NEJE DIY Large Screen 4-Digit Green LED Electronic Clock Kit (DealExtreme – SKU383449)

Unboxing, organizing and test fitting of components, and then soldering with final assembly.
FAQ: What’s the liquid you’re applying when soldering? It’s liquid flux, and it allows for much easier wetting of the leads and pads with the melted solder. More info here:

Sorry about image quality, but the recorded video was meant for documentation purposes, and not for a YouTube video. I decided to upload it anyway, as the kit was too nice to not share.

just wondered if you have made or are planning to make a video for beginners to electronic kit making. Along the lines of the basic tools required such as soldering iron type, suitable solder ,which multimeter etc etc . Or maybe just a quick tour of your stuff. It would be interesting.

Choriposter 24/7 says:

maybe you replied to this before, but why do you clean the boards with alcohol

FrankTheCat says:

I just built the red one of these. The board went together quickly and easily– the case, not so much. A couple of the pieces of acrylic were warped pretty badly and I ended up having to make a mess super gluing the front panel on. The clock itself works great, though! Thanks for the link to the English PDF on how to use it.

Nice kit, nice quality, HUGE display, but I can’t figure out 12hr mode… seems to be 24hr mode only, nor do I see temp.
It took me a couple shots to get the case pieces right, too!

how to buy this kit, send me the link

Mr.Z says:

Anyone know how much the watch gets mAh for 1 hour action? Because I would like to use cell lithium- ion battery to power the watch and I’m curious how much is enough one charge?

Ron Thompson says:

Be careful I just bought that clock,not all those company’s include the case ,mine didn’t come with a case,if you don’t see the case in the add ,don’t assume it comes with one,I did,and mine didn’t come with one

Ron Thompson says:

I do like the kit,and your video was great

Ron Thompson says:

What kind of solder are you using lead or lead free ,and what’s in that bottle .

yusef basraoui says:

SilkiE says:

your music is terrible

Bruce Woods says:

Cat got your tongue? I hate the music only, needs commentary

Arsenio Dev says:

LOVE the videos, extraoridinarily well-produced. Subbed and will be coming back for more!

Todd Gemmill says:

Thanks for making this video, it was fun to watch. Can you tell me where you picked up those Tech tweezers? I’d like to get a set for myself. Are they #6 Dumont’s ? Tks!

ttcbaby sg says:

HI, any way to convert the dc supply to battery?

max factor says:

what is the liquid that u apply to the joints?

zysis says:

Time to admit in drunken honesty that I’ll never make a circuit board, or have an interest in doing so. I just come here because the music is good and watching this is relaxing for some reason. I blame clocks for bringing me here. I’ll just uh… go back to my corner now.

EDIT Oh and, I love all your vids, I’ve watched them all many times over. Really clean and well presented.

Brian Dos Santos says:

Is it 12 or 24 hour format?

Michael Beeny says:

Interesting, I have just built a similar version of this kit from Bangood. Clearly originating from the same suppler but a number of interesting differences. See my version here, see what you think.
