Laser rifle: common questions
What microcontroller does the Laser rifle use?
The Laser rifle is built around the ATtiny85V-10P, from the AVR/Arduino family.
How big is the Laser rifle PCB?
The Laser rifle measures 56 × 15.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Laser rifle?
27 components, from 21 distinct parts. The full bill of materials is listed on this page.
Where can I download the Laser rifle design files?
From the Dade3e/laser_rifle repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Laser rifle design in my own project?
The repository has no license, so all rights stay with Dade3e. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Laser rifle 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.
