#1-#2 OK running along paths
#3 should have used the top of the hill to find the flag, not searched for a long time on the hillside
#4-#5-#6 mostly OK
#7 The southern route (blue line) would have been faster
#8-#9-#10-#11-#12-#13-F mostly OK
TEC-Drive heat sinks
I made four heat sinks from aluminium L-profile for the linear TEC drive. Two 30 mm long for each side of the H-bridge (middle), and two 50 mm long for the voltage regulators(top right).
The regulators take 5 V input and produce 2 V, so they each dissipate 3V *ITEC Watts. The H-bridge dissipation is load-dependent, but for a low resistance load the dissipation is almost 2V*ITEC Watts. Here I am using a resistor (lower left) as a dummy load.
I tested the drive at 1 A for a few minutes, and the heat sinks do get quite warm. For continuous use at 2 A I think a fan will be required.
Iltarastit, Velskola
#3-#4 OK
#12 got a bit wet at the swamp which would have been better to go around, + 1 min.
#6 OK
#11 difficult hilly area where I headed for the wrong cliff at first, +3 min.
#14-#15-#16 OK
#17 was unsure on how high up the hill the control should be. +30s.
Itärastit, Käringmossen
Orienteering close to the Ämmässuo/Käringmossen trash dump.
#1 a bit tentative, maybe should have used the path SW of the control
#2 OK
#3 good orienteering into the control-circle, but then failed to find the flag for about 3 minutes...
#4 the plan was to use the cliff (blue line on the map) to find the control, but I failed to execute and circled around the hill on the wrong side. Another +3 min mistake.
#5 no mistakes but slow
#6-#7-#8 OK
#9 initially I had the right direction out from #8, but then somehow deviated down the wrong side of the hill (looking at the compass might have helped). Maybe 2-3 min lost here.
#10-#11-#12-F mostly OK
I didn't make it into the official results but my placing is roughly 20./62.
Firmaliiga 2013/6, Luk
The last firmaliiga event for this season was held yesterday at Luukki.
#1-#4 mostly OK
#5 very slow route choice through bad terrain with fallen and cut-down trees
#6 a small 1min loop to find the control
#7-#8 OK (a small loop on #7 close to the control)
#9 maybe +1min here again as I followed others to the left when the control was right.
#10 again followed others to the wrong control before finding my own, +2min maybe
#11-F slowest ever finish as I tried to figure out where it was...
Firmaliiga result 49./61
Itärastit, Svedängen
Fast running on most legs, but I made a complete mess out of two controls!
Itärastit, Salmenkallio
- #2 could have taken a more direct route close to the control
- #6 ran very very close to the control - then decided to search right for 200m when the control would have been to the left about 5m.
- #7 should have clearly chosen either the path or the road - now an in-between choice that wasn't so great.
Firmaliiga 2013/5, Solvalla
Flatter terrain compared to last week - easier to keep up the pace on the whole course.
A stupid mistake that cost maybe 2 minutes on #1 - otherwise mostly OK orienteering.
Firmaliiga result 24./58
Firmaliiga 2013/4, Kattilajärvi
First firmaliiga event this fall. Overall very physically demanding with most controls placed high up on hills/cliffs.
#1 a bit of circling before finding the right control
#2 ok and safe route, but slow
#3-#4-#5 OK
#6 very long leg with one or two big hills in the way. A route-choice with more running along the road might have been better.
#8 I tried to plan a good route to this control on the way to #6, but other runners and poor judgement caused extra minutes wasted here also.
Firmaliiga result 45./59
Iltarastit, Kattilajärvi
OK orienteering but not that fast running. Warm weather and hilly terrain. Maybe a bit surprisingly the big detour from 4->16 using roads and paths worked out OK since it was my second best split-time in terms of placing.
