Thanks for your suggestion. I did a research and I think I will try the road with the power supply. This article explains the different circuits used to limit the inrush and for my application it's to complex. Another article also describes some solutions. But still to complex. So I found the...

Update on my journey. I soldered in 470 Ohm resistors. And it doesn't work as expected... To sum up: - With diodes in place it worked for two month - With diodes and data line resistors it work for a month. The good part is, that the first leds don't get fried anymore. But now other parts of...

I tried it with the diode array. But had no luck. I used BAT 86 (Schottkydiode, 50 V, 0,2 A, DO-35). But I found an article on Adafruit, which states that there should be a data line resistor. So that's what I'm trying now. My diodes are plugable. So more testing :-)

Hi! Some remember my old posting about building a 7 segemnt crosstimer. It's working fine since then, but now I'm thinking of building version 2. I had some issuses with the first led and the power, which I try to solve in this version. I don't have a power switch or something else. I always...

You are right. I edited the part for the rounds and now everything is working fine. The thing I don't understand is, that since I have a state machine it shouldn't be doing anything with the wCurrentRound until it's in that state. That's why I thought it is not relevant. But hey, you never...

Holy Moly! You are right! I'm sorry I mixed the following lines: wRound = Serial2.parseInt(); wStation = Serial2.parseInt(); So my fault. Now my output is looking better, but still a little strange Sending Workout: W02,10,00,02,00,01,00,01 Serial data available <-- Still from my...

Hi! I have a strange problem with Serial and Serial2 on a Teensy3.1. Serial is used to output some debug messages via PC. Serial2 is connected to a bluetooth 2.0 device. Sending data over bluetooth is working fine. But sending data to the mobile results in a strange problem. I only want to...

That's it. Both are working! Thank you.

I don't need real time. It will just count down given intervals. Got myself digging into non-blocking and state machine stuff. I re-wrote the ticking code, but now I'm running into problems with my vars. I have a load, pause, preperation and pause after load cycle. Each has a minute and second...

Update Hi! Has been quite some time now and I want to give you an update. As seen on the picture, the hardware part is almost finished. But what I really underestimated is the software part... Right now I finally got bluetooth and the serial communication running, so I can send the data from...

It's done! I finished wiring the power supply up and had to ajust the led indexes (My script can't do the math ;)) And now everything is working. Next thing will be the counter, bluetooth and some kind of buzzer.

Just a quick Update on progress. I finished soldering. That was quite time consuming. But now it's ready. I also wrote a little script () to create the led map array. It's working, but it's not nice ;) I'm thinkning about excluding the colon leds into a seperate array.

Thanks! Now I got your Idea and worked it out! Btw. My little pixel problem was selfmade :-/ Looking at the LedSegmentMap array at seg3 there was a typo... Found it, after I changed the led, thinking it was damaged and the new one also didn't work. Now it works like a charm! I still needed to...

Hey guys! My hardware arrived and I started experimenting :) So far, so good. I wrote the code kind of tetsuo mentioned. But now I ran into a little problem. If I display the number 1, 4 or 6 I got wrong leds turned on. And I have no clue why. I made photos, so it's easier to understand...

Thank you ver much. That looks promising. Then I'll start working on my CrossTimer ;) Is there a difference, if I just put one led strip with 240 leds on one pin of the teensy or if I split the strip? Since the OctoWS-Lib ist using all 8 pins, I just could split it up.

Hello! I'm thinking of building a big interval timer with an rgb strip in form of a 7-segement. I would like to use the OctoWS2811 LED Library. Is it possible? I think I have to write some functions to get the right led numbers for each segement to display a number but that should it be, right?
