Bad art. Electromechanical doodads. Stats.
What I’m building: Ganglia
Yes, I know there is a network monitoring project called Ganglia. That’s not this. Move along now. I’ve dreamed about building this for about 20 years now (see earlier post). It’s a musical/sound sculpture instrument that consists of 10-20 noise makers distributed around a room. Many of them will have the ability to play backContinue reading “What I’m building: Ganglia”
Fun with Driving Solenoids
I got frustrated trying to figure out the best way to drive some solenoids. I was looking for something foolproof that I didn’t need to design myself. I’m trying to build as much as I can with JLCPCB Assembly which limits parts. I settled on the Infineon BTS724G. It’s an automotive part that has allContinue reading “Fun with Driving Solenoids”
20 years in the making
I tried to start this project back in 1999/2000 when I was living in San Francisco. It was inspired by a piece I saw in the gallery at Cellspace https://www.foundsf.org/index.php?title=CELLspace. The piece was a fantastic little music box about 4 inches by 6 inches. It was filled with a microcontroller and all sorts of electromechanicalContinue reading “20 years in the making”
Comparison of Firewalls for Home
I’m curious about firewalls. I have a Protectli FW4B along with a backup edge router ER-X and decided to do some testing. There are a handful of different ideas I wanted to explore. The first had to do with the value of the next-generation firewall capabilities like threat protection. Practically, it doesn’t matter that muchContinue reading “Comparison of Firewalls for Home”
IPFire and Centurylink Fiber
I recently switched from pfSense to https://www.ipfire.org and got to learn the hoops needed for PPPoE over a vlan like Centurylink needs. In IPFire this is considered a VDSL connection and isn’t available during the guided setup. But overall it’s a pretty easy process. You’ll need your PPPoE username and password from centurylink to getContinue reading “IPFire and Centurylink Fiber”
Kindle Oasis holder for Levo Book Holder
I have an older Levo Book holder. If you enjoy reading books and value your neck, I highly recommend this product. I get no kickbacks from the company for this, just a very satisfied customer (https://levostore.com/collections/levo-for-books/products/levo-book-holder-floor-stand). I have an older holder and can no longer purchase parts for it. Therefore I went ahead and designedContinue reading “Kindle Oasis holder for Levo Book Holder”
Medication Alarm
I take medications. I’m also very sensitive to medications therefore I take them in liquid form so I can get the dosing dialed and just right. But I have a dilemma. They all look very similar, several of them even begin with the same letter, but I take them at different times of day. AfterContinue reading “Medication Alarm”
Running HAM Radio cables
I’ve been struggling with running my radio cables through the wall. For many years I drilled some holes in the frame that held our cat door, but as you can see below, we stopped using the cat door. With the recent bout of horrible wildfire smoke here in Seattle I was forced to remove theContinue reading “Running HAM Radio cables”
Configure IC-7300 with HRD and SDRuno as a panadapater
I have an MFJ-1788 Mag Loop antenna. I can tune it very easily by using my RSPdx to view the waveform. In the picture attached you’ll notice that the antenna is tuned a little bit high for my current frequency. This makes it super easy to tune without worrying about having to put signal outContinue reading “Configure IC-7300 with HRD and SDRuno as a panadapater”
Holder for new Pi Camera
The creativity of 3D printing! One of the things I love about 3D printing is the creativity of it. I didn’t want to print any supports, so by putting a flat spot on one side I could print it with no cleanup needed.
3D printed adapter
Needed and adapter to connect my vacuum to my belt sander. Tada.
Fixed the CNC mill…again
One the disappointing aspects of doing your own CNC conversion is that you are the manufacturer. Need to know the limits of your machine? Go ahead and start running tests until something breaks. Rinse and repeat.
