eDay – Gateshead Library 29th September 2012

September 30, 2012

I’ve just about recovered from helping Newcastle Maker Space put on a great makers event at Gateshead Central Libraries eDay

We had a really great day. Thanks to all the makers for helping out and to  Gateshead Libraries for asking Maker Space to get involved.

We had not one, not two but three 3D printers on the day. A big thanks to Paddy, Cay and James for bringing them along. They spent the entire day printing out glyphs and minecraft blocks for the kids who thought the 3D printers for great.

Ed and Iain were doing Arduino stuff in the other corner and Brian, Chris and myself were manning the Raspberry Pi tables.

We had a nice crowd, over a 150 by my estimation. At most times during the day all the 7 Raspberry Pi’s we had set up were being used by people. The kids liked to program in Scratch no doubt showing off to their parents  and were happy to play the retro games we’re had the RPi’s emulating.

We were busy from the start, right up to about 2.0pm when things started to trail off. Every thing went well, even the youngsters braying the crap out the raspberry pi’s and their keyboards and mice didn’t stop the show. Hoorah for the plastic cases 😉 The big screen
projection worked a treat. We had the 3D printers and RPi media playing on it for all the day.

I spend my entire time talking to ICT teachers who were really, really interested in getting the RPi into their schools.

We had big Maker Space banners on the walls which made a great impression and there was talk of making eDay a regular event.

Only thing I forgot to do was take some pics, so I hope someone can post some pic’s on the Maker Space’s wiki for us all to see.


MiniPiio L293D board v0.10

September 7, 2012

** UPDATE: You can get these boards at tindie.com in the DTronixs store **

Here’s the second of the new Raspberry Pi MiniPiio add-on boards.

This is a DC Motor controller using the venerable L293D from ST (and others). The L293D is dual H-Bridge driver capable of driving 36V DC and 600mA per H-Bridge.

The board was designed in Design Spark PCB and the schematic is here.

Here’s the L293D board fitted to a Raspberry Pi:

and here’s the L293D and RPi driving a pair of small DC motors. Hope fully this will be a small robot in time for e-day the Newcastle Maker Space is talking part of at Gateshead Central Library on 29th September.


MiniPiio Relay2 Board v0.10

September 7, 2012

** UPDATE: You can get these boards at tindie.com in the DTronixs store

I meant to post this a few weeks back but holidays etc. got in the way, so here it is now.

So here we have a simple two relay DPCO board. Either of the relays can be selected from 8 off the GPIO pins from the Raspberry Pi expansion header.

Circuit schematic is here

and here it is on a Raspberry Pi
