A 555 LED chaser shaped like a cat.
Blinkycat gerber is an open-source printed circuit board by hariskadayan, from the hariskadayan/blinkycat repository on GitHub. It is a 2-layer board of 78 × 71.7 mm with 18 parts on 18 nets, routed with 224 tracks and 11 vias.
It is built around the NE555P. Its parts include 10 diodes, 2 capacitors, 2 resistors, 2 ICs and 1 connector.
I created a 555 LED chaser shaped like a cat. It has 10 LEDs and was designed in KiCad. This was designed for Hack Club's Stasis program. The schematic and PCB is below:
| Qty | Value | Footprint | References |
|---|---|---|---|
| 10 | LED | LED_THT:LED_D3.0mm | D1, D2, D3, D4, D5, D6, D7, D8, D9, D10 |
| 1 | 0.01µF | Capacitor_THT:C_Disc_D7.5mm_W2.5mm_P5.00mm | C2 |
| 1 | 1KΩ | Resistor_THT:R_Axial_DIN0207_L6.3mm_D2.5mm_P7.62mm_Horizontal | R1 |
| 1 | 1µF | Capacitor_THT:CP_Radial_D5.0mm_P2.00mm | C1 |
| 1 | 4017 | CD4017:DIP-16_W7.62mm | U2 |
| 1 | 470Ω | Resistor_THT:R_Axial_DIN0207_L6.3mm_D2.5mm_P7.62mm_Horizontal | R2 |
| 1 | 50KΩ | Potentiometer_THT:Potentiometer_Vishay_T93YA_Vertical | RV1 |
| 1 | Conn_01x02_Socket | Connector_PinHeader_2.54mm:PinHeader_1x02_P2.54mm_Vertical | J1 |
| 1 | NE555P | Package_DIP:DIP-8_W7.62mm | U1 |
It measures 78 × 71.7 mm and has 2 copper layers, 1.6 mm thick.
18 parts, built around the NE555P. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the hariskadayan/blinkycat repository on GitHub, at the commit this page was made from: the board is pcb/blinkycat_gerber.kicad_pcb and its schematic pcb/blinkycat_gerber.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask hariskadayan before reusing the design.
