A bunch of stuff from eBay turned up at last. I probably won't have to buy a coloured SIL header ever again. More ESP8266s. Some teeny tiny PIR modules which only have a 10mm dia. Some soil moisture sensors and some USB to ttl serial converters.

on April 14, 2017 .I have upgraded the firmware and buck converter in the PIR plugpack project. The new code makes use of a ws2812 to display it's status. I have run the LED out on a very thin enamelled copper flywire so that I can use the inside of the PIR dome as a diffuser. It sits out of the line of sight of the pyroelectric sensor.

on March 8, 2017 .So I scored a failed Juniper SRX210 off eBay for $1. I figured it was worth a gamble. Well it paid off. After some testing I found that the system was not getting any juice. The input protection diode had failed short. My guess is that someone has plugged in the PSU for the POE version of this firewall (48VDC) into this non-POE firewall (should be 12VDC) and nuked it. I removed it temporarily and powered the unit up on a lab power supply to limit the current. It booted! Score!

on Jan. 26, 2017 .While I was a guest I had the opportunity to try out a charcoal BBQ for the first time. After tasting it I can see why people like it. There is a distinct flavor even without adding any extra wood for flavoured smoke. If I di end up getting one, I'll definitely invest in a chimney and fire lighters because it's a pain in the A$$ to light charcoal without them.
