E-Bike Battery Surgery

battery deadOne of our long term visitors is an e-biker. One of his batteries was on the blink. There was no output on the normal output connectors, but there appeared to be an output via the charge port. We suspected that the balance circuit was shot, but when we opened the battery case, it looked like one of the cells was physically damaged. Lots of pics here.

We ordered a replacement cell. When we removed the bad cell, we noticed some others damaged. It looks like we need 4 replacement cells in all. We plan to cannibalise these from an old spare battery. We tested the remaining cells and they seem able to take a charge and deliver reasonable current. A 2 Ohm power resistor came in handy. Check back with us to see how the rest of the repair went.

OSM MapJam Saturday 23rd of April

OpenStreetMap (OSM) Ireland members will meet Saturday 23rd of April in Dublin and do OSM mappy stuff on laptops in TOG. Like an indoor mapping party / hack day / social meet up / barcamp.

What is OpenStreetMap?
OpenStreetMap is a world wide, open content map. It’s often referred to as the Wikipedia of maps in reference to the fact that it is open to be edited by anyone.

If you’d like to learn more about OpenStreetMap, come along! Want to start mapping your local area, and want help? Come along! Want to find out how to use the low level OpenStreetMap data? Come along! This event is open to all.
If you’re already an OSM mapper and would like come, but not sure what to do, don’t worry we have loads of townlands to map and plenty of people who will give you a hand learning the details.

In addition there will also be a meeting of the Irish Open Source Geospatial Foundation, their first in person meeting. OSGeo was created to support the collaborative development of open source geospatial software, and promote its widespread use.
Where and When?
