Several years back we made a large fortune teller. We wanted to mimic an arcade cabinet. Instructions are displayed on the LCD screen and the fortune is printed out on the thermal printer. We had a lot of fun building this.
We currently have a moisture issue in our basement and are looking for a DIY fix.
Our solution is to use an Arduino DHT22 Humidity Sensor and a fan. This sensor cost about $9.50, which is one of the cheaper humidity sensors out there. For right now we are just prototyping a small desktop version so we bought a tiny fan for about $3 as well.
A new book buy Andrew “bunnie” Huang has just arrived called The Hardware Hacker: Adventures in Making and Breaking Hardware. This looks to be great read. Bunnie is the maker of such products as the much loved Chumby (we had one), the opens source computer Novena and others.
“Huang’s journey starts with his first visit to the staggering electronics markets in Shenzhen, with booths overflowing with capacitors, memory chips, voltmeters, and possibility. “
Sometimes you need to go away from home and can’t get a relative or neighbor to feed your pet. Well, this is where DIY pet feeders come in. A littler tinkering, some soldering, some code and presto, a pet feeder. See the four different versions below.
DIY guitar effects pedals combine the electronics and music worlds. Here we are barely scratching the surface of this fun hobby.
Basically for building a pedal you have 3 main options. You can modify an existing guitar pedal, buy a kit or make one on your own based on schematics.
It is fairly easy to monitor moisture levels of your indoor plant soil using a microcontroller like an Arduino Uno.
It is a little more work to do this for outdoor plants because you probably need a weatherproof housing. Some more complicated projects even go on to turn on your outdoor water for you.
Less than two weeks away, it is time to make your special someone a present. Below are five DIY projects that involve gluing, soldering, microcontrollers, painting and general making to create gifts for Valentine’s Day.
Fans of the Harry Potter movies will remember the Weasley family clock that tells where everyone is. For more about the clock see the Harry Potter Wiki.
Of course something like this makes for a great project. We have rounded up four versions of it below and what they use to make them work.
