Texys 2.8 inch touchscreen with RasPiCamcorder - step 1

At the end of August, I bought one of Texy’s 2.8 inch 320×240 touch-screens to have a play with. I thought it’d be great if I could somehow get it working with my RasPiCamcorder. Although, at the time, you had to jump through quite a few hoops to get the drivers working, and nobody had yet done the necessary work to enable camera output to be displayed on it. Then I got busy with KickStarter and HDMIPi and it lay untouched until December. I periodically looked in on the camera section of the Raspberry Pi […more…]

HDMIPi - the 9 inch portable Hi-Definition HDMI screen for the Raspberry Pi - KickStarter

On Thursday afternoon at 15:27 I launched my first KickStarter campaign. It’s called HDMIPi, (pronounced HD My Pi). Basically, it’s a 9 inch HDMI screen with 1280×800 pixels, so it’s high-definition, but not full HD. I’ve joined forces with Cyntech for this project, as they have the experience and connections to see it through. Pimoroni will be doing the case/surround for it. Since the Pi’s fantastic GPU can handle HD, an HD screen seems desirable. But small HD screens are stupidly expensive. So, in the spirit of Pi, we thought we’d see what could be […more…]

Pi NoIR filming in the Dark - Experiment 1

After trying out the new Pi NoIR camera in a daylight comparison, it was time to test it for its main role. Apart from specialist applications in botany, etc. the “killer app” for Pi NoIR is night vision. You need an infra-red source to illuminate the target area. The only one I had to hand was an IP cam, which has a light sensor on it and ten infra-red LEDs. When it starts to get dark, the leds switch on. I’ve got another IR source on the way from Phenoptix, which I plan to dedicate […more…]

Pi NoIR filmed by RasPiCamcorder at Raspberry Pi HQ

While I was at the Raspberry Pi HQ in Cambridge last week, I thought it would be fun to shoot a little video of the new Pi NoIR camera using my RasPiCamcorder and some close-up lenses. It seemed like an unmissable opportunity. It’s a rather short video, but you should see some people you’ll recognise in it. I also tacked onto the end a quick comparison of daylight use of the Pi NoIR and RasPiCam. This shows why Sunny were a bit reluctant to release a version with no IR filter in case people tried […more…]

PiNoIR - what's it for? Comparison of RasPiCam and Pi NoIR output in daylight

The PiNoIR Raspberry Pi camera without infra-red filter is about to hit the streets. It looks like the first purchased units have shipped already. Matt “Raspberry Pi Spy” Hawkins has got one he bought from RS. I’m not quite sure what happened there, since the product isn’t officially launched yet. But no doubt others will have them soon enough. Needless to say, before it even officially hits the streets, people are arguing about what it is, what it isn’t and how the Raspberry Pi Foundation should and shouldn’t be referring to it. (What a pedantic, […more…]

Pi Noir - macro photos of the new Raspberry Pi camera board

I went to visit the Raspberry Pi Foundation in Cambridge on Friday. It was really nice to finally meet Liz and the ever-growing team. We exchanged “black boards”. I gave them samples of some prototypes I’ve been working on, and they gave me one of the new Pi NoIR camera boards with “No IR” filter. I tried it out with John (who’s been working with Gordon on solving the USB issues). It works exactly the same way as the green PiCam. The only difference is that, because there’s no infra-red filter, daytime colours look a […more…]

RasPiCamcorder software released on Github

A few people have been asking me about the RasPiCamcorder software. My original plan was to partner with a well known supplier and offer a “build your own RasPiCamcorder” kit, along with software and instructions, as a product. The software was always going to be open sourced though. But the market said NO! Many people have argued with the market and lost. I don’t intend to. There simply weren’t many takers for it. Cool though it is to be able to Dropbox your photos and videos, having neither sound nor screen seems to be enough […more…]

 How to stream vlc from a Raspberry Pi with GPIO control but without being root

Having managed to get VLC streaming from Pi Camera to Nexus 7 Android tablet working, it was only a matter of time before I wanted to stream from the RasPiCamcorder. But when I tried it, I came across an annoying problem. RPi.GPIO needs to run as root (that’s why we always use sudo for our GPIO stuff) But VLC refuses to run as root. This means you can’t run them both from the same program. There’s all sorts of clever solutions people proposed (and I wasted a lot of time unsuccessfully trying them all out) […more…]

How to use DropBox with Raspberry Pi

I wanted to be able to upload photos from my RasPiCamcorder straight to DropBox. So I did a little research and came across an absolute gem of a program called Dropbox-Uploader, by Andrea Fabrizi. A truly brilliant piece of work that gives you access to your DropBox account right from the command line. You do have to jump through a couple of hoops to get it set up (security mostly), but once you’ve done that, it’s a breeze. 1. DropBox account First of all you need a DropBox account. Hop on over to DropBox and […more…]
