CRKBD Build with Holy Panda Switches and an IMK Case

If you’re a fan of mechanical keyboards, you know that the switch type and case can make a big difference in the typing experience. In this post, I’ll share my experience building a keyboard with lubed and filmed Holy Panda Invyr switches on an IMK Corne case.

What are Holy Panda Invyr Switches?

Holy Panda Invyr switches are linear mechanical switches with a smooth, consistent actuation force. They’re known for their smooth travel and satisfying spring sound, making them a popular choice among keyboard enthusiasts. In addition to the smooth action, the Holy Panda variant of the Invyr switch is known for its slightly heavier actuation force and a more pronounced spring sound. Lubricating the switches can make a big difference in the feel of the keyboard, and adding a switch film can help to further reduce friction and improve the overall typing experience.

Building the PCB:

  1. Start by gathering all of the necessary components, including the PCB, diodes, switches, and keycaps.
  2. Place the diodes on the PCB, making sure that the black stripe on each diode is facing the same direction as the stripe on the PCB silkscreen.
  3. Next, place the switches in the PCB, making sure that they are oriented correctly and that they snap into place.
  4. Once the switches are in place, you can install the keycaps onto the switches.
  5. Finally, you can connect the PCB to your computer using a USB cable, and use the QMK firmware to customize the behavior of your keyboard.

Keep in mind that these are just general steps, and the specific assembly process may vary depending on the specific PCB and components you are using. If you need more detailed instructions or encounter any issues during the assembly process, you may want to refer to the documentation provided by the manufacturer or seek help from an experienced keyboard builder.

Have LEDs?:

If your Corne Keyboard PCB includes LEDs, you will need to install them during the assembly process. Here are the general steps for adding LEDs to a Corne PCB:

  1. First, gather the necessary components, including the PCB, LEDs, and resistors (if required).
  2. Locate the designated LED pads on the PCB. These are usually indicated by small circles with “+” and “-” symbols next to them.
  3. Place the LEDs onto the PCB, making sure that the shorter leg of the LED is aligned with the “-” pad and the longer leg is aligned with the “+” pad.
  4. If your PCB requires resistors, place them onto the PCB according to the manufacturer’s instructions.
  5. Once all of the components are in place, you can use a soldering iron to attach them to the PCB by melting a small amount of solder onto the pads.

Conclusion:

Overall, I’m really happy with the way my keyboard turned out. The lubed and filmed Holy Panda Invyr switches feel smooth and satisfying to type on, and the IMK case corne PCB is a great platform for customization and experimentation. If you’re interested in building your own keyboard, I highly recommend giving these components a try.

I hope this helps! Let me know if you have any other questions.

Corne Keyboard – The Perfect Keyboard for Gamers and Typists!

Two IMK Cases
Corne Keyboard with RGB lights

Hey everyone! I recently picked up a Corne Split Keyboard and I’m loving it so far. For those unfamiliar, the Corne is a mechanical keyboard designed by Foostan. It’s meant to be more ergonomic and comfortable to use than traditional rectangular keyboards.

One of the things that really sets this keyboard apart is its customizable RGB LED lights. You can choose from a wide range of colors and patterns to suit your style. I’ve been having a lot of fun playing around with different lighting setups.

In terms of the actual typing experience, I decided to go with “lubed” Holy Panda key switches. These linear switches are known for their smooth and responsive feel, and they definitely don’t disappoint. I’ve been using the Corne for both typing and gaming, and the Holy Pandas have been great for both.

The Corne Split Keyboard has gained a lot of popularity among mechanical keyboard enthusiasts due to its unique design and customizable features. If you’re interested in learning more about the Corne, there are several resources available online that can provide additional information and reviews.

One great place to start is the official Corne Keyboard repository on GitHub, which includes detailed documentation on the keyboard’s design and features. You can also check out the r/Corne subreddit, where users share their experiences and tips on using the keyboard.

Additionally, there are several online stores that sell the Corne Keyboard and its components, such as KeyHive.com and MechanicalKeyboards.com. These stores often have a wide selection of key switches and other customization options available for the Corne.

Flashing your Corne Keyboard Using QMK

To flash custom firmware onto the Corne using QMK, you will need to have a few tools and components ready. These include a USB-to-serial adapter, a soldering iron, and a computer with the QMK toolkit installed.

Once you have everything set up, you can follow the instructions on the QMK website to compile and flash your custom firmware onto the keyboard. Flashing custom firmware can be a bit technical and time-consuming, but it’s a great way to fully customize your Corne Split Keyboard and make it truly your own.

Throwing the DJI Drones in the Air!

Today we’ve got my Dad’s DJI Mavic Pro and My DJI Mavic 2 Zoom getting ready for their flight today. Starting things off by going over our flight plans and safety procedures. In my younger years I’d go flying with my Dad out in Castroville. I never got a chance to fly with him due to my inability even pilot an RC car let alone small aircraft.

DJI Drones Preflight
Mavic Pro 2 on left and Mavic Pro on right

Well now we have DJI Drones and don’t need to go to the flying field like we used to be required to do 20+ years ago. The irony in it is now I am teaching him how to fly a drone. Which btw after 35+ years of flying Remote Controlled aircraft he was still flying the Mavic Pro like it was a plane!

