Setting up Ethernet

I have heard from most computer professionals that ethernet is much better than using wifi for home computers because of the speed compared to wifi speeds. Today, I installed an Ethernet switch underneath my desk. First, I ordered an Ethernet switch from amazon (Amazon Link), and then I also ordered a 15 foot long cat7 Ethernet cable (Amazon Link). Once they arrived, a few days later, I plugged an ethernet cable into the nearby ethernet outlet, then sent an internet signal to another port that I plugged into the port that I labeled "North Room" (which was my bedroom). Then I plugged my Ethernet cable I just ordered into there and then plugged the other end into the switch, which I mounted right below my desk. So far, it seems to work better than Wi-Fi. I wanted available Ethernet ports because I have several Raspberry Pi's that I use for different projects that need to be connected directly using ethernet instead of wifi is because I had issues with my Raspberry Pi. Either the wifi chip inside the Raspberry Pi isn't strong enough, or it doesn't have wifi compatibility built-in. 

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:

Hoverboard?

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:
