As outlined in the RF Best Practices guide, the Monopole Antenna is formed by a quarter wavelength vertical piece of wire, plus a “launchpad” ground around its base, and is a very good cost-to-performance ratio antenna. The quarter wavelength refers...

SwitchMote  and SwitchMote PSU are now available with a single 16A relay, instead of dual 10A relays. I realize this is most often the case that a second relay is not really necessary, except when replacing dual gang switches with...

  The sump pump is a device that works hard to keep your home dry but is prone to failure, and if you have any valuables in your basement or crawlspace, even a light flood can cause a lot of...

After Moteino R4 has been the long running champion of its lineup, and R5 has had a brief period of glory, Moteino has now been shipping for the past week at revision R6! Wait, what happened to R5 which was never...

In past times (see this and this post), wireless programming of a remote Moteino used to be done via a python script. This took a compiled Moteino sketch (hex file) and passed it to a programmer Moteino which would relay it...

Forum user [aw] has graciously shared a 3D printed case for GarageMote. If you have a 3D printer you can download and customize/print the model from thingiverse. The model includes the option for a chain magnet snap-on which is really convenient...

I’ve long wanted to make a professional enclosure for SwitchMote and do away with the acrylic covers and all the screws and spacers. All these parts add a lot of overhead and cost to the kit. SwitchMote was designed to...

Quite excited to announce the new PIR sensor option on SwitchMote, this was requested by a user and is finally available in the shop. The chosen PIR sensor was the ultra low power Panasonic EKMB1201111 (same as offered in the MotionMote...

Looking for a sleek RaspberryPi enclosure that also fits the ATXRaspi smart Pi power controller and a power button? Check this awesome case from C4Labs which is designed to fit the ATXRaspi along with a power button for shutdown/reboot: It includes a bunch of...

I built a few uCurrent GOLD clones for some projects, based on the original uCurrent BOM from EEVBlog. Because of the BOM is rather expensive, a handful of sets of parts were purchased and there are a few units that are available...

Good news for international customers! After a period of integration and API testing, DHL Express is now available for international orders! Pricing on DHL shipments is dynamically fetched at checkout and ranges typically from $25 to $40 to most EU countries....

John from John’s DIY Playground put together a nice video of setting up a Weather Node powered by a PowerShield from a LiPo battery, watch his assembly vide and demo below. Although you could directly power the Moteino + WeatherShield...

If you want to automatically power off your Pi when you run the shutdown command (ex. shutdown menu in xbmc), this can be done pretty easily through a small addition to the ATXRaspi circuit. Basically we need to tell ATXRaspi to...

This is a summary of some load tests I did on the ATXRaspi. People often ask: How much load can the ATXRaspi support? I used the following hardware, and I wanted to see how much current the official DSI display will...

Sometimes you need to remote control an AC outlet that powers something (like a heater or a light or motor etc). There are different IoT solutions out there  like the PowerSwitch Tail which allows hooking up your arduino/IoT device of...

UPDATE: A sample RFM69 sketch for WeatherShield R2 is posted here. WeatherShield is now at R2 and although the PCB is very similar to R1 there are some significant differences. The R1 used to have a BMP180 until Bosch decided to...

The MotionMote is now available with optional BME280 sensors and Panasonic PIR ultra low power sensors (the EKMB1201111: 5m 2uA, white). When you opt for the Panasonic PIR you get that instead of the chinese HC-SR501 with the appropriate enclosure front...

I would like to introduce the new MotionMote R3 revision. The kit will be mostly the same, with the exception that it supports some exciting new options. Read on for details. Here are the highlights of the new revision: support for Panasonic...

Cliff Batson (N4CCB) has put together a network of cycling event sweeper detectors. In a biking event the “sweepers” are the last bikers who ensure nobody in the race gets left behind. Each of the 4 routes of the HRR cycling...

James from snorp.net looked into automated blinds but when he saw the eye watering prices he decided to make his own wireless motorized blinds. He posted a great detailed tutorial to do just that. The result is motorized blinds automation device that is...

I had previously released a MoteinoMEGA with trace antenna, and there is now a regular Moteino with trace antenna. Everything is the same as the MEGA variant, except of course this is the atmega328p based Moteino, the most popular variant....

I thought this project was too good to pass and I wanted to share in the blog. Forum user G4lile0 posted a funky little robot project that is more mobile and agile than it looks in the photos – it...
