Hi All,
On a whim I submitted for the Framework Mainboard Developers program and got selected to get one of the main boards, with the goal being to build a ruggedized (If impractical for day to day usage), Framework laptop.
I’m a member of the Waterloo Rocketry team (you can check us out here: https://www.waterloorocketry.com/). Each year we drive down to the New Mexico desert to launch, where it is both very hot and bright. In addition we also test constantly throughout the year which means plenty of testing outside through the Canadian winter.
All of our simpler ground systems are built into pelican cases and handle the weather just fine, but recently we’ve started doing more interesting things with data acquisition and visualization, which means needing a computer outside. Our little ThinkPad has held up admirably, but just isn’t built for all weather, and so we need a better solution.
This is where the Framework Mainboard comes in. We’re early in the stages of planning out the project, but the general idea will be to build a laptop into a reasonably large pelican case that can handle anything we can throw at it, with the framework at it’s heart.
I’ll try to post more about some of the specific requirements later, but some features we need / plan to include are:
- Large battery for long outdoor life
- Very bright display, since it needs to be readable outside in the desert
- built in Wi-Fi router to support adjacent wireless equipment (I saw a post about turning a framework into a router, that would be really cool to incorporate, but is likely out of scope.)
- A couple of “Payload Bays”, essentially the big brother to expansion cards. The idea is that systems such as our high powered radios used for communication with the rocket can be mounted into the laptop, and swapped out as needed, just like an expansion card.
There are two big challenges I’m hoping to overcome in terms of mainboard mods with this project. while we could use the USB-C ports for power and video, we really want to leave those free for payloads. As such, I’m hopping to use the battery and display connectors on the mainboard for their original purpose.
-
Has anyone ever tried using a completely dissimilar display on a framework mainboard? the connector is eDP and seems like it might just support other displays with no mods, but I haven’t found anyone who has done this, the closest being a thread here where someone managed to use a very similar to stock, but matte display.
-
Has anyone every tried using the battery connector with a different battery? looking at the pinout I take it there is some sort of smbus interface, which means it expects the battery to be somewhat intelligent. Maybe it would be possible to salvage the BMS off of a pack but use it with larger cells?
I’m curious to hear if anyone has any questions or thoughts about this project, I will do my best to keep this thread updated as the project progresses.
