Check out the POV clock which was sent in by [Taciuc]. The board is spun by a stepper motor which takes a little while to stabilize. But there is an easter egg in the code itself. This is the same chip for which we just saw an Arduino act as the programmer.

In addition to the chip you need a crystal oscillator, a couple of 3. There are a couple of LEDs in the design, but we assume these are for feedback and are not crucial to the functionality of the circuit.

Just looking at this little thing makes our hands ache. But [Kirren] did do a great job of building an N64 controller inside a tiny project box. You can just make out the analog stick to the left, but that silver ring on the right is actually a 4-direction tactile switch which stands in for the C buttons.

Looks are deceiving, because if you get him started, this duck says some vulgar things. Boy was he right. The stock toy can already sing a tune while flapping its beak and wings. The best part is that this is going to end up in the hands of someone else thanks to a Secret Santa exchange. The build article linked above is safe for you to read at work, but the video embedded after the break most certainly is not.

This project is a bit older and a bit dirtier. The most important is a PIC 16F which handles both the counting and the serial communications. Since this microcontroller is not a dedicated counter chip a little bit of trimming must be done to bring the accuracy into spec.

In order to get everything to fit into the small enclosure the circuit was free-formed without a PCB or protoboard and the case of the DIP chip had to be ground down just a bit. As for the readout, a simple script can grab the data and display it in a terminal.

This collection of model vehicle hacks adds obstacle avoidance in an attempt to make them autonomous. But there are full schematics, board layout pictures, and the code for both this vehicle and a second Tank version.

The 16F an older device but is still a very capable little device 18pin - the same number as the venerable 16F Importantly it has its own internal clock running at a rate of 4MHz. The 16FA version is still in production as of Apr and is an enhanced version of the 16F mainly its nano Watt power down capability - and it is also capable of operating from 2V or above , whereas the 16F operates from 3V or above in all other respects the 16FA is identical to the 16F - pinout, internal peripherals and mempry architecture.

The PIC 16F628: Why the PIC 16F84 is now obsolete.

Why assembly? It's produces fast and efficient coding over C for basic functions related to electronics control. This enables one to really access the powerful features of the PIC. As a RISC processor it has only 35 instructions to learn. They operate at the register and bit levels.
