write guide for people using the OMB from Labmaker

[jerabaul29]

• prepare Rock7
• prepare decoder script
• update the firmware if you want (note: on ubuntu 20.04, need older uploader version)
• put batteries in
• seal "real good"
• wait for a few messages, and run the parsing scripts
• if you want, ask us to host your data on our server

@AndreaGierisch let us list points I should have in a "Labmaker buoy user helpguide" :)

• current from only 1 source
• static electricity protection
• what firmware to use
• logging debug info over USB

@AndreaGierisch let us list points I should have in a "Labmaker buoy user helpguide" :)

Sure :-) Here is a short brainstorming of points which I think could be nice to have in a Quick Start Guide or so:

• What is what when I look at the electronics?
• Create an account at Rock7 to a) buy subscription/credits and b) see the received data
• How to download and start Artemis-Uploader
• How to check whether there is (the correct) firmware installed?
• What the firmware can do, and in which cases I need to write my own firmware
• What batteries to buy?
• What magnet to buy - And can I use the OMB also without magnet (I guess so.)
• Do I have the 6-dof or 9-dof sensor (relevant for firmware, I think?)
• How to change frequency of GPS recordings / message transmission?
• Table with expected battery lifetime
• Table with credits per message (and recordings per message) and price of credits
• Dos and Don'ts like:
• • never two power sources at the same time
• • slow cool-down from room temperature to outside
• • use desiccant bags (and recommendations which/how many?)
• • seal the box with silicon?
• • How to best hold the electronics plate when taking it out from the box to reach the batteries

I think I found answers to many of these items already, but it would have been easier of course if all was collected in one place ;-)

• need to be in the dialout group to access usb port

[akorosov]

Regarding the batteries: Does the the LabMaker version have parallel or serial connection in the baterry holder? We bough OMB from LabMaker and Lithium LH20 baterries with 3.6V. Can we safely insert them?

[jerabaul29]

@akorosov the LabMaker version have parallel connected battery holders and expects 2 LSH20 in parallel yes :) . You can safely insert them, just be sure to respect polarity of course (should match the markings on both the PCB and the battery holders).

• always antenna on when RF modules in use

[jerabaul29]

Let me know how the tests go / if there is anything I can do to help @akorosov :) . Will be happy to have a chat with you and / or some of your colleagues if I can help :) .

I tried to summarize at https://github.com/jerabaul29/OpenMetBuoy-v2021a/blob/main/end_user_manual/LabMaker_OMB_instructions.md ; if you want more information, either ask for specific additions here, or open pull requests :) .
