BNE14T30 converts a B-heptomino into a glider. Tanner Jacobi found the converter on May 26, 2015, building on a Bellman search result I found on January 9 that year.

Both contributions belong in its story. LifeWiki credits Jacobi’s converter and identifies the earlier result it uses.

An edge shooter

The catalysts include a transparent block and a 23-cell still life. The unusual feature is geometric: the reaction never extends beyond the outgoing glider’s lane.

That makes it an edge shooter. Its output can run along the edge of other circuitry without the generating reaction intruding into the space on the far side of the lane.

Connecting circuitry

It accepts a B-heptomino input and can connect to Herschel circuitry through converters such as HFx58B. Recovery timing limits how often it can accept another signal; LifeWiki records a 120-generation repeat time, or 126 with an HFx58B input.

The source article supplies the pattern and links both discovery reports.
