B-7971 Nixie Character Designer. Timelapse of No Knead Bread Dough Rising Made With My Raspberry Pi Camera Rig. I use my recently completed Raspberry Pi camera rig to capture 840 stills of no knead bread dough rising over a 14 hour period. With only a quarter teaspoon of yeast and quite a cold room, the dough rises slowly. The raspistill program was used to capture the stills and the Mac OS X app Time Lapse Assembler was used to assemble them into a video. Posted by Luc Small.

B-7971 Nixie Character Designer. Connecting the RDA5807M FM Radio IC to an Arduino. In this video I connect a really tiny FM radio receiver IC, the RDA5807M to an Arduino. This chip came on a cheap module labelled “RRD-102” from Aliexpress. I give a demo of the breadboarded circuit receiving a transmission from my now vintage Silicon Chip “Micromitter” low-power FM transmitter. The RRD-102 module I purchased for US$0.73 delivered: RRD-102 module. Posted by Luc Small. Wifi Hack for Raspberry Pi Zero.

B-7971 Nixie Character Designer. How to Shutdown Your Raspberry Pi at the Push of a Button. For my self-contained Raspberry Pi camera rig, I needed a way to cleanly shutdown raspbian linux without a keyboard or remote console. I show how a simple pushbutton and a Bash shell script with embedded Python code was be used to achieve this. Get the shell script here. Posted by Luc Small.

B-7971 Nixie Character Designer. Trying Out a PAM8403 Audio Amplifier Module. I try out a cheap amplifier module featuring a PAM8403 chip by hooking it up to some speakers and playing some tunes. This device is a 3W 3W dual channel (stereo) class-D audio amp in a SOIC-16 package. The Datasheet is available here: PAM8403 Datasheet. Posted by Luc Small.

B-7971 Nixie Character Designer. Making a GPS Breakout Board by Etching Some Stripboard. I try something I’ve never tried before - etching stripboard/perfboard/veroboard in ferric chloride etchant. I run into all sorts of dramas with cold, weak etchant that over-etched in places while under-etching in others. But a second attempt yielded an acceptable result. All’s well that ends well. Would I use this technique again? Probably not. But it was an experiment worth trying. Posted by Luc Small.

B-7971 Nixie Character Designer. Wiring Up a DIY ESP-12 (ESP8266) Breakout Board. In this video I make a breakout board for the ESP-12 wifi module using a plywood jig, wires, solder, scrap PCB, header pins, and hot melt glue. I hook up the right combination of pull up and pull down resistors, and demonstrate it turning an LED on and off in response to MQTT messages. I draw up a circuit diagram to show how things connect. The Lua code for controlling the LED using MQTT can be found here:. The idea was to ...
