Many PIC microcontrollers have built in touch pad capability. The PIC 16F1937 for example has 16 inputs for the capacitance module. These allow for a simple and inexpensive way to add buttons to your project without adding physical switches. Nice thing about these switches is that they will not fail after a certain number of uses like a physical switch will. Our friend Giorgos Lazaridis from PCB Heaven has designed
With electronic parts getting less and less hobby friendly there will come a time when you can’t get a part in a through hole DIP format. Our friend Dave from the EEVBlog has a new 3 axis accelerometer that he is playing with. The issue is that it is a LGA surface mount chip these chips only have pads on the underside which makes it a pain to work with
If you have a show car you need to see these cool turn signals. They use RGB LEDs to produce multiple effects, lots of the color effects could only be used when the car is in a show environment but this is sure to spice up any ride. Via: Electronics Lab “Why you may ask? Â First off why not! Â Second I take my car to cay shows and just like
PaweÅ‚ from Poland made a great portable AVR programmer. This thing is totally custom, you can see the prototype above and then see the tiny completed version in the pictures below. This is such a nice looking design that you might just need to have your very own. Nice thing is that Pawel has provided everything you need to make your own! “Function description: Write – writes data from file
When placing parts into a laser machine the first step is normally to set the height of the work so that the laser dot can focus on the exact spot that the cutting laser will hit. The dot lasers are mounted off to the side at an angle, it would be ideal if the aiming laser could be mounted directly above the work but of course this is where the
Nicholas Skinner shares how he developed his DIY Central Heating and Hot Water Control System with us. “Features: Two channel (heating and hot water) support. Temporary Override (ignore schedule for 30 min – 1 day), both overriding on, but also off. Permanent Override (ignore schedule). Web based interface for changing schedule / override settings. Schedule support for any combination of weekdays. Schedule support for one off custom schedules on specific
RC cars are tons of fun but driving a RC car using your Android Phone would be even better! Antoine Monmarché used an OpenPicus module mounted in the car to get the job done. There is documentation and source code available here. “The RC car (battery powered) is completely controlled by Flyport. The module manages Wi-Fi link to an Android Smartphone and it drives the servo motors (PWM signal). On
