Cycle Pole: Conclusion

Bildschirmfoto 2014-06-25 um 18.07.39

Hey everyone, here is a final update on the outcome of my project. I designed the concept Cycle last summer. One year later, I now got back to the project to ‘make it work’.  My goal was to create a fully functioning prototype, to be able to do real life user testing in an exemplary […]

Final Project: 9th update


For my new prototype, I designed internals, that slide into the tube and hold the electronics in place. I made them in the workshop from MDF. Although my new prototype also serves as a visual model, these internals are not primarily designed to exactly fit the prototypes electronics and do not necessarily represent the internals […]

Final Project: 8th Update


Testing My Quik’N’Dirty prototype is finished. I boiled down the core functions to one prototype with adjustable heights and widths for testing. I applied my electronic setup. Here are some first impressions from setting it up in the workshop: This morning I took the prototype to my exemplary case scenario S Prenzlauer Allee. Here are […]

Final Project: 7th Update


As it turned out re – exchanging those buttons for PIRs was a lot more complicated then expexted. When I simply plugged in the sensors, they didn’t work properly. After a lot of testing I figured, that at least two of the eLab’s three PIRs appeared to be broken. I ordered new ones from Tinkersoup, […]

Final Project: 5th Update

Just a quick update: I managed to implement the millis() function correctly into my  code. Before the sound was only triggered, when both pedestrian and cyclist are detected simultaniously. Now it also triggers, when a bike is detected and a pedestrian has been detected recently (within the last four seconds). So I’ve got the main […]

Tutorial: Serial Communication

These are notes I took for myself, that helped me understand and remember how to implement Serial communication in my code. Serial communication can be very important for troubleshooting, to see what bits of the code are working properly and which aren’t. It can also necessary for extra functions like for example communication data to […]

Tutorial: Voltage Devider

Better late than never: These are notes I took for myself, that helped me understand how a voltage devider works. I think it’s quite an important thing to know, because components like potis are based on it and a lot of other components need to be combined with a second resistor to work as a […]

Final Project: 4th update

Just a short video on implementing a second input:I went back to using pushbuttons instead of motion sensors for easier testing for now. Now pressing the first button represents detecting a pedestrian, pressing the second detecting a cyclist. Only when both are pressed at the same time, the sounds are played. I am currently experimenting […]
