Hi, all.
This blog has moved to a new server, which should hopefully be faster than the old one. However, if you do come across anything that doesn’t seem to work correctly, please let me know in a comment, and I will get on to it as soon as I can.

Recently, I added solar power to one of my ESP8266 weather stations.
With the right hardware, this was actually remarkably easy to do. To make things nice and easy, I ordered an Adafruit USB/DC/Solar Li-Ion/Li-Poly charger. (Top-right in the photo) These boards can take DC input from USB, a 2.1mm power jack or from wires soldered directly onto the board. It will then both charge a Li-poly battery and power a load. Whatever power is left over from powering the load will be used to charge the battery, and if the load draws more than what the solar panel can provide, the rest will be drawn from the battery.
Here’s a quick and easy way to add a colour picker lookup to an AX form.
I’ve seen a number of different ways to add colour picker support to an AX form, but so far, this has been the easiest. It is not ideal, because the colour picker opens up as a dialog window, something which can’t be easily worked around without resorting to using custom ActiveX or .NET controls.

Last month I wrote a series of posts about reducing the power consumption of the ESP8266, showing how I got the power consumption of a weather station down to 54 μAh per 5 minute reporting cycle.
At the end of that, I thought further improvements would be mainly tweaks and fine tuning, but Tobias wrote a comment explaining that it would be possible to avoid the initial network scan happening as part of the WiFi network association. I’m happy to say that it is possible, and it works quite well indeed.

Dynamics AX 2012 introduces built-in support for resolving and looking up linked records based on reference record IDs.
When adding a reference record ID field to a form, AX will add a reference group control instead of the reference record ID, and will show a selected set of fields from the referenced table. See the posts about tree lookups for an example.
The reference group control also does lookups into the referenced table for selecting a new value. However, by default this lookup is not filtered and will show all records in the referenced table. Adding filtering is quite easy to do and it follows a similar pattern as regular table lookups.
