To install pyserial (Python serial port library), open up a Command Prompt window and use “python -m pip install pyserial” to install it. If this doesn’t work then your environment variables aren’t correct or you need to open up a new Command Prompt window to use the new variables. To test the install, run “python” […]
We have received a number of emails on the performance testing of the TrueRNG. Every one of these have ultimately been attributed to a small sample size or incorrect testing. The TrueRNG products generate true random numbers – there is no guaranty that chi-squared or other statistical tests will fall within any given range for a […]
It’s not the most complex thing, but if you are a synth kinda person then making MIDI devices is essential. This handy breakout board will let you add MIDI to your project in a snap. We’ve got some example Arduino sketches up to test it out. It works with 3.3v or 5v devices. Just hook […]
We’ve decided to go ahead and release some of our designs as open source / open hardware. So we’ve created a github account and we’ll be putting more stuff in when we get time and updating the product page to reflect the license. Right now we’re choosing to use Creative Commons Attribution-ShareAlike 4.0 International (CC […]
We’ve recently updated the TrueRNG downloads page with a signed INF driver for those windows users, and namely Windows 8.x users that are required to have a signed driver. Second one of our users pointed out a bug in Windows 8.1 that popped up an error message in the rngcapture tool. Rngcapture has been updated […]
Some of you have expressed interest in a mdev script for smaller lightweight / embedded distros (usually coupled with busybox). Since the existing udev scripts will not work we created something that should work. It was tested on Alpine Linux. There is a link in the Downloads section of the TrueRNG product page to a […]
Sales have been good the last few months and so we needed to step-up production. Sure we could have purchased a solder paste stencil. However, we are makers and we like to be creative. So we thought we would show you How To CNC Mill a sheet of 5mil brass to make your own solder paste […]
Get ready for some old school blips and bloops. Its our take on an Atari Punk Console. Check out the video on the product page for an idea of what awesome noise you can expect! Fun kit to build with the kids.
We just wanted to give a small announcement that TrueRNG’s are back in stock over at Tindie, and all future orders will now be version 2. Version 2 sports a slightly upgraded hardware design. And most importantly dual semiconductor noise junctions.
So most serial terminal applications were designed for communicating via printable ascii characters, using the high end codes for control codes. We previously recommended using RealTerm to inspect the serial data (and capture it) in windows because it seemed to be geared towards this type of application. However, most of our users (and ourselves) have […]
