Seeed Fusion Gallery Top Ten Projects – April 2018

It’s a bit late, but here is the 2nd Seeed Fusion Gallery Top Ten Projects for the month of April! Every month, we’ll draw up a chart of the most popular projects shared on the Seeed Fusion Gallery that featured on the Seeed Studios Facebook and Twitter channels. Only the most interesting, useful, controversial or trendy projects make the cut. The top three sharers have a $50USD coupon waiting for them in their inbox and the next two runner-ups get $20USD!

April featured many interesting projects with some deep-rooted history and communal support – it was difficult to narrow them down to just a select few. The top ten this month has a distinct Arduino feel as you’ll see from the winner this month, and also a noticeable love for black PCBs.

Projects shared on the Seeed Fusion Gallery are open source and free for anyone to download, modify or order straight from the Gallery. Click on the links for the Gerber files and more information!


YAZ180 – Modern Z80 Single Board Computer

shared by Phillip

At number one we have another nostalgic entry in the with Philip’s YAZ180 (v1).

A true fusion between the modern and traditional eras, this project combines the Z180, based on the pioneering Zilog 8 bit microprocessor of 40 years ago, the Z80 and the scientific calculator on a chip, the AM9511A, with modern interfaces and features.

The wealth of interfaces including I2C, WiFi and USB keep the chip of 4 decades ago relevant today.

Aside from the spectacular concept and design, this project is by far the most well documented seen so far in the series. Phillip’s (or Felipu’s) blog includes every little detail and observation made during for the development of these boards from idea development to debugging. It is fascinating to see the thought processes that culminate into the final project, while at the same time, being able to sit a lesson in hardware history and design.

If that wasn’t enough, Philip went on to produce version 2 with equal attention to detail and thoroughness.

Very nice job Phillip

Arduino Mini Pro and NRF24L01

shared by Milosh CZ

Makers tend to have a have a soft spot when it comes to Arduino. For many hobbyists, myself included, it was the real hands-on primer to the interaction of hardware and software. Perhaps this contributed to the popularity of Milosh’s project and other Arduino based projects in the top ten.

This board combines the smaller Arduino Mini Pro with the popular RF module NRF24L01 by Nordic Semiconductor, and equips the board with a dual AA battery case. Operating from 0.9V, the power supply provides a sleep current of 3.4V under 1uA.

USB Volume Controller

shared by Hylke33

This rather unusual gimmick at third place is simple yet unique. DJs and music lovers in general will welcome the rotary action of this USB volume controller. Based on the ATMEGA 32u4 microcontroller, it also has three LEDs for you to play with. Just plug it into a spare USB slot, upload the Arduino sketch and you’re good to go.

Then you can add your own 3D printed or CNC milled case and knob to complete the effect.

It’s a lovely idea, but personally, I think I’ll stick to the volume buttons.

Runner Ups – Not in the top three but honorable mentions nonetheless. 4th and 5th place get a $20USD coupon!

 2×2 MIMO FMCW Radar RF Shield

shared by Tgrosch

This Arduino shield board is a 2×2 MIMO continuous wave, frequency modulated radar.

This radar Arduino shield was designed at Kennesaw State University and based on the MIT coffee-can design. There is a microwave VDC, power splitter, mixer, three amplifiers, and two SPDT antenna switches. The shield board is designed for the host microcontroller to control the switches through GPIO outputs, utilize a GPIO output to modulate and an analog input to digitize the IF.

Powarduino is a simple “all in one” Arduino based project board, with 6 high power PWM/digital (voltage independent) outputs, 6 analog inputs, 6 buffered digital outputs and an I2C bus.

I was looking for a simple experimentation board for Arduino newcomers, able to run without any “breadboard” and ready to use. I also was looking for a small and functional SMD soldering practice board with big thru components, and smaller SMDs (0804 or 0603 are the smallest devices).

Karabas-128 rev.B1

shared by Andy Karpov

ZX Spectrum 128k replica with real Z80 CPU and almost all logic in CPLD Altera EPM7128STC100. PCB designed to fit into original ZX Spectrum 48k (rubber keys) case.

The idea is to make a cheap ZX Spectrum 128k clone with minimum components. Some parts of this schematics are grabbed from the Superfo’s Harlequin 48k rev.G project (like AC/DC unit, tape in comparator, PAL coder). The heart of this project is real Z80 CPU and ULA implementation on Altera CPLD EPM7128STC100. CPLD design based on successor project Speccy2007 by syd.

This is the first prototype PCB, it just works, it’s fully tested, except ZX BUS. Possibly bugs/errors there, need more external devices to test 🙂

– Another Z80 gem!


MarkDuino 1.0

Fully functional, small and cheap Arduino based board with extra features.

MarkDuino is a small (just 58x33mm) and cheap Arduino clone board which is stripped out from unneeded components with some extra features. It has a built-in I2C connection which is handy if you want to add LCD display with I2C 1602 LCD Controller out-of-the-box. This board doesn’t have a voltage regulator so you must provide 5v power (externally) or power it via USB using USB to TTL Converter UART module.

– Just goes to show anyone can design their own personal Arduino!

Allwinner V3s Dev-board

shared by Marcel

This is a development board for the Allwinner V3s. The Dev board is aimed for industrial usage.

Scrumtato is an ATtiny85-based gadget to keep overly passionate developers from excessively talking during daily stand-up meetings. The name stems from the combination of SCRUM and Hot Potato.

During our daily stand-up meetings (SCRUM), as we are a team full of talented and passionate developers, we just love to talk too much. This stretches our meeting and keeps us from getting the most out of our working hours. To solve this problem, here comes Scrumtato: A gadget to make daily stand-ups agile again!


Maarten Baerts Pagoda FPV Antenna – Part 1 [RHCP]

This is Part 1 for building a set of 16 Pagoda Antennas.You also need Part 2 and 3. There you have to choose for RHCP and LHCP.

How can you share your designs on the Seeed Fusion Gallery? Simple, every time you successfully place an order on Seeed Fusion, you will have the option to upload production and design files, add pictures and write a little something about your project. Anyone can then download the files or place the exact same order with the click of a button. Also, every day, we will pick some interesting projects and share them with our friends on Facebook and Twitter. Oh, and did we mention that you’ll get a $5 coupon just for sharing? Give it a try it.

To see more designs and see what Seeed Studios is getting up to, be sure to follow us on Facebook and Twitter or visit the Seeed Fusion Gallery directly.

Thank you all for sharing!

  1. I like the volume controller project. But the design files archive seems to be missing the required arduino sketch. Can you help?
