Amstrad Papercraft!


Created on: 23-01-2019  By Gee
I was searching about the internet for all things Amstrad a while back and came across rockybergen.com Amstrad CPC 464 Papercraft and I got all excited.
I'd never made any papercraft stuff before but thought it looked pretty cool. Right up my street.
Fast forward to Last week and I remembered about this. I downloaded it onto my work computer (during lunch! honest boss!) and printed it off at the end of my shift onto a4 paper. Sadly the printer in the office only prints in black and white. But I got it printed out and took it home anyway.
Once I got home and the baby was asleep, I set about making this little beast. It was a lesson in... Read More!


Commodore Invasion


Created on: 16-01-2019  By Gee
My Father-in-Law was pestering me a while back to sell some "old computers" for him and I had mentioned at the time that I wasn't so keen on helping as they don't fetch much money.
Now, that was quite unusual for me as I quite like old tech (you'd never have guessed eh!?). But at the time I didn't have the inclination to deal with them.
After having spent so much time watching people fix their old computing equipment on YouTube I thought I'd at least have a look at these computers. I asked if the computers could be looked out and I'd get things set up to get them sold on.

I was told that there was a boxed c64 (more modern style, not a breadbin sadly) with cassette drives and a pair of joysticks. Three or four am... Read More!


Learning to make sprites


Created on: 12-01-2019  By Gee
I was looking through the contents of the cassette that came with the Teach yourself Amstrad basic book and found a blackjack game.
I played it for a bit and found it quite addictive, even with it's lack of graphics, sound or even wording that looked vaguely human.
I was thinking about how I could make it better by using sprites for a few things. Maybe even add some background music and sound effects. This led me to look into how to make sprites for the Amstrad. It took me a good bit of searching and reading to try find something that might work. I was thinking I might need to just remake it all in assembler, but I don't quit... Read More!


555 timer clock


Created on: 31-12-2018  By Gee
The very first part of Ben eater's 8 bit computer is the computer clock. This is made by using a 555 timer, some resisters, capacitors and an LED to show it working.
Each time the LED is on, it represents a clock cycle. This will eventually control the computer cycles in a similar way to how an oscillator works on other computers.
I had another look at the video on YouTube that Ben made and followed it the best I could with the parts that I had.
I used a 220ohm resister instead of a 1kohm and tried various different capacitors for the clock speed.
At first the LED just stayed on and I wasn't sure why. I'm still not sure what caused it, but I fixed it by wiggling a few of the components and wires around.
I'... Read More!


Soldering station


Created on: 31-12-2018  By Gee
I ordered my soldering station and all the paraphernalia a while back as can be seen with the date on my last post about it.
Finally today the last, and main, part arrived. It arrived whilst I was geeking (should that be gee-k ing) around with starting my Ben eater computer.
Obviously, I just had to have a play around with it straight away. I set out my heat resistant mat, which had mega static when I took it out of its bag. I hope I managed to destatic it before working on my raspberry pi.
I tried a couple of different soldering tips before I found one that I can work with. My first attempt at actual soldering was to solder on the header to my pi zero that I want to use for creating and programming things in the future... Read More!
