One thing that bothered me was that I needed to switch WiFi networks every time that I wanted to use the UniJoystiCle. Not a major issue, but not ideal specially if you use your phone both for the UniJoystiCle and for “regular” stuff.
To solve that issue, I added WiFi Station mode support (Access Point mode is still supported). Basically the UniJoystiCle WiFi device, when in Station mode, can connect to any WiFi network. It also supports WPS (an auto-auth way to connect to a network). If Station mode fails, it will default to Access Point mode.
In order to switch to Station mode you have to:
Install firmware v0.4.3 (see below for more info)
Boot the UniJoystiCle WiFi device (it will boot in Access Point mode)
Select “Station” mode, put the credential (SSID and password) and reboot!
From http://unijoysticle.local you can also configure the “Inactivity timeout”: how many seconds without activity should elapse before all the joystick lines are set to Low (simulates no joystick movements).
I also added statistics: It tells you how many seconds you spent on the different joystick positions, and how many movements you did. Useful, right? 🙂
As the name describes it, it was a Commodore Expo in Las Vegas. But the format is a mix between conference and expo. It is a real expo, but with the social part of a conference. It is friendly and casual.
People give talks in a very informal way. I gave a talk + live demo about the UniJoystiCle. Everything went well except that in the middle of the demo my phone’s glass broke. But that wasn’t an issue since the accelerometer kept working.
Commodore 64 works Ok when the UniJoystiCle board is unpowered. The issue was that the 4066 chips were in an unknown state when they were unpowered. In v0.2.1 the 4066 ICs get power from the C64 Joy #2 port
Smaller holes for the DC Jack making it compatible with “common” DC Jacks.
I assumed that the Commodore 1581 was failing because of a bad WD1772 IC (as documented in Part I). So I ordered a WD1772 replacement + the IC socket, I developed some basic desoldering skills, watched some desolderingvideos, and also got a cheap desoldering iron from Radio Shack:
So, I removed the board from the Commodore 1581 and started to desolder the IC. To my surprise the $11-buck desolder iron worked pretty well. I was able to remove all the solder from the the pins in a few minutes. The desolder iron just takes some time to reach the needed temperature, but besides that, it seems to be a great tool for occasional desoldering tasks (a hobbyist desoldering iron cost more than $250)
