  • They told me to beat this game I had to develop hair-trigger reflexes.

  • Artsy demos and consumer-friendly soundtrack. Looks like Fridays now cater to the lowest common denominator as oppose to the geek/tinkerer. We're a few episodes away from an typical Apple commercial. I miss Rob.

  • I work with industrial grade lidars and I say $90 is pretty reasonable for these specs. Scanners I get to use are $5-50K each. If you want a faster refresh rate but shorter range, look into taking apart a robotic vacuum cleaner. There are many of them in second hand stores. When the battery dies people don't bother replacing it. You can have find a good lidar with a turntable or a prism built in for $10, and SPI data output.

    50Hz rate is painfully slow though. I had an infrared scanner with such refresh rate, doing pixel by pixel mapping of a rectangular area. For a 800x600 output image it would take 2.7 hours in an ideal world, but if you add few milliseconds to command steppers, a little sync mismatch between the sensor and the microcontroller, you end up with actual run of about 4 hours. And you better hope your scene remains perfectly still all that time, and your battery packs don't run out. All for a less than half-HD depth image.

  • BlueSMiRF Mega proudly receives his RoHS certification badge.

  • Yes, why stop there. If 2GB is unlimited, then I guess $79.95 practically "free" and 6 months is almost an eternity. "Free unlimited forever everything plan". With no terms or conditions they can claim pretty much anything they want.

  • An 8-core 32-bit Propeller Chip (https://www.sparkfun.com/products/12637) can perform several functions in parallel. According to Pete, propelling an aircraft isn't on of them.

  • Peer-to-peer mesh networks are a pipe dream for now, but if the FCC keeps messing with the internet, maybe it'll generate enough demand for an alternative.

    I've set up small line of site WAN's in the past using microwaves, light and radio. Technology available today can be used to form a new continental backbone for a different type of net. Security and speed would be an issue, but who says it'd be used for everything. It could start off in parallel to the conventional internet and improve over time.

    Some phones are already able to run in "walkie-talkie" mode when the carrier is unavailable. If wi-fi routers did that, we'd be set.

  • What is going to happen to the Autonomous Vehicle Challenge? Does the new facility have space to accommodate it?

  • I knew these things would come in handy one day! I've been slowly chopping up my infinite supply for wire in robotics projects. Now if only I could find use for hundreds of IDE drives sitting next to the crate of cables.

  • I hope no one got fired over this. If a SparkFun employee is behind this and not an outside vendor, please go easy on him.

No public wish lists :(
