Re: SD Card losing changes after reboot.

Aha thanks to you both! I had no idea this was a possible failure mode. I've had several cards go bad on me before and I was left to pick out the important bits with a hex editor as the filesystem was mostly unreadable :) So I'm lucky with this way of failing. This pi has been working pretty well fo...

SD Card losing changes after reboot.

Today I finally figured out why some weird things have been happening to one of my camera Pi's (unfortunately I'm nowhere near it). Every time I reboot the thing, all changes since December 2016 are lost. It's super weird. I can write to a file, read it back and it works just fine. (Though possibly ...

Re: Guide: Chromium 51 on Raspbian Jessie

Look at the first post and there is a link to an experimental build for Chromium. You need a separate patch to get it to compile for ARMv6. If that works mostly, I may replace this version with that. Ah, nice! I hadn't spotted that. I'll try that also. Thanks for your work on it! Strange that a pat...

... kweb has all these annoying control bars. This is nonsense. kweb has supported kiosk mode since version 1.0, which means: no control elements and no window elements at all.

Is there no pi 1 build for Chromium anywhere?? I thought this pi I'm working on was a Pi 2, lol... Guess I'm out of those. It turned out to be a B+ It's just annoying because Chrome has such an excellent kiosk mode that just shows the web page and nothing else at all, kweb has all these annoying con...

Re: Motion - MMAL camera

Thanks Lowflyer! I just installed your branch on jessie, it works great! I just can't use resolutions higher than 640x480 (using the width/height params). I tried using 1296x972 which is a nice full-FOV camera mode, but I get: mmal: mmal_vc_component_enable: failed to enable component: ENOSPC Segmen...

Any plans to lift the '1 per customer' limit on Pi Zero?

Just wondering if there are any plans to lift this '1 per customer' limit. I give classes at work every few months as part of an "after hours" hacker/maker programme and the pi zero is great for this, cheap enough to simply hand out so people can bring their projects home. It's a total mess having t...

Re: Sleep Mode - and or turn off backlight?

I don't think the comparison with the polyfuse issue is a fair one. They're easily bypassed and I still use one every day with the USB ports hard wired to the input. The PSU I use has fuses too anyway. Nor is the comparison with the 256MB model as that was an explicitly stated spec. For the backligh...

Re: Sleep Mode - and or turn off backlight?

Yes, there has been a point release for the DSI display hardware. No, you can't modify a v1.0 board to be a v1.1 board. There was an obscure problem found with the backlight power supply (takes 5v input and boosts to a current-limited ~18V or so) that when driven at the PWM frequency we programmed ...

Yeah a gel filter foil should do the job in the mean time. I wanted to make a cool alarm clock with the option of looking at live view of the raspberry cams I have.

Re: Sleep Mode - and or turn off backlight?

The lack of brightness adjustment is really disappointing. I don't understand why it's not possible, as there is a PWM controller on the display according to Gordon's comments? I could imagine it interferes with the touch controller but then it'd still be great to have it for applications where touc...

Re: Sleep Mode - and or turn off backlight?

I'd also really love to have dimming - I assume this is still planned?

The display is very bright for normal use cases, though it's great that it can go so bright I would need to dim it for most uses.

No. It's an I2C touchscreen. Thanks for confirming! That's great! Good to keep those USBs free. By the way, I was looking up the schematic, it looks like Model B+ does have I2C on the DSI connector (pins 11 and 12), I assume for Model A/B we could simply hook up the touchscreen to the I2C on the GP...

It's REALLY difficult to predict this sort of thing, and it's better to make too few when you don't have the unlimited cash piles that bigger companies have.

You're right, it works totally fine with a fresh raspbian image! Would you know what could have caused this to break?

Checked it out, they both have the same RG2 chip by the looks of it but the markings are different. The first line is 17-33G in both cases. But the second line is different. The Model A one is marked RQB44, the Model B one is RQC18. Strange enough I can't find any reference to these markings in the ...
