    Well, here it is mid August and my hacking is in full swing despite having company stay with my wife and I for a while and even through a cat 1 hurricane. Just was informed last week that two of my entries in the "Making Tech At Home" contest made the top thirty. Waiting to find out what is in the grab bag prize.

    The LLTP processor build is coming along better than I expected as I have the Sequencer tied into the ALU and Accumulator to create a very basic Load function. So the first instruction is LDA - Load the Accumulator with the output of the ALU. There is still a long way to go with the LLTP as I am currently working on the Mux and then the Dmux and another register will follow. Beyond that is the PC - Program Counter and the IR - Instruction Register.

    I have a very good outlook on the future for the LLTP. At first I was not truly convinced that a processor could be made with my Light Logic gates but now with the success I have had to date, I firmly believe that a complete CPU can be made without any transistors or relays. Diodes and resistors rule.

  • A little hacking story

    Hope that life finds everyone here safe and healthy. I just recently finished up a bit of a hacking job that was a bit out of my comfort zone. Back about a month ago I found a free TV at my local thrift store. It is a Philips 42 inch LCD 42MF521D/37 from 2009. No power at all and once home I removed the back to reveal the power and control boards. The power supply board fuse checked out good but there four filter caps that had vented and bulged, I could not see any other signs of failure so ordered up replacement caps from Mouser.

    Low and behold, that was all that was wrong with it. The set now works just like it came out of the box and works great :-)

    Never pass up on a free non working item as you never know how easy it might be to bring something back to life.
