Vertically Mounted Arduino-Compatible Board

Clovis Fritzen designed this Arduino-compatible, vertically-mountable board that exclusively uses through-hole components:

arduino-vertical-676x507

Vertically mounted Arduino for Breadboard

I personally love the concept of electronic boards connected in “slots” (vertically attached to a horizontal board), like most industrial-grade PLC’s or even our desktop’s expansion cards (video, sound memory): it saves a lot of space and adds more functions to the system, all at once!

 

The PCB is for sale on Tindie:

tindie-logo2x

Vertically mountable Arduino – PCB only

This is an Arduno-Nano compatible controller that can be vertically mounted to bredboards and boards

Rotary Encoder Breakout Board

UPDATE: Check out the new version with pull-up resistors

I designed this simple breakout board in KiCad to make it easier to put a rotary encoder on a breadboard.   The KiCad symbol and footprint for the SparkFun rotary encoder was created by mcous on GitHub.  I used an updated version with corrected pin numbering.

Here are the rotary encoders that I’ve verified to fit:

BFuse: Electronic Fuse for Breadboard

bfuse02

created this solution to make breadboard prototyping safer for components:

BFuse – Electronic Fuse for Breadboard

adjustable and programmable electronic fuse especially designed for breadboards – a breadboard fuse, or BFuse

bfuse01

The trip current can be set from 50 mA to 1 A but it can measure current up to 6 A [..] It has reverse polarity protection (by P-FET), transient voltage suppressors both on its input and output and two LEDs for indication

bfuse_r1

Set current and actual current can be compared using ATTiny’s built-in comparator or sampled by the ATTiny’s ADC. Then, the microprocessor controls a P-FET switch that opens or closes the power supply
