Well! Its been a long time since I’ve actually blogged as I’ve been so busy! I’m now back at university (with 25 hours of contact time/week), along with vice president’ing UoN ShockSoc (https://twitter.com/Shock_Soc) and being the general secretary of BladeSoc (https://twitter.com/UoNBladeSoc), leaves little time for me to do much else! I have however been asked my one of my readers to do a quick update on the SSD1306 LCD library so here I am!
I wrote the original library a fair bit of time ago so the quality of coding isn’t amazing but hopefully it should be good enough to give people a gist of whats happening. As with everything, the LCD I’m using a is a cheapo 128×64 OLED that can be bought off eBay (http://goo.gl/0Pkvyn – Link will expire!) for ~£3. OLED Displays are so cool in the sense that they can provide crisp and even backlit images as each pixel is essentially an organic LED. This has the downside of increased current compared to conventional LCD’s but with the advantages of crisper more defined images, as an example, the Samsung range of high end phones use AMOLED displays which are designed around the whole OLED idea, giving some of the best colour representation available on phones today!
None the less, onwards with the library!
The whole sketch to test the LCD can be found on my Github. I’ve left the pin wiring as comments in the Github file! 🙂
Further on with news:
As the vice president of ShockSoc, it is up to me to choose the year long engineering project for the society! With some deep thought, I’ve decided to design an electric trike! For those who have read my about page, it is going to be quite like the one I’ve previously designed (hence, I feel its a pretty safe project for me to be able to complete by the end of the year) except there will be no welding, it will hopefully be a lot safer and will look much more professional! With the help of one of my fellow engineering friends, we’ve done some preliminary mechanical calculations to ensure the frame will be able to bear the mass of a large student, and still function correctly.
My friend is a mechanical engineer so he is quite advances in using Creo, something I’m not advanced in… at all. Regardless, the other night, we got our planning heads together and have sketched up the preliminary cad diagram:
Due to the university policy, I’m not allowed to purchase parts off eBay which increases the budget by a fair amount but I think we should still be able to do it relatively cheaply. The main expense comes from the hub motor (at the front), controller and steel frame work. Fortunately, most of the parts are available from renowned sources such as The Metal Store (http://www.themetalstore.co.uk/) and I will likely be buying the hub motor from Amazon.
Keep tuned for more ShockSoc updates!
