PCB & Schematics for Heliox LED dice

Last crawled date: 4 years, 1 month ago

Next more things.
Why limit us on counting to 6 only.
Change the game a bit, take 9!
New PCB (BETA) files
Possible outlines are 38x38mm and 40x40mm.
See the pics.
Proposal (BETA)
3x3 LED front face pcb layout
3x3 LED electronics circuit
-some 3D redisign work needed on the top part
-requires changes on the firmware for using all LED's
-requires changes on the front to allow 9 LED, obviously
-requires mounting some parts on the copper side
See my first made pcb with the ATTiny soldered onto the copper side.
Take care on flipping or not the layout when printing for toner transfer method.
The DIP8 package must be oriented (pin1) as shown from the copper side this time.

The electronically made copy of the blue print picture (pdf).
Here you are.
The exact hig resolution copy of the low res picture, recreated electronically.
AKA the Chineese Copy Cat Methode.
Did not know before how easy the copy cats can do their work with no effort.
Have it drawn line by line, dot by dot.
Positioning the frame centered was a little bit tricky.
Exported the graphic at 1200 dpi.
The picture size including the empty white area is 60x60mm.
.
No more Kiwi pcb files. See below.
The new version of the old pcb V2 is ready to print.
Have not produced the pcb by myself. could be done later on.
Not now.
See the preview shows it perfectly centered.
For those looking close up.
The red lines are made by the picture editor not the layout designer.
No problem here.
The files:
-Picture of my remix of the pcb seen on Heliox dice videos.
-The Schematics, I have improved for better reading, provided by KiwiGrinder.
Thx.https://thingiverse-production-new.s3.amazonaws.com/assets/85/55/9e/6f/cb/Schematic_SLP.jpg
-New old pcb v2 size 2*19.6mm on each side. Do the math ;-)
One layout picture has an extra wide brim for users using the toner transfer method.
It has a fat trace surrounding the outer shape lines of the design.
I know from own experience.
Think of all the users with the clothing irons, please.
It is not all High Tech all over the planet.
DL the zip-file. It has the design files.

Regardles of the flaws I have noticed, it looks good from the outside.
Merci.

See a short video sequence of the black beauty.
Rename the "dice red on black.mp4.txt", by removing the .txt extension.

Nice find:
The most robust (mechanical wise) LED dice I have seen so far:
the Dutch Velleman PMK150 dice.
It gives a clue how things could be made from two pcb.
The standoff bolts give mechanical strength.
They serve as conductors too, replacing the needed 5 wires.
It has a great educational value for the DIY designer even if not build (copied) identically.
The PIC12C508A based dice designed by Dutch folks:https://files2.elv.com//public/10/1020/102036/Internet/102036_f02_plwuerfel_600x600.jpg
They have provided detailed build instructions and the schematics in the user manual printed on paper, for DL as pdf-file on the Velleman server.
But no software as usual.
It has the mechanical vibration detector (tube with balls), no toxic Mercury.
Conclusion:
Big value for the kids at home.
Great value for the money. This time it would be a good buy.
Some build videos can be found on YT.
iDoc has made one.

Something I'm missing on the pcb still.
-No reverse polarity protection
Add a diode , solder polarity opposed to the power over the power leads.
The cathode (the end with the ring marking) goes to the "+" pole.
-Have you put on a smoothing / filtering capacitor?
Every digitally working chip should have a smoothing capacitor, ca 33-100nF.
Can be made easily. Soldere one on the Vcc and ground pins of the ATTiny.
.
I'm busy making much more pleasing better design work.
Look here:https://www.thingiverse.com/thing:3926580
Have all parts drawn from scratch.
This is not the usual Chineese Copy Cats work,
the freeking me out, stupidly ignorant Steve Jobs complained about.
RIP, never come back, better go to hell.
The top bottom parts have mounting screw holes / standoffs.
Nothing will come loose or fall off easily.
For software development I have flipped the board.
Have the ATTiny on the top for easy removal.
I WANT THE SNAKE running, still.
.
Removed the Kiwi design files.
The reason.
His design might work if you are using lithographie.
but not with my cnc mill anf printing toner on pcb.
Thin traces between pin. Thin solder pads.
THE END
