ESP32 getting started..

June 28, 2017

I’ve been playing around with the ESP32 modules I got last month. Getting ESP32 working with Arduino IDE was pretty easy (see link below). I’ve now on to harder things, getting the ESP32 SDK and Eclipse installed.

Here’s a few links to ESP32 sites I’ve found useful:

ESP32 at last

May 29, 2017

After a couple of failed attempts I’ve finally got my hands on a ESP32 module.

My first couple of ebay purchases failed to arrived, which is becoming a regular thing with ebay at the moment.

I’ve got a couple of ideas for using the WIFI in a standalone WIFI hub, so its time to fire up the soldering iron


Maker Faire UK 2017 report

April 26, 2017

Maker Faire UK was another great success this year


Countdown to Maker Faire UK 2017

March 28, 2017

It’s hard to believe but Maker Faire UK is almost upon us again.

It’s on this Saturday and Sunday 1st and 2nd April at the Centre for Life in Newcastle.

Full details are here:

I’m planning on taking my latest Raspberry Pi Synth along, something I’ve called unimaginatively PiZynth. As well as the pi synth I’ll have my Pi based R-Kade Mini.

So two full days of maker stuff to look ahead too. 🙂


Sick of Beige (SoB) board – RS232, 2-ch Relay and Prototyping board

February 25, 2017

Following on from last months post about my SoB DB9 breakout board I’ve design a few of more SoB breakout boards using the DP5050 footprint.

sb_relay2_small

The first is a 2-channel Relay Board. It has two relays with LED’s to indicate when they are active. Using it is pretty easy as it features the choice of screw terminals or pin headers to interface to it.

sb_rs232_small

The next is a universal RS232 breakout. I call it universal as all the pins (8 in total but not ground) from a 9-way RS232 DB9 are broken out onto pin headers. To connect up to these are the 4 signals (T1,T2,R1 and R2) from a MAX232 (or equivalent) RS232 chip. So you can swap around the transmit and receive and handshake signals as you like.

sb_protoboard_pcb_small

The next board is just a classic prototyping board. There’s not much too say about this board.

sb_sympsu_pcb_small

The last board is a symmetric power supply for rectify AC voltage into positive and negative DC supply rails. I’m hoping to use this for a audio project I’ve got in the works.

Dangerous Prototypes (DP) have a great page describing the various PCB sizes here:

Sick of Beige (SoB) board – DB9

January 9, 2017

Whilst looking to build some breakout boards I remembered the Sick of Beige (SoB) “standard” of PCB footprints designed by Dangerous Prototypes. DP have made a really cool set of PCB footprints in various sizes with the added bonus of being designed to be case friendly.

sb-db9_2_small
My first Sick of Beige (SoB) board is SoB DB9, using the DP5050 footprint. This is a handy little breakout board for those wanting to build their own 9-way D-Type interfaces be it for RS232, RS485, CAN bus or any other project.

A standard 9-way D-Type (Male) connector provides the interface with 3.5mm Screw Terminals connections provided for easy interfacing. In addition a Male Pin Header connections is also provided. Two small circuit prototyping areas are also provided.

Board Details:

– 9-Pin D-Type connector (Male)
– Easy to Connect Headers
– 3.5mm Screw Terminals
– 2.54mm Pin Header
– small circuit prototyping area x2
– Compatible with Sick of Beigh DP5050 footprint
– Board Dimensions: 50 x 50 mm
– 3.2mm Mounting Holes x4

Uses:
– Industrial Control
– Robotics
– Mechatronics

As usual you can find them on my Tindie page here
