3D Printed Microcontroller Dice Roller

Posted on: 24 Jun 2016

This is a just-for-fun project I did in the Digilent MakerSpace. Usually whenever I play board games I use a dice-rolling smartphone app since dice are so easy to lose. I thought I would try making my own hardware version though. It turned out really well and was a lot of fun. In this Instructable […]


8T49NS010 Clock Synthesizer and Fanout Buffer/Divider

Posted on: 24 Jun 2016

This reference design features the 8T49NS010 integrated circuit that functions as a clock synthesizer with a built-in fanout buffer and divider. By using an external clock source or a crystal, the 8T49NS010 can generate high performance timing geared towards the communications and datacom markets, especially for applications demanding extremely low phase noise jitter, such as […]


BLE Smart Car DIY Guide

Posted on: 24 Jun 2016

This BLE smart car is completed based on our latest design bluetooth 4.0 chiped- BLEDuino, L298 Motor shield, smart car body. The smart car production is simple, as DIY enthusiasts can complete their own smart car only in the form of building blocks, and the operation is also very simple, just controlling it via bluetooth […]

Microcontroller’s based Password Locker

Posted on: 23 Jun 2016

Hello Everybody , the goal of this instructables is to learn how to do a simple locker for your room, or anything which need to be safe. I’ve made it on a non-soldering card but there is the PCB if you want to make it ! Here is the list of differents components that we […]


xy-ray x-ray scanner

Posted on: 23 Jun 2016

Problem: with my previous work I can take a PCB x-ray at fairly high resolution (see bond wires like above) but the field of view is pretty small.  The above x-ray doesn’t even cover an entire PDIP-40.  How can I see the entire PCB?Linear stageLinear stages are great for this sort of project.  As I’m […]


Theory, Design and Characterization of Delta-Sigma Analog to Digital Converters

Posted on: 23 Jun 2016

In this episode Shahriar explores the world of Delta-Sigma modulators with emphasis on a Delta-Sigma Analog to Digital Converter (ADC). The basic concepts of analog to digital conversion is presented, particularly with respect to quantization noise spectral shape and power density. Next, oversampling ADCs are presented to demonstrate the possibility of increasing SQNR (ENOB) through […]


Picaxe Projects #1: Making Fast Printed Circuit Modules

Posted on: 22 Jun 2016

Experimental circuit board modules can be made quickly and fairly easily. They have the advantage of being more than twice as fast to build than a custom circuit board. They are also easy to test in a breadboard. The modules detailed here are ones I have made using various Picaxe microcontrollers. Step 1: Picaxe Project […]


PicoBuck – RGB LED Driver

Posted on: 22 Jun 2016

The PicoBuck is a small and inexpensive 3-channel LED driver. It employs constant-current buck driving which approaches an efficiency of 95% (theoretical). It’s based on AL8805 LED Lighting Buck Driver from Diodes Inc. Description The PicoBuck supports a wide range of input voltages (6v to 20v) which may be connected to the VIN header. It […]


Simple and small temperature fan controll

Posted on: 22 Jun 2016

Some notes: 1. The C3 can be omitted, its purpose was to filter noises picked up by connecting cable between board and sensing transistor, but as the transistor is mounted on the board it become unnecessary. 2. R8 is optional and is for reducing the fan speed. Its value must be calculated according the fan […]
