• Day 30: evezor_edgeboard_ftdi_breakout

  anfroholic • 10/15/2023 at 12:33 • 0 comments

  This board uses the standard 6-pin JST-SH connector and breaks out the rx and tx pins and adds 2 bottons for reset and boot pins.

• Day 29: evezor_arm_v1_idc_regiggerer

  anfroholic • 10/13/2023 at 12:39 • 0 comments

  This boards incorporates two gadgeteer ports intended to work with the other devices in this ecosystem. I originally created this board as a way to remap pins. And using this thing I decided that I hated everything about systems like the gadgeteer standard, pmod, shields, hats, and many of the other systems that intend to create a reusable set of standards among controllers and devices. But inevitably you run into issues like, this pin does not have pwm and I want it to. Or this pin does not have pullups or can only be used as an input and on and on. Secondly, when you end up going through these mappings your code and schematics begin to look just as ugly and trying to trace down issues when you want to change or diagnose things you must again untangle all these mappings. No more! I threw all these boards in the trash and have no intention of looking back. It's a noble goal to try and create some kind of standards for breaking out pins and I will continue to create and use them, but attempting to have a paradigm like this as the foundation is untenable and was part of the inspiration for the larger Evezor edge board concept.

• Day 28: evezor_arm_v1_mosfet_thing

  anfroholic • 10/12/2023 at 06:58 • 0 comments

  This board has a few mosfets intended to be used for relays, small fans, lights and other small loads.

  It incorporates a gadgeteer port to work with the mainboard who's source can be found here: https://github.com/evezor/evezor_arm_v1_mainboard_V2

• Day 27: evezor_arm_v1_mainboard_V2

  anfroholic • 10/11/2023 at 10:07 • 0 comments

  This is the second iteration of the mainboard. The first version can be found here: https://github.com/evezor/evezor_arm_v1_mainboard_V1

  This board retains the Molex KK connectors for the stepper motors and the gadgeteer ports for expansion.

  This version also incorportates a stepdown voltage converter, a power relay and a pair of USB-A ports inteded for powering a raspberry pi and a screen.

• Day 26: evezor_arm_v1_spi_power_board

  anfroholic • 10/09/2023 at 04:12 • 0 comments

  This board is inteded to be used with the evezor_arm_v1_mainboard_V1 https://github.com/evezor/evezor_arm_v1_mainboard_V1

  It adds a power input for all 5V needs, it adds an sd card and associated ciruitry and an rj45 port that connects to the arm nano board

• Day 25: evezor_arm_v1_mainboard_v1

  anfroholic • 10/08/2023 at 01:53 • 0 comments

  This board is based on the RAMPS1.4 Board https://reprap.org/wiki/RAMPS_1.4

  The motor connectors have been changed to Molex KK connectors and the extra pins are broken out in the Gadgeteer Standard pinout

• Day 24: evezor_arm_v1_sleeve_protoboard

  anfroholic • 10/06/2023 at 10:23 • 0 comments

  This board was intended to sit at the elbow of the robotic arm and serve as a prototyping area to create new ciruits. It has a 10 pin IDE port to connect gpio to the sleeve controller board, but this avenue was abandoned as there were many issues keeping things simple.

• Day 23: evezor_arm_v1_sleeve_powerstep_board

  anfroholic • 10/03/2023 at 04:12 • 0 comments

  This board was intended to sit at the elbow of the robotic arm and serve as a power distribution point and a place to plug in extra stepper motors when extra axis are wanted.

• Day 22: evezor_arm_v1_nano_sleeve_board

  anfroholic • 10/02/2023 at 05:44 • 0 comments

  This board was intended to sit at the elbow of the robotic arm and its primary function was to obtain and smooth readings from the encoders and to drive the neopixel arrays at each joint.

  It also featured 2 ide ports that followed the Gadgeteer standard which I found to be a less than satisfactory attempt at creating modular systems. More on these reasonings can be found in some of my other posts.
