These sort of soldering projects are a fun way to spend a bit of time - like others this is not too complicated (outside of a couple of components) but a good way to practice. I still feel like my soldering skills are on the very messy side of things, but after going through the steps in this kit I did have a functional radio.Most steps involve soldering pins, from resistors to capacitors to buttons, a socket for the main chip and the LED display itself.The FM tuner daughterboard and the headphone jack are surface mounted. The headphone jack in particular has one of the contacts that wraps around very close to the opposite side, so you definitely don't want to use too much solder there. The trickiest, however, is the little amplifier board that slots in and sticks up, as there is a significant amount of space between the contacts around back. For someone who knows what they're doing I imagine it's not hard, but I found it really fiddly to sweep the solder across the join.The battery compartment takes three AAAs and is unfortunately mounted from inside, so if you ever want to replace the batteries you have to disassemble the entire case via four screws. There's also a little micro USB port included in the packaging that they state to not install because it isn't supported, which is interesting. Maybe there's another variant that uses the same circuit board.Once assembled it powers up via switch and you can run an auto scan for signals. There is no manual seeking, but it did populate the presets after a quick run through the frequencies and the display does show which preset you've selected before switching back to the frequency (and eventually going dim, which you can bypass by shorting out two pads on the board). Volume is stepped too.It does work. The antenna isn't quite up to the task, though, as most of what I pick up is static where the few other radios in the house don't have a huge problem. Some stations do have audible voices or music, at least, so I don't think there's anything wrong with the radio or my own fumbling assembly of it. Headphone jack works, too, though I have to hold the plug in at an angle to get sound from both ears. I don't know if that's due to a defective jack or me screwing up its assembly, but nothing looks shorted, at least.Ultimately it's a fun little kit with a few tricky steps, good for practice. I don't know how useful the end product is as it has a lot of difficulty getting a clear signal, but it works and I'm always a sucker for seeing electronics through a clear case.

It's worth paying a little more for this compared to cheaper kits. The only trick part of the assemble is the surface mounted FM receiver card with its tiny crystal oscillator. I have a lot of fun with mine.

This electronic soldering DIY kit is an awesome way to practice soldering while building a working FM radio (87-108MHz). Once completed, the radio has a sleek design and great sound quality!It even comes with a headphone jack for private listening.The LED display makes tuning easy, and it’s a great hands-on project for learning more about electronics. Perfect for both beginners and enthusiasts looking to improve their soldering skills.
