    I'm starting a new website. Getting tired of my php site.

    I noticed my school is behind compared to other schools. I plan on getting us up to speed, while at the same time learning as much as possible. The end goal is making a rocket that can compete with waterloo's borealis. If all goes right, we'd launch it at LC 2026. This year (LC 2025), the goal is to make a mojave spinx esque rocket. I'm going to start off with recovery, and avionics. The reason being, is that it is possible to launch the same avionics in a 4 inch diameter kit rocket, that we could use in a mojave sphinx. The recovery system will be almost the exact same.

    The first thing I'm gonna do is make a very simple board in Altium. It will have the rp 2040, a usbc port, flash, a LED, reset button, pin out, USB over current protection, a barometer and an accelerometer. It'll be a bit better than a pico.

    JLCPCB \"PCB Manufacturing & Assembly Capabilities\" is kinda confusing.

    So for a two layer PCB,

    it says \"2-layer: 0.15mm hole size / 0.25mm via diameter.\" That would mean the pad width or \"annular ring\" can be 0.05mm right?

    \\[ \\frac{0.25}{2} - \\frac{0.15}{2} = 0.05 \\]

    but wait:

    Now it says: \"2-layer: 1 oz: Recommended 0.25 mm or above; absolute minimum 0.18 mm.\"

    I guess a via doesn't count as a PTH (Plated Through Hole)?

    By default in Altium you set your minimum annular ring: and this applies to vias and PTH. So... I guess Altium probably should't do this by default?

    Simple flight computer that uses all the best practices. A good place to start.

    The primary goal of dingboard is to enable my personal learning. This will be the first board of many. The successor to dingboard will be a CAN enabled system in a 4-inch diameter form factor which will hopefully be launched this summer.

    Primary Functional Requirements for dingboard:

    • Easy to operate and understand
    • Fully open source
    • Assemblable by JLCPCB PCBA
    • On board charging and automatic power switching using simple chip
    • Charging status indicators
    • MCU status indicator, sleep, data collection etc.
    • Altium and solidworks integration
    • Utilize all known best practices to enable scalability
    • Components:
      • Barometer
      • Accelerometer
      • Thermistor for battery protection
    • Use entire safe range of battery (use a buck boost)

    • Using a single MOSFET for switching between USB and battery voltage is just too janky.
      • Shoot through voltage.
      • The way to do it simply would be by taking advantage of the \"Zero Gate Voltage Drain Current\", but there's a load connected to the source so the voltage probably wont rise
      • In-rush current, you need a resistor to the gate
      • Going to need more robust circuitry than this
      • Could flip the P channel enhancement mosfet to have the current go from source to drain in order to get the negative voltage, but too janky
      • Going with a BQ2407x that handles power switching and battery charging. It's basically designed for this exact thing.

    • Not using RT9080. Need a buck boost. I should be able to use the entire range of battery
