Introducing... the original Raspberry Pi board! Why would I be using this, you ask? Well, this week disaster struck! Some advice for anyone using a Raspberry Pi: please don't do what I did and power hardware from the Pi's GPIO pins! Unfortunately this killed off our Pi 3 B+ and I've been unable to work on it for much of this week ☹️
Thankfully somebody has loaned me this lovely antique until I can get a replacement!
The GPIO pins on the Raspberry Pi are used in my project to drive our sample turntable (a prototype of this can been seen on one of my previous posts) and hopefully also in the future a rotating carousel to store them all on! This is described a little more in that previous post but basically the rotation means we can take many pictures of the sample from different angles (tomography) and then reconstruct into a 3D model on the Pi.

Just having a bit of fun with the robot arm..!
We are using a 3D coordinate system to map out the motions of our robot arm for sample changing, and I'll be programming it in Python integrated with GDA, Diamond's Generic Data Aquisition system. Obviously typing on a keyboard is perhaps not the most useful thing the robot arm can do but we are all very excited by it!
To learn more about GDA, Diamond Light Source or my project, please check out the link in my bio and my other posts!
👨🎓 Have you ever heard about Pi number?⠀
📚 Of course, you have, think of your school times.⠀
Okay, it ain't fun, but still 😉⠀
🤓 Did you know that...⠀
🅿️ Pi, or π, is the ratio of a circle's circumference to its diameter. Because it is irrational, it can't be written as a fraction. Instead, it is an infinitely long, non-repeating number.⠀
🅿️ Did you know that the first million decimal places of Pi contains 99,959 zeros, 99,758 1s, 100,026 2s, 100,229 3s, 100,230 4s, 100,359 5s, 99,548 6s, 99,800 7s, 99,985 8s, and 100,106 9s.⠀
🅿️ Plato was one of those who got the correct value for pi: √2 + √3. But can we really find a true value of Pi?⠀
🅿️ Since 2009, we celebrate official Pi Day on 14th of March. The official celebration of Pi starts at 1:59 p.m. to make a proper 3.14159 when joint with the date.⠀
🅿️ Albert Einstein was born on Pi Day.⠀
🅿️ Pi is also mentioned in the Bible.⠀
🅿️ The mirror image of 3.14 is “PIE.”⠀
💙 Double TAP for all these fun facts!⠀

Happy #piday everyone!!! Finally getting started on the #raspberrypi version of this! The #windowspc version is kind of on its own track now which frees me up a bit to work on an all-in-one #pcb for use with a #rpi
