Lately I was playing around with a kit I had bought from ICStation: MAX7219 Dot Matrix Module Control Display DIY kit. I liked it and bought it because it is compact, small and cheap. I got 4 pieces a couple of months ago, and soldered them the same day I got them! Other obligations took my mind off them and […]
Hey, it’s already 2015! As 2014 was reaching to its end, I was getting more and more busy, like all the things left behind the hole year were coming on to me. Like Everything wanted to pass an important milestone and Everything was looking to me for a helping hand. As for me, I was mostly spending time with my […]
According to this EDN article, things are happening in the Internet of Things field. Especially interesting the part about LoRa internals unveiled. I think I should have a look at it first chance I get. EDN – Opening up the IoT data flood gates: Semtech/IBM put LoRa spec public.
I had some sample boards made. They have been ready for a few days now, but I have had no time to deal with them, I still don’t. I hope next week I will have them populated, and then the hardest part will start: I will need a lot of free time to tackle the software… To be continued… […]
You have probably heard of the term “embedded systems“. There are a few hardware and software platforms that allow users to develop and test embedded applications and ideas. Take your pick: Arduino, Beaglebone, Raspberry Pi, Launchpads, etc… I own a few of them, plus some less general-purpose ones. One of my favorites is mbed. It is quite easy and powerful. […]

Here you can find the project files if you want to modify it with KiCAD: RFM92W If you just want to replicate it as is, here are the Gerbers I will have the PCB made soon […]
I bought recently this bike from Praktiker and I am really pleased with it! The only thing I regret is that it is not greek-made. This was the best offer at the time I wanted to buy one, at 210 euro. It comes from Bulgaria, it is branded ‘Interbike’ model ‘Sintero’ Aluminum alloy 7001 frame. It looks and feels more […]
Well, I started working on the new LoRa modules I got from HopeRF, today. I decided I would make a small pcb to accommodate a module, a microcontroller and some LEDs and buttons. My EDA suite of choice is kicad once more. I made a footprint and schematic symbol for the modules. I’ll post here any progress…
OK, it is made with the “WordPress” android app! Seems great. I’ll be using it from time to time.
