Raspberry Pi 400 Retro Keyboard

Raspberry pi recently announced its latest model of the Raspberry Pi. It's called the Raspberry Pi 400

It's not clear that it is available for purchase yet. I heard about it first from a podcast called SQPN that discusses technology. 

It is basically a Raspberry Pi put into a keyboard, so the Raspberry Pi 400 is the same as the Raspberry Pi 4 but with upgraded parts. It runs the latest version of Raspberry pi OS. The $100 kit includes the following:

  • Micro HDMI to HDMI cable (for monitor display)
  • Power cord 
  • Micro SD card (for the OS and storage)
  • Mouse
  • Raspberry Pi project book

It's also really cool because the ports on the keyboard are located in the back:

I will write a follow-up blog post when it arrives! 

Here's an example of a real retro keyboard with a built-in computer from the 1980s. It was called the Commodore 64. The Commodore had 64 Kb compared to the Raspberry Pi 400 that has 4GB of RAM. My Dad was in high school when the Commodore came out, and he remembers one classmate who had one, but no one else had one in his class. These movies came out the same year as the Commodore:

  • E.T.
  • Annie 
  • Star Trek Wrath of Khan 
Here are some old ads for the Commodore:


Two Saturdays ago was "yard sale day," and my Mom, my little sister Sophie, and Johanna went garage sailing with my friend Adrian's family, and one of the things that Adrian got was a free hoverboard. I had assumed that this hoverboard was broken, so I asked if I could borrow it to try to fix it. And Adrian had agreed, so later that night, I began taking the hoverboard apart. I had checked the battery level with a power level indicator, and it had said that it was full, so I realized that the problem is between the power switch and the battery. And my brother Gideon found out the problem. It was that the power box cable wasn't plugged in. Once I plugged it in, the hoverboard turned on! I reassembled the hoverboard and took it outside, but it kept beeping with a red light when I turned it on. After a bit of googling, I found a video showing how to reset the hoverboard. I tried it, and it worked! I gave it back to Adrian the next day.

Ender-3 Has Arrived

Yesterday the Creality Ender-3 arrived. In a post I did last week. I explained that I had ordered an Ender-3 off of eBay. It took about a week to arrive. I was excited to open the big box and start assembling. Assembling the printer was easier than I had expected, after a few bumps of assembling and taking apart I finished, and it took me about an hour to two hours. It came with sample white filament and a couple of simple 3d models, so I started a sample model of a dog and went to bed. The next morning, I took the dog off the print board, and I was surprised it printed quite well. The top of the dog's head messed up a bit, but that was because the filament sample roll had become loose at the end. I can't wait to start printing! Here are some pictures of the new printer next to the old printer:

Using an iPod Touch as a OctoCam?

On my last blog post, just as I was about finished, I found a link to my old blog post called "PrintrBot," I noticed that in that blog post, I had taken a time-lapse video of a print. It looked better quality then the Octoprint camera I have now, so I thought it would look better if I could use my old iPod touch for the Octoprint camera. I did some googling and found a forum asking the same question, and the answer was yes! You could use an iPod or iPhone as a camera for Octoprint. So I followed the steps. The first step I did was go onto the App Store on the iPod and found an IP webcam app and downloaded it. Once that was done, I opened the app. It showed the IP address I needed to go to to view the live stream. And then I hopped back onto my computer and typed in the address. It had worked. It showed the camera feed from the iPod. So far, so good, then I went to Octoprint and installed a plugin called multi-cam, a plugin for monitoring separate cameras and quickly adding webcams to Octoprint. Once that was done, I added a new camera and typed in the IP address, but it did not load. The reason was (which I found out a few frustrating hours later) because the IP had linked to a place where it had settings and other stuff but what Octoprint wanted was the Video stream direct IP instead of a site with a ton of controls. The way I got the direct address to the video stream was by right-clicking the video feed and then clicking "Copy Image Address." and pasting that address into the stream URL on the multi-cam control panel, and it worked now I can use both cameras. Here is a picture of the control panel with the iPod video stream on:
