Is it time for you to do a science fair project? Are you looking for ideas? You’ve come to the right place.
As one of my ‘loyal readers’ has pointed out (thanks Nick), the schematic in the MagPi has the LED in the wrong way. Be sure to connect the negative side of the LED to Ground and the positive side to GPIO25.
Wolfspec 2.0 – Spectrometry with the Raspicam
This post is a reprint of an article I wrote on my earlier website. I’ve tried to update the links and images, but may have missed a few.
I recently purchased the camera that attaches to a Raspberry Pi and thought about how one might be able to make a spectrophotometer using the camera as a ccd-like detector. This work is still in progress, but with relatively few steps, I was able to get an instrument up and running (and even calibrated – sort of).
This is a classic article which I’ve restored from a former version of my website. It has been modified from the original version.
We had a birthday party to attend recently, and it gave me an opportunity to dust off some of my cupcke recipes. It”s been a while since I”ve done some decorating, and I almost forgot how much fun it is…
If you’re a frequent visitor (and I doubt you are, because you’re not me, and I don’t think anyone really visits here unless they have to) you’ll notice that the website has been revamped again. I noticed another backdoor was opened in the previous version of the website, and I ended up taking a scorched-earth approach to solving the problem.
I also felt a need to change platforms. Joomla was too much for me. It’s not only the multiple (sadly successful) hacks, but Joomla is a bit too heavy for what I want to do here. So, I’ve decided to try WordPress. We’ll see how it goes.
Where’s the old content? I do have backups (which aren’t that easy to access, given the way Joomla does things) and once I confirm that the content is clean, I’ll start curating it and restoring useful bits here.
