We have been working on a single cell Arduino compatible LoRaWAN low power node for some time now. Many who has been following our work has been asking when will the board will be released. We have to admit this is probably one of the simplest board we have ever design but the testing and validation (whether it’s in the lab or in the real world in sub zero temperature) requires so much of attention and patience. We’ll be talking a bit on the ideas behind this board and what motivates us to perfect it in this article. Read more

Last week when we posted an update to the WISMO228 library for Arduino, we mentioned we were using the TraLog shield as a vehicle tracking & logging device. We finally found some time in between everything to write this post and illustrate what the TraLog shield is capable of. Read more

Many of you guys were asking on the availability of the Reflow Oven Controller Shield lately. We did some modifications on the shield based on users’ feedback and opinion. We had assembled a small batch of prototypes and have them sent to our maker friends out there to test them out before the final release. The firmware to support the hardware changes is also completed.

Here’s a quick post on how a board looks like after coming out from the reflow oven using our Arduino compatible reflow oven controller shield. Look at the curvy solder joints of the components. It ain’t that shinny because it is lead free solder paste. One of the main advantage is, if your solder paste dispensing (either through syringe or stencil) is at the correct amount, I’ll bet that you’ll have zero rework on the boards that came out from the reflow oven!

We hope this doesn’t look like a oven shootout for baking cakes! For the past 24 hours, we have been experimenting with different 4 ovens ranging from 800 W to 1500 W. We wanted to share our experience on selecting the oven that probably will work for your reflow process. Read more
