The keyword geek: A transceiver for not a lot
http://thekeywordgeek.blogspot.com/2015/05/a-transceiver-for-not-lot.html
I used to fettle dictionary web sites. Now I chase dreams. Monday, 25 May 2015. A transceiver for not a lot. I've just built a transceiver for the 4M amateur band. QRP(low power) and AM, it's not going to be something I'll work DX with, or indeed given my rural location not something I'll work *anyone* with, but I've had a lot of fun making it. My starting point was a 2M QRP AM transceiver courtesy of G3XBM, the ' Fredbox. Subscribe to: Post Comments (Atom). From the Language Spy Shop. Other things I do.

The keyword geek: Musings on online selling of electronic kits
http://thekeywordgeek.blogspot.com/2015/11/musings-on-online-selling-of-electronic.html
I used to fettle dictionary web sites. Now I chase dreams. Tuesday, 17 November 2015. Musings on online selling of electronic kits. Earlier this year I started Language Spy while fresh from years in a permie job, to bring the fruits of computational linguistics to the masses. The first product - political trend analysis. For UK and US politics - made its debut soon afterwards. So the Language Spy shop. Logging into Tindie and going through the product set-up process was straightforward. They take 5% ...

The keyword geek: Raspberry Pi RF breakout kit on Kickstarter
http://thekeywordgeek.blogspot.com/2015/06/raspberry-pi-rf-breakout-kit-on.html
I used to fettle dictionary web sites. Now I chase dreams. Friday, 26 June 2015. Raspberry Pi RF breakout kit on Kickstarter. So, I've done it. Put the Raspberry Pi RF board on Kickstarter. The thing I said I didn't think would work out as it would put me into VAT. In the end I decided I'd have to sell a huge number to reach the VAT threshold so it was worth the risk. Time will tell how good a decision that was. What have I learned from putting it all together? So here I am, all bases (I hope) covered...

The keyword geek: July 2015

I used to fettle dictionary web sites. Now I chase dreams. Saturday, 18 July 2015. A practical antenna testing range. If you have an interest in antennas it can be very illuminating to take real-world antenna measurements. This post describes a simple set-up to allow practical VHF and UHF antenna measurements on a budget. And an attenuator network. I calculated that my 47R-470R-47R Pi network resulted in an output around 0.03 mW, or 30 μ. This resulted in a detectable RF field that was entirely within th...

The keyword geek: April 2015
http://thekeywordgeek.blogspot.com/2015_04_01_archive.html
I used to fettle dictionary web sites. Now I chase dreams. Wednesday, 22 April 2015. An inexpensive video RF modulator. This is a description I wrote a few years ago of my RF modulator for displaying video on older TVs that don't have a composite video input. The Grundig telly mentioned and the cheap DVD player that prompted the build are both long gone, but the modulator is still a very useful piece of kit that gets used for a variety of video sources. Audio This pin takes a line level audio input. ...

The keyword geek: November 2016
http://thekeywordgeek.blogspot.com/2016_11_01_archive.html
I used to fettle dictionary web sites. Now I chase dreams. Wednesday, 2 November 2016. Fixing a vintage Singer sewing machine motor controller. With my work writing for Hackaday. This blog has been rather neglected of late. However there are still a few things to write about on a personal basis, and this is one of them. Cover off, dead capacitor with brown gunge. The capacitor is a pretty standard mains suppression capacitor, a 0.1 microfarad item with a 250VAC rating. It's the voltage rating tha...If yo...

I used to fettle dictionary web sites. Now I chase dreams. Sunday, 8 February 2015. When open source software goes astray. I have just spent about half a day installing and configuring the latest version of Apache Cordova. I've used Cordova for several years now, it remains a great way to write a cross-platform mobile app. The reason for this article though lies in the first line. I spent half a day. Not an OS distribution! Every open source project risks this pitfall as a side-effect of success. Peo...

http://thekeywordgeek.blogspot.com/2015_08_01_archive.html
I used to fettle dictionary web sites. Now I chase dreams. Monday, 10 August 2015. Anatomy of a failed Kickstarter campaign. I put a simple electronic kit for the Raspberry Pi on Kickstarter, it didn't succeed. P&P made it look expensive, and I set my target too high. I'm wiser for the experience. All was good. Suppliers sorted, good social media reaction, let's put it on Kickstarter as a kit. To the last fraction of a penny. Horror stories of KS projects who'd not accounted for postage and packing a...
