Most of the holes are drilled to 0.8mm, but some are 1.0mm. In particular, the programming header, the I/O port connectors and the reset switch need the larger hole sizes.
Microchip Technology's MCP4706/16/26 non-volatile Digital-to Analog Converters feature buffered 8-,10- and 12-bit voltage output options and integrated EEPROM, and are offered in a miniature 2 mm x 2 mm DFN package, as well as a 6-pin SOT-23 package. The DACs are ideal for applications in the consumer and industrial markets, such as wireless microphones and mp3-player accessories; and applications such as motor control, flow measurement, temperature control and light control.
To give you an idea of the scale of these little blighters, the texture you see them "standing" on is not anything fancy, it's just standard copier paper. I was surprised how much texture you could see on a close up view like this

As the electronics hobbyist one of knowledge that we have to be familiar with is how to make our own printed circuit board (PCB). Making our own simple single side PCB actually is not require a sophisticated technique and technology as you might think, instead most of the required materials is already available at your home.

Microchip's low-cost ENC624J600 standalone, IEEE 802.3™ compliant, 100 Mbps Ethernet interface controllers. These Ethernet controllers combine a 10/100Base-TX physical interface (PHY) and a Media Access Controller (MAC) with a hardware cryptographic security engine, and can connect to any PIC® microcontroller via an industry-standard Serial Peripheral Interface (SPI) or a flexible parallel interface. Additionally, each device has a unique, factory-preprogrammed MAC address and 24 Kbytes of configurable SRAM for packet transmit/receive buffering and data storage. This combination of speed, flexibility and features enables designers to create fast, secure network- and Internet-connected embedded applications with minimized board space, cost and complexity.

Dit een gestripte versie van mijn DIY ArnoSync camera trigger. Deze versie is eveneens opgebouwd rond een PIC 12F675 microcontroller. Het is een versie met een lichtsterkere lens met een brandpunt afstand van 100 mm. Het apparaatje kan hierdoor een object in focus detecteren tot op 1 meter afstand van de camera.
Het is de bedoeling deze versie te gebruiken voor vogelfotografie. De gebruikte lasermodule is een IR (Infra Rood) versie welke ik nog beschikbaar had.
Alle onderdelen passen nog net op een mini breadboardje.
Het geheel is opgebouwd met een minimum aan onderdelen.
De aansluiting naar de Sony A6000 camera remote shutter input gebeurt nu via een robustere 3.5 mm chassis stereoplug. Voor de aansluiting naar de Sony A6000 synchro kabel is dus een extra 3.5mm naar 2.5 mm stereoadapter plugje nodig.
De voeding van het geheel gebeurt door een externe 5 Volt Mini Powerbank van 2600 mAh met schakelaar. Deze combinatie heeft een autonomie van ca. 100 uren. Door het gebruik van de on-off schakelaar enkel wanneer een detectie verwacht wordt kan er meerdere weken op een volgeladen Powerbank gewerkt worden.

This is a striped-down version of my classic DIY ArnoSync camera trigger device.
This version is still build around a PIC 12F675 device. The mini system uses a better lens (100 mm focus) before the SFH309 phototransistor. The working distance to the object is now about 3 feet.
The used Lasermodule is an IR (Infra Red) type which I found in my junk-box.
All the electronics are mounted on a mini prototype breadboard. The connection to the Sony A6000 camera is done via a 3.5 mm stereo chassis plug. A 3.5 mm to 2.5 mm adapter is needed to mate the Sony A6000 external shutter release cable.
The used power supply is a small 2600 mAh Powerbank of 5 Volt with an ON/OFF push button switch. This allows power for more as 100 hours in continuous operation or several weeks when only switched on when an object is expected in the detection zone.
The LPC2119 board is mounted on a solderless breadboard, which is in turn mounted on some thin MDF. The chip is programmed via an RS-232 interface (cable on the left) from a PC running Linux. There's a bootloader on the chip that accepts new firmware according to a simple protocol over the serial link.

Microchip announced a new addition to its PIC12/16LF155X 8-bit microcontroller (MCU) family with the PIC16LF1554 and PIC16LF1559 (PIC16LF1554/9) devices. The PIC16LF1554/9 includes two independent 10-bit 100K samples per second Analog-to-Digital Converters (ADC) with hardware Capacitive Voltage Divider (CVD) support for capacitive-touch sensing. This unique ADC configuration enables more efficient sensor acquisition and assists with advanced touch-sensing techniques for extremely noisy environments, low-power applications, matrix keypads and water-resistant designs.

Microchip Technology's 8-bit, low-cost, Enhanced Mid-range Core PIC16F1516/7/8/9 and PIC16F1526/7 (PIC16F15XX) microcontrollers (MCUs) feature eXtreme Low Power (XLP) technology for sleep currents down to 20 nA, which lowers overall power consumption and extends battery life. An on-chip 10-bit Analog-to-Digital Converter (ADC) with up to 30 channels enables mTouch™ capacitive touch-sensing keys and sliders, and high-resolution touch-screen designs. Up to two each of EUSART, I2C™, and SPI ports enable communication with on-board peripherals. They are ideal for cost-sensitive applications in the consumer (e.g. DVD players, cell phones, MP3 players); automotive (e.g. dashboards, gauges, on-board sensors), home appliance (e.g. washing machines, refrigerators, TV remote controls), and other markets.
First draft of a circuit for connecting a CD-ROM motor to an Arduino so that it acts as a rotary sensor. I want to make it into a spinner control, rather like those which are used to control video playback. Normally, the Hall-effect sensors are connected to the motor driver chip and control the commutation. I've wired them to a comparator chip (TLC3704) and then to the Arduino.
Participants in the first of our two-part microcontroller basics class, presented by Dave O. of CreatorSpace, enjoyed the excitement of circuit building, making lights blink and sensors react by entering and changing only a few simple lines of computer code. Both the kits and the laptops were generously donated by United Space Alliance.

An Atmel ATtiny24 microcontroller drives an R/C servo wich in turn rotates a line LASER taken from a LASER level.
The microcontroller runs a software real time clock and turns the servo and the line LASER to mimic the shadow cast from the style of a sundial as the time goes.

Microchip's PIC32 “MX1” and “MX2” MCUs are the smallest and lowest-cost PIC32 microcontrollers, and are the first PIC32s to feature dedicated audio and capacitive-sensing peripherals. These latest PIC32 MX1 and MX2 MCUs also feature USB On-the-Go (OTG) capabilities, making them ideal for developing audio accessories and other applications in the consumer, industrial, medical and automotive markets.
The idea behind this project is to run a microcontroller and its accessories (LCD's, high speed ADC or DACs, any sort of ANYTHING really) from a single AAA battery. The devices can be tiny and compact, and the MSP430 will last a bazillion years on a single AAA cell anyway. Yes, it does work after only a good 5 hour lab session!
So this is a boost converter that can take anything between 0.7v and 3v and will output a 4.8v signal (for use in 5v logic, LCDs, and backlights) and a 2.5v output for powering the actual microcontroller. It can also output 3v with a resistor change and if I need to I'll add a pot to give a wide range of values.
The board is a lot bigger than it needs to be, but this was more of a proof of concept because I had never built a power converter before. If I was to put this on a PCB I would be able to make it VERY small (smaller than a second AAA cell, wich would validate the effort!)
