Flat RotorHazard / Delta5 Laptimer Enclosure

thingiverse

<h1>Lap Timer, Enclosure. FlatCase Version / Delta5 RotorHazard</h1> **EDIT**: - Added Pi4 version 20/11/19. I have not printed this and tested it. Dimensions taken from the PI foundation specs. Print at your own risk and please let us know if it needs alteration! A new 'flatcase' design intended to prevent stacked PCB's used in previous designs from obscuring each other. Centralizing the RX5808 modules in the case for ease of foil lining the enclosure with a single letterbox in the RF shield. Available in a 4 node and 8 node variant. The 8 node variant has enough space in it to support a suitable lipo pack or six 18650 cells. An internal power supply is 'under development' and currently unsupported. I am designing required charge circuit, wiring, 18605 pack, etc. But for now... the space is there if you would like to experiment! The Delta5 V2.0 PCB is secured into place by hold down tabs at one end and a PCB clip at the other. Clip secured by one M3 cap head fastener. The traditional XT60 power socket has been deleted in favor of a DC jack that is compatible with common POE injectors. An XT60 to DC jack adapter can still be used to power the timer. Mounts for an INA219 High Side DC Current Sensor are included in both 4 node and 8 node version. 4 node version mounts the INA219 to the lid due to space constraints. In addition, the HDMI, Audio, USB sockets of the Pi are no accessible behind a pop out/in cover. Print this in a flexible filament E.G.