RC Planes back then didn’t really have any of the safety devices and or assisted flying modes. If not all of DJI drones have the ability to fly with GPS lock allowing the pilot to focus on getting better video. Or even providing a more stable aircraft for first time pilots to fly.

Nani Falcone Park Flyover San Antonio, Texas

3DR Solo Soaring The Skies!

I took this photo with my GoPro Hero 4 Black attached to my 3DR Solo @ Nani Falcone Park in San Antonio, Texas. We just had a big storm on February 20th, 2017 and I was curious as to what this creek looked like after all that rain and wind! The 3DR Solo has a GPS upgrade by a company named mRo and they sell a few aftermarket parts for the 3DR Solo. There are a lot of other Quadcopters out there hovering around but the 3DR Solo is one of the cheapest with the most range of features that you’ll find on a Hobbyist Drone. Unlike many other Multi rotors on the market this one can be modded quite a bit. You can find all kinds of sensors and cameras to make Land Surveying a breeze.

I like that the 3DR Solo offers a range of what they call “Smart Shots” which allow you to do things like take a Drone Selfie or Orbit your selected target and it does this all automatically. Of course you just have to press one button to return your 3DR Solo back to its default flying mode. Each flight can last up to 20 min which of course is affected by the external conditions such as wind, rain, temperature and how the pilot (YOU) fly your aircraft.

Check Out My 3DR Solo Modifications!

3DR Solo Quadcopter & Mods

I just picked up my 3DR Solo this last week and have been flying it whenever I get the time. I also wanted to register with the FAA since it only costs $5 to do so. I am now licensed to fly legally, and will soon be getting my Part 107. You can contact us with questions here.

If you still hurry you might be able to purchase one from Best Buy or another local Computer store, if you already own a GoPro you should definitely pick up while you still can. I will upload some more mods as I do them, so far I plan on upgrading the GPS, HDMI cables, and adding some Moon gel.

You can use your cell phone to view the live video feed that is streamed from the 3DR back to you on the ground, but I decided to upgrade to a tablet instead. I decided I needed one with good battery life and it must have GPS in order for the “Smart Shots” to work. So I went with a Lenovo Tab from Amazon, it works really well and its much easier to plan out missions on. However there are many compatible tablets that can be used such as the ever popular iPad lineup

Time For some upgrades!

I decided to use my #Flashforge 3D Printer to print out some upgrade parts from Thingiverse. I went with a new Gimbal clips that prevents the GoPro from falling out of the Gimbal while your flying. The clip that comes installed from the factory requires that you remove the GoPro in order to remove your Micro Sd Card.

The picture shown on the bottom right shows a simple upgrade that can be 3D Printed if you know or have your own printer, it allows you access to your Micro Sd card without the need to remove your GoPro.

Carbon Fiber Gimbal Clip for the #GoPro on the 3DR Solo, download from thingiverse http://www.thingiverse.com/thing:1479896

If your running the 3DR Solo with a Gimbal like I am you might also want to consider some leg extensions, that will help your GoPro & Gimbal clear the Grass or any obstacles low to the ground. They are easily installed, all you need to do is remove the old clips and snap these in their place!

Quadcopter Build On Father’s Day

So Father’s day was last week and I decided to build my Dad a new 250mm Quadcopter so we can finally race each other. I wanted to make a build video but went with a Time-lapse of the build and its pretty cool IMO. I still need to test fly it and finishing the PID tuning. So far I have some issues when trying to spool up the motors, I am going to troubleshoot it this week. Click HERE to find out more info on your own custom Quadcopter Build.

Using my Flashforge Creator Pro 3D Printer I was able to make some custom parts for this FPV Quadcopter, one of which is a low profile spacer that allows you to put all of the electronics inside the frame including the ESC’s which makes for a super clean build as show below.

The Flight Controller is running Cleanflight but I might switch it over to Betaflight, I still need to look into the recent changes of both Cleanflight and Betaflight.

Its running:

  • Skyline32 Flight Controller
  • FlySky TH-9 Transmitter
  • 2500mah LiPo Battery
  • Carbon Fiber 250mm Quadcopter Frame (ZMR250)
  • Power Distribution Board
  • 2000kV motors

Soon I will be posting a test flight video of this aircraft.

Building A Sub 250g Carbon Fiber FPV Quadcopter

Most of you know that the FAA has stated that all multirotors that weigh more than 0.55 pounds must be registered in order to prevent fines upwards of $250,000. So there has been an increase in sub 250g Quadcopters and Tricopters. Well today we are gonna talk a little about my FPV Quadcopter and what they look like.

My personal FPV Racing Quadcopter that is under 250 grams!

The frame I chose for this build is an: LHI 210mm Carbon Fiber Frame : Overall I am very pleased with the quality of this frame, very sturdy and lightweight coming in at 70g with all the aluminum hardware. In the future I will be using my Flashforge Creator Pro to 3D print some much lighter spacers to replace the metal spacers that come with the LHI frame.

During this build all of the wiring was done in a minimalistic fashion, I would measure the wire bundles allowing just enough wire to go from A to B then add about an inch to allow for some slack.
