You may recall that about a year ago I built a frequency counter based on an FPGA and an Android user interface. I called it Nanocounter and you can read about it here if you haven’t already done so. One of the basic requirements for building a frequency counter is the ability to...

You may have already read my writeup about my first experience with laser cutting and the case that I produced for my reflow oven controller. If not then you can always get up to speed by clicking here. Creating a design for laser cutting involves laying out the different pieces into a...
Nanocounter is an accurate frequency counter using an FPGA, STM32 and a bluetooth android app

Here we have a good example of how a requirement for a simple tool spirals out of control and spawns a project that takes months to complete and ends up dwarfing the project that it was originally expected to facilitate. You see, some time ago I was fiddling around with a project, something to do with data logging, probably, I’ve actually forgotten what I was up to. Said project would have used an MCU to acquire and timestamp data over an extended period of time and I quickly realised that the oscillators and quartz crystals used to generate the clock tree inside an MCU are not accurate enough to track wall-clock time over extended...
