Yeaaaaaaaaaah! UniJoystiCle v0.3 was released! It includes: A beautifully designed PCB A realistic Unicycle game for the Commodore 64 A the iPhone application which can be downloaded from the App Store The new PCB Either you can: Build one yourself (the instructions are here:https://github.com/ricardoquesada/unijoysticle) or order one from OSHPark: But if are really interested in getting one, contact me and I’ll send you a fully assembled one for free. Just convince why you deserve it. ...

v0.2.1 powered from a battery. Can be powered from USB as well. Changes in v0.2.1: 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. Unfortunately, v0.2.1 has a bug, and the way to fix it is to cut the 3v3 trace that comes from the NodeMCU. ...

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 and the IC socket, I developed some basic desoldering skills, watched some desoldering videos, 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 pins in a few minutes. ...

Download(firmware, iOS client and schematics + board): https://github.com/ricardoquesada/unijoysticle Changes in v2.0: [NEW] - ESP8266 Schematic: PCB board version. Protoboard version deprecated [NEW] - ESP8266 Schematic: Added EAGLE board and schematic files. Fritzing diagrams deprecated [NEW] - ESP8266 device: supports 2 joysticks (uses three 4066 ICs instead of two [NEW] - ESP8266 firmware uses AP mode by default. Uses SSID “unijosyticle” + last 2 bytes of mac address [NEW] - iOS Client: Can be configured to use either joystick port [NEW] - iOS Client: Auto-discover ESP8266 firmware using mDNS [NEW] - iOS Client: UniJoystiCle mode also supports up, down and fire (jump) [FIX] - iOS Client: Uses correct aspect rations in all iPhones: 4, 5, 6 and 6+ [FIX] - iOS Client: D-Pad mode uses arrows + circle instead of colored squares [FIX] - iOS Client: D-Pad mode highlights buttons when they are pressed [FIX] - Name: Renamed project from Uni-Joysti-Cle to UniJoystiCle (easier to search, shorter to type) [FIX] - ESP8266 device: replaced NodeMCU LoLin with NodeMCU Amica since it is breadboard friendly. [FIX] - Sophisticated Glue Material: Uses gaffer tape, instead of duct tape

My Sacred Diskettes. In 1986 (or was it 1987?) I got my first computer, a Commodore 64. I started learning BASIC and during ‘87 and ‘88 I created some very simple games. Somewhere in ‘88 I started learning assembly language (machine language to be precise), but I don’t recall coding any game using this language. If so, it must have probably been due to the fact that I lacked a good monitor. ...

As a kid, I always avoided the Drean Commodore. I didn’t like them because they were not compatible with the NTSC software. As an adult, I really wanted one basically because I’m from Argentina, and the Drean was produced in Argentina. And I want to make sure that all the software that I develop works on a Drean. And in my lastest trip to Argentina I was able to get one :-) The condition of the computer is Ok, neither great nor terrible. It works, although I need to do more tests. Here are some photos: ...

A few weeks ago, we, the Pungas de Villa Martelli, released “¡Arriba las Manos!”, a music disk for the Commodore 64. It includes ten 8-bit songs, an animated hi-res graphic, an easter-egg, and you can control it with a joystick, or a mouse or the keyboard! Not even Apple puts so much love in the UX like us (the future is the c64!) ...

I like Fritzing. I think it is great for small projects and it is very easy to use. But it has its limitations when creating the PCB, mostly because its component library is not very complete. Eagle, on the other hand, is more difficult to use. But its component library is very polished. Also, companies like Adafruit and SparkFun create components for Eagle, so that is a big plus if you purchase components from them. ...

UniJoystiCle v0.2 coming soon. Changes in v0.2: [NEW] - ESP8266 device: supports 2 joysticks (uses three 4066 ICs instead of two [NEW] - ESP8266 firmware uses AP mode by default.
