DC2N4 low-cost and Tiny C2N Monitor update

After work today I managed to program all the micro-controllers for Tiny C2N Monitor so once I get the PCBs from manufacturing, build and test one device I should be able to set the final price and ship kits out 🙂

As per DC2N4 low-cost, I managed to finish my first draft of the PCB, using the datasheet of an enclosure, the one I plan to use, as reference. I ordered a few of such enclosures in order to do the necessary validation of the design before I send it to production. Exciting times ahead!

    I requested a device a few times over the past 2 years. Still havn’t had confirmation of me being put on the list for the next batch.

      Apologies for that. However, there is no “next batch” as such.

      The hardware of the version of DC2N4 that I decided to distribute has only been recently finalized. The final cost is not yet entirely finalized as I am still trying to get components and manufacturing costs down as much as possible in order to address critics that my devices are too expensive. For these reasons I have not allowed pre-ordering of any version of DC2N4 (or DC2N5). I am not building DC2N3 at the moment as it takes too much time and I haven’t got enough of it. I am not building DC2N2 either as it takes even more time to do so and is even more expensive than DC2N3 due to the parts and features I’ve put in.

      As I commented before, when time-scales are so long and details uncertain it makes little sense for me to accept pre-orders as by the time a pre-ordered unit is available potential buyers might not be interested any longer. I also commented that there will be a web page here for ordering once things are finalized.

      It would have taken significantly less time to go to market if people hadn’t criticized my prices in the first instance: DC2N4 would have started selling years ago for 40 GBP, due to the components I use in its design and also the capability to self-update. Most people did not react positively to that so I decided to change the design 2 times.
