SFP connector footprint

Single SFP/SFP+ SMD-connector and cage footprint.

FreeCAD V-carving with OpenVoronoi

Sliptonic has worked on connecting FreeCAD with OpenVoronoi to produce V-carving (aka medial-axis) toolpaths.

I worked on the OpenVoronoi stuff 7 years ago and we made this video back then:

Itärastit Latokartano

2019 orienteering season opened.

Not too warm around +5-6 C - with a bit of snow/sleet in the afternoon - welcome to Finland in May 😉

#3-#4 leg looks like a big detour - otherwise mostly no big problems - but a fairly easy pace today...

Mowers gonna mow

The Automower logged 516 hours last season. Now in action again with new sharp blades.

AD8015 transimpedance amplifier

AD8015, 10 kOhm transimpedance 240 MHz bandwidth photodiode amplifier.

This is not Stable32

Recently merged plotting-functions for allantools with a look and feel of Stable32 - thanks to yxie.

I should probably run python3 to get special characters like tau and sigma to work..

SFP Connector

20pin SMD connector + cage for SFP transceiver.


Some views of 1 Gbit/s (that's 1.25 GHz, or 800 ps per bit) synchronous ethernet bit-patterns.

4 GHz 'scope

We got this 4 GHz 'scope at work. 111 ps is roughly as expected for the rise-time of a fast edge. Signal from a leo bodnar pulse generator.

RA0SMS mini-whip

New RA0SMS mini-whip antenna on the roof. The old one lasted from 2017/02 to 2018/10.
