Reid's For Fun


My personal blog for what interests this computer guy. Web development, LEGO ray tracing, ZX81 retro computing, writing and photography.

Entering a Program Shouldn't Be This Frustrating

Back in July, I made a mistake and entered in Star Probe again. I had forgotten that Iíd already shared it. But, unlike my first attempt, I had taken a different approach which made it a much different game. Jumping ahead, I decided to finish what I started. Here is Star Probe Redo, an updated version as Octoberís program.


Here Is a Silly Test Program for the ZX81

September proved to be a rather busy month, at work and home. It isnít unusual for me, and I usually find time to throw a render or program together. As this month closed, I found myself in need of a program to share and not a lot of time. While cleaning up a few things on my laptop, I found this little test program I wrote last month that fit the need.


Here Is My Crazy Idea to Make a ZX81 Game with a Printer

Back in the day I learned to program on school PDP-11 with a 6 teletypes and a CRT attached. I was still in computer club at the time, thinking the 8" floppies were pretty cool. To my despair, the poor thing died that Summer and, when I took my programming class, it was on an Atari 800. But the programs I wrote the previous year stuck with me. Printer Car harkens back to those days.


Now Is a Good Time to Build My Mini ZX81

A retro blast from the past! The four chip Sinclair ZX81 was the first computer I owned and I thought it would be fun to build a LEGO version of it. The 2K of memory (in my US version) was pretty limited. An essential accessory was the 16K RAM which allowed you to fully use the screen and enjoy some fun, if blocky, games.


Adding a New Topic Category: LEGO Building

LEGO Building

I haven’t added a new topic in awhile, but I ran into a bit of a problem lately. As an AFOL (Adult Fan of LEGO), I recently got back into building with real LEGO bricks. In doing so, I decided to start taking pictures of some of the sets of been building. Not content with building official sets, I started to build MOCs (My Own Creations) from both myself and others. I needed a place to share.






More May Fun With Blender And Lego Bricks

I’ve been having a lot of fun in May, rendering images and trying out some new techniques when I can. I’ve also been trying to learn Blender, work on decorations for old models, and try out new sites. Although still learning, here are four of the renders I made during the middle of the month.
