After getting very excited by my first foray into PCB design and manufacture, I came up with a v2.0 design, still based on the original ShrimpingIt schematic. This time the board is single-layer (I wanted the routing challenge), it has a power LED (rather than one attached to the IO pins), and a reset switch.… Continue reading PCB Fabrication Version 2
For a while, have been a follower of ShrimpingIt (http://start.shrimping.it/) and their incredibly simple design for using and programming an Atmel 328p, from the Arduino IDE. I’d used genuine Arduinos previously, but was looking for something more light-weight in order to build into and around other prototypes. The ShrimpingIt design was simple and reliable, with… Continue reading Fabricating My First PCB
So we got one of those “Grow Funky Veg” kits for Christmas from a friend. A lovely gift, as we’re keen gardeners. We sowed some of the seeds inside, and some outside in a container. The most vigorous outside is by far the Mizuna. It grows like crazy. I have never come across it before,… Continue reading Mizuna
I generally get my electronic components from: Tayda Electronics.com Tayda are fantastic. Great quality. Often you get 15% off by looking out for the monthly code on their Facebook page. Ships from Thailand. I use the Thai Postal Service (rather than FedEx / DHL / other more expensive couriers) eBay I generally use eBay if a) Tayda… Continue reading Where I Buy My Electronics
To program my ESP8266 modules (ESP-07 mainly) I use: Arduino IDE as the dev / prog environment Arduino Core (https://github.com/esp8266/Arduino) as the framework A 3.3V FTDI (USB to Serial) adapter And this schematic: I don’t personally use DTR and RTS connections, as I usually have a flash and reset buttons on the board I’m working from.… Continue reading Programming the ESP8266
Strawberries. Jam sugar. A lemon. Easy right? We’ll, sorta… I got a jam and sugar thermometer for Christmas and had planted a load of fruit trees in the garden this year – so I knew I wanted to make jam. I wasn’t quite sure how to go about it at the time. But I’ve done… Continue reading Making Strawberry Jam
ESP8266 is power hungry at times – this is what I learned about using capacitors.
