It's fun that doesn't get in the way of work. In this metaphor, chocolate coating on your dessert. For the record, I disagree with the author on the uselesnes of syntax highlighting and would like to see an actual study on the topic.

Ironic how a famous musician did something nearly identical to this years ago.

Also something even more intriguing is that his name was displayed on the screen as well!

I'm glad that acid head is still getting his "wobbly legs" and licking windows.

Hail the Analord!

Master Linus, I'm trying this (for HDMI out from Android phone to vga monitor):

https://sites.google.com/site/scidiy/pc-diy/hdmi-to-vga

As none can see anything in the section "How to wire it up:", can anyone show us? (that site has no way to contact (or know who is) the owner...)

I'm wondering here, can someone draw the schematics using that thinking, with the suggested improvements:

a) The original project uses software to generate the H/Vsync signals and thereby it uses up 2 valuable GPIO's. So we need to generate these signals with a couple cheap and simple oscillators (NE556). The maker chose to generate them with software but maybe it is more convenient to do that electronically with a NE556 dual timer IC.


1) added the DDC lines, 5V and 1,8V lines including voltage converters for the DDC lines on mine based on the sparkfun i2c level converter.

2) For the R2R ladder would maybe save some money if instead of using resistors of double the resistance, just put two in series? I do that with R2R DAC's for VGA and sound production. For example, interfacing with a VGA I use a bunch of 270 ohm resistors to approximately match the 75ohm impedance of the VGA. For audio, I use 10K resistors mostly. SMD resistors on a roll, are usually from the same batch, so they are pretty well matched. Saves on buying 1% types, but the price difference between 5% is small anyway. (Saves room too, for those who desire smaller mountings)

3) Option: Using two 2R's in parallel to make the R's
And a there are less R's than 2R's,
so less waste than putting two R's in series to make 2R

4) Or one could try to use a FMS-3818 tripple dac

Can anyone? Thanks.

Genialt!
Hittade just den här sidan via YT, helt otroligt häftig konstruktion.
Jag hoppas att du någon dag gör ritningar osv. tillgängliga.

Why don't you a kick starter or something ?

Are planning on builds, I notice the vid is from 2011

I really want to buy You an Amiga 500, i'm sure that U can make a PS3 emulator on it! GENIUS!

Hi Linus,

I've just watched quite a detailed talk about the 6502, that I thought you'd sure like (https://www.youtube.com/watch?v=K5miMbqYB4E). More info is available at visual6502.org. They've analyzed and simulated the chip based on high-res photographs.
