Re: What are the issues or using Python on Windows 7

Raspberry specific modules won't be available, but IDEs can often use Python envs over network (like PyCharm) which will give autocompletion or code browsing. With some deployment scripts (or SSHFS alike solution) good IDEs will also be able to push and execute the code on RPi when needed.

Re: Looking for keyboard

There is no need for special drivers. I use wireless (USB dongle) Rapoo keyboard (full size, not tablet mini version) and it just works like any other.

Re: sshfs for Windows

There is no good SSHFS solution on Windows, as this feature is quite Linux-specific. You can check https://code.google.com/p/win-sshfs/ but it looks like it's not actively developed any more. If that won't work you will have to look for other alternatives.

Re: sshfs for Windows

To big differences between systems. You can use Linux in a virtual machine (or native)... or use some SFTP code deployment script, or use something that is a microcontroler and not a second computer that can't be as cool in "remote" programming on a master PC. :twisted:

There is no hope. It can't - that's the shortest answer.

Maybe the SD card had bad random I/O performance or other processes were doing I/O or CPU work. That would slow down SQLite a lot.

Re: What is the Rolling Shutter Speed?

You may look for Point Grey Firefly camera - a lot of them were sold on ebay very cheaply (and maybe they are still there ) - for a webcam price while being USB2 basic mono machine vision camera with a global shutter CMOS. PGR has FlyCap for ARM Linux so it ought to work.

Re: Rpi Camera vs. PiNoir: Normal Colors + Infrared?

Starting from around 680-690 nm and up you have wavelengths invisible to human eye. Most suited to use that infrared band are monochrome sensors as all pixels would be sensitive to it. Color sensors have limited IR sensitivity, but still they do respond to it.

Re: Mysql getting slow

Databases like MySQL like to use RAM which is limited on Raspberry Pi. Using SQLite could help, and if the SD card is good at read/writes it could provide acceptable query speeds (but you have to test that).

Re: compute module, the embeddable device

Hard to tell if there is a point for yet another "prototyping" baseboard for the RPI COM.

And the market of end-users/hackers is rather saturated with Raspberries, so it would be hard to se...
