Great kit with easy to follow instructions!
This is a really good intermediate kit, especially if you want to try a few surface mount components. This kit has a great variety of component mounting styles. It also has two ICs and a few capacitors that are surface mount to test your skills. Don’t worry, they are fairly easy as far as surface mount goes, you will want some tweezers for the smaller ones. I originally thought it was just a clock and spectrum analyzer, but there are mant variations of the programs to select from. I would recommend this kit and didn’t have any problems, started right up.

Good Entertainment Value, and A Decent Clock
Assembly â this is a pretty easy build for a hobbyist thatâs comfortable with the SMD components used. My construction time was well under an hour, though I did cheat and use a reflow oven for the surface mount components. Note that the capacitors supplied are not marked in any way. One extra of each cap is included, so the three parts supplied are actually the two 22 pF values next to the crystal. The other two parts are the 0.1 uF value (104), which is only used in one location on the board. I opted to discard the plastic film supplied for a display cover and merely turned down the LED brightness via the menu instead.Operation â It is pretty entertaining to watch, especially when music is playing in the shop. I really like the 8×8 matrix displays, and the pure green color is attractive. The clock is a good addition to my collection of digital timepieces.Best features â Backup battery retains time during power failures. Battery is supplied (even though the Amazon description says itâs not). Dual USB connectors for either side or back connectivity. Cool sequential sound-driven visual effects, including a âgraphic equalizerâ effect and one mode which has a numeric indication of relative sound level. And they got the 24 hour time display right (so many clocks seem to leave out the leading zero which I feel should be present from 00:00 to 09:59 with military time).Areas for improvement â a light sensor for automatic dimming instead of an adjustable block of dimming times (ânight modeâ) would be a great addition. Takes lots of irritating button presses to set minutes if youâre close to the bottom of an hour â two button user interface would make for a much better user experience when navigating the menu. Also, when making clock adjustments, seconds should be reset and held at zero until the last menu item is exited (pet peeve of mine is not being able to set seconds accurately â though granted, this is somewhat pointless since uncompensated tuning fork type crystals drift up to a minute per month depending on ambient temperature). The rather short 8 second timeout if you wait too long to press the button should be increased to something reasonable like 15-20 seconds, or better still, disabled entirely (automatic timeouts are annoying, in any case). You canât leave the visual effects in a particular mode; the clock always cycles through all of them. No bootloader to update the firmware via USB. No date display. No automatic DST adjustment. Soldering the smaller parts may be daunting for some people, especially the microcontroller. Finally, need to provide a download link for instructions in PDF format, in case the clock disappears from the Amazon website some day.Summary â Deducting one star for the niggles above, but for the price and the entertainment value, Iâd definitely buy it again.

It was fairly easy to build and has a ton of options.
I wanted to increase my skills in surface mount soldering and this kit definitely helped in that. My only con is that I wish there was a mode that would just display the time all the time without the gimmicky graphics. Yea, they are cute, but personally, I really just want to look to see the time. It is a cool display though!

Fun but medium quality
All of the parts were in the package. Nice practice kit. But the display is less than awesome.

Tough.
Small parts to solider without a heat gun.

Difficult kit, but well designed
As others have mentioned, thereâs smd soldering involved. Itâs not easy even if you have the right equipment. I used a VERY fine point iron and still had to unbridgeable several connections as well as use the spare capacitors after I destroyed the first attempted component. Once completed, however, this is a nice device. Worth the effort.

Be forewarned! 2 of the IC chips are tiny smds
I just received this kit and I’m trying to figure out how I’m gonna solder the SMD controller chip to the board! It has a bunch of tiny leads coming out of all four sides and they are VERY close together. I’ve never soldered anything with leads so close together and I’ve soldered a lot of kits! I’ll probably have to use a magnifying glass so I can see what I’m doing and avoid bridging the leads with solder. Usually, when the leads are that close together, the chip comes pre-soldered to the board. Had I known it wasn’t, I wouldn’t have bought the kit. I gave it 3 stars for this reason, but I’ll give it a try and see how it goes. I’ll come back and update this review when I’m done building it.Update on 3-30-24I tried soldering the tiny controller chip to the board with no success. I tried using a magnifying glass to help see the tiny leads, but still ended up bridging the leads and making the chip and board unusable. I found out later through Google research that the way to do it is to use solder paste and a rework station with hot air to melt the solder to the connections.Update on 4-14-24Returned the first kit I messed up trying to solder the ridiculously tiny smd controller IC. Got another kit and tried again using solder paste and reheat hot air work station as I mentioned above. However, I still had a hard time soldering the 4 sided TINY controller chip using the correct SMD soldering technique. I finished soldering the rest of the kit and tried it out. When I plugged it in, the display was blank and it didn’t work. NOTE – THIS KIT IS NOT LIKE ANY OTHER KIT I’VE SOLDER USING A REGULAR SOLDERING IRON AND SOLDER. This is because the controller chip and leads are so tiny, it’s almost impossible for the average kit builder to solder. All other kits I’ve built would have a tiny chip like this already soldered to the board. It will be the 2nd time I’m returning the kit for credit. It needs to be made clear in the description about this tiny controller smd chip. The description is very misleading!

Recommended for beginners. Good first step into SMD components assembly.
The build is straight following the clear instructions. Moderate to easy level, half of the included components are SMD but can be easy soldered using a regular iron (with a thin tip). The hardest part was to identify the tiny capacitors (as they are not marked). Overall assembly took me around 45 minutes. Another 15 minutes to navigate and understand the menu. Very relaxing project. My next step will be an acrylic or wooden case.
