News, Updates and Other Minutiae

September 2023 Long time between drinks, but not much happening on the tech front at the moment. Added another couple of rants to the rant page.

January 2023 Updated the AD9833 VFO code to use a 12F1840.

December 2022 Added rant about todays useless (internet) search engines.

November 2022 NEW Project An AD9833 Based Simple VFO. FT101ZD VFO project updated.

October 2022 A replacement internal DDS VFO for FT101Z/ZD rigs. Because the worlds postage system has gone totally bonkers and it is not possible to send a small pcb anywhere except at extreme cost, I am slowly making available the option to purchase pcb's from Pcbway. First up is the Simple DDS VFO 2017 project pcb. Others will be added over time. Noise Canceller kits available again- see Noise Canceller page.

Model Railway Electronic Project - Flouro Light Simulator - Under construction - Dec 2017

All the Model Railway Electronic Project web pages are a work in progress at the moment, so they may ramble a bit or be a bit disorganised while I refine the various pages. Most of these projects were done quite some years ago without much documentation, so I'm in the process of documenting them, which may take a little while. In the mean time, what I have is being put up here. Before flouro lighting had instant start circuits, they would flicker several times before coming on (but there was always at least one that just kept flickering). So here is a small project to simulate just that, with 8 outputs that will flicker several times and then stay on and one output that continually flickers. It can be used for street lights, office lights or just general lighting.

To do: Expand this webpage with more info. Make a small diorama and video it to show how it operates. More as I think of it.
