Update of the USBHID SDK
The Software Development Kit for our USB Buttons is a programmer's library for direct control of the buttons from your own software. This SDK provides interfaces for C/C++, C# and VB.Net, for Windows and Linux.

This update adds Linux support.

Update of VisualPlace
Freeware VisualPlace assists in (manual or automated) PCB assembly. Component placement is extracted from files generated from the EDA suite (notably the Gerber files, the centroid file and the bill-of-materials). The application visualizes the component placement and converts the files (with corrections, where applicable) for further automated processing. Due to a plug-in architecture, VisualPlace works with many EDA suites, and more can be added.

This update features a translation in Spanish by Juan de la Torre (user interface and notification messages). A navigation button bar was added for performing manual assembly of a PCB on a tablet or panel PC without keyboard. Plus improvements in Bill-of-Materials editor and fixes.

VisualPlace is a free application.

This page is also available in Dutch and in German.

Update of the minIni library
Open source minIni is a programmer's library to read and write "INI" files in embedded systems. minIni takes little resources, has a deterministic memory footprint and can be configured for various kinds of file I/O libraries.

This update provides two new functions for checking the presennce of sections and keys in an INI file, and has a fix for the presence of invalid characters in INI file.

minIni is an open source project.

Update of: Mini-reel for SMD components
The mini-reel is a reel for SMD components on cut tape. The design follows the standard for reels for the essential dimensions (EIA-481). Its outer diameter is smaller, and its capacity therefore as well: about 1/4th of what a 7" reel can hold.

The design is updated with an optional rim to avoid spontaneous unrolling, and a non-linear scale to make it easier to estimate the number of components left on the reel.

New article: Near-Field Probes for EMC testing
Near-field probes, in combination with a spectrum analyzer, are the tools that you use to trouble-shoot EMC problems (notably radiated emissions). This article first describes how you can make good-quality low-cost probes yourself. Following that, it gives some advice in using the probes.
Update of the minIni library
Open source minIni is a programmer's library to read and write "INI" files in embedded systems. minIni takes little resources, has a deterministic memory footprint and can be configured for various kinds of file I/O libraries.

This update includes an example "glue" file that uses file locking for avoiding concurrent access. The example assumes a Posix file interface. Stylistic and portability issues were also addressed.

minIni is an open source project.

Update of VisualPlace
Freeware VisualPlace assists in (manual or automated) PCB assembly. Component placement is extracted from files generated from the EDA suite (notably the Gerber files, the centroid file and the bill-of-materials). The application visualizes the component placement and converts the files (with corrections, where applicable) for further automated processing. Due to a plug-in architecture, VisualPlace works with many EDA suites, and more can be added.

Gerber X3 is now supported: this Gerber extension adds component placement information to Gerber files (replacing CPL files). Support for CircuitStudio was also added. Other new support is for Zebra label printers, the TWS Quadra DVC pick-&-place machine, and Gerber "job" files. Internally, VisualPlace is converted to use the Unicode character set, allowing better internationalization.

VisualPlace is a free application.

All "Large Dome" buttons are now also available with white dome
The USB dome buttons and wireless dome buttons are now also available with a white dome.

This page is also available in German, in French and in Dutch.

New article: Mini-reel for SMD components
The mini-reel is a reel for SMD components on cut tape. The design follows the standard for reels for the essential dimensions (EIA-481). Its outer diameter is smaller, and its capacity therefore as well: about 1/4th of what a 7" reel can hold.
New article: Mini-tray for SMD components
The mini-tray was designed as an alternative to the standard JEDEC tray for semiconductors. It has the same width as a JEDEC tray, but its length is a third of that of a JEDEC tray. Thus, three mini-trays lined up have the same width/length dimensions as one JEDEC tray (the mini-tray is 0.85 mm thinner than a JEDEC tray).

New product: Battery-free Wireless Button
The “Battery-free Wireless Dome Button” is a palm switch with a large mushroom dome. It has a wireless to a USB receiver (that you insert in your PC), and energy harvesting generator that generates electrical power from the act of pressing the button. The advantage is clear: there is no need to ever worry about recharging or replacing the battery.

This page is also available in German, in French and in Dutch.

New product: USB Input module
The “USB Input module” is a 42×23.5 mm module that allows to capture input from a switch or a sensor, and receive it on a PC or workstation as a keystroke. That is to say, the module operates as a virtual keyboard. The module is configurable with a free utility.

New article: Magnetic PCB holders
This article describes a design for magnetic PCB holders that are quite convenient in both manual assembly and machine assembly of a PCB, and especially so if the PCB has components on both sides. The STL files for 3D-printing of these PCB holders are provided as well.
10 July 2019
New product: USB Pendant Button
A hand-held switch on a USB cable. It can be configured to transmit a key press or a mouse click on pressing. It can even be configured to send one key code on a short press, and a different key code when the button is held down for a second.

This button is available with a red or black button cap.

This page is also available in German, in French and in Dutch.

New article: Debouncing with vertical counters
This is an article on efficiently handling switch bounce in software, for multiple switches concurrently. The article starts by showing the effects of switch bounce and explains the paradigm of vertical counters. Then, it introduces a novel implementation with very low latency.
Update of VisualPlace

Due to a plug-in architecture, VisualPlace works with many EDA suites, and more can be added.

This version includes a rewritten Gerber parser, which now includes Gerber X2 support. Other new features are: the outlines of standard packages can be drawn on top of the PCB image, so that you can visually check whether the package fits on the footprint; components can now be rotated by 45 degrees; a new function for inventory look-up for parts in the bill-of-materials. See the release notes for details.
