[@markrichards5630]

Mainly because you can spend just a ton of $ on brands like Logitech and Razer and they won't do all you need - Razer's won't do continuous presses then release of command key combos and Logitech's aren't compatible with many OS's. I have a whole collection of branded keyboards from trying to get one that could do all I needed in SolidWorks. Making one was the only way.

80% of the time it works all the time 😂 dude you made me laugh so many times throughout this vid, and have also convinced me to start a project like this of my own since I have an Arduino Pro Micro laying around from an old NES Controller conversion project. I really like the implementation of a knob, especially for video and photo editing, I've looked at the more expensive off the shelf products and also think "I could make that for less" but I know it'll cost more in the end haha. Great vid and project, I've subbed 👍

[@RetroBuiltGames]

I appreciate the kind words!! Now that I've have some time with it, the dual knobs are wondrous for video editing. Zooming and skipping through the timeline are meant for encoder knobs.

The guy at my office who does the 3D printing wired up a bucked with uv led strips encircling the inside. He puts the parts in there for 5 additional minutes prior to cleaning to maximize curing.

[@RetroBuiltGames]

Ryan's Pro Tips for navigating the and HID library commands. =============== Keyboard Control================================================================================ Keyboard.write(); Sends a keystroke to a connected computer. This is similar to pressing and releasing a key on your keyboard. Will send a shift command if applicable. Example: Keyboard.write('K') will automatically do SHIFT + k. Can also accept ASCII code like this: //Keyboard.write(32); // This is space bar (in decimal) Helpful list of ASCII + decimal keys: www.asciitable.com/ Keyboard.press(); Best for holding down a key with multi-key commands; like copy/ paste This example is [ctrl] + [shift] + [e] //Keyboard.press(KEY_LEFT_CTRL); //Keyboard.press(KEY_LEFT_SHIFT); //Keyboard.press('e'); //delay(100); Keyboard.releaseAll(); Keyboard.print(); Sends a keystroke(s) Keyboard.print("stop using aim bot"); //types this in as a char or int (not a string)! Keyboard.println(); Sends a keystroke followed by a newline (carriage return ) Very practical if you want to type a password and login in one button press! SOMETIMES, applications are coded to recognize Keyboard.press() and not Keyboard.write() and vice versa. You might have to experiment. =============== Mouse Control=============================================================================== Mouse.move(x, y, wheel); Moves the mouse and or scroll wheel up/down left/right. Range is -128 to +127. units are pixels -number = left or down +number = right or up Mouse.press(b); Presses the mouse button (still need to call release). Replace "b" with: MOUSE_LEFT //Left Mouse button MOUSE_RIGHT //Right Mouse button MOUSE_MIDDLE //Middle mouse button MOUSE_ALL //All three mouse buttons Mouse.release(b); Releases the mouse button. Mouse.click(b); A quick press and release.

I would love to buy one of your PCB's. Living in Australia with $20 shipping made me cry. This is exactly (with so many extras! WOW) what I was looking for.

[@RetroBuiltGames]

Yeahhh, the U.S. Postal Service wont let you put a PCB in a envelope (for international shipping) and call it a letter (that's the ~$3 ship rate) . It has to be marked as a 'package' which is stupidly expensive for flat items weighing 2oz max.

I decided to do this recently, and I just came across a DIY design on Thingiverse that includes linear potentiometers for use as a stream deck. Pretty cool stuff. You mentioned that you use Eagle for PCB design, and I am curious if you have used Kicad. I have been using it for years now and I would choose it over Altium for most design work. It is incredible, powerful, free and open source with no limitations on board sizes and no lock in to a license that is at the whim of the current copyright holder. I love it and I recommend anyone doing PCB work to look into it first.

[@RetroBuiltGames]

I want to use KiCAD. this project started in kiCAD but I got stuck and fell back into Eagle just because i know it well. I know Eagle is inferior; I'm not a fan of Autodesk either.. I will learn KiCAD in 2021.

Would be nice if you could program the face of the keys.. a small oled or e-ink screen on each key. But maybe gets too expensive. An alternative would be a version with a touch screen. But maybe you can use a phone or tablet then just as well somehow coupled to the PC.. Its a bit nicer with real keys. And maybe regular stickers can solve it in the end much cheaper..

[@RetroBuiltGames]

the mini (which is a spin off of this), is still in stock. www.tindie.com/products/21799/

[@liszcgsedt]

Mini USB connedctor is superior Why and by how much? From my perspective, I have a bunch of spare micro USB cables (as phones have switched to USB-C) around and that has been the deciding point for me so far... And yes, when testing a keyboard the other day, I screwed up a pin HIGH/LOW state (basically, I forgot that the LOW is not necessarily 0, ignored a pull-down resistor, I think, for which reason the button was always considered HIGH) and ended up with Arduino emulating CTRL+N 10 times in a second. It took me half an hour of frustrating attempts and reboots to upload a harmless blank sketch before the circus began over again (hint: use an OS where you can pin a window always on top of the others and swear a lot in the process, in my case that helped). :D Also, many years ago (pre-Arduino/RasPi time) the boss button was a thing. I think there was a small commercial solution of a button or pedal along with a small app to define the button macro. Now I am thinking of making a set of cardboard steering wheel (with MPU6050 and two buttons) and a pedal for a car racing dame. Neat!

[@thelightwielder]

[@B_aka_Scias]

how does this rotary encoder feels compared to a mouse wheel? 👀 like, if you place it sideways would it be able to rotate freely? 👀👀 or is it too stiff?

[@RetroBuiltGames]

It would work, but it's bulky. The lateral forces might shorten the life. It's also kinda stiff; but that varies with the make/model, The encoder like most (not all) scroll wheels has pits/ that it will lock into so it doesn't spin freely. You can mitigate the stiffness by increasing the radius of the knob, but again, bulkiness.
