Fresh hacks every day
Cheap things come to those who wait. If you’ve had your eye on a TI Experimenters Board (MSP-EXP430FR5739) now’s the time to pull the trigger. You can use the coupon code MSP430_FRAM to get 50% off. This pulls the total price down to $14.50 plus shipping with several readers reporting free shipping.
The board features an upgraded MSP430. Instead … Read the rest
For his first project using the TI Launchpad [VOJT4] built a lap timer and counter for slot cars. For us it’s always hardest to come up with the idea of what to build and we think he found a great one here.
Each time a car passes the finish line of the track it trips a reed switch that … Read the rest
[Giorgos Lazaridis'] most recent project was to build a capacitive touch pad. Since he’s using a PIC 16F1937 it will be relatively easy. That’s because it has a 16 channel capacitance sensing module built right in. But there are still some design considerations that make the development a bit touching.
This isn’t the first time he’s worked with capacitance … Read the rest
The sun is a great source of energy, however, efficiently collecting this energy can be hard to do. One thing that can improve the results of solar use is to actually track the sun’s movement. [fanman1981] hooked up his own homebrew solar tracker using some pretty clever techniques.
For this hack he used two Harbor freight 45 Watt solar kits… Read the rest
Although [Jack] just graduated High School and doesn’t have much experience with electronics, that didn’t stop him from building the DUO Adept, a homebrew computer built entirely out of TTL logic chips.
The DUO Adept has 64k of memory, 6K of which is dedicated to the video ram that outputs a 240×208 black and white image onto a TV. Bootstrapping … Read the rest
