Picaxe microcontroller project: thermostat. Bottom view with SOIC Picaxe 18X, programming jack to the left of it, and various 0612 size resistors, two for the programming circuit, one a pull up resistor for the temp sensor, one to the reset pin on the 18X, another current limiting for the LED.
Enables serial communication with arduino or other microcontroller for control of external devices (like servos used as projector shutters) or sensor input to control elements in VPT
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.

This is an laser cut enclosure for mobile arduino prototyping. I will start selling this soon. A bit more testing is needed.

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.

The I2C bus (read as I squared C) is one of the most important embedded system serial bus interface first introduced by Philips in 1980; using just two lines called SCL (serial clock) and SDA (serial data) respectively make the I2C bus is a perfect choice to provide additional I/O capabilities to your microcontroller project without changing your microcontroller type and design in order to increase the I/O port pins.

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.

Just the SMT transistors to add on the back. Hand soldering the TQFP AVR microcontroller was interesting.
PCB through the excellent DorkbotPDX batch PCB service (nice colour)!
Arduino UNO was one of the first ever circuit portraits, way back in 2013. This is a new edition with an extra layer and a bit more finesse.

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 Arduino Duemilanove on a 6mm polycarbonate slab with four non-slip feet. The PCB is supported on M3 threaded spacers, and held down with Allen bolts (which I salvaged from a Video 2000 VCR).
I'm getting a Lily Pad wearable open source arduino microcontroller in the mail soon and i can't wait to get going with it!
Saturday SMD help alden out of a time bind party.
We all hung out and did about 30 boards with 30 smd 603 LED's on the board. Very cool stuff. We made a Chinese electronics sweat shop in an Arlington workshop basement.
If you didnt come you missed out!
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 mTouchâ„¢ capacitive touch-sensing keys and sliders, and high-resolution touch-screen designs. Up to two each of EUSART, I2Câ„¢, 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.

NYRR's NYE race values costumes, so I figured I'd throw a little light on my head. I bought a /relatively/ inexpensive headband and sewed the ends of the strip on the back, along with an Adafruit Gemma and a small alkaline battery box. Tomorrow I need only clip the threads and carefully disassemble the electronics to return it to a normal headband.
Sorry for the techno nerdy picture. The excuse is I purchased some extension rings and wanted to try it on something. This is an ESP32 (32 bit processor) board. We use these devices in some of our projects. The board measures 50mm by 28mm. The image is a focus stack of 10 images done in camera.
