I’m pleased to announce that the SensUs 2018 Uppsala Team is off to a smooth start into the design process of our Biosensor. We have an interesting concept planned and are now trying to work out how to get all the little bits and pieces that make up our device to work optimally. Our support network is also expanding steadily and interest is slowly, but surely growing. We look forward to keep up this momentum over the coming months!
Last weekend we flew to Eindhoven to attend to SensUs contest 2017.
General atmosphere at the contest on Friday
On Friday 8th September was quite hectic: we were doing measurements for almost 3 hours, explaining the theory behind our biosensor in the “market” area and we had two pitches (technical and translational).

Saturday 9th September was also exciting and full of events. We had the opportunity to share our work with other students, researchers and participants in the contest in the “market” area and we gave a popular science pitch about our biosensor.

We had the pleasure to listen to a great talk by Dr. Khayat and finally the awards ceremony. Go to www.SensUs.org and read more about the winning teams But we have to mention it… we were super happy to WIN the CREATIVITY AWARD.
Today, we finally got the ADC running on the digital board from a SW point of view . We are using the TI … secret … until the competition. We are struggling with some address problems of the I2C, which caused some severe problems on the bus, that made the SW fail.
The housing also has been optimized for FDM manufacturing and now it worked out. We even have metal threads to be able to mount the lids tightly on the box.
The new housing is designed and is going to be sent into production. As we measure light intensity a high-sophisticated design to keep as much light from the surrounding away from the sensor is crucial for the project success.
The old housing got to small and also the plastic used was not sufficient to keep all the light out. In contrast to the old housing the new one takes advantage of screwed lids, which are sealed with o-rings from a local company (Dione in Uppsala). Moreover everything is supposed to be accessible easily since every side can be opened.
The first batch of prototype hardware is finished, tested and works except for some minor problems. Three PCBs will be sent to Germany now to our senior software architect, Elmar, who is supposed to leverage FreeRTOS to get out the maximum of the ESP8266.
