@crispyoz is there a specific reason you have calculated 15mA drive for the LEDs?
A lot of first timers look at the 20mA current ratings for a LED, calculate the resistance for it, power it up and wonder why its lighting the whole room!
The reason I ask is because I have found, in practice, with currently efficient LEDs you can get an appreciable light output with a mere 5mA or even less. If you reduced the current to each LED to, say, 4mA I'm sure that an 8mA draw from each GPIO pin is then quite do-able without releasing the magic blue smoke.
If you experiment with a 3.3v supply and some resistors you can find a point at which the LED is bright enough whilst drawing minimal current.

@György-Farkas err for info the item you pointed to is a 5v device - this is a 3.3v system. Would it work on 3.3v?
The protocol is messy for driving those "clever LEDs" - might be more trouble that it is worth for the task required.

@Robert-Jensen 1v? Not quite there. Typical forward voltage of lowest - Red LED - is 1.8v so using two in series would be 3.6v which is just a tad short of the 3.3v available supply rail. Are you mixing it up with the forward drop of a typical silicon rectifier or transistor junction (0.6v)?

I got my Omega2pro on Friday and had the same problem but not checking here first (not been here for a long while) I emailed Lazar who gave me some pointers and I ended up downloading the b211 BIN file from the repository and after copying the BIN file to /tmp used the manual update with file method. I noticed versions b212 and b213 were on the repository but "oupgrade check" was happy that b211 was the latest?

I did hit a massive snag - I was using Firefox on an iMac "connected" to the Onion at 192.168.3.1 and using the busybox terminal program on the Onion itself. Problem was I couldn't type the dash symbol (between the zero and equals keys) - the key worked everywhere else except in busybox. Tried a wired keyboard on the iMac and the dash key still didn't work. Curiously the minus key on the number cluster of my wired keyboard did work allowing me to type the BIN file's name properly.

Anyone else found something as daft as that?
