Fresh hacks every day
If you’ve ever wanted to dive in and take a look at how memory hardware is implemented here is a good example of how to implement some latching circuits with ether BJT or CMOS transistors. BJTs require biasing resistors which increases the complexity and power consumption when compared to CMOS. If power consumption isn’t an issue you could certainly make … Read the rest
[Rhys Goodwin] has been working on a system to print resist onto copper clad using an inkjet printer. This is a toner transfer alternative as it still uses toner, just not quite as you’d expect. The first step is to modify an inkjet printer, separating the carriage from the feed rollers in order to increase the clearance for the substrate. … Read the rest
When [Dave] installed hardwood flooring in his house, he needed a solution to help automate the monotonous task of routine sweeping. Rather than go out and buy one of the many existing automated sweep robots out there, he decided to use his passion for LEGO Robotics to design and build a NXT based Swifferbot he calls Pulito. His version implements … Read the rest
It seems that we have caught Design Contest Fever here at Hackaday. After covering some other design contests, and asking readers to send in more, we heard from a couple tippers about Renesas’ challenge. Like many of the other contests, entrants can submit their ideas, and possibly receive a free development board to get them started. Unlike the … Read the rest
