Although you can buy analog tide clocks that have a single hand indicating whether the tide is high or low or somewhere in between, what I wanted was something that would tell me at what time low tide will be. I wanted something I could glance at quickly without having to turn it on, or push …
Today we are going to make a real time clock Arduino shield. Doing so will give you a simple way of adding … real time capability to your projects such as time, date, alarms and so on. We will use the inexpensive Maxim DS1307 real-time clock IC. First of all, we need create our circuit …
There are quite a few geiger counter instructables. The difference with this one is that I wanted to give it a modern interface, similar to smart phone touch screens, that anyone would feel comfortable using. The reason for this is that I want to use it as an educational tool to teach kids (and interested adults!) about …

Components In addition to an electronic breadboard, wire links, a 9V battery and a battery clip, you will need: QTY PART DESIGNATOR NOTES TYPE 2 22k resistors (red – red – orange) R2, R3 …
Introduction I’ve been fascinated with joule thief circuits since I made my first one. It’s amazing what all you can power from a single AA or AAA battery. The only problem is you can’t do much beyond light up an LED because the current isn’t “always on”. With a couple of extra components, you can …
