Rosco grey under acrylic

On Monday we had blobs but no projection on the acrylic, so we had the idea to put rosco grey underneath the acrylic, and the result was not what we expected, in a positive way.
As you can see the projection is good and it does not interfere with the quality of the blobs.








After some more testing the configuration of Tbeta and touchlib was all set and done.

Some exta tests

After some small tests we came to the conclusion the harder we stretched sulky solvy over the acrylic the better blobs we got.



After stretching Sulky Solvy we didn't need to press as hard as before.
You still have to use a bit of force.

Testing with Sulky and Rosco

The next test we did was with a pirce of rosco grey on top of the Sulky Solvy



As you can see with rosco on top of Sulky Solvy the result is even worse then before.
We'll still experiment with this in Tbeta to see if we can get any usefull blobs.

Testing with Sulky Solvy

Today we wanted to test with Sulky Solvy applied on top of the acrylic.

We had many expectations, afther reading allot of it on Nuigroup.



So as you can see in the video we recorded, the results were very disappointing but it's possible we might did something wrong, forgot somthing, or just need to test some more.

In the second video we removed the IR bandpass filter to see if it would make any difference.



So as you can see in this video even without the bandpass filter there is not much difference.

Blob's!

We still need to make some configuration adjustment (fine-tuning) but the result we get now is very promising.

note: this is on bare acrylic!
