Fresh hacks every day
[Giacomo] finds that every once in awhile, he needs to flash a sketch to an Arduino while on the go. While he doesn’t always carry his laptop with him, he almost certainly has his Zipit Z2 on hand. He prefers to use the Zipit because it's tiny, it uses Debian, has built-in WiFi, and can run for about 5 hours before requiring a recharge. The only shortcoming is that the device lacks a serial … [Read more...]
[Arto] recently upgraded his home Internet subscription from an ADSL to VDSL, and with that change received a shiny new ZTE ZXDSL 931WII modem/wireless router. Once he had it installed, he started to go about his normal routine of changing the administrator password, setting up port forwarding, and configuring the wireless security settings...or at least he tried to. It seems that he was … [Read more...]
[Autuin] found a Compaq Portable III destined for the scrap bin at Free Geek Vancouver. Upon seeing it he realized that it could still fight; fight against the tyranny of hipsters and their shiny Macbook Pros at his local coffee shop. Unfortunately, being a 286, the computer couldn't do much. He could take the usual route; which is to remove all the internals, and use the vast amount of space … [Read more...]
When [Bill Porter] works on a project, he says that he typically writes his own NMEA standard communications protocols to fit the job at hand. While it makes things easy to troubleshoot, he admits that his custom protocols are wasteful of both processor time and bandwidth. Binary communications on the other hand are more efficient, but a bit trickier to manage. To make things easy for the … [Read more...]
Following Maker Faire, we’ve had a few days to poke around with Digilent's 32-bit Arduino-compatible chipKIT boards and compiler. We have some initial performance figures to report, along with impressions of the hardware and software. … [Read more...]
[Wayne] wrote in to share an item he just finished working on, an I2C GPS shield for the Arduino. While other GPS solutions have existed for quite some time, his caught our eye due to its feature list. The shield removes a good bit of the hassle associated with parsing raw NMEA data from traditional GPS addons. While you have the option to communicate with the GPS module over serial in order to … [Read more...]
[Paul] wrote in to tell us about some interesting Arduino latency issues he helped nail down and fix on the Arduino. It seems that [Michu] was having some problems with controlling his Rainbowduino project we featured earlier this year, and he couldn’t quite figure out why he was experiencing such huge delays when sending and receiving data. Searching online for answers turned up very … [Read more...]
