Here are a couple x-ray photos of the Mark’s damaged dome (upper and lower left, mine on the upper/lower right.). Note: Mine still had the ribbon cable attached. Mark’s was severely damaged and pulled all of the trace lines just below the solder mask layer of the board. Below is an x-ray of both mine and @mark.urwiller dome. Mark was gracious enough to send me his cap which didn’t have a chunk of plastic broken that mine suffered. I removed his light sensor CCA and swapped mine in its place. I reconnected the ribbon cable and it responded to a flashlight being shined on the sensor.
Mark’s CCA is salvageable (tempest sent him a new one) and I will try and repair it in the event someone else needs a spare. One of the x-ray photos show the connections that need to be made. There are 3 vias for the control lines that can be connected to the connector once I put it back down on the board. For the ground and power lines, I likely find a donor scrap CCA to rebuild the board traces. I’ll use 30 or 36 gauge wires to make the connections to the board.vias. Henkel makes a product called Hysol that is great for circuit trace repair.
Anyway, just thought I’d share some of the photos in the hope it may help people in the future. The connector is a 0.5mm pitched FFP/FPC ribbon cable connector. It can be found on the web with a little searching around. I used a hot air gun to remove it applying Kapton tape over the plastic parts to retard the heat transfer to the plastic.
This is a little off-topic, but how resilient do you think these things are to taking hits? I did basically exactly the same thing you did - but it didn’t appear that any of the sensing bits broke off. The Tempest device did break right above the mount where it revealed it was held together by 4 small screws in plastic. The female plastic bits broke. But I was able to super glue it back together and get the device mounted properly. It has some scuffs where it hit my shingle roof on the side of the haptic sensor but otherwise looks normal. It appears to be working… but hard to say if it’s working accurately! I am no worried that I have poor data!! You seem to have a good understanding of how these work - might I have done some irreparable damage?
I’ve picked up a 2nd hand one that got damage to the same part but this is a newer model design.
It was initially only pulled out of the socket but I think it sustained some damage on disconnection because the light sensor kept going bad.
Hope I can get a new cable connector or the complete sensor as I can solder the haptic one back in without replacing it.
cap and body are not from same batch and aren’t compatible. You can ask support for a recent cap, open a support ticket but before doing so check that the pins of the connector are still ok and also that lower part seems odd (might be a photo distortion).
The cap and body matched and was working briefly but either I damaged the terminal on the fcc or it was on its way out anyway.
I tried to replace the terminal by soldering a similar terminal on but couldn’t find one to match exactly.
Just photo glare from the conformative coating!!!
I’ve put in a request for a replacement component of at least a cap🤞
Is the ribbon cable connector still intact on the light sensor? if so you can get the ribbon cables of places like ebay or amazon, I had to replace some of mine when i repaired the pressure and temp sensors.
Negative the ribbon cable tore and doesn’t appear to be replaceable. Any idea of where to start to look for replacements as I’ve not seen a part that will fit?
you can replace them they are a socket on each end on my version… your version is slightly different but could still be socket i think i can see the socket tab on your sensor top, what you need to do is check both the main unit and the top if they are sockets then just count the pins mine is a 5 pin at 0.5mm pitch ribbon cable and then just do a google search.
