... Regarding a controller board. If I'm not mistaken, @kite's board will also be driving the lcd through the Pi's GPIOs which is done through SPI. Without the board, one can still directly connect the lcd pins to the Pi. Kite's board will make it easier for everyone. Just to correct you, but my bo...

... So pictures are OK, as good as my phone seems to want to take, but if you need numbers or other pictures, let me know and I will break out the real camera (needs a charge, so cell pics is all I got for now). These are great, could you please confirm that the 10 resistors in the bottom right cor...

They seem to be interchangeable just looking at the ribbon cable pinout given in each datasheet, @kite could you confirm this? Yep they have the same pinout! So both are interchangeable. EDIT: I have been looking at the datasheet and need to do some gamma reference voltages, the datasheet isn't ove...

Hi guys, I did a little more inspecting on images, and I have come to the conclusion that the LCD is NOT using 'DPI' but instead is using 'DSI' .. DPI is open on the Pi, DSI is closed source (for now).. so it doesn't look possible to reuse the existing LCD.. Here is the evidence. You can see that th...

The author of that blog is recommending letting the least significant bit lines on each color channel float to reduce pin usage. I initially thought that would compress the color range (making the colors look flat), but it's only 7/255 from full white (black? I should look up if a 0->1 transition i...

Hey just seen this :) read through my whole thread on my project you linked, I did go into detail and offered links to my sources so far! Don't forget the Pi only has 28GPIOS, the rest are gnd and power (so 20 pins on gpio leaves you 8 pins for other things). I do plan to make a separate thread or s...

I have in my possession the: 15mm 17mm 30mm When running at 2.5v they are all quiet, anything lower than 2v and they emit a loud BUZZ sound.. it's strange that going above 2v makes them quieter! Pi heatsinks are typically ~15mm square, the advantage of these fans is that they are lateral 'blowers' s...

I'm surprised no one here has any experience with serial (spi) displays... They're really not recommended as they have terrible redraw and frame rate, you'd be better off with composite as at least it would be smooth rather than horrible. There are loads of examples from Adafruit, this forum won't ...

The cam connector has a number of shorts (clean up with a soldering iron) and the two inductors at the top left are damaged, which may be a cause (they can still work but unknown, as long as the wire isn't damaged). Use a multimeter to probe around, if you probe all the big capacitors they will eith...

Charging at 1A means that for every hour it will put in 1000mAh of charge, 2500mAh should take 2.5hrs in theory.. The way LiPos charge means that towards the end the current drops, so it may actually take a bit longer towards to end as the current drops.. when current hits a set figure (50mA?) the b...
