CurrentRanger is now at revision R3! I received great feedback and several threads in the forum outlined some patterns of user behavior which led me to make some improvements and hopefully eliminate some of the issues I’ve seen people run...

The Pi Gateway software is now at v9.0.0, this release is a major new feature and bug fix release. This blog entry serves as a change log and feature review. Below are the main highlights. New Node button & sample metric generators (ex:...

I made some changes to the RFM69 library to support 10bit node addresses, and you should see version 1.3.0 available in your Arduino IDE Library Manager. Previously the standard was a 1byte (8bits) address for sender and receiver, a total...

Sunday morning I woke to an unusual amount of email asking about the CurrentRanger availability. And the limited stock was all gone, so I knew something happened. I was then pointed to to Andreas Spiess’s latest video: Thanks to Andreas...

My readers may not know that I hold dual citizenship, and was born and spent my first 19 years of life in Oradea – a beautiful city at the foot of the pittoresque Carpathian Apuseni mountains and in the western part of Transylvania...

RaspberryPi projects are always lots of fun, and when combine it with displays, 3D printing and Moteinos, the result can only be awesome! I had an older RaspberryPi and a touch display, and I wanted a portable IP camera monitor...

I’ve always wanted a fast auto-ranging low-burden voltage current meter. You may find expensive high end bench meters which can auto-range they may be slow or lack the bandwidth to capture fast dynamic loads that go through several orders of...

There are now a few more breakouts available in the shop. With the release of MoteinoM0 I also wanted to make available a few boards specifically designed to mount flat on the M0 PCB for a super compact wireless sensor...

I have an Bausch & Lomb optical Stereo-Zoom (SZ4) microscope which is a great instrument and not a luxury when you do a lot of SMD prototyping and repairs. The light solution for this was a simple piece of white...

I prepared a complementary video to cover all the basics of the LoRa and RFM69 transceivers used on Moteino boards. I concentrated on the most common topics I’ve seen show up in the forum and in support emails. This should...

Since my LE40-V Pick & Place machine’s factory PCB holder is difficult to use, has no support, and is not well suited for V-scored panels, I had to get creative and use neodymium magnets on a metal plate to hold the PCB...

I’m pleased to introduce a new version of the PCB Dipole Antenna, a significant upgrade from the previous version. This has a nice VSWR of almost 1.0 at both 868Mhz (at default 78mm length), and 915Mhz (trimmed at 73.5mm). It...

The LE40V pick & place PCB holders consist of 2 adjustable brackets that are meant to hold the PCB tightly on 2 sides (let’s call them TOP and BOTTOM) while the machine pounds the panel with parts. Typically you’d set...

Do you have a laser cutter? Do you need an emergency shipping box? The USPS Priority Small Flat Rate Box has a nice template that can produce an easy to cut resizable box from the endless supply of throw-away cardboard...

The full SwitchMote kit is available again. I had to redesign the PSU cover and some 3D printed spacers which fit the new PSU R3. Everything is pretty much the same as before, except that there’s significantly less soldering to do....

If you’ve watched the forum, it’s been suggested to develop a new Moteino board featuring new/more powerful/more flexible or even ARM microcontrollers. Mentioned candidates were the Atmega328PB, STM32, SAMD from Microchip and perhaps others were mentioned over time as well....

The SwitchMote PSU is now at revision 3, here are the changes: DC side is now SMD assembled, no more through hole components 2OZ copper PCB with the RECOM RAC02-05SGA there is no need for a fuse, only a MOV...

There is a new Moteino Arduino core package release (v1.4.0). If you’ve used the Moteino package so far with the Arduino IDE, you should get a little notice next time you start it up. By the way the link to...

The LowPowerLab RFM69 and SPIFlash libraries are now published to the Arduino Library directory, and available to install in the IDE’s Library Manager (under Tools>Manage Libraries). Note that if you already have these library installed manually, you may need to...

The WirelessProgramming GUI is now at v1.6. You can find and download it here – it is part of the RFM69 library. Here are some changes: protocol improved to support variable HEX record length various other minor bugs fixed removed...

I posted a short illustrated guide for making your own Moteino from SMD components. It also includes details how to burn the bootloader and fuses. Check it out here. Thanks and credit goes to forum user LukaQ for his contribution...

We’ve had two of these iPad keyboards and they are quite nice other than having a very poorly designed corner holders. Needless to say they broke within just days after purchase, nothing surprising with kids in the house. I haven’t...

After you finally figure out the right settings and calibrate your 3D printer head and it makes prints that stick very well to your printer bed, it’s time to figure out how to remove the prints without damaging them. I...

To those that have concerned over the utility of my IDE add-on’s utility, I would like to follow up and give an example of production board batch testing at a very simple level. A simple pogo (spring loaded probe) jig...

This post is about mainly sharing the experience of a small maker business sourcing genuine components right here in the USA. Sourcing and stocking the right components in the right quantities is one of the finest balancing acts in a...
