Re: Best Place to buy Electronics?

In UK CPC/Farnell or RS are the big component suppliers but there are lots of smaller suppliers and of course there is ebay items from china for small modules that are very good value but take a while to arrive Simon Unfortunately, my experience with Chinese suppliers selling via eBay is very mixed...

Re: Best Place to buy Electronics?

Fun to read this thread..."Radio Shaft"..... :D :D :D Back in the "good old days" (20+ years back), they had some decent (not great) component parts in stock at a fairly reasonable (not great) price. Even 10 years ago, they had a decent (not great) web-based, mail-order option available. Prices were...

Re: What IDE to use?

IDLE, I believe, is the default IDE for Python running on the Pi. Geany was recommended to me as a lightweight, all-purpose IDE/editor that runs on the Pi. Supports both Python and C/C++. I've been very satisfied with it for small projects. http://www.geany.org/ I believe Geany is in the Raspbian di...

Re: Low-level (Linux framebuffer) graphics programming tutor

This thread is excellent. Thank you to the OP for all of your hard work! And to those who were asking about SDL on the Pi, you might want to take a peek at https://github.com/vanfanel/SDL12-kms-dispmanx#readme That's is a Raspberry Pi-optimized backend for SDL 1.2, using the "dispmanx" approach.

Re: Cross compiling SDL (succesful)

Thanks for posting!

I've played with SDL a little on the PC using the Linux before and it is very useful.
Very simple and direct.

I will have to look into it on the Pi now.

Appreciate all of the details!

Re: OpenGL ES tutorials?

One more idea, if you are TOTAL newbie to Open GL in general, it's worth reading the first few chapters of this book. "OpenGL SuperBible: Comprehensive Tutorial and Reference (5th Edition)" by Richard Write, et al. , Pearson Education (publisher). It's the "official" teaching guide to Open GL and it...

Re: OpenGL ES tutorials?

Somewhat of a beginner/newbie with OpenGL ES myself. (Actually somewhat familiar with ancient OpenGL 1.x...but never was really fluent.) OpenGL ES 2.0, which is where you want to be working if you're starting from scratch, is hugely different from OpenGL ES 1.x and I have not found that many good "t...

Re: Shipping Cost

Recently ordered my Raspberry Pi from MCM and paid about $15 in shipping for regular UPS ground delivery. That was the shipping cost for three items (the Pi, a case and a USB wifi dongle). Compared to some "high-volume discount computer resellers", the shipping seemed a little bit high. But compared...

Re: Advice on Genesys Logic IC's

I do no know what the status of the company is, however, I am using an unpowered 4-port USB 2.0 hub on my Raspberry Pi Model B (512MB). It seems to work OK. I only have a keyboard and mouse plugged into it, so it does not draw much current. When I do a "lsusb -v" at the Linux command prompt, I get t...

Re: Which Language to Learn?

Depends on what you ultimately want to do with your programming skills. If you want to do systems-level programs, it never hurts to learn C. You will have to eventually, so why not start there? Some people have jumped right into C++, which is OK, too. But I see it as an add-on to C, more than a stan...

Apparently, several folks have been successful doing this. Just Google "Raspberry Pi HDMI to LVDS adapter" and you will get a lot of links, including severa...

I had read the instructions for building Qt5 from scratch for the Pi and it sounded a bit daunting! I will do some reading and pull it down the pre-built one....
