ESP_NOW Remote Controller

At a DIY shop, I found a rubber bushing of just the right size for making a remote control unit.

Considering the storage of a battery unit, I tried to introduce a “chocolate caviar tin,” but was unsuccessful due to opposition from the owner of the tin.

Deciding that an open structure would be best for accurate access to the tact switch, I began arranging the parts.

The rubber bushing is sandwiched between the circular parts placed on the back side, and the rubber band that attaches the board and remote control to the palm is fixed in place.　The battery will be stored in the concave side of the rubber bushing.　

The location of the switches, while the spacing feels a bit narrow,

Located at the point where the fingers are naturally bent.

It would be perfect if a circular PCB with an enlarged diameter of 5 to 10 mm could be fabricated to allow more room for the placement of the switches.

After attaching a rubber band to the base and drilling holes for wiring, the device was temporarily mounted.

Finger and palm size is probably difficult to standardize as there are too many differences between individuals.

In my case, my palm is larger than average, but my finger length is average.

The index finger handles the 5th/6th switches assigned to functions other than pitch operation. These two switches are also used to change modes.

Adjust the position of the band over the palm for easier access.

The 5th/6th switches are graded in button height.

This is the finished product.

The pitch should be re-mapped.

Mapping of pitch change values to Hammering On / Pulling Off.

The movement of the spring off side needs to be refined, but if there is no problem in use, it may be OK as it is.

I have not found a solution to the problem that the i2c driven by the switch sends only one item of data and ignores all data attempted to be sent in succession.

I have added a Global Controller to the instrument to deal with this problem,
