Thursday I did it test with all my sensors for 24 hours. It went rather well but there art two main points of attention.
Mathe, Richard an me working (no we're not terrorists)
1. The stealth cam. It has limited capabilities in storage capacity and battery capacity. When I set the resolution to low it should be able to hold 350 pictures. This is not the case, it holds 300 max. Another drawback is that it’s very hard to make out to which resolution the cam is set. So I accidentally set it to high. As a result I couldn’t complete the whole day because I was with friends and I forgot my cable so I was stuck for the evening with a full camera. But I did get some nice shots (view right.)
It takes just one AAA size battery. I used up only 2.5 in 13.5 hours so that was fine. I do have to carry a spare one with me where ever I go. I bought a quick, one hour charger for four AAA batteries so I will never go without.
Tiny cam can be attached with Velcro to a card
I’ve found a very nifty solution for wearing the camera. I can pin or clip it to every sort of clothing. The images are still shaky but he, life is bumpy ;) To my relieve people didn’t look too suspicious when I passed them, I’m still a bit embarrassed though.
It was quite a puzzle to see where I missed pictures. (In the future I will note exactly when the camera stopped and restarted.) When I empty the storage it takes at least a couple of minutes to store them on hard disk. So there are gaps. I filled the gaps with duplicate pictures but I’m still files short…? I think the 60 second laps probably isn’t exactly 60 seconds so after a couple of hundred pictures you start noticing that. I’ll have to wait and see how that works out in the app.
The main challenge is dealing with the gaps in the data from all the devices.
2. My Suunto watch does a great job during the day but when I sleep it loses connection with the skin and it stopped at 4 a.m. Which was still almost all night. But it will have to do better when the project actually runs. I think I’ll buy some medical tape to fasten it for the night.
I don’t think it can log 24 hours of data, but it’s close. To be on the safe side I’ll store the data somewhere in the middle of the day.
Logging my activities was a very mindful thing to do. I thought it would irritate me but it made me quiet and alert at the same time. May be using pencil and paper helped there too.
