Blinking Red Light Of Death
-
@Efriim Step down? I still have to study up on the fundamentals of electricity so I don't know any of these terms
-
@taiJones00 I mistyped the measurement over time. The 1000c can convert 3.7V xxxxmAh battery to 5V 1000mA-2500mA current.
The battery while depleted may only give 3.2V so yeah charging it for a while with the battery connected may work.
The 3.7V to 5V that the Pi requires is called a step-up conversion. A 9V to 5V would be called a step-down.
-
@Efriim I'm going to try plugging the battery and the power adapter in at the same time now. Fingers crossed. I'll also try to decipher what you just said while the battery's charging
-
I didn't learn very much in electricity, mAh (Milliamp Hours) is used for the
capacitancecapacity as it is an Amperage over time.Volts and Watts and Amps and Impedance all with conversions I can not remember any of the little that I learned.
The power adapter(charger) is plugged into the powerboost which has the battery and pi attached right?
And the charger you are using, does it output 5V 2.5A? -
@Efriim Sure is. So i'm dumb. I had the fear that I would send too much electricity to my components and damage them if I had both things plugged in. But I just plugged them both in and I have a yellow light in the charging area and a flashing red light in the low power area (I guess to reinforce that it's charging). We'll find out soon if this will work.
The battery is 3.7 V at 2500 mAh. This is the one the pigrrl 2 official tutorial said to use and it's the one that came with my pigrrl 2 kit. Should I use 5 V instead for the pi 3 b+?

If you unplug the wall charger there on the head of it is a label and somewhere it will read something likeInput : AC 110V 7W Output : DC 4.6V 900mAsometimes they are impossible to read labels.
I had the overlooked that you used this charger to do the initial installation it should work fine.
Yes 5.1V and 2.5A is nominal.It looks like the thing was designed with the battery in mind, but since it is a 3B+ it will use more amps and so doing a step-up conversion from 3.7 to 5V ~+variable amperage its probably going to be everything this battery has got.
-
@Efriim ...What kind of cantanese debockary is on this charger? Anyway, it's
output: 5.1 V and 2.5 mAh -
@taiJones00
I don't want to mislead you though, I gleaned a lot of misinformation from what I read on all this in only a couple hours. If that battery doesn't work, I still don't know for certain that a different battery will work. I wouldn't try the 9V yet, because even though it is being converted, 9V is too much for a pi and could damage it. -
@Efriim Well here's the thing. The very first time I hooked everything up, the power LED was blue and blue means it's working. Meaning, I probably just have a low battery
Yeah the last thing I want is to damage a pi. I have like 3 other projects to make for this reverse career fair and lest I waste $30 from a silly mistake
-
@Efriim This is actually pretty funny. I like that your profile picture is of an xbox 360 given the title of this post
-
@taiJones00 I was looking for a picture to use in the retroarch-assets on my computer and the idea that raspberry pi succeeded the xbox360 made me laugh. Because of pi, like circles.
-
@Efriim Ah! I get it!
-
@taiJones00
They definitely have a penchant for red rings of death. How about yours? Is the battery working now? -
@Efriim Interesting. The light was blue for like 1 second and now it's back to blinking red. My guess is once I leave it be for about an hour, it should be working
Mounting my components to the case in the meantime

@taiJones00
It looks like my previous figures were off, and the powerboost can only push 1.8Amps not 2.5Amps.1.8 might be like the minimum requirement for the RPI3B+ with a Screen attached, I'm sorry but I just don't think it is enough, and if it was then it would likely encounter problems as soon as the wifi and bluetooth turned on. Which may be why it was blue for only a second.
A different battery probably wouldn't help here as it is limited to the powerboost module. And the 9V battery is probably just a bad idea, as I couldn't find that reference.
I think the Pi2 is a better choice because all though you lose the wireless capabilites it will run reliably without the need for a fan because it uses less power.
-
@Efriim I see. I've got a pi 2 on my desk as well. I'll try that one if the pi 3 b+ doesn't work within the next 2 hours
@taiJones00 Can you post the link that says the pi 3 b+s power requirements?

M'hmm I didn't read the benchmarks before. -
@Efriim It's alive! You beautiful person you fixed it! Now i've just got to figure out how long the battery will last for and how to tell when it's at full charge
Now we know that a 3 b+ can indeed be powered with a powerboost 1000c

The screens use 100mA according to this source, there may be hope I guess.Maybe I was completely wrong, about 1.8A capabilities seeing as the other forums read they only get 1A and how 940mA+100mA sort of fits into its gap.
...oh, yay!
In that case, I think it could possiblly benefit from small modifications in the OS as well as possibly a 4.2V battery for reliability.

@Efriim Yep. I'll handle the rest of the research. You've done more than enough. Thanks bud
