (becauss again manufacturers are lazy to desugn their own thing and use premade schematics) but they just dont place a resistor or jumper disconnecting the usb data lines but leaving pads that can be bridged. I had some models like that. Also if you do plan on tinkering with the firmware, they can be programmed using usb in DFU mode. You have to put a specific signal across the usb pins to put it into dfu mode. The Dfu mode is burned into the bootrom of the ic so you wont erase the functionality. The chips also use UBOOT as their bootloader. They use JieLi's sdk to compile and flash the code onto the flash
Very useful info!
My 2x 200 Watt HiFi with boxes and multimedia server was still cheaper. How? 'My sponsor gave it to me. But lets be fair: that chip may be listed for 2cts, but 2 cts is not gonna get you that.
Disappointed. Why go through all the trouble, and it still requires a barrel jack. Make it use usb C PD atleast 😉
I am considering that too for v2.0, in combination with a chip to negotiate voltages. Funny enough, digikey just posted a video about that!
@@LeftyMaker yeah, I just saw that vid. Comet electronics has a 100W adjustable PD trigger . Works like a charm
does the ip2721 support 100W?
999.0 volts🤔🤔🤔🤔🤔🤔🤔🤔🤔🤔
I bought a 40,000 mah battery on ebay. It would charge my phone to at least 80%.
That's not then even fucking 40.000 MAH
Bro what phone do you have? 😂
@@ItsNeverMe me?
😂😂😂😂 biggest... joke.
What makes you say this?
Why?
The same thing existed in the UK, a service from the Rediffusion company. Their service lines were on the same poles as the telephone cables. They had four stations selected by a rotary switch, usually BBC Radio 1,2, 3 and 4. I seem to recall one of the channels switched to Radio Luxemburg at night. My grandmother had one until the early 1970s, when the service closed down because radios were now so cheap. The speaker units often had beautiful wooden cabinets and you would find them thrown out with the trash. I collected a lot of speakers and audio transformers from these, when I was a kid and just getting interested in electronics.
i dont have a solder machine
Be sure that your powerbank has the capacity noted on it, otherwise it might get confiscated, regardless of size.
Hmm, good point!
Well, if you're a technician or hobbyist you'll eventually use them. I'd use other methods to test the capacitors other than the AliExpress device
I live in America and have seen a couple of these over the years at thrift stores. I could never figure out what they were until I seen this.
In that history book, there is a pocket radio in a black case. I have one!
Thank you
I just want to say thank you for having the title in English and actually speaking English. I gave you a like for that reason. It doesn't cover the amplifier board i have however. All the other videos I have found on the board I have, have the title in English but they speak some foreign language and I HATE it when people do that. I consider them "clickbait".
Thanks! What is the board you have? I have since bought a few more, but I haven't covered them in a video
@@LeftyMaker It's a TPA3110 XH-A232 30W+30W 2.0 channel digital stereo power amplifier board. I bought it from Aliexpress.
You had the Bluetooth transmitter in the floor ! You should have tested the range when the transmitter was atlas 1.5 meters off the floor
is the floor lava or something?
@@LeftyMaker 🤦♀️
@@LeftyMaker comment was meant as constructive feedback ! It’s radio transmission 101, transmitters ideally need to be above ground or sea level to reduce *multi-path interference* and reduce *fresnel zone interference* having them higher than ground could have produced more meaningful result in real world scenarios
This is a communist thing?
🗿🗿🗿
So basically, they invented amplified speakers as reduced cost versions of radios. That seems pretty forward-looking, now.
The OnePlus is only drawing 18w from the power bank because it uses a proprietary protocol to communicate with it's original brick charger and then charges at 80w.. you can confirm this by taking a look in the USB A port of the charger (if that's what it is using) there will a extra pin in the connector other than the USB connetors..if it's using type c it's not possible to see the extra connetor but it's there..all of the phones which say fast charging like 100w 80w of Xiaomi OnePlus etc use their proprietary protocol and that's why don't charge at that speeds other than with their original charging brick
Not the case for my Samsung.
@@alluseri well your Samsung charges at less than 50w?
Christ is Lord
I use a usb-c to barrel for hp probook g1 650
I wonder if that clam is real
if that what is real? The capacity, you mean? Yeah, 21700 batteries can be about 5,000mAh each. 8x5,000mAh = 40,000mAh, so it checks out. If you want to get super technical, the pack is actually 5,000mAh at 29V, but a 40,000mAh figure would be more easily understood by most people.
Holy hec, that is massive! Need to invest in one...
yes... literally :) Though if you do the math, two smaller banks would be more cost effective
@@LeftyMaker yeah, but that 140W output? If you get two smaller banks you won't get that
Exactly the same 'Electronic device than the one that was in our hôtel room in 'Moscow in the years 1974.The only one radio station I suspected ( and still suspect ...)to spy customisers ( Mainly foreign tourists or' specialy 'invited people)
water boiling ☠️
He say nothing about chinesse comunications
Maybe you should consider buying real speakers too...
did they have those weird chimes
I mean, for two dollars I wouldn't expect it to have a big range, but this is amazing
That red colour ble module is surprisingly well built. I remember when I accidentally gave 8.4v into the right audio out channel but it survived because they actually added capacitors in series to both audio out ( the two big electrolytic ones ). The only only drawback to these is the god awful startup sound which yells " the bluetooth device is ready to pair " at full volume. I've seen people try to hack into these thru usb since this device actually shows up when you connect to usb and had no luck. But it's an interesting story. It is possible to reflasg the startup sequence for the other black module since it has a separate chip acting as memory and change the audios for the startup and button press sounds.
Geiger counters be like: I AM FIRST
will these work on single 18650 cells? if not, any alternatives that will?
I guess a red one may work. They seem to have a lower minimum voltage threshold.
🙏 thanks
i Always pick them up and use it in Projects.
cool!
For me, who always deals with used cell phones etc., it is of interest in that I can check when charging whether the charging socket or something else is defective. So, it is quite useful! at this Time i use a free App called Ampere to see besides other Infos how much Watt and Volts float.
But how can the mic still work perfectly with the buttons pressed?
Does the mic work while the buttons are pressed
