10K potentiometers. Toggle switch.
Headers for other connections are optional and wires can be soldered directly to the board.
When soldering is complete, clean board with pure alcohol to remove flux residue.
Board should be powered 9V 1A for 5V fans and 12V 1A for 12V fans.
Set proper laser voltage before connecting laser.

Day 192 - Another geeky delivery today. This time an Arduino Uno microcontroller board.
This has a couple of advantages over the Raspberry Pi that I have been dabbling with as it can handle a 12v power feed and analogue inputs.
Thrilling yeah?!? 😂

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.
A good power supply is an essential subject to the microcontroller's base project; it's like a heart that gives a life to our microcontroller. Sometimes we take it for granted the important of having an adequate power supply to our microcontroller project and this can lead to the unexpected result or behavior from the circuit.

Have you ever thought that most of our perception about the robot is based on the Hollywood movie! The well-known 3CPO and R2D2 from Star Wars until the little cute garbage compacting robot named WALL-E; all of these machines are example of our dreams or should I say our quest to what we all think about the robot should be. Although the robot that we are going to build here is still far away from the technologies shown on those movies but at least it will give you an introductory to the robotics world. for more information please visit www.ermicro.com/blog/?p=983
This is a full size mockup I put together to test some concepts for my LED array project. There are 16 RGB LEDs spaced about 2.25 inches apart, with scored and folded cardboard light separators. The final array will have 24 of these rows, with the same minimal spacing between all pixels (no 3/4 inch border). The LEDs are PWM controlled to any of 4096 brightness levels per color.
Microchip Technology's PIC18F87K90 8-bit microcontrollers (MCUs) feature nanoWatt XLP Technology, 1.8 - 5.5V Operation and CTMU Module for Capacitive Touch Sensing. The MCUs can also drive LCDs up to 192 Pixels.
This is the CC2530, an 8051 microcontroller with integrated 2.4GHz radio from Texas Instruments. As usual, this had to be rather cruelly compressed to fit on Flickr, even with a Pro account. Email me if you'd find the original to be handy.

My Arduino, on a bamboo base-plate, connected to an Allegro A3982 stepper motor driver chip. The chip is surface-mounted on the other side of the PCB.
The 8 pins PIC12F683 microcontroller is one of the smallest members of the Microchip 8-bit microcontroller families but equipped with powerful peripherals such as ADC and PWM capabilities. This make this tiny microcontroller is suitable for controlling the DC motor speed. In order to demonstrate the PIC12F683 capabilities and to make this tutorial more attractive, I decided to use the PIC12F683 microcontroller to generate simple and yet fascinating laser light show from a cheap keychain laser pointer.

This is the replacement hardware. The core is a PIC18f4550 controlling everything with a 20Mhz oscillator to supply the PLL for the 48Mhz required to run USB should i ever get round to implementing that. The CPU runs at 8Mhz from the internal osc. There is a MAX232 to drive the serial port and some transistors to switch relays for the spindle and that is about it. the 9 pin plug floating there is just to allow me to debug the board when it is not in the machine. The screw terminals will be for the motor and the spindle encoder but the encoder is not implemented in code yet so I haven't connected it. Some fly back diodes for the relays, caps for the MAX232 charge pumps, transistor base resistors, LEDs for debugging, ICSP plug and some wire make up what is left. Not really all that much there. I will probably add another transistor and 2 resistors and a cap to this to amplify the PWM signal since the PIC gives out 5Vpk-pk and the PWM in the control box needs 0-10V in. (I know its a bit silly generating an analogue voltage from a PWM output only to use it to control another PWM drive but this way it is a direct board swap.)
