I tried EUC World for the first time

[Mike Sacristan]

As an iOS user I have been using Darknessbot. Yesterday I tried EUC World for the first time. My friend Thomas lent me an Android and a pebble watch.
I set the (voltage dependant on) alarms to:

64kmh - 100% battery and below
60kmh - 80% battery and below
56kmh - 50% battery and below

This coincides pretty much with the 5 beeps on the Nik+ except realistically the wheel will beep at 62.xkmh near the top of the battery.
So at any point if I hear an alarm it will be within the limits of the wheel and in my favour.
I ride a 2664Wh 1Radwerkstatt Nik+ with Samsung 50e cells in a 24s6p configuration so I don't worry much about the performance of the wheel. Especially with my riding weight of 64kg.

I also set the temperature alarm to 60C since the fan on my Nik is not working properly. I opened the Nik last night and it is simply not spinning up but jerking when it reaches +38C. I can spin it fast with my finger and then it will spin up and keep spinning until it goes down to ~35C.

If I wanted to I could be a bit more aggressive and set 70 / 64 / 60 but I don't ride with gear and I refuse to fall off at high speed.
My friend Tobias did get his Loomo Nik+ (2660Wh) up to 73kmh the other day though. A long road with a slight decline. He weighs 100kg with gear.
Still... he is him and I am me.

I set EUC world to play the alarms through the Nik+ speaker and also to vibrate on the pebble watch.
I disabled all other voice prompts except for wheel connection/disconnection as it is a good way to ensure that the phone is using my Nik speaker as it's audio output device.

The alarms worked as expected and could easily be heard. The alarms are meant for me to slow down so I make sure the sound is loud and annoying as hell.
The temperature alarm also triggered at 60C while I was doing some crazy off-roading in the forest. I raised it to 63C and finished my trail.

All in all it worked very nicely and the only thing I could wish for was having a feature similar to the latest Darknessbot addition which is a single smart alarm with a 20% speed/battery reduction.

This works nicely as it pretty much follows the speed reduction of Gotway wheels.
Then one can set a single alarm to 64kmh and as the wheel goes down in battery/voltage the alarm will also go down.
Of course there are limitations such as strong winds and inclines but we don't usually ride uphill in strong winds like donkeys where we prematurely hit the 5 beeps at 55kmh and full battery.

Is there anything I missed in my config or is the voltage dependant alarm such that it allows three settings and that's it?
I would have liked to be limited to around 52kmh at 20% battery as well. Although somewhere around there voltage beeps will start at high speed anyway. But you know... vibration alarm. Because you can't always hear beeps in noisy environments. Although once could set a low battery alarm and have fun determining which alarm is which.

All in all great app and although I have not used it I have seen the online logging / tour tracking with the lovely maps, graphs and data.

Also a last note on the the pebble watch... looking at my wrist while riding to view speed was distracting and an accident waiting to happen... so I would merely use it as a tool for vibration on my wrist and then not even use the external audio alarms (unless I wanted to blast and sound like an idiot).

@Mike Sacristan thank you for your short review. It's especially important for me as a developer as you're iOS user so you have different habits. Adaptive alarms are now being developed. I don't know how exactly DB alarm works, but I suspect that idea is to get alarm that adopts to battery and riding conditions.

Thanks Seba! I really appreciate your work and I have been following your work on EUC World (olden Wheel Log) for a long time and always suggest to my Android friends that they use it.

The Smart Alarms on DB seem to simply be a % calculation based on current battery and speed.

So for instance if I choose 64kmh as the value for the smart alarm I would expect the below.
The 5 beeps kmh column is not really the 5 beeps for the Gotway Nikola Plus but it does sort of coincide quite well.
The 50% battery value and 5 beeps would more likely be 56kmh.
So the table below is done with a formula speed * 100%, speed * 98%, etc down to 80% which would be the lowest value at 0% battery.

It is purely based on state of charge as the determining factor. I don't see how any other variable such as terrain, incline, etc can be accounted for and I think it is good enough. I go into it a bit more on the other Darknessbot smart alarm thread that I made.

Nikola Plus
Battery	Smart Alarm / ~5 beeps
100%	64
90%	62,72
80%	61,44
70%	60,16
60%	58,88
50%	57,6
40%	56,32
30%	55,04
20%	53,76
10%	52,48
0%	51,4304
