p21 honey farm hassler is a period-21oscillator found by Dongook Lee on January 3, 2016.[1] It is a pipsquirter, which makes it useful as a sparker; it also produces V sparks that can be used. As shown in the gallery below, oscillators of periods 42, 63, and 126 (21 times 2, 3, and 6 respectively) have been created using the honey farm hassler.
Period-42 pulsar hassler. The spark used is the V-spark, but it interacts a few generations earlier.[2] (click above to open LifeViewer) RLE:herePlaintext:here
Period-42 R-pentomino hassler, found by EvinZL on 8/5/21[3] based on a partial by David Raucci the same day.[4] The spark used is the V-spark; the pipsquirter spark would work except that the p21 honey farm hassler would get destroyed later. (click above to open LifeViewer) RLE:herePlaintext:here
Period-63 skewed pulsar hassler, found by David Raucci on 7/20/21.[5] The spark used is the pipsquirter spark. (click above to open LifeViewer) RLE:herePlaintext:here
Period-126 pi-heptomino hassler. The partial was found by David Raucci, and the extraneous beehives were cleaned up by praosylen and Matthias Merzenich.[6][7] The spark used is the pipsquirter spark. Note how one of the catalysts in the p21 honey farm hassler is also used as stabilization for the p7 double thumb. (click above to open LifeViewer) RLE:herePlaintext:here
