Still kickin’ and alive

Like many of my posts, I simply update for the sake of updating. That’s fine as far as I’m concerned. A lot has happened since my last update. Been to Japan, designed a bit of stuff and just have been simply living. Here are a few things I’ve been working on…

This is a gage I designed and is now going all over the place.
This is a prototype master I am working on which will have motion control.

So, with that. I finally took the trip I’ve been wanting to go on for 20 years, to Japan. Now, I’m not a real weeaboo or anything but I’ve always been fascinated by the notion of such a large dense city such as Tokyo and so, with my girlfriend, we went to Tokyo for almost two weeks. It was absolutely amazing!

All in all, I’ve been enjoying my days, playing Rust and just plugging away.

It’s been 4 years!

Yay! this site has been around and updated semi-regularly for four years now. Having just paid the bill for another 2 years, hopefully it’ll be around for a while longer.

Looking back through this site I can see some of the things I’ve worked on and recall the state of my life at each of those times. I’ve gone through three jobs and one period of pseudo-unemployement. Some tough times and some good ones. I’ve learned a lot both professionally and personally.

Here’s to another 4 years of half-finished but fun projects. 🙂

Viscometer and Graphing

Now that I’ve got the new board working, I’ve been programming all of the pertinant functions back into the chip. This time I’ve redesigned them to be a little more modular and useful in the long term. As was mentioned in the post a while back, I made a new board and I’ve come to realise that the RS-485 Port is wrong. It has 2 connectors when it requires 3. A-B-Ground. Sigh!

Anyways, I’ve been running tests with the viscometer and everything is working great so far. I’ve got the temperature sensors working and the conditioning of them with OP-amps has worked like a charm. Though I find that the read value from the ADC is pretty jumpy.

Anyways, as reference, here some photos.

Also, the linearity test went well. Better than I initially expected.

One can notice that there are some burps along the graph but for the most part, it’s fairly linear as far as I’m concerned.
