FP 2/3/... Modules & Wishlist meta discussion

I don’t think I understand this one. My English is not perfect but doesn’t redundant mean “not necessary”? Why would someone need such a thing?

From wikipedia:

RAID (originally redundant array of inexpensive disks, now commonly redundant array of independent disks) is a data storage virtualization technology that combines multiple physical disk drive components into a single logical unit for the purposes of data redundancy, performance improvement, or both.

It opens the way for scenarios like: One SD card dies, the other seamlessly takes over without data loss. Alternatively, two cards share data, which in theory nearly doubles the read/write speed (but one card dies, and all data is lost).
RAID requires either a hardware controller, or an implementation in software. Both require kernel drivers to handle this.

@paulakreuzer

How about an “emergency circuit”

Part of what you’re describing sounds like the equivalent of dual bios in PCs, i.e. having a failover chip in case something goes wrong. I’m not sure enough of the android boot procedure to know whether would be possible on android. You’d also need a secondary OS option, in case the problem isn’t the bootloader. Something like MSI were doing with Winki perhaps. The latter part can probably be done, but a failover bootloader likely needs hardware as part of the SoC.
For the power reserve, I think I’ve seen batteries that have a physical button on them that enables the battery to drain slightly further than it would normally allow. I wouldn’t go for a separate built-in battery.

You don’t buy the “thick soft one-piece additional plastic over-cover” ? To add more shocks protection ? If solar panels can arrive, they must be on the outer-side, so both are linked, but solar panels were just the 2nd half of my suggestion

Oh I should have known that, I even use RAID myself, but never thought about what the R and the other letters stand for. I thought @siltaar was talking about a fake micro SD slot in case someone raids/steals your phone, but that didn’t make any sense.

@Johannes

I never heard of that but you’re right! It does sound similar. :woot:

@siltaar

Instead of adding an additional cover wouldn’t it be better to make an alternative cover with (even) better shock protection (I believe the existing cover is already quite great) and maybe an integrated screen foil?

@paulakreuzer

I like that and it made me think. How about an “emergency circuit” that made it possible to start the phone with just the calling function even if all else fails (e.g. battery is [nearly] empty, you FP has a solar charger but there is not much light because you’re inside [or trapped under an avalanche], you installed an alternative OS and bricked your phone, …).Do you guys think that could be possible?

Yeah, let’s build a dump phone inside the Fairphone! On a more serious note: I very much like your idea. I could imagine two ways (without knowing anything about feasibility):

1. Make the Fairphone recovery capable of dual-boot, and have a second minimalistic OS only for emergency calls or (in case of a soft bricked phone) for calling your technician of trust.
2. Make a back cover with alphanumeric hard buttons, so you don’t need a (proper) display to do calls. Remember that the LCD consumes the most energy!

[siltaar]

Here it really looks like there’s no need for my ‘over-cover’ idea :

Adding this to the thread, and linking to the separate thread where I ask about it…

MHL. Probably not possible from what I can see of the connectors, but it would be good to know one way or the other.

MHL is little more than a party trick on Android. But if/when Ubuntu Touch comes to the Fairphone, it promises to turn your phone + mouse/monitor/keyboard into a proper computer.

Upgrade potential: MHL?

MHL and USB3 are two technologies I would very much like in a 2016 smartphone, both of which are lacking from the Fairphone 2. Fair enough, can’t have it all. But modularity is supposed to make the phone somewhat future-proof, so… what are the chances of adding either or both of these to the USB module? With MHL, what I know comes from my very disappointing Meizu MX4 Ubuntu edition. The core chipset supports MHL, which led to me finding some misleading spec sheets before buying. But you als…

[paulakreuzer]

@matthew_exon

Probably not possible […]

So I’ll put it down under “less realistic” right?

