Hi Moekoe,I continue to implements your cube after some troubles with leds it's now ok.Time to build the acrylic frame, I would like like it in black or grey.Can you tell us the level of transparency / opacity that is acceptable. it it better black (it's often 0-5% of transparency) or gray or something else ?It's quite expansive (80e) and as I can only order on internet I want to be sure to order a color that will be the good oneThxChristophe
Hi, Yep i finished to solder wire and leds. I start some test and after a very nice first shot with only the top matrix working very well, I'm stuck since I tried to make the both working together.I think it's related to how my teensy is powered (I put the top matrix + 4 lines on one supplier and 6 lines + arduino on the other supplier) and unfortunately nothing is working. I'm becoming crasy, trying to pilot one matrix is swithing led on the other ...)Is there any attention point on arduino and ground ? The power supply must be connected in parallel or series ?
HiTo get u in touch, we did some progress, we are closed to finish wood work. Leds & teensy are there but still waiting power supply from China ...
I get a couple of questions on your breadboard picture:* Voltage is 5V, all components works under 5V ?* Why the buzzer is plugged on the wifi module (and not directly bound to the tensy)* What is the component V-REG ?* The switch in the middle is gonna switch off/on only the wifi ?* Why using a Tensy (looks like it required special IDE) ? Is there a chance to work with any other arduino ?* Last but not least: should it be possible to catch sound through a mic (I though at equalizer capabilities) ?RegardsChristophe
Many thanksI know what to do this winter ;-)I'll keep you in touch if we success or if we need some additional help but it sounds pretty clear.Christophe
Amazing ! This is really nice, congrats !I thing I'll try it with my son.Wood working and coding is not a pb for me but i'm a newbie for the electronic part.Is it possible to get some additional pictures on LEDs connection (Do you use connector clip, welding, ...)finally if you could provide some ebay / amazon link for electronics parts (arduino, buz, ...) I'm able to do some search on internet but as it's my first try I'm afraid to buy a lot of wrong items before success :(ThxChristophe
