Fresh hacks every day
The coffee maker which [Donald Papp] uses every morning has a water reservoir on the back that can last for several days. This means he forgets to check it and from time to time will return to find that nothing has brewed. He decided to add a low-water indicator to the machine. His approach is about as simple as it gets and we admire that accomplishment. If it were our project we'd probably try … [Read more...]
We were skeptical about Keurig machines when we first heard about them. Although we still scoff at the added waste of throwing away a plastic container of used grounds for each cup of coffee made, we tried one at the in-laws and it does brew a great cup of Joe. One of the draws of the machine is that it does it pretty much automatically as long as you fill it with water first. [Joseph Collins] is … [Read more...]
Roasting the perfect coffee bean is an art form. But even the most talented of roasters can use a little feedback on what's going on with their equipment. [Ludzinc] recently helped out a friend of his by building this set of 7-segment displays to show what's happening with this coffee roaster. The yellow modules hiding underneath the display panel are responsible for setting the speed of the … [Read more...]
Blinking lights is a lot of fun, but if you're getting an EE degree the cool stuff becomes a bit more involved. In this case, building your own radar is the thing to do. Here's a coffee can radar setup being shown off by a group of UC Davis students. Regular readers will recognize the concept as one we looked at in December. The project was inspired by the MIT OpenCourseware project. One of the … [Read more...]
Beta fish are one of the easiest pets to care for. So when [Derek] gave his girlfriend one for Valentine's day he thought the job was done. Turns out these tropical pets want 75-80 F water and that's not going to happen in a plain old bowl when you keep your home thermostat in the mid sixties during the winter. While looking for a simple heating solution he stumbled across the idea of using a … [Read more...]
This isn't a thrift-store coffee table modified as a craft project. [Dandujmich] built it from the ground-up using framing lumber, bottle caps, plastic resin, and some electronics for bling. The first step was to see if he had enough caps on hand for the project. It's hard to grasp how many were used just by looking at it, but the gallery description tells us there's about 1700 which went into … [Read more...]
Senseo coffee makers are automated brewers that use coffee pods. [Ronald] had one, but wasn't satisfied with the quality of the coffee it produced. His solution was to hack it apart and build his own automatic coffee machine with the innards. The coffee brewing part of the system is controlled by an ATmega8. This reads the temperature using the NTC sensor from the original machine and actuates … [Read more...]
