Hack Linnar Viik's lawnmower

Lawnmower's immobilizer prevents using the lawmower. Disable the PIN code and claim the device. This job requires some specific skills - use Bus Pirate as SPI bus master to access the Flash chip on the device. First dump the existing firmware as-is. Enter the PIN incorrectly again and attempt to identify which part of the Flash counts the invaid PIN code attempts. Try to reset the counter first.


Fix Samsung digital signage box

The MOSFET-s in power supply chain are fried. Attempt to figure out what went wrong and fix it.

The Smartboard pen picker was lost, there's connector for that. Find a replacement pen picker or 3D print one.


We have our roots in the Robotics Club of Estonian IT College as several key memebers are graduates of the College and were active Robotics Club members in the past. Most of us have numerous years of work experience in ICT sector and we've travelled the world to see how hackerspaces and makerspaces operate. We know that we've got what it takes to operate k-space.
