We already soldered one SMD kit, which allows you to practice the difficult task of soldering surface mount components. Now we try another kit with a bit more difficult components: two QFP44 ICs are in the kit as well as the usual array of resistors, capacitors, diodes and transistors. I will show you some techniques and tools for this job and hopefully we get better at soldering SMD stuff!
The demoscene has been part of Amiga (and PC) culture for at least 30 years. Of course there are still great demos and intros released for all kinds of platforms. I love when the Amiga OCS machines (A500, A1000, A2000) get some kind of love, but getting a brand new demo ONLY on floppy disk, and not for download, is something special. This is Hologon by TEK (The Electronic Knights) — let’s watch it!
In the last episode we learned how to code the rotozoom effect using floating point arithmetics. This however is pretty slow on ancient DOS machines, like 486 and even worse on slower machines. So in this episode we will rewrite the program to use integer based fixed point arithmetics.
