    it took some digging around but found the instructions. I like the look of this clock looks cool on the shelf. this kit has some smd components and requires a hot air gun or a conical tip soldering iron I chose to use a soldering iron to assemble the whole clock.

    Challenging kit for iron assembly but totally doable with care. After fixing an assembly screw up (my fault) it worked perfectly and actually looks way better than expected. NOT a beginners soldering project, but perfect for someone wanting to try surface mount devices with an iron or similar. ZERO directions included.. haha.. which kind of makes it more fun in a sick way. Resistor placement is super vague and almost impossible to figure out without being a total nerd, so the correct locations are: R1 & R2 = (105) ..... R3, R4, R5, R6, R7 = (103) ..... R8 = (202) ..... C2, C4, C5 = (104 unmarked brown colored), LED1-LED2 ( direction important. look at back of component, see the tiny little arrow head on the back. Square pad is positive and should be back of arrow, and round pad is Negative and should be tip of arrow). The other components make sense with the board markings. With an iron the chip is tricky to solder without bridging pins etc, but check out some yourube vids on diy SMD solering and make sure you have some flux paste and desolding braid on hand. Not hard, but also takes some care. Cool kit at a fair price.
