So I was having issues flashing my Elite-Cs for a while but with some time away from the project and some help from discord I discovered two key problems. One of my MCUs was mounted to the wrong side of the PCB and that was screwing everything up. The...
While waiting for a replacement board I decided to do a little more redesign of the system. Currently the mainboard cooling fan is a 24-volt fan, and the two fans on the extruder for the heat break and part cooling are both 5-volt fans.The SKR 3 has...
Project Log 10: 18:05 hours - Brasilia Timezone - 2 of OctoberGreat news that I forgor to talk about: I got more printers and even more printers are coming!These few days have been quite... Agitaded for me. I got some new tools...
Ventilation & Carbon dioxide: Good ventilation is important for indoor air quality, especially for reducing the concentrations of pollutants and airborne viruses (looking at you, COVID-19!). Measuring carbon dioxide (CO₂) can be a useful proxy...
Alright, I know what you're thinking. It seems pretty early to be painting, and you're right. In truth, there was a bit of test fitting before the paint stage, but probably not nearly as much as you'd think.Like the keyboard fitment, the painting...
I knew early on that I wanted the deck to use USB-C Power Delivery, as over the last couple of years I've switched most of my personal devices over to the standard. Luckily, so-called "trigger-modules" are easily sourced online that will handle...
I always wanted to build a cyberdeck, and when i saw the contest i wanted to say "Hi guys! I'm here too! I love cyberdecks!!!"I had an old Pine64 with its lcd display laying around and a bluetooth keyboardSo, after many doodles, many 3d designs and print...
By using precise scientific approach and materials (i.e. a bit of foam board and a few nails) I "designed" a mechanical linkage which can move between two required positions. Based on that I added a bunch of holes in the keyboard case and a few holes...
A few words about the (messy) insides. Initially I started with the idea of planning and placing every bit in 3D software. Very soon that transformed into hot-gluing things in place which then turned into "just cram it all inside and hope to be able...
The final step was to adjust software. In the end I decided to go with terminal dashboard for the main view (using wtf dashboard https://wtfutil.com/), plain terminal for the terminal view and overlay the pi camera when needed.After editing ~/.config/openbox/lxde-pi-rc.xml...
The Power Supply is made up of a 60W USB C PD powerbank and a pair of USB-C negotiator modules, that negotiate for the 20V@3A (60W) profile.One is connected to the powerbank and feeds the output through two high current diodes to a super capacitor bank...
This project is based on my old 2D-LoRa-Pager idea: https://hackaday.io/project/182465-2d-lora-pagerLoRa did not worked out in combination with the TFT screen. So i used Bluetooth as a fallback solution. 2D Pager upgrade - New: a receiver indicator....
To allow quadrature encoders & all the extra signals on each motor, the new nozzle has a dedicated control board for each motor, with a single wire UART stringing them together. 2 boards are dumb motor drivers which read H bridge bits & write hall...
So my cad skills are still not great, but I'm beginning to understand components and have a loose handle on how to deal with joints. I still need to work out how to make drawings and renders, but that will come. Here is a rough sketch of the space...
COMPONENT CHOICES Servos I used to have metal gears and they are a little bit less crappy than plastic ones. Servos work on 5-6 volts and 18 of them draw around 4 amps constantly while the robot is working. that is why I went with 5A UBEC from hobby...
