Commodore SX-64 Restoration element14 presents  |  Matt Eargle's VCP Profile |  Project Videos   One of the finishing touches that got cut from the Project Essex Commodore SX-64 restoration video on element14 presents was replacing the "transit card" (officially known as the "Head Vibration Protector") from the 1541 floppy diskette drive. The transit card is a specially-shaped piece of heavy card stock that slides into the disk drive and holds the head assembly in place t ...
  My friend Jon Esparza (@jonscrazytweets) discovered a rare Commodore SX-64 while going through his late father's storage unit. Knowing that I was a retro computer enthusiast, he gave me a call to see if I was interested in doing something with it. So of course I took a road trip to south San Diego to see this "Commodore laptop" in person (and get some bomb tacos)! Jon was kind enough to let me take this Commodore SX-64 off his hands and see if I could get it in any better shape than it's ...
Commodore SX-64 Restoration element14 presents  |  Matt Eargle's VCP Profile |  Project Videos     In my quest to restore the Commodore SX-64, my first obstacle was the lack of video signal on the internal monitor. I needed to diagnose the Commodore SX-64 video signal before I would be able to move on to any other Commodore SX-64 repairs. In this video, I will go through the process to diagnose a Commodore SX-64 blank screen and step through how to repair a Commodo ...

Commodore SX-64 Restoration element14 presents  |  Matt Eargle's VCP Profile |  Project Videos     The Commodore 1541 floppy diskette drive is notorious for breaking down. The Commodore SX-64 floppy drive is no different. As I continue my Commodore SX-64 restoration, I find that the 1541 floppy drive doesn't read diskettes any more and makes a chattering sound when attempting to read a disk. In this video, I walk through how to diagnose the SX-64 floppy drive as we ...
Commodore SX-64 Restoration element14 presents  |  Matt Eargle's VCP Profile |  Project Videos     The Commodore SX-64 keyboard is usually the first thing to fail on these old systems. As such, I need to repair the keyboard on this SX-64 restoration. To begin, I'll need to DIY an SX-64 keyboard cable from a 25-pin serial cable. I'll use the SX-64 replacement keyboard cable to diagnose problems with the membrane keyboard itself and resurface the SX-64 membrane keybo ...
Commodore SX-64 Restoration element14 presents  |  Matt Eargle's VCP Profile |  Project Videos     I was having a little trouble working on my Commodore SX-64, trying to diagnose a blank screen, so I needed to attach the Commodore 64 to a TV. Unfortunately, with these retro computers, the cables seem to vanish into the dustbin of history. So, to fix my borked Commodore SX-64, I needed to hack together a DIY Commodore AV cable. This 5-pin DIN AV cable is compatible ...

Radio frequency

Posted by olivercohen Jul 30, 2019

My question is if I take an aerostat ballon to 400m high Place a antenna attached to a tracker  To always send the waves to the vehicle. Will that work? Also how do I  tranmit to the aerostat antenna from the ground control 400m down ? Any ideas? ...

Arduino Retro LED Matrix Handheld element14 Presents  | AirborneSurfer's VCP Profile | Project Videos   The matrix circuit for Project Hawthorne is a little different in that it's all NPN transistors instead of the "simpler" combination of a shift register and decade counter. I feel like this is less abstract and easier for a novice to understand.   ...
