Just finished building this kit, Hardest part was the SMD chip but I used my new iron and it went together pretty good but difficult. I need to invest in a moist sponge or a souring pad in a small container so I can keep my tip clean. I've had to make some modifications to the kit and I used a different 3AA battery holder because the one that came with the kit is poor quality and the batteries just popped out but I used one from another project. The zip ties broke on mine so I just hot glued the board to the holder. I added an antenna wire to the ground as it seemed to come in better when I did that. Just waiting for the glue to cool but this kit sounds crystal clear with my earbuds and even better on my DIY headphone amp. I'm listening to it as I type this and it sounds awesome.

Great fun video, thanks Todd. I just picked one up from AliE for 2.75 US bucks with free shipping. Cool....it is not often that things get cheaper a year or two later. Thanks.

Looking forward to making this tomorrow morning. I love waking up and getting stuck into these kits. I'll have your video on hand as this will be my first foray into surface mount soldering. Thanks.

That looks like a fun little project! It gave me some flashbacks of the ham radio exam...

Fairly easy to build. Just a little challenge with the surface mount IC.

Nice video and perfect timing! I ordered several of these same kits, and they just arrived today. No instructions so it's nice to see this and know it actually works.

It works very well, loved listening to the little kit radio in Stereo :) Also being powered by two AAs is a plus.

looks fun and the chip is interesting. with i2c this thing could be connected to microcontrollers or a sbc like the raspberry pi.

BaGuS 👍👍 KeReN 👍👍

anyone know where to add an antenna to this? I can only get 3-4 stations.

Very neat little FM radio. It would be cool if there was a case to go with it, to protect the circuit from the elements. Also, an tuning and power indicator LED would be good on that. Regardless, it's still great. Cheers!

Thanks Dwayne, I have a few more FM radios coming from them...keep watching.

Is there anyway to improve the aerial??

In the schematic, it shows pin 6 of the RDA5807FP connected to the battery + (3V). In the datasheet for the IC, pin 6 goes to ground.

I built this, and it works good. I want to put a channel display on it. Is this possible? What display to get? Anybody?

Hello. Does it matter which side to install the buttons? Thanks.

My kit didn't come with headphones :(. I got gy18041

Hey dude, thanks for the great walkthrough. Mine is powering on, volume controls work, and I can flick between stations, but all I'm hearing is white noise. I think it might be the antenna? One hint is 0V across the resistor and the inductors (but it's still turning on) and 2.7V across the caps. Any pointers appreciated.

Sounds like a nice kit to build.

The main chip uses I2C to get instruction. I donot understand how this circuit is providing I2C instructions without a proper microcontroller. Please help me understand this.

imagine there are still people who never heard Rick Astley, Edward Khil or The Living Tombstone. Thanks a lot for this.

I did near perfect soldering on this EXCEPT for the chip. I saw a video on the ali express page that showed him smug the whole thing with solder. I thought I should try it... and I created a smoking short... I had tried to do it the way you did at first. I think I might have actually gotten it to work. I'll need to order another kit. I want to make this one work!

lots of flux, try to tack down to corners, and put a bit of solder on the tip of the iron and quickly drag the iron across the pads in one motion. check for bridges. If you get a bridge, dry the iron and put it on the bridge and drag the iron away to help pull the excess off.

@Hotshotter3000

@@todderbert Yeah. Flux is not something I ever used. I've been getting much, much better at soldering to the point that I make beautiful little plops of solder where the holes are. But those are in the 'normal' holes. This little IC is so tiny that I think I melted off the legs. Even if I didn't try to imitate the aliexpress video I would still have messed it up I think.

I may look for this radio if it's on amazon because I have a pop up speaker that has a similar tuning style FM radio which I don't mind. I wish it had a power on LED but that's ok since it draws 19mA when on and you have 2800mAh batteries. I have a 3 watt amplifier from Adafruit that I may use for this or one I made from a Gameboy advance sound accessory that had an amp and I think a light.
