Final Preparations Are Taking Place
Hi all, I am currently working through the last steps before the production run. Let me get you up to date on the current developments. Read the full update.
Battery Charger Components and Current Production Timeline
I want to give you an update on the current production timeline. After all, the campaign conclusion was at the start of 2022. So let me try to explain why there is still no parcel at your door with a tiny NFC capable GNSS receiver. Read the full update.
Adding New Documentation
Hi all, I have setup a readthedocs for the unsurv project and more specifically unsurv-offline. Over the coming weeks you can expect multiple campaign updates, each adding to the permanent documentation available at readthedocs. Read the full update.
New Design and Delivery Schedule
I come with good news and, as always in these times, some mixed news. The good news: I have completed the PCB review, changed the PCB stackup and rerouted all components. Bad news: I received additional info from Mouser that two more parts of the device are being delayed. Both of them are in the circuit responsible for power switching between 5 V USB and the battery. The upside here is, that it's better to replace them with a single IC anyway. Read the full update.
Component Lead Times and Next Steps
This time I bring mixed news. Although I planned ahead and ordered parts as soon as I could reasonably expect the campaign to end successfully, the chip shortage curse has struck this project. The good news is: it only concerns the dipswitch for the USB to UART IC and a diode controlling power when switching between USB and battery as a source. Read the full update.
Sourcing Components, Updated PCB Design
Although sourcing components is still difficult in 2022, just as it was last year, I have good news to start the year. Read the full update.

The update this week is about new features of the companion Android app which lets you interface with your unsurv offline. Read the full update.
Offline Syncing with Unsurv
This update re-focuses on how to use unsurv offline. You'll learn how to automatically synchronize offline any kind of data on your unsurv using a small home-grown server running on a Raspberry Pi. Read the full update.
The How, What, and Why of Unsurv
This update is about the general goals of the unsurv framework and what kinds of technologies it uses to better understand offline surveillance. Read the full update.
Making a fitness tracker with unsurv
Welcome to the first weekly update about unsurv offline. Over the coming weeks you will learn what inspired this project, how to improve data on OpenStreetMap, and how to automatically synchronize data from unsurv offline to a small, homemade server. First up though: a custom fitness tracker. Read the full update.
