As with nearly all cool electronic devices that I buy, this one too came from the foreign lands and was off eBay (http://goo.gl/jbcKE6 – Link will expire as with all eBay links)! One of the features that I’ve wanted to have in my watch that I’d actually find really useful is the ability to have […]
After much contemplation, I decided to rewrite the original ILI9163 library that I was using for the LCD. Fortunately, the LCD manual was much easier than I thought to read (http://goo.gl/CNVU8V), so tonight, I went about rewriting the whole LCD driver. I didn’t include any of the gamma correction curves as that would require a […]
So today, I woke up at the fresh time of 12:00am after some late night programming last night. I knew that my RS order should have arrived today and it did! This order had all the parts for Watch 2 in, along with the regulator I’ve used for Watch 1 (a pesky overpriced buck regulator […]
After doing a bit more research into homemade smart watches, I came across this brilliant forum article (http://goo.gl/7mI1Dm). This guys watch is utterly amazing and uses a memory LCD. These LCD’s are quite out of my price range at ~£14 each! So after another eBay search, I found a total 1.44″ gem (http://goo.gl/3Tfg7e Link will […]
The 74HC595 (http://goo.gl/J9ILXZ) is a great chip for expanding output only GPIO and is normally really cheap. Normally, you bit bang an SPI like interface to send data to it but I decided to test whether it actually works using an SPI peripheral. With my trusty STM32F0 Discovery board and my good ol’ oscilloscope, I can […]
So as my favourite form of exam (or general) procrastination, I’ve been designing a new smartwatch! This one is based on the new STM32 range and will include a TSSOP (http://goo.gl/TAUKS8) microcontroller instead of a pesky QFP (http://goo.gl/ccKwXR), they’re not particularly different other than the TSSOP package doesn’t have pins on all 4 sides. I’ve […]
One of my original sources of inspiration was from an awesome youtuber’s product (Dave Jones and his μWatch – Youtube: http://goo.gl/OjkGjg, the μWatch itself: http://www.calcwatch.com/index.html). This guy is absolutely brilliant and some of his youtube video’s are utterly hilarious! I’ve got him to thank for his brilliant video on product design on helping me design both the newer versions […]
Its been a long time since I last did an update about this but today was a great day for progress! I gave it a bit of a rest because my design was a bit dodgy and I forgot to bring out the SWO pin (PB3) but after more in depth research, it turns out […]
As some of you might know, one of my main most favourite hobbies ever is playing bass! When bass playing and electronics mix, the end result is generally either the Phobass or bass effects pedals! I had previously made many pedals in the past and two were consistent additions to my pedal board but stupidly, […]
It seems that life is most definitely on my side today. Apart from a couple of burns and an hour or two of complete utter frustration, I can happily announce that around 95% of Phobass IV Mk2 works! Slightly stupidly, I sent off for the new PCB a bit early (before I’d properly had a […]
