My nephew asked me if I could help him design a school project, a bicycle back light that could be remotely controlled to blink and emit sound.
I engineered a solution around a 315MHz receiver.
This is the (updated to rev 2.1) schematic.
File:RF Achterlicht rev2.1.pdf
31 January, 2018, made component placement
Also updated the schematic: File:Rf achterlicht rev 2,2.pdf this is the component placement drawing as a .PDF : File:Componenten opstelling rf backlight rev 2,2.pdf
this is a 3D rendering of the PCB with this component placement, it has not been layed out yet, (no copper traces routed yet).
J1 connects to the manual on switch J2 connects to the piezo buzzer J3 connects to the 3V battery J4 is an optional connection to a commercial 315MHz receiver (for testing).
