Since the battery is outside the case I simply disconnect it and then I recharge it with my SparkFun Blynk board.

You have to put the libraries in /Documents/Arduino/libraries. Then you upload the code to the arduino. There is no problem to use 1/4 watts resistor since the current that goes through is couple mA. :)

Hi ! Thanks, will send the exact dimensions as soon as I get home (probably in 1 hour). :)

Yes, it is possible !

Whoah ! Nice work jianju, keep goin', by the way if you need more dimensional data about the rest of the components let me know ! :)

I took the screenshot on Ubuntu linux.

I usually go to the nearest electronic store and buy USB cables, they have 4 colored wires(red, black, green and white) that are perfect for small electronics like my watch.

I see, yes its possible but I decided use RTC cause it will keep time even when the whole watch is powered down. I was thinking to use one ESP8266 to make better watch, I would program it to get time from the net and also to sleep when I don't need it and when I need to know what time it is, I press button to wake it up. The whole watch would be powered directly from the battery.If I had used another RTC like DS3231 I would directly powered from the battery cause DS3231 uses 3v to run.By the way the Pro mini I use can run on both 3.3v and 5v.

First why, cause you saw one instructable, and you already lost hope. There are other much interesting than mine. Second change your profile pic, you look like a pedophile.

Most 2.5'' HDDs require over 500 mA, and most, maybe all new, devices can provide that current trough the USB ports and yes most 3.5'' require higher than 500 mA current, something I missed to add to my instructable. (No problem, still I could understand you !) :)

I think It should work, go ahead and try !

Yeah, I saw that they are sold for over 3$, Its just the board that adapts the SATA/IDE to USB.

Thank you !

As we know, batteries have capacity and Capacity = Current * Time (C = I*t).In my case PIXIE in "watch mode" consumes 60 mAh and my battery has 650mAh capacity, which means that the battery will hold up to ~ 13 hours.

The board is available with the enclosure, but I think they are sold separately as well for ~ 5$.

Thank you and you're welcome !

Yes, it is completely safe !

Mhm....

Can you provide a photo of your hardware setup ?

Is it possible to increase the Current to max 2 Amps ?

If I use a 100k resistors I should be able to measure max 60 Volts and 6 Amp Current

Hi deba168 !What is the max Voltage and Current measure ? What is the limit ?

Definitly it's the best one ! :0

Nicely done ! It looks amazing, I love how you did it !

I like what you did, nice work !

Thats a good idea I will put it in `ible !
