Wacom One with Pressure Sensitivity
by Dennis Payne June 10, 2023

June 10, 2023

I bought a used Wacom One a while ago. It is a drawing tablet (not a standalone tablet as it needs to hook up to a computer). It has an display that you can use the stylus on. You can find some examples of my bad art on mastodon: https://cdn.masto.host/mastodongamedevplace/media_attachments/files/110/413… https://cdn.masto.host/mastodongamedevplace/media_attachments/files/110/469… Recently I finally determined how to turn on the pressure sensitivity in gimp. If you go to Edit->Input Devices, you can enable "xwayland- tablet stylus". (Obviously it probably has a different name if you aren't using wayland.) Once enabled the "Dynamics" setting in Tool Options takes effect. You can choose from a large variety of options. For example, "Basic Dynamics" makes pressure affect opacity and velocity affect size. I've been using "Pressure Size" which simply makes pressure affect the size of the pencil (or other tool). It probably hard to tell from this scaled down image but the lines for the eyebrows have a different thickness from the larger outer lines. I used to have to edit the tool settings to do that so this is nicer. I'm sure a trained artist could produce better output. https://cdn.masto.host/mastodongamedevplace/media_attachments/files/110/510… -- Dennis Payne dulsi(a)identicalsoftware.com https://mastodon.gamedev.place/@dulsi

June 8, 2023

Hey Gang! We've got a meeting tonight! Time: 7PM Date: June 8th, 2023 !!LOCATION CHANGE!! WE will be meeting in the Morgan student center. I think the best option is to meet on the quad side of Morgan until we can get let in. Cara has reserved a conference room. Virtual location: https://meet.jit.si/WlugMA Cara Salter is going to show off her flipper zero. If you don't know what the flipper zero is, you're in for a treat. You can check it out here: https://flipperzero.one/ As they call it, it's a multitool for geeks. As usual, I'll have snacks and refreshments and afterwards we'll head off for dinner. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Shippy 1984
by Dennis Payne April 29, 2023

April 29, 2023

I was playing around with Shippy 1984. It is a Space Invaders/Galaxian style game. It is available on Fedora. It's pretty ugly. I decided to play around with a graphics update. Not all of the changes are in git yet. Some refinement is still needed. https://youtu.be/ZAzFP90lgW0 -- Dennis Payne dulsi(a)identicalsoftware.com https://mastodon.gamedev.place/@dulsi

solar/energy monitoring
by Chuck Anderson April 28, 2023

April 28, 2023

I use IoTaWatt (http://iotawatt.com/) for solar/energy monitoring at home. It works with a standard web browser (no app required) and doesn't require any kind of Internet/cloud connection (but can use one if desired). It will keep years of data internally on the SD card and you can make pretty graphs from your phone/laptop/whatever web browser, or you can download the data and do whatever you want with it. It is an open source software/open hardware design by a guy in New Hampshire. It is manufactured in the US, and it is ETL certified. ("The hardware is professionally manufactured in an ISO9001 contract facility in New Hampshire, USA. The base units are ETL safety certified to UL standards") See pics of my setup here: http://www.wlug.org/files/iotawatt/ $314.30 gets you a US 120V bundle with split-core CTs for 14 circuits (2 mains + 12 branch circuits), 9V AC reference transformer, and USB power supply. The split-core/clamp-on CTs are easy to install, just open them up, place them around the wire, and close them. If you use non-split-core CTs (not included in the bundle above), you need to to disconnect the hot lines from each circuit breaker to slip on the CT, then reattach to the breaker.
