Good news, seems like finally we got the clicks right and the new batch of VI's are ready as well. Hopefully these will work perfectly.
The remaining orders will be sent out in about 2 weeks with the new VI and there will be a few more kits available before the release.
The click disc production won't be ready until the end of February, after the Chinese holiday. Currently end of March looks likely for the release.
This is how the final indicators will work.
First it's heated until time out at 280C,
then on the 2nd part of the video it's heated until the led stops blinking at 400C which is about the same temp as the previous heating method. Then we overheat with the IH where the indicator reaches the end and a little more with a torch to test if the spring can get stuck or the leg get out of it's hole on the side.