PS: Someone should probably go through the other suggestions and evaluate which are more and which are less realistic…

[johnc]

An upgraded camera module, I’m happy to accept a phone with a smaller screen, slower processor etc than other phones for the same price but it would be very good to have a camera similar to a Nexus 6p or other high end phone

[dvl]

PS: Someone should probably go through the other suggestions and evaluate which are more and which are less realistic…

stronger battery (even if it means a phone with a hump)
Sure

NFC/Wireless charging
Sure

Keyboard
I know a guy

alternative E-reader display
Sure, but complex and thus expensive. Dont count on it.

Solar Panel on the backside and/or integrated in the screen
Sure, will charge ~2% per hour, you decide whether this is enough. (in screen: no.)

programmable remote control
Sure, rx&tx

emergency button for elderly people
Sure, but not improvement from current systems

additional sensors: barometer, temperature, sonar, radiation
Sure

black-light (UV)
Sure

a waterproof built-in case/back with a built in flip-cover
Maybe from company that does this on regular basis

Charger for a spare battery.
Sure

Alternative hardware components that allow software freedom. E.g. a
i.MX6, OMAP4/5 or Allwinner chipset to allow the installation of Replicant
Very very complex.

hardware switches for phone service, camera & microphone2
Will need replacements on modules, so phone service no, camera maybe, mic yes

built in projector
No current pico projector parts available for reasonable price, so not now

MHL/USBC
USB-C port, sure. Functionality of both will depend on what is available on that connector

Hope this helps

[jftr]

Great idea. Thanks for taking up the job.

@dvl

I’m skeptical about a third-party cover being able to make a phone waterproof. Any cover would probably need to keep at least the USB connector open. It’s gonna be very hard to make the phone waterproof since this part is not waterproof already.

Last time I checked, at least all the newer external small solar panels (backpack-size) nowadays even come with regulated USB ports and sometimes even with a small powerbank. Maybe more efficient in the long run anyway.

Exactly, so developing and making a barely usable one for the phone is pointless and goes against all logic.

Yes, thanks. I updated the list.

@dvl you missed the extensible in my quote. It was an idea by @QuentinT:

@QuentinT

A big back cover with extended (multiple parts / sliders / ???) solar panels. I mean, being able to fully trust the solar pannel to recharge the phone and use it as GPS, camera and so on.

But I agree, it’s not realistically a better solution than a separate device at least not with current solar panels, so I put under “less realistic”.

[QuentinT]

Right @paulakreuzer. I’m thinking about a module like that :

So you can use it as solar pannels & as cover. But I dont know how heavy, powerfull and big this would be.

[fp1_wo_sw_updates]

@QuentinT

So you can use it as solar pannels & as cover.

The question the I have: Is it really useful to have the panel and the phone in one place? You always want the panel as much in the sun as possible (on the ground, on a pole, on your backpack/rucksack). The phone is much easier to use in the shades and in front of your face, even while charging.

But maybe I misunderstand something … you want to use the solar panel as a ‘protector case’ at the same time, right? Good, as long as it detachable, I guess.

[QuentinT]

I think the problem of 2 separate devices is the setup. It’s so easy to just put your phone on the table, on your bike or so. Setting up the phone and the solar panel is longer. Still, I don’t think the surface is big enough to power your phone…

[Lidwien]

Perhaps the Waka Waka Base 5 is something you are thinking of:

• 5,000mAh batterij, fully charged after 4- 8 uur sunlight
• Average smartphone charge: 2 x of 200 %
• 2 LED lights, maximum brightness: 40 lumen
• Super efficient 7.5 Watt solarpanel
• Proprietary Intivation SunBoost chip
• 100% recycled PC-ABS, high impact resistant

Disclaimer: I am just loving the idea of WakaWaka but I am not involved in the company.

It would be interesting if you had an alternate e-reader front screen - since the screen is so easy to remove you could clip the one out and slide the other in for long journeys, and set it to “Reading Mode” so it behaves mostly like a kindle.

Loving this idea. Will totally depend on the amount and details of the documentation FP will provide. Also, it will not be cheap.

But very very cool idea!
