Some info on my electronics projects. And probably other random things. Wednesday, 7 May 2014. A working Single Board Computer. Last Monday, April 28, the PCBs arrived. They only took a little over 72 hours door to door from Hong Kong. Pretty amazing service from DHL. And amazing service from Botech. Who have done an excellent job making up my design. Here's a picture of the five boards in their little wallet:. And here are pics of the bottom of one of the boards:. Header before verifying that I could pr...

Aslak's blog: Outline of the MAXI09
http://aslak3.blogspot.com/2015/07/outline-of-maxi09.html
Some info on my electronics projects. And probably other random things. Saturday, 18 July 2015. Outline of the MAXI09. This blog post is concerned with planning and, unlike pretty much all my posts to date, is not concerned with things I’ve actually done. My new computer is coming together nicely, at least in my mind and in some rough plans. Here is a list of what I hope will be the main hardware features:. 512KB of Static RAM. C64 keyboard controlled by an MCU. Attached to UART channel). 4 virtual addre...

Some info on my electronics projects. And probably other random things. Saturday, 13 September 2014. PCB toner transfer wrap-up, interrupts, video, and an IO board! I haven't written in this journal in two months now. I've been busy with work. The biggest mistake with the controller PCB layout was that the mains AC current for the heater runs parallel to the thermocouple trace. This seems to induce a small current in the thermocouple trace, causing a fluctuating reading. I have worked around the ...It's ...

Some info on my electronics projects. And probably other random things. Saturday, 7 March 2015. This last few months has been a bit "scrappy" on the projects front. I've not made as much progress as I'd hoped but have started down several different fronts and have done a fair amount of reading. To learn about implementing a DMA controller. Actually controlling the transfer is done in several steps:. Next the MPU writes to a "start transfer" register. First the source address is put in the address bus.

Aslak's blog: An FPGA dev board on breadboard
http://aslak3.blogspot.com/2015/06/an-fpga-dev-board-on-breadboard.html
Some info on my electronics projects. And probably other random things. Monday, 8 June 2015. An FPGA dev board on breadboard. In the end I ordered some additional PLCC sockets from the UK and was surprised and happy that they arrived in only a couple of days. Soldering the sockets was easy, considering the board lacks a solder mask. Possibly the use of some liquid flux helped. I was happy with the result although it is not quite perfect:. The four digits display is the common cathode type, so segments mu...

Some info on my electronics projects. And probably other random things. Monday, 21 April 2014. PCB ordered, and improvements to homemade PCBs. This last month or so I have been working on two fronts: finalising the circuit for the computer, and working on my home made PCB fascilities. A few tweaks and additions since my last post:. Sounder has been added, with a series resistor. This is connected to the CPLD. A "Econo reset" DS1813. The IDE port has the option of supplying 5V at pin 20. This is usefu...
