This document provides updates on multiple projects including a gaming glove Kickstarter, a Wi-Fi modem for the Commodore 64, and a virtual input device. It discusses progress made on prototypes, issues encountered like high component costs, and plans to launch the Kickstarter and sell completed products. Details are given on the Wi-Fi modem design which uses an Arduino, RN-XV module, and OLED display to provide Wi-Fi connectivity and TCP/IP networking to the C64 via its user port. Potential configurations and pricing around $160 are mentioned.

2. 1. Update on the Gaming Glove Kickstarter
2. New project: Wi-Fi Modem for C64
3. New project:Virtual Input Device

3.  Business partner’s family health issues
 Base sensor board is way too expensive – investigating
alternatives
 Fashion designer dropped out (new day job) – in discussions
with others
 A lot of “real life” happened this year

4.  Kickstarter page is ready to launch, complete
with promo video
 Prototype PCBs are complete and tested
 It will happen!

6.  Learning exercise for designing PCBs!
 Started with Eagle and
switched to Fritzing
(www.fritzing.org)
 Prototypes manufactured at
OSH Park (www.oshpark.org)

7.  User Port device
 Hayes emulation or menu-driven
 All RS-232 lines (RTS, DCD, DTR, RI, etc) connected to User Port
 802.11 b/gWi-Fi
 OnboardTCP/IP stack includes DHCP, UDP, DNS, ARP, ICMP,
HTTP client, FTP client andTCP
 SecureWi-Fi authentication viaWEP, WPA-PSK (TKIP), and
WPA2-PSK (AES)
 UP9600 hack supported
 Onboard MicroView (Arduino Uno with OLED) - Programmable
 64 x 48 OLED display
 Reset Buttons for C64/MicroView/Wifly

9.  Default: As per block diagram
 Standalone: Power jack provided for +3.7V to +16V to use the
MicroView and RN-XV on their own
 Interfacing: Remove RN-XV Wifly and use MicroView’s GPIO
to interface C64 to outside world (analog input, PWM output,
digital I/O and I²C) – all pins broken out along top of board

10.  Six prototype boards manufactured – currently onVersion 2
 Software in very alpha state, but functionality proven
 Code and documentation on GitHub
(https://github.com/LeifBloomquist/WiFiCart)
 Outstanding issue with buffer overruns (next slide)
 Yes, I plan to sell these! Price ~$160 USD + shipping
 Recommend MicroView programmer for $20 more

12. ?

14.  Tiny PCB that interfaces Arduino Nano to C64 Control Port
 Emulates Joystick, Paddles (X/Y), 1351 Mouse (soon!)
 Yes Glenn, you can use it with GEOS
 All Arduino Pins are broken out for interfacing sensors
 USB (Mini-B) interface to PC –Virtual Serial Port
 I am planning to sell these too!
$10 for the PCB, $20 populated, $50 with Nano
