    Probably they are having a hard time because of all the great entries. It must be hard to choose.

    one more was added as far as I could tell called "Adapt a clock today! Cheap trackers boost solar panel and solar cooker performance", by gaiatechnician. I don't remember ever seeing this entered in the contest before June 16th (after the closing date - go figure)

    That was the only one added after the rest. The list was narrowed down to finalists based on votes. After looking at the entry we decided that it deserved to be considered as well. After that, it's up to the judges to decide.

    UPDATE: The announcement will have to be tomorrow. It appears that someone who I won't name by name forgot to vote and really wants to. Sorry for the delay.

    hmm... 2 are missing from the list of finalists, one of which is mine... were they decided to not be up to snuff or something?


    Reply 11 years ago on Introduction

    It's down to 49 finalist this morning, two are no longer with us! One was about making bio diesel and the other about making bowls out of waste paper. However the instructablers of these both had other entries in the finals. So ..... I guess we are all biting our nails!


    Reply 11 years ago on Introduction

    I get it, so out of the original finalists we're at the knock-out stage, hmm how long does that take do you know?


    Reply 11 years ago on Introduction

    My loons need changing lol. I don't do this waiting for results thing very well. Good luck Stinkymum

    So it's about 4:30am Instructables Time, they must be about finishing their second gallon of coffee by now, 'phoning the people over at Discover. Why have we heard nothing yet?!!

    I thought mine was original enough to be a finalist. guess not. (And I though a 20% improvement in output from solar panels might make people look twice) Anyways, please note that the clock based solar tracker is now a collaboration. If you have any old clocks at home, please take one apart, add a "gearwheel" instead of an hour hand and as long as it can handle 100 g (4 oz) of weight attached to a string and still keep time, it is viable. brian
