About the HSOD-Home-Security-Of-DOOM PCB

HSOD-Home-Security-Of-DOOM is an open source AVR/Arduino PCB design by NattDocumented, published on GitHub. It is a 2-layer board measuring 94.6 × 120.6 mm, with 35 components from 12 distinct parts.

Its main chip is the Arduino_Nano_ESP32, from the AVR/Arduino family. Other key parts include the DM-OLED096-636, HLK-LD2410C and DFR0299. By type, the board carries 14 diodes, 12 switches, 3 ICs, 3 resistors, 1 module and 1 speaker.

It belongs with the audio and displays & leds designs in this gallery.

From the project

----------

A simple home security alarm with personality and a little twist wink wink.

It is just like your simple, ordinary home security/alarm system. If you input your PIN to arm or disarm the alarm, and if you proceed to enter your PIN just in time, the alarm won't go off. However, when H.S.O.D went off... It doesn't just play a normal alarm... I will scare the burglar away (hopefully)... it plays a pre-recorded audio which you can customize/add custom audio to your liking, of how you would like to torment your burglar.

What microcontroller does the HSOD-Home-Security-Of-DOOM use?

The HSOD-Home-Security-Of-DOOM is built around the Arduino_Nano_ESP32, from the AVR/Arduino family.

How big is the HSOD-Home-Security-Of-DOOM PCB?

The HSOD-Home-Security-Of-DOOM measures 94.6 × 120.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the HSOD-Home-Security-Of-DOOM?

35 components, from 12 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the HSOD-Home-Security-Of-DOOM design files?

From the NattDocumented/HSOD-Home-Security-Of-DOOM repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the HSOD-Home-Security-Of-DOOM design in my own project?

The repository has no license, so all rights stay with NattDocumented. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the HSOD-Home-Security-Of-DOOM without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
