From the The Oddbloke Geek Blog, an EEPROM programmer shield designed for Arduino Mega:
Some time ago, I wrote about my DIY EEPROM programmer driven by an Arduino Mega. It’s a very simple, low-tech project … but has attracted a consistently-high number of visitors to the site and is something I use several times a week.
Jeremy Cook writes on the Tindie blog about this IR receiver board by Atomsofttech:
When you think of a “universal remote,” you generally picture an infrared (IR) emitter that can be setup to control your TV, AV receiver, and any other number of devices that work using IR signals. On the other hand, what’s to keep someone from doing the opposite, and having a universal receiver that can be programmed to accept codes from a remote that you just have lying around?
Watch the receiver board in action:
We haven’t tapped yet into the full potential of the Raspberry Pi in terms of ADC. Some have shown that the first gen of Raspberry could go to 10Msps [..] My take is that the new Raspberry Pi’s can surely go above. And I want to try it, either with this old CA3306E or with more recent kick-ass ADCs.

In the open-source world, there are two main choices for PCB design: KiCad and gEDA. But if you’re tired of the boring Hershey fonts telling you which resistor is which, or if you need to comply with ISO 3098, there’s one clear choice: PCB-RND, the improved fork of gEDA’s PCB tool. Why? Because PCB-RND now…
chmod775 on Hackaday.io designed this simple 3D Printed USB Connector compatible with PCBs from OSH Park:
I’ve made this 3D USB Connector because I want to remove the chunky and complex standard metal USB Connector from my new upcoming project.
The design it’s made to be simple and with the height reference from the OSHP ark PCB’s.
From Orlando Hoilett of Calvary Engineering on Hackaday.io:
A sweet Arduino shield with a ton of cool sensors for physiological parameters such as heart rate and breathing rate
The features include:
The design files and source code are available on GitHub:
CalvEngIO/BiomedShieldBlake Ramsdell has posted a new batch of hand-drawn PCB artwork on Hackaday.io:
David I. Herman made some impressive new PCB painting pieces, demonstrating subtleties in shading and Art Nouveau inspiration, precision produced by OSH Park
We are trying to figure out what direction to take this blend of technology and art — should we offer pieces for sale, or offer a service for making your own pieces from your own artwork, for instance. We’re certainly going to continue to explore it from a technology and art creative point of view. If you feel inclined, please take a moment to leave a comment, we are interested in your feedback!
Pidgeon 1 on Crowd Supply is a sub-GHz radio with 500 mW transmission power, RS485 networking interface and a STM32F0 microcontroller:

Hackaday wrote about a nifty hack by Joe Grand:
It’s not too exciting that [Joe Grand] has a toothbrush that plays music inside your head. That’s actually a trick that the manufacturer pulled off. It’s that [Joe] gave his toothbrush an SD card slot for music that doesn’t suck. The victim donor hardware for this project is a toothbrush meant for kids called Tooth Tunes.…
Joe published full documentation for the project on his website:
The PCB is shared on OSH Park:
Joe describes the project in this video:
Hear the toothbrush in action:
We have no idea if the background story is true or not, but we’re not going to let something like “truth” get in the way of a good story. The way [Kwan3217] tells it, first there were hours on sundials. Then when these were divided into sixty minute sections, they were called “minutes”. “Seconds” comes…
