Back on Track

Finally was able to sit down and solder for a little bit yesterday.

Completed all connections from the 589 parallel outs to pull down resistors, from the 589 serial out to 'duino, grounds, voltage and control lines from 'duino to 589.

Remaining work:

• control lines from duino to 595 set
• ground from 595 set to duino
• voltage from duino to 595 set
• line from duino to speaker resistor
• ground second set of LEDs to duino
• and probably should expose some convenient pins to attach the speaker wires

Wow.  All of the sudden, the workload looks reasonable and testing is in sight.  I only have 2 months left to finish on schedule.

I am still not very confident in my soldering and hope testing isn't overwhelmingly painful, requiring a bunch of resoldered joints.  I am afraid that a few dart hits will cause some of the joints to fail.

I am really liking the idea of a printed board if there is a v2.

Perf Board Diagrams

The diagram I made last night is very cluttered, so I broke it out into a series of specific diagrams that are easier to follow:

The full rats nest

• 2 x yellow
• 2 x green
• 15 x Resistor
• 1 x 100 Ohm
• 6 x 220 Ohm
• 8 x 10 k-Ohm
• 1 x Arduino
• I am using the Boarduino
• Diagrams depict the Arduino Micro
• 1 x Electonic Dartboard
• 1 x 20 pin Ribbon Connector in 2 rows of 10
• 1 x Small Piezo Speaker

Follower Hoax and Winter Sucks

OK, I think the whole follower thing was a hoax.  Probably someone hired to try to keep bloggers posting or something.  whew!  Things are going to be a lot easier now that nobody is watching again.

I was going to get a lot done over the winter, but winter sucks.  No motivation.  Winter's still trying to linger, but spring is squeezing in enough to matter. So I got a little inspired tonight.

Downloaded the latest version of Fritzing and whipped up an "accurate" perf board diagram:

Well, the "no motivation" thing wasn't entirely true.  I did spend a little time messing with Pygame and OpenGL, 'cause when you are making progress on a project and need to focus on its tasks to make the project a success, it's always a good idea to start more projects.

Sigh.  I'll probably end up posting about the "new" game projects.

Me out.
