Fresh hacks every day
A few weeks ago, we saw codebender, an online replacement for the Arduino IDE that allowed you to upload a sketch to your board from a web browser. Over on the codebender blog [Vasilis] and his team are rolling out a way to remotely upload code to an Arduino over Ethernet. Now you don’t even need a serial connection … Read the rest
It’s no secret that Ethernet shields for the Arduino are a little expensive. With the official Ethernet shield selling for about $50 and other options not much cheaper, there’s a lot of room for improvement for Arduinofied Ethernet. [Boris] over at Open Electronics has a solution to this problem: his Ethercard powered by a $3 Ethernet controller.
The Ethercard uses … Read the rest
[Alexandre] wanted to set up a web-based temperature logger with his Arduino, but found the Arduino Ethernet shield a little finicky. Since his Raspberry pi was just delivered, he figured he could use the Raspi as an Ethernet shield with just a little bit of coding.
After [Alexandre] set up his Arduino to send a thermocouple through the USB, the … Read the rest
[Andy] loves his Memotech MTX computer. It’s an oldie with a Z80 running at 4MHz; the perfect target for an FPGA port. The ReMemotech has everything the old one has – cassette interface and all – and can run up to six times faster than the original.
If you’re going … Read the rest
[Charles] wrote in to share the project he just built for the London Hackerspace. He calls it CoolBot, and as the name indicates it’s responsible for keeping the laser cutter from overheating.
At its heart the system is a water pump. It uses a plastic storage container as a reservoir, with an outfeed from the laser tube coming in … Read the rest
When [Bobo1on1] upgraded his Internet connection from ADSL to Fiber he ran into an issue of actually getting that speed to his desktop computer though his LAN setup. Before he had been using a telephone extension wire which ran from where the DSL entered the house, through a splitter, to his computer where the modem was located. Now that the … Read the rest
During the gilded age, oil magnates, entrepreneurs, and robber barons would have a ticker tape machine in their study. This machine would print stock and commodity prices and chart these men’s assets climbing higher and higher. A lot has changed in 100 years, as now [Adam] can be kept apprised of what @KimKardashian, @BarackObama and @stephenfry ate for breakfast with… Read the rest
