C64 "Searching for $" Serial Buss issue repaired

After playing with a C64 i picked up recently and the disk drive that came with it, I notcied that loading failed once in a while.. It was not the disk or the drive, because by trying the drive on my other C64 the drive works.

I read online that on the Serial Bus there are buffers with open collector output (7604) and they fail often. I replaced one and, Voilá !

Reverse engineering PCBs with KiCAD 7

In this Article we will be looking at replicating a PCB using KiCAD 7, and it's new Background Bitmap image feature. With the bitmap image feature it is much easier to replicate PCB designs. Before I have used sprint layout and kicad in a complicated process. Capturing images A scanner is hands down the best tool you can use for getting a good result. You can use a camera for smaller boards, but for larger boards you quickly run into problems. Image scaling Because KiCAD 7 not yet have separate x/y scaling, and x and y scaling is not equal usually, you have to scale them separately in a photo editor, like GIMP. When the image is loaded, set the DPI of the image to the same as the settings of the scanner. It is usually 600, but sometimes 1200 (or even 300). When you have set the correct DPI, the ruler tool should yield distances close to the real thing. Find two points on the board in the X direction that you know the distance of.  Use the (GIMP) ruler tool to measure them. Take not...

The Videopac G7000 composite mod

Bilde
   Introduction This is a write-up of my experience with a custom composite mod board for the Videopac G7000 game console, and the mod installation. The write-up is based on my youtube video below (the second one). In this blog post we will demonstrate the installation and picture quality. The sites gamesx and coolretroprojects linked below have installation instructions and schematics. Coolretroprojects sell a board, and they have a nice installation manual in PDF format. Links: http://gamesx.com/wiki/doku.php?id=av%3Ag7000_av#picture_of_g7000_internals http://www.coolretroprojects.com/Mods-Kits.html Videos: Video: Building a circuit for a friend of mine. Video: Installing the composite mod. This is the video you are reading a write-up of right now. Background The Videopac G7000 also known as Odyssey 2, however different internally and different composite mod board for it. The G7000 was introduced to the market in 1978. It has a RF modulat...

Programming an ATTiny85 for low power fridge alarm

Bilde
This project is about a fridge alarm powered by solar cells, and energy stored in super capasitors. It is mostly about programming the ATtiny85 MCU in Assembly. I wanted to learn more about the AVR core. That is why I programmed using assembly language. The program is very short, and the features of C is not needed. The circuit has an AEM SUCA R2 as power supply, an ATTiny85, one IR diode, one photodiode, a 2n7000 NMOS driving a magnetic transducer. Unfortunately in this testing I don't have a microamps meter. I've been monitoring the voltage decent of two parallel capacitors of total 3000uF. Why AVRA AVRA is an assembler for Atmel AVR microcontrollers. It is simple and effective. It's open source. There are examples here at 043-045 that gets you going. Also lately I've been using Linux more and more, and installing AVRA was just a single command line. The program The flow diagram shown above is the whole program. The program checks the sensors every 8 seconds and...
