Delightful – Laptopograms…
Laptopograms are images made by pressing photosensitive paper onto a laptop screen and flashing an image in a manner not unlike contact printing or photograms.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

I did this almost a year ago with a regular LCD monitor and got very different results. I did a complete how to writeup here: http://www.crazybutable.com/weblog/archives/2009/07/25/who-needs-an-enlarger-when-you-have-a-monitor/
I think it’s very interesting that he got such different contrast results with the paper and developer he was using. Also, it’s hard to tell from the smaller images but it looks like he got much better detail than I was able to get.
Around that same time period I also made my own enlarger out of an old Pentax camera and an iPhone: http://www.crazybutable.com/weblog/archives/2010/04/27/who-needs-an-enlarger-when-you-have-an-old-camera-and-an-iphone/
I wonder if he’s leaving a step out or something. I’ve used Ilfospeed and Neofin Blue before and I never got anything that looked like that. It almost appears that the fixer was bad, because it has that unfixed haziness to it.
If you scroll down he does say he used “fixer of unknown provenance”.
Yes, I read that. I guess I gave him too much crediting for assuming he would know if the fixer was actually working.
All in all, it seems like he was in too much of a rush.
Maybe when his photos fade to black, he’ll learn.
