Buses in Croatia are, to say the least, dramatically regulated (yes, I am still mild here).
Tickets seem to be sold unlimited, without thinking into account that there must also be a place for all those tickets in a physical bus. What a novel idea, every ticket sold represents at least one seat in the bus?
During the last couple of months I have collected a number of joysticks that need to be tested. I could just connect them to one of the ZX Spectrum computers for testing, but why take the risk if you can easily build a joystick tester .
Also it could come handy when on a fair you want to make sure a particular joystick is in working order before buying it.
In preparation of assembling a TZXDuino (compact) I need to be able to program an Atmel ATmega328P micro-controller.
I have a bunch of Raspberry Pi’3 lying around doing nothing and it would be nice to be able to use one of these Raspberry Pi’s as a programmer unit. After some research there are plenty of tutorials available on how to program an ATmega328P micro-controller (and a couple of other micro-controllers) using a Raspberry Pi.
When I was fixing my ZX Spectrum +2B I could not test the joystick ports since I don’t own any Sinclair joysticks. To be able to use joysticks that use the Kempston (Atari compatible) standard I would have to make use of some sort of adapter to convert one into the other.
There is enough information available on both types of joysticks, so it is not hard to figure out how the pins need to be rewired (See table below). Since the Sinclair joysticks do not support auto-fire or additional fire-buttons only 6 pins (4 directions, 1 fire and ) need to be rewired.
