Versatile ATtiny Programming Adapter

Lucky Resistor designed this programming adapter for ATtiny13 and similar chips:

A Versatile ATtiny Programming Adapter

As mentioned in my article about designing a cheap plant watering sensor, I built a small adapter which can be used to pre-program the ATtiny13A. This is necessary, because once soldered on the board, I only have a debugWire interface, which has to be enabled first.

The adapter has a small 50mil JTAG header, where the Atmel ICE can be connected with the board. There is also room for a USB mini jack, which is used to power the MCU while programming. A small on-off switch is used to power the MCU and a LED is placed as indicator to see if the MCU has power.

One of the DIL/ZIF adapters is mounted on top of the female headers. Most of the adapters for SO-8, SO-14 and SO-16 will work with this board.

To make the board more versatile, I added a number of jumpers and solder points. By default, the adapter is connecting to the right pins for the ATtiny13A, but you can cut these routes and solder wires onto the board to implement any kind of connection you like.

The design files are available on GitHub:

LuckyResistor has shared the board on OSH Park:

ESP8266 Pogo Jig Programming Board

We like the novel orientation of pogo pins that Wing Tang Wong used in this board design:

This is a board designed to take a WeMos D1 Mini board(with the ESP module removed) and use it as a USB interface with built-in reset/flash functionality for bare ESP8266 modules similar to the ESP-12 units.

Portable Heartbeat Logger

9955741479756953245

Ole Andreas Utstumo designed this board to log ECG waveforms:

Heartbeat Logger

A portable device that will log your ECG – the “waveform” of your heart – to your phone via bluetooth or to a memory card

6636431453032406605

The Heartbeat Logger is a portable device that that logs your ECG throughout the day and throughout the night, 24/7. While this certainly is nothing new, even as an open source project (see MobilECG), Heartbeat is a project that, aside being of personal value for me, is designed to be simple to use and understand, and might serve a purpose somewhere for someone.


The firmware and hardware design is available on GitHub:

Ladder board for simple Automation

chmod775 designed this compact, standalone board to be programmed with a simple visual language:270681483106954815.jpg

Focus

Focus born with the purpose of making a prototype board that simplify every aspect of programming.

Spent the last hour writing down the main concept of the Visual Programming Language for the Focus!  It’s just a simple sketch, but I wanted to share it with you the main reason why I’m building it.

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:

Vertically mountable Arduino – PCB only

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

OnChip Open-V Arduino Compatibility

OnChip has posted a Crowd Supply update on their plans for Arduino compatibility:

Open-V Arduino Compatibility

Arduino compatibility can mean a lot of things to a lot of different people, so we’ll try to be as concrete and specific as possible. For the Open-V, Arduino development tools, and interoperating on a hardware level with existing Arduino shields.

We’ve updated our live, web-streamed demos to include an Arduino mode in addition to the assembler and C modes we already have. You might also notice the relatively new Blockly modes and a refined layout of the demo page. Go write some code and see the results live streamed!

$3 Tinusaur board on IndieGoGo

Neven Boyanov has launched a new Tinusaur campaign on IndieGoGo:

Learn, Teach and Make with the Tinusaur

Small microcontroller board that could run Arduino and help you learn, teach others and make things

uvloj5csuhcx0ri4yn5c

The Tinusaur is powered by the Atmel ATtiny85 microcontroller.

We want to bring the cost down to $3 for the basic “lite” boards
and allow more people to be able to get them.
