The nature of the project makes several controlling choices ‘the obvious choice’. The clock only needs 28 outputs for segments and 1 for the ‘dots’ in the middle of the clock (the option to turn them on and off is nice to have). finding a microcontroller with 29 outputs is …
A quick idea based on other peoples thoughts: A lamp that is motion triggered but the light output is based on the ambient light in the room. For instance take, a dark room. When a person enters the room, a bright light is not comfortable. A red light slowly dimming …
This post will deal with the construction of the display segments. Not the individual strands of LEDs – they are done already. Instead the post will be about the casing that the segments will have. I started out by testing the Ledberg lamps (see previous post). Since it worked so …
Now for some practical stuff. I have created a simple breadboard solution for the driver circuit and hooked 7 Ledberg lamps up to NMOS transistors. The breadboard is quite a mess! whats in there is: on top a PIC16F688 MCU. below that is a 7805 linear regulator for supply. The …
The project description of this clock is a little bit backwards. The project has been active for some time but I haven’t come around to write about it yet. The clock has its intended use outside at a wakeboard park, where it would be very nice to know the clock …
