+Hi.
+This is my main page. It will do until I build a better one.
+I'm busy on a number of things.
+The [[boards:sbc:yaz180|YAZ180]] was my hardware build through 2017 and 2018. It is now pretty much finished on PCB version 2.4 and is in daily use.
+I'm fairly active on the [[https://github.com/z88dk/z88dk/graphs/contributors|z88dk]] development platform and am (sort of) responsible for ROMWBW [[https://github.com/z88dk/z88dk/tree/master/libsrc/_DEVELOPMENT/target/hbios|HBIOS]], [[https://github.com/z88dk/z88dk/tree/master/libsrc/_DEVELOPMENT/target/rc2014|RC2014]], [[http://github.com/z88dk/z88dk/tree/master/libsrc/_DEVELOPMENT/target/scz180|SCZ180]] and [[https://github.com/z88dk/z88dk/tree/master/libsrc/_DEVELOPMENT/target/yaz180|YAZ180]] targets there.
+I'm often talking about [[https://groups.google.com/forum/?forum/rc2014-z80#!forum/rc2014-z80|RC2014]], and have built a standard (no added features) [[https://github.com/RC2014Z80/RC2014/tree/master/ROMs/CPM-IDE|CP/M supporting FATFS]] IDE drives (CF and PATA) for the RC2014, and have written some entries on [[https://github.com/RC2014Z80/RC2014/wiki/Using-Z88DK|using z88dk]].
+I've recently built a IEEE-754 compliant 32-bit floating point library //[[https://github.com/z88dk/z88dk/tree/master/libsrc/_DEVELOPMENT/math/float/math32|math32]]// for z88dk, which can be used with both sdcc and sccz80. It is the only (to my knowledge) floating point library which supports both the z180 **//mlt nn//** , and the ZX Spectrum Next **//mul de//** instructions, which are used to deliver a substantial performance improvement over “soft float” libraries. The z80 version of the //math32// [[https://github.com/z88dk/z88dk/wiki/Classic--Maths-Libraries#benchmarks|library benchmarks]] pretty well too.
+Unrelated to retrobrew, the things I'm known for (measured in internet hits) are throwing a freeRTOS version for Arduino into a library called unimaginatively, [[https://github.com/feilipu/Arduino_FreeRTOS_Library|Arduino_FreeRTOS_Library]], and for [[https://feilipu.me/2013/07/16/paywave-paypass-deletion-via-rfid-antenna-kill/|punching holes in my credit cards]].
