I order a lot of odd items, mostly electronics related, from eBay. @WrathZA gave me the idea to start documenting what arrives and when for those of you who are curious about what you can get, the quality of the items and how long these items take to get here.
Today I had 14 parcels (originally thought it was 11 until I saw a few got stuck together) all arrive at once at the post office, this is a new record for number of parcels in a week and I assume has a lot to do with the recent problems with international shipping and the SA Post Office.
Â My ESP2866 wifi module arrived, this particular module is nice as it has most of the GPIO pins available. By default the module has a serial interface that makes use of AT commands sent from your microcontroller to use Wifi, personally that seems a bit of a waste as the module has a nice powerful CPU built in.
A quick write-up on the rfduino which arrived yesterday.
The rfduino started life out as a kickstarter project to make it easy for hardware tinkerers like myselfÂ to get access to BLE and incorporate it into our projects.
My rfduino pictured next to an SD card for scale.
It consists of a Nordic Semiconductor nRF51822Â chip, support circuitry and Bluetooth chip antenna all on a nice tiny board. The nRF51822Â contains a custom boot loader written by rfduino which when combined with an add-on to the Arduino IDE allows you to code for the device as if it was an Arduino device. This means you don’t need the Nordic Semiconductor development kit or API’s but does limit what you can do with the nRF51822 slightly.

Why Minority Report was spot on | Technology | The Guardian How some of the technology from Minority Report is coming true… Although I read somewhere that Spielberg actually spoke to various people and got ideas from things that at the time were being researched or there were basic prototypes of.
Sprites mods – CP/M on an AVR – Intro Awesome project to emulate a Z80 CPU on a AVR microcontroller, this could be very interesting as the Z80 was used in quiet a number of early computing devices.
DPAC Awesome alarm clock – The clock has a wifi connection and connects and looks up events on your Google Calendar. It also has an FM radio and built in amplifier and switch system that allows you to play music from iPods etc.
