Various modes of Marcy 2's fully functioning wifi camera are shown. A 168Mhz 128k RAM chip compresses JPEG & streams on 802.11g. As the frame size increases & color is enabled, the framerate goes down. Body movement around the antenna makes it drop packets. It still compresses a lot faster on 168Mhz & 128k RAM than a 166Mhz Cyrix with 64MB SDRAM did, 15 years ago. The Cyrix only did 5fps 320x240 color, if you were lucky.
With a new, unmelted camera finally arriving, the true frame rates & bit rates could be known.
640x480 color: 3fps 800 kbit
640x480 grey: 4fps 1 megabit
320x240 color: 20fps 2.5 megabit
320x240 grey: 30fps 3 megabit
Quite an improvement over the UART cams from Sparkfun. The bitrate got a lot higher when the lens wasn't melted. All the 640x480 modes had to go to single buffers to fit in the RAM. They could double buffer if the quality was reduced way down. Noise is now the real problem. Capacitance directly on the wireless dongle is the key. Networking bitrate is way up. Bluetooth wouldn't be an option.

Another $20 in Nate's retirement fund.
Another perfect soldering job.
Marcy 2's eye.
Marcy 2 now needs a huge cash infusion to continue. Hobbyking has stopped restocking most everything that made it not Tower Hobbies, leaving only full priced versions.
