I added a LM35 temperature sensor to the unit measuring the water level in my main tanks. After a mild calibration issue (shown above) it seems to be reading very close to the actual temperature 🙂 I find it amazing how much I am enjoying having this data. Very silly 🙂

Funky Clock 2.0
Here is Funky Clock 2.0, well the processor board anyway. I have several PIC18F452 in the PLCC package, so I decided to see if I could get that working. My forth is running on it and I am implementing a new UI for the clock allowing the time to be set using a really cool …
More on the Funky Clock
I had another one of the LED arrays around the place and decided to see if I could drive it directly from the PIC port pins. It seems I can, and the results are much better than my much more complicated previous setup. Of course it uses up almost all of the PIC18F4550’s port pins. …
The funky clock in action
Here is a picture of the clock running. It is showing that the time is 2:12pm 🙂
The Funky Clock
We have a problem in our house. The youngest has a habit of waking the whole house at a time that is not pleasing to the rest of us. We put a clock in his room, but that didn’t help much because the monster child can’t read yet. As with everything I decided a technological …
Bob Lives!
After a couple of false starts with dead voltage regulators, Bob (my daughter named it) the PIC based ethernet device lives in a more permanent incarnation. Bob is made from bits and pieces I had around the place (I now have several very dead network hubs). The budget for the project was zero 😉 My …
What I’ve been up to lately
I’ve been really busy recently and have not had much time to work on my side projects. One that I’ve been working on off and on for some time is a networked PIC micro-controller. This morning I finally got it responding to ICMP echo request (ping) 🙂 The next thing I need to do is …
Some tinkering I’ve been up to recently
I’m working on building a system to measure the water level in my rain water tanks. Finally today I’ve managed to get my hardware all working, and now I need to build the physical measurement device. Originally I was going to use ultra-sound to measure the depth of the water but I decided that was …
