Quest for a Logic Analzyer

“Since I started this adventure in hardware I have wanted to get an logic analyzer. I have an older but good oscilloscope that only goes so far when it comes to digital logic signals. I could go for the Saleae …

Raspberry Pi Rainbow Ruler

“This project uses a Raspberry Pi, a PmodACL2, an RGB LED, a Digilent PCB Ruler, and LabVIEW MakerHub LINX in order to change the color of the LED depending on the acceleration measured. The front panel is also updated to …

Temperature controlled fan

“Im currently mainly working on my new anemometer design but once in a while I get distracted. For example when my Keysight E3645A lab power supply was making so much noise that I could hardly concentrate. Thats when the idea …

USB Power Meter

“Since USB has become more and more a power delivery standard, it would be nice to have a convenient way to measure the power consumption these devices need. Of course there are already power meters out there, but they are …

Yet Another Arduino Boombox

“This is another version of a music device with an Arduino UNO, a Bluetooth receiver, an FM radio, a clock and a small IR remote, all with a small touch screen, so a combination of several of other Instructables that …

5V to 12V Step Up DC-DC Converter

“Step up DC-DC converter is based on LM2577-ADJ IC, this project provides 12V output using 5V input, maximum output load 800mA. The LM2577 are monolithic integrated circuits that provide all of the power and control functions for step-up …

AC PWM dimmer for Arduino

“Over 3 years ago, I published a simpel TRIAC AC dimmer for the arduino. That proved to be a very popular design. Yet in spite of the simplicity of the circuit the software needed was a bit complicated as it …

Arduino controlled light dimmer

“Switching an AC load with an Arduino is rather simpel: either a mechanical relay or a solid state relay with an optically isolated Triac. (I say Arduino, but if you use an 8051 or PIC16F877A microcontroller, there is stuff for …

LED Night Clock

“I came up with the idea of creating a neopixel clock, where each neopixel shone into some frosted acrylic, red signifies hours, blue minutes and green seconds. The colours are mixed as they overlap creating a bit of art as …

Make the Ultimate Bluetooth Speaker

“I really really Want a Bluetooth Speaker that is decent in form and performance. I want a Bluetooth Speaker to last longer and affordable in price but here in the Philippines good performance is equals to higher price you need …
