New Technology

As well as collecting and restoring old electronic gadgets I own a few modern gadgets.  I also like to combine eras, so some of my projects mix old technology with new.


Nokia Internet Tablets

I've ported a few applications I find useful to these tablets - and the earlier 770.

Texas Instruments MSP430 microcontrollers

From MSP430
In the photo are three TI EZ430-T2012 boards bought from Farnell.  These boards make experimenting very easy, you just plug them in to the EZ430-F2013 USB programmer, and once programmed can run stand alone from a 3V lithium watch battery.  As supplied the boards have 14 plated holes at 0.1" pitch.  For hardware prototyping I soldered on some "header" pins from an old PC motherboard - the battery holder, cable and the small 32kHz watch crystal came from the same source.  The inspiration for this was Sivan Toledo's I2C interfaced IR remote - here.  This arrangement works fine, but I then found some 0.1" pitch IC socket strips  and  decided  that for my purposes they would be easier to work with - thin solid wire will push in, so no bulky cable required.

This looks like an interesting use for vintage tuners and receivers such as the Sound Sales DX Plus One.

I'll need to convert the signal to a 12kHz IF.  Here's a circuit using a FET - how modern!  I think I'll stick to a good old triode-hexode.

Here's a more sophisticated converter using the SA602 http://users.belgacom.net/hamradio/schemas/DRM_455kHz_to_LF_Converter_FRG-100.htm

There are sample files here http://www.g7ltt.com/drm/

and using one of these I was able to check that my install (on Ubuntu) of Dream DRM Receiver was working.
