Re: New 8MP Camera - Q&A thread

Impressed by your testing methods! Curious what your setup looks like. Do you have just one test chart, and manually re-angled the camera to re-frame the image at each of the 20 ROI segments along the image diagonal? Then repeated that for each of 16 distances? Just one test chart. The previous cha...

Re: New 8MP Camera - Q&A thread

New test and odd results. tl;dr (i.e. Executive summary): Noir V2.1 angular resolution measured diagonally. Left is near, red is bad. ready.gif New test chart was made. No images were actually obtained, but instead the preview window was used to measure resolution. Observations were made by turning ...

Re: New 8MP Camera - Q&A thread

New day, new tests. New results! This time we look at borders, left and right. There are 4 images, which show that resolution is better near the unit and gets worse further away. The near resolution is so good that couple of images from center area were re-acquired, but those resulted the same findi...

Re: New 8MP Camera - Q&A thread

These camera modules have finally reached the very rudimentary testing facilities of 9aed! Naturally some tests have been made. Contrary to quite popular opinion, the module under test (green V2.1) is not nearsighted. In fact, it starts to resolve around 45 cm and behaves fairly linearly at least up...

Re: New Display - Cursor Jumps and Clicks all over the place

We're going to try some shielding with aluminum foil and see if that improves things. Inspired by that, the local display has been overly wrapped in nice foil packaging. I have even tried to run the device under cover. Result: Capacitive sensors have a hard time sensing anything properly through ea...

Re: A new camera coming May 20th?

Interesting to see the the v2 camera likely will be cheaper :-) If it were to follow general digital technology model, it should be even cheaper. Assumptions: current prices instead of original no inflation comparison: only processing power or pixels Akane got it right in https://www.raspberrypi.or...

Re: A new camera coming May 20th?

Yes, Virginia, there is a Raspberry Pi Camera Module V2. Component supply system is a long, complex and utterly convoluted system. There is a multitude of details. At one end is management, then design, manufacture, logistics, distribution, re-sellers, a myriad large and not-so-large details. Theref...

Re: New Display - Cursor Jumps and Clicks all over the place

This behaviour still seems to haunt the display. The device that arrived here exhibits quite similar state of non-functionality. Things tried so far: different Raspberry Pi models: B+, B2, B3 and for the last tests (below) A+, different power supply configurations and power supplies. All tests were ...

Seems to be Google is quite good at this too. Product names COULD be something like Raspberry Pi PiNoir Camera Module V2 Raspberry Pi PiNoir Camera V2 and product code for at least the PiNoir at RS MIGHT be 913-2673, according to search, whereas Allied numbers match 70812916 and 70812917.

Re: A new camera coming May 20th?

Just to make the popcorn worth it... A German reseller seems to have dropped NoIR completely. Not "out of stock", not "limited amount in stock", but completely vanished. Standard camera seems to have a "limited amount" status. RS associates NoIR with a backorder button And then, what is "Raspberry P...

Re: Fisheye / wide-angle lens in Lidl Mon 29 Sept

Reichelt elektronik seems to have a whole wide angle camera module in stock, a couple of EUR over standard version. However, it seems to be a bit dubious operation. It is clearly marketed with name "Raspberry Pi HD-Wide-Angle Camera Module", but Datenblatt (just half of it is auf Deutsch) tells "spe...

Re: raspistill - skipping frames

Which frame rate does the automatic frame rate chose for "-ss 6000000"? The actual exposure is not the full 6000000µs but 5969487µs, so there could be a small difference which could produce the observed behaviour. During last 24 hours these 2 systems have produced around 12 000 images and 4600 "mma...

Re: raspistill - skipping frames

Re: raspistill - skipping frames

Burst mode was a huge improvement when it was introduced, just as long exposure itself was. Without -bm the command captures frames 1, 5, 9, 13, 17, 21, 26, 30, 34, 38, 42 and so on, averaging an image every 22 seconds or so. There is enough time between frames here for the chip to cycle through a m...

Tonight I ran more tests and they confirm the finding. Testing environment tonight consists on writing on /run/shm. A shell script is movin...
