THE EVOLUTION OF MY BUSINESS/CONTACT CARD

Image
This was my very first contact card. It was printed off on paper as an afterthought as I need something quick before I left for an event in Southampton where I would be showcasing my android chatbot app. I handed a great many of these out but have deliberately kept a few back to remind of an important lesson that day. I learnt something very important at that event, and that was you don't have to have everything completely polished and complete. If you have a good idea and you're enthusiastic and have the right intentions, people won't mind receiving your details on a slither of paper. It was time to get some proper cards made up though in time for my next event. As I try and achieve things for as less money as possible with whatever I do, I found an offer online for free business card sample packs and took advantage of it. For years now I've been branded with rockets, rusty rockets and have done ever since I chose my first Hotmail email address back in the l

FM TRANSMITTER HACK TO BOOST THE RANGE

Image
I have always thought there is huge potential in transmitting data over the FM bands, especially when it involved one of my kite ideas. I once came up with the concept to fly a bunch of sensors via kites that would relay the information down on the ground via a low powered FM transmitter. This could then be adapted to broadcast your own recordings should you be at the beach with friends and wanted to broadcast your own radio show to the listeners below. There are many similar projects out there, take this Raspberry Pi project  here  for example. After buying a number of the old in-car FM transmitters from a car boot sale recently I decided to revisit this project and test it out only to find that the range of the things wasn’t very good at all. Although the older generation in-car FM transmitters are rumoured to have a better range than the more modern solutions, I was still only achieving a few metres. So I set about modifying the FM transmitter to see if I can boost its range some

Amateur Radio Foundation Licence

Image
Radio has always been an interest of mine from a young age and it's probably the main reason why so many radio related projects feature on this blog. As we all have time on our hands at the moment, I decided to put the time to good use and study for my amateur radio Foundation licence. Not knowing where to start, I turned to Google and quickly found the Essex Ham group who offer a free training course. I signed up with them and even joined them on a couple of their live Q&A sessions. Now Essex Ham are a really interesting group, have you ever met someone who is just genuinely so nice and helpful? Well, that describes this group, they are simply marvellous and give up their free time to help promote the hobby and tutor people who want to learn.  Due to the pandemic, the Foundation exam consists of only the theory exam as the practical element (that would normally take place at a group club meeting) can't be carried out but I still found that studying for the theory alone wa
