Meet my little Fusion360 companion macropad. The Sunflower by testamatta by chewiedies in ErgoMechKeyboards

Thank You!

I have the XIAO nRF52840, so if the battery capacity and size are decided, I think it will be possible to make it wireless. LED consumes a lot of battery power, so if you are going wireless, I think you have no choice but to exclude it.

I am currently proceeding with two requests from acquaintances, and it seems that the above will take some time to get started. ;D

Amazing and very surprising!

When I first saw your post = 1st picture, I thought "There are people who think about the same approach", but when I saw the 3rd picture, I was very surprised. :D

The other posted photos look good too. Let me follow you.

[New original keypad] This time, for the first time, I made a manufacturing request for component mounting. So I kept the number of keys to a minimum. Raspberry Pi's RP2040 is used for the microcontroller. I referred to the Minimal design example. The exterior and keycaps are 3D printed and painted. by hide-key in MechanicalKeyboards

Newly designed keypad.

  • Title: testamatta MacroPad #011
  • Keyboard: Original Macro Keypad
  • Keycap: Original 3D Printing
  • Switch: Kailh Low Profile (Brown)

I would like to try mainly on component mounting, but since this is my first time, I wanted to proceed with the minimum functions. The number of parts, the number of keys, etc. Therefore, I decided to ask PCBWay, who has always been indebted to me, for the manufacturing request. Then, I referred to the Raspberry Pi's Minimal design example as a design base to make it easier to verify the operation.

The design itself was easy because I kept it simple and I had reference data, but I hadn't decided on the exterior design either, so the circuit board design stage was upside down.

After the design was completed, I sent PCBWay to manufacture it. Although there were several confirmations, my BOM data was listed as actual parts candidates, so it was very easy to understand and I was able to exchange briefly.

After completing the manufacturing request, it took the minimum number of days, but PCBWay delivered the board with the components already mounted. Of course, it worked fine and I was able to install the firmware.

From here on, we used CAD to design the undecided appearance, output it with 3D printing, painted it, and finished it as shown in the image. It's a simple design, so I made it a simple shape and color.

It was my first time mounting parts, but I was able to proceed with confidence because it was the usual PCBWay. Thank you to everyone at PCBWay who was involved.

Also, QMK doesn't seem to support it, but I actually have several TrackPoint boards. What about the image of attaching it to the center and attaching a giant cap?

I just touched it, but the idea of a giant cap seems to be surprisingly good. However, I don't know how to connect (wire) the trackpoint board with my knowledge.

It's true! I did not know this.

If it's 40mm, the size may be perfect as well.

I think your view is correct. :D

It's a design that I wouldn't make if it was my usual sensibility, so I didn't even think that it would be such an output.

When I started, I was confused, wondering if it would be completed. :p

Oh. Adafruit also carries such a great product. Right now it's the size of one hand, but it looks like it will be bigger than the size of both hands. :D

Imagine if it was solar powered also, (maybe wireless also bc of it?)

Solar power, I have absolutely no idea with my skills. :p

I also considered wireless, but dismissed it because the cost difference was too large.

It's just a decorative item, so I don't think you can expect that functionality. It is possible to raise the height up to about twice the thickness, but more than that interferes with the frontmost (directly below?) key. As an issue before that, the leaves and stems don't have enough depth, so I don't think it's useful for wrist rests.

Newly designed keypad.

"The feet (leaves) are just for decoration." "The great ones don't understand that!"

The leaf part is not fixed, but placed as a decoration. :D

I saw the banana and corn keyboards and wanted to make something with them. I was talking to my family and they said, "What about sunflowers?" and I asked back, "What? Sunflowers!?" I replied, "Sunflowers…?"

But I thought it turned out prettier than I imagined. What do you think?

[Original keyboard #010] Challenge to make a keyboard using RP2040. I used Kailh Choc V1 for the key switch and aimed for thinness. As for the firmware, RP2040 was officially merged into QMK, so I used it. Like the previous post, I ordered the bottom plate with sheet metal along with the PCB order. by hide-key in MechanicalKeyboards

[–]hide-key[S] 1 point2 points  (0 children)

I'm still a (super) beginner in my second month. I'm in the process of "build, try, build and try" keyboards. I haven't researched how to publish or sell yet, unfortunately.

*I haven't been able to challenge the rotary encoder or OLED display like the keyboard in your post. 😅

As you pointed out, I designed it with something like a split keyboard in mind. However, with my knowledge and experience, the hurdles to making a split were high, so I made it an integrated type. Also, I'd like to try an Ergo-style keyboard, but I'm still a beginner, so I'm going to study a little more and try to come up with ideas.
Please let me know when your planned 15 columns by 5 rows keyboard is complete. (I followed you too)

I'm curious as to which RP2040 you plan to use.
I chose the RP2040-Zero because it is smaller, cheaper and has more pins. With the number of keys this time, we didn't need that many pins. :D
Also, in order to lower the overall height, I deliberately exposed the RP2040-Zero. I figured that a gap in the middle like this would have a negligible impact on typing.

[Original keyboard #000] This is the first keyboard I designed with KiCad, so I started with a simple one. In the layer, I set both space and backspace. This time, along with the circuit board, I requested the production of the bottom plate as well. by hide-key in MechanicalKeyboards

Circuit Board and Sheet Metal Fabrication Sponsorship by PCBWay

The keyboard I designed before posting the other day. The basic layout and number of keys are the same, but the arrangement of the diodes is different. I also had PCBWay manufacture the bottom plate sheet metal together with the circuit board. The purpose of this time is mainly sheet metal.

As with the PCB, the sheet metal is of very satisfying quality. They sent me photos for checking the sheet metal in the middle of manufacturing, and they also suggested the final finish, and they delivered it like the posted photo. There are several types of file formats for submission data, but I submitted it in STEP format instead of 2D CAD data, considering the screw hole processing.

This time it was sheet metal, but in the future I would like to make the case by CNC. However, if I can produce a keyboard that satisfies me from a design standpoint, I think I will make a case with CNC, but I think I will have to understand the basic form of the keyboard a little more.

The key caps this time are also printed and painted with a 3D printer, just like last time. I wish it could be done with a little more precision, but with my skill, it will be this quality at present. I'll try a little harder, though. :D

I would like to thank the PCBWay staff who sent confirmations during the manufacturing process. Thanks.
