Surface Mount Technology (SMT) Workshop

In the course of attending a lot of fairs and exhibitions, we’ve noticed that our cameras and components attract the attention of people from all walks of life. We’ve found that despite our reassurances, people discovering the world of Open Hardware tend to doubt their capabilities where soldering tiny components by hand is concerned.


This is why we hold Surface Mount Technology workshops – so that with a little confidence, the right tools and some initial guidance from members of our team, anyone can have great fun learning to make their own PCBs. The workshops are very popular and we have visitors designing pendants and earrings with colour LEDs and blinking patterns – which always creates a buzzing atmosphere.

An “Unfortunate” SMD Project

If you like happy, easy to build projects, this is not for you. This is only for people who like to grind their teeth and pull out hair.

Be warned that trying to hand solder a 0201 package may be considered evidence of insanity and get you committed to bad places by your loved ones or arch nemesis.

Hackaday Prize Entry: MakerNet

One of the biggest trends in whatever market ‘Maker’ stuff belongs to is the Legofication of electronics. Building electronics is hard, if you haven’t noticed. Anything that turns transmission lines, current loops, and RF wizardry into something a five-year-old can use has obvious applications to education. For his Hackaday Prize entry, [Jeremy Gilbert] is building…

How To Share Your Project on OSH Park

This shared project has been created as an example of how to link to project resources:

Here’s the steps to share your OSH Park project:

Step 1: Click ‘Start sharing’

Navigate to your Projects page and click the ‘Start sharing‘ link for the project that you wish to share:


Step 2: Edit your shared project content

The shared project content is formatted by Markdown syntax.  This is a good guide:  Markdown Cheatsheet

We recommend you include a link to your projects primary documentation such as Github, Hackaday.io, Hackster.io, or Tindie.  Remember to publish your BOM as well, since your project cannot be built without it.

Here is what the shared project edit page looks like:


Step 3: View the Shared Projects directory

Navigate to the Shared Projects directory page and you should see your new shared project at the top.  You can also search for shared projects from this page.

Hackaday: Ohm? Don’t Forget Kirchhoff!

It is hard to get very far into electronics without knowing Ohm’s law. Named after [Georg Ohm] it describes current and voltage relationships in linear circuits. However, there are two laws that are even more basic that don’t get nearly the respect that Ohm’s law gets. Those are Kirchhoff’s laws. In simple terms, Kirchhoff’s laws…

Open Panzer Sound Card


Open Panzer Sound Card

The Open Panzer Sound Card is a work in progress with the goal of bringing inexpensive, high quality, and open source sound functionality to RC models but especially to tanks using the Tank Control Board (TCB).

The board is actually made up of two components. First, an off-the-shelf PJRC Teensy 3.2 is used as the onboard processor. The Teensy is then plugged into a socket on our custom carrier board that adds a Micro SD card slot (max 32 GB), an additional 16 MB of flash memory, an LM48310 2.6 watt audio amplifier, and headers for external connections.

Patrick Van Oosterwijck created this board to power the Raspberry Pi with a LiFePO4  battery:



Many IoT and other projects are based on the Raspberry Pi, but usually little thought is given to the power supply. Most project use generic cell phone adapters or USB power banks, which is fine for one-off projects where the duct taped parts and cabling don’t matter and it’s expected that SD cards will die because power was removed with the Pi running.


But when you need reliable non-stop operation for your prototypes, or you’re ready to turn your project into a good looking product, or you want to use different power sources such as solar, it’s time to look for a serious power manager for your Pi.


Built on the solid foundation of the #LiFePO4wered/Pi, this project provides Pi bootup and shutdown management based on button or touch, input voltage, battery voltage and time, all while making sure the Pi always performs a clean shutdown before power is removed.
