PDKH - my youtube videos (mostly beginners projects)

(1/3) > >>

There's so much I have learnt and enjoyed from so many other youtubers, I thought I would join the many others and give it a shot, and it seems that this is the right place to try a little shameless self-promotion  ;D

I'm sure that there's a bunch of stuff I need to improve on, but hopefully I'll get a little better in time.

Mostly they are just videos of assembling fairly simple, chinese-sourced, electronics kits. The vast majority of these (so far) have come with either very poor, or no instructions at all.

These are often really cheap, and thus are attractive for beginners, and with this particular kit featured below, there was a "trap for young players" in that the LEDs were "unconventional"* !!

* looks like they are mis-packaged, ie the flat on the package is on the wrong side!!

Digi-hourglass Part one

Digi-hourglass Part two

In another project I designed and 3d-printed a Macro Ring-Light for helping with making these videos

That's just a couple of my videos, my youtube channel is (so easy to remember  :palm: ) with a few other videos on it (I've only been making these for a couple of months), I didn't want to flood this post with embedding all of them at once  :-DD


So here's the 1st video of a more complicated kit I'm working on building up, it's a 1 meter tall RGB LED Tower, with about 550 RGB LEDs and a bunch of SMD parts to make it all go.

Amazingly there actually are instructions with this kit, with a bunch of photos with translated-english on them, which is helping to give some order to the build sequence of it all.

Anywho, here's the 1st part, just showing what all comes in the box.

Part 2 is coming soon

Part 2 is released into the wild!!!

In this video we get into building the main PCB which has a number of SMD passives & IC's. These are all soldered with a conventional soldering iron and 0.7mm leaded solder  >:D


Part 3 of this project, the next step is to assemble the PCB that interfaces between the main processor PCB and all of the "rings" of RGB LEDs, I'm calling it the Interconnect PCB.

Next up will be the rings of RGB LEDs ( approx 2200 thru-hole solder joints, this may take a moment or 2  :D )

Thanks for watching

Part 4 - assembling and soldering all the "rings" of LEDs, 4 pins per LED, 16 LEDs per ring, 32 rings = 2000+ solder joints using about 6 meters of 0.7mm 60/40 solder !!
Tried 1st of all soldering them my own way, then after a couple of "rings" I discovered some advice in the supplied manual and tried a couple of "rings" using their method. Their method did NOT give a warm fuzzy feeling, more like a murderous, seething contempt.   |O :horse: :-- (note to self, take the manual with a small shovel of salt!!)

Anywho, here's the next installment,

Next up will be taking all of these completed "rings" and then constructing a tower with them (another 500+ solder joints, then running another 3 wires from each LED "ring" to the Interconnect PCB.

Thanks for watching,
