#1 conservative route along road/path, too long.
Perhaps #4 is also too safe?
#6 should have cut in from the road towards the control circle sooner.
#9 has a strange and unnecessary U-bend (to avoid the slow green stripes?)

A good run on Tuesday at Firmaliiga resulted in much tiredness both in the legs and in the mind on Thursday. I search for #1 too soon and to the right, try to find #2 too late and on the wrong hill, make a mess out of what looks like an easy #5-#6 leg, take a bad direction out of #8 to round the lake to the north, and finish off on #10 by running just past the control inside the circle.
Anyway they all count as experience I guess... 🙂
Firmaliiga 5/2014, Solvalla
The second firmaliiga event this fall, at Solvalla quite close to the first one.
Close to #1 I should have had a better plan - I've just graced the control-circle and then looked in the wrong direction for some random big stone. Around 90 s lost.
#2-#3 quite OK. To #4 my route is probably too zigzaggy - less turns and leaving all the green areas to the left(north) is probably better. To #5 the paths on the left were apparently a bit clearer and faster? To #6 I was too high up the hill and didn't find the path.
#7-F is quite OK again.

S-#1-#2 OK, then towards #3 should have rounded the steep cliff altogether and avoided the ascent/descent after #2 - still #3 and #4 are among the best splits.
A complete blackout after #4 when I ran 180-degrees in the wrong direction for a while 🙁
#6 OK but then very close to the correct stone at #7 a loop to the right instead. #8 is again a good split - mostly running along paths and roads.
Then again completely the wrong direction out of #8 🙁 #10 and #11 look like good splits but didn't feel that great as the vegetation was thick and thorny.

An easy course where the challenge was keeping up speed and planning well ahead so that there were no walking breaks or stops. 4th out of 40 runners is pretty good although the level isn't that high on these Saturday events 🙂
- #3 somehow ran past the control and up the wrong hill. over 2 minutes lost 🙁
- My zigzag route to #5 isn't good. Straighter or staying on one side of the control-line would be better.
- To #7 along paths - safe but maybe too slow. Perhaps straighter down the hill out of #6 would have been faster.
Firmaliiga 4/2014, Nuuksionpää
Fourth firmaliiga event of the year yesterday at nuuksionpää in the Noux national park.
- #1-#4 mostly OK, perhaps a bit slow/unsure running to #1.
- #5 a lot of time lost here for some reason - maybe straighter along the #4-#5 line has less ascent/descent?
- #6-#9 again mostly OK
- #10 only major mistake - quite thick forest with low visibility, I wasn't high enough up on the hill, and ran through to the road behind the control before turning back and finding it.
- #11-F OK.

After a summer break it's time to start orienteering again.
Stable, controlled, and positive run today! Perhaps because rain and thunder had lowered the temperature by five degrees to around +22C so it wasn't as hot as otherwise lately.
- at #1 should have followed the path for a bit longer, and read the map more carefully to check that the control is actually quite high up on the hill.
- #3 perhaps a straighter route in the beginning - and then "punching through" to the big path with speed instead of a tentative J-bend close to the control circle.
- Found #7 before #6 - should have used better intermediate checkpoints when stepping off the path close to #6
- To #11 I actually planned to take the norther road but then aimlessly ran down the hill out of #10 and found myself on the straight road south of #10.
Pulse Stretcher - V2
Update: kicad files: 2014-07-23-pulse_stretcher_kicad
A development on pulse stretcher V1.
This circuit is used to stretch a short 10 ns pulse from a photon-counting module to a 100ns long pulse that can be more easily recorded or time-stamped e.g. with the white rabbit fine-delay FMC.
The new circuit is the same LT1711-based design as the old one, with an added buffer (BUF602) on the output. This improves output-load handling because the BUF602 can drive both 50 Ohm and 1 MOhm loads.
The PCB is made to fit a BNC-BNC enclosure by Pomona.
Some testing with an artificial input-pulse from a Keithley 3390 signal-generator..
.. and with the actual PMT-pulse. Note how the 100MHz scope produces nice round smooth signals while the 500 MHz Tektronix reveals more of the ugly truth.
Furka Pass and the Rhone Glacier
On the way back from EFTF2014 in Neuchatel to Zurich airport we took the scenic route via Grimsel Pass (2165 m) and Furka Pass (2429 m), stopping to look at the ever shrinking Rhone Glacier on the way.

Kuopio Jukola
2nd leg of Kuopio-Jukola. Quite hilly terrain with soft&stony ground which was difficult to run on.
#4 drifted down the hill to the wrong control, then ran past my own control and backtracked to find it.
#5 past the control down the hill to the swamp, then back up the hill again.
#8 again found the wrong control before my own.
