It's been a while and I apologise to all out there about not getting this up sooner, but finally the Squishy circuit Instructions are here. These are a great way of teaching kids simple electronics and can be done very cheaply with some bits and pieces picked up in hardware stores and some electronics stores. Any questions please email us and i will endevoure to sort you out on places to buy and any queries you may have.
Conductive Dough (Last's about a month in sealable airtight container) - Can be frozen for longer periods
237 mL Water
355 mL Flour
(A gluten free version of this dough can be made by replacing the flour with gluten-free flour.)
59 mL Salt
44 mL Cream of Tartar*
15 mL Vegetable Oil
Food Coloring (optional) - Takes a little bit of guessing to get this right
*133 mL of Lemon Juice may be Substituted
1. Mix water, 237 mL of flour, salt, cream of tartar, vegetable oil, and food coloring in a medium sized pot.
2. Cook over medium heat and stir continuously.
3. The mixture will begin to boil and start to get chunky.
4. Keep stirring the mixture until it forms a ball in the center of the pot.
5. Once a ball forms, place the ball on a lightly floured surface.
WARNING: The ball will be very hot. Flatten it out and let it cool for afew minutes.
6. Slowly knead the remaining flour into the ball until you’ve reached a desired consistency.
7. Store in an airtight container or plastic bag. While in the bag, water from the dough will create condensation. This is normal. Just knead the dough after removing it from the bag, and it will be as good as new. If stored properly, the dough should keep for several weeks.
Non Conductive dough
355 mL Flour
118 mL Sugar
44 mL Vegetable Oil
118 mL Deionized water (Regular tap water can be used, but the resistance of the dough will be lower.)
1. Mix solid ingredients and oil in a pot or large bowl, setting aside 118 mL flour to be used later.
2. Mix with this mixture a small amount of deionized water (about 15 mL) and stir.
3. Repeat this step until a majority water is absorbed by the mixture.
4. Once your mixture is at this consistency, knead the mixture into one “lump”.
5. Knead more water into the dough until it has a sticky, dough-like texture.
6. Now, knead in flour to the dough, until a desired texture is reached.
7. Store in an airtight container or plastic bag. While in the bag, water from the dough will create condensation.
This is normal. Just knead the dough after removing it from the bag, and it will be as good as new. If stored properly, the dough should keep for several weeks in an air tight container or plastic bag.

A trial run from September - December will take place where the space will be open every 2nd Saturday for some project work . With the next HackSaturday being 13th September from 1pm - 5pm
Our second public event in as many years was held last weekend at the Drogheda Arts Festival. Over the course of two days we had a number of stands allowing members of the public to learn how to solder LED badges, connect everyday items to the internet, learn how to make LED Graffiti and watch our doodlebot in action! We also had a number of members projects on display including a retro arcade cabinet and an LED matrix. During the two days we also met many people interested in Lightbox Labs. It was great fun and we had a busy but fun packed weekend and we really hope to do it again next year! Here are some shots from the Saturday and Sunday.

“Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.”
With 2014 fast approaching I thought it best time to post a "2013 year in review" for Lightbox Lab. We are now in our second year in existence and we are almost a year in our current space at Millmount RDC in Drogheda. Everything we hoped to achieve in 2013 has been done. Our club bank account was created, Millmount RDC have given us the a space we need for members to work and storage of equipment and membership payment is in place.
We have also built up a steady stream of funding from membership payments, non-member donations and from various workshops we ran over the year. This allows us to continue to use our current residence and also to put aside some funding for equipment in 2014.
This year also saw Lightbox Lab become involved with other events that took place such as Coder Dojo's DojoCon 2013 in Slane Castle and the Dundalk Youth Arts festival. We also attended Gaelhack in Waterford, a new event organised by Irelands hackerspace community which we will be more involved with next year.
Plenty of interesting projects were worked on in the space during the year by members, some of which have been documented on this site. Our weekly FREE! open night on Tuesday continues to allow anyone, members and non-members alike to come in and work on their own projects or a group project, use some of the equipment or to just bounce ideas or questions off like-minded people in the space.
Our members and our regular non-members at the open night have a range of interests. From electronics, hacking and gaming to music and other creative uses of technology. In 2014 we hope to hold even more workshops and to hopefully hold more regular events during the week.
We are always interested in hearing more from people in the Louth/Meath area and beyond who would like to get involved or who are just curious about what we do. You don't have to be an expert or even know what you are doing! just a sense of wanting to learn and/or get creative in something you are interested in within an easy-going environment is all that is required.
Picking up ADS-B Flight messages ON a €40 Raspberry Pi
After listening to a talk by RenderMan DEFCON 20: RenderMan on ADS-B (Interesting talk) I came accross a few threads on how it was possible to recieve these ADS-B broadcasts using no more than a Raspberry Pi and a €8 DVB-T digital tv usb dongle.
As I had a Raspberry Pi spare I decided to see if I could get this working on my Pi. After doing a bit of research on a compatible usb dongle it transpired that I needed one that could tune into the 1090 MHz range to pick up ADS-B broadcasts. This led me to the RTL2832U/E4000 or a newer RTL2832U/R820T chip/tuner combination that tune into 1090 MHz and there are plenty of these out there on eBay. Please do double check the specifications before purchasing from the link. The one I purchased was this one.
I found a great How To guide online from a guy called David Taylor http://www.satsignal.eu/raspberry-pi/dump1090.html explaining the complete setup and following the guide worked to the letter. He explains it all fully and there are plenty of other links with further information on his site. It is recomended to use a powered usb hub but for me anyway it worked fine from one of the usb ports on the Raspberry Pi. Even using the dedicated mini areil that came with the dongle I was soon able to pick up plenty of aircraft traffic within a range of around 150 km. Impressive for €8 :) I intend to make a cheap homemade antenae when I've some time.
