Version 3 of the birdhouse is almost finished. I will do some software testing over the next few weeks until I will replace the current birdhouse in September. There are some nice features in v3 like a scale with the NAU7802 ADC and two load cells (better mechanical stability). The sides, back and top panel are now glued together to provide better moisture protection. And I have replaced the veneer on top of the scale with cork. Cork is very flexible, naturally water proof and provides good temperature insulation for the birds sitting on top of the scale in winter. The only drawback is it smells a little bit of old wine cellar (I hope the birds will not mind ;-) ). I would also like to keep this birdhouse running for more than a year (the previous versions where only out there for about a year each). I will still clean out the birdhouse/do maintenance whenever needed but I'm curious to see how the birdhouse will hold up over a longer period of time. If you are interested in any further details then please check out the Version3 zip file.
