Hi Mark, You are correct. It is a toroidal transformer! I was informed of this today when I was on the phone with a few transformer manufacturers. This is what I get for staying away from this side of tinkering due to fear of getting zapped. (This has inspired me to do some more learning...

Hi all, I am currently repairing some Linak Controllers for some hi-low massage tables, and I inserted a teensy into the control board so that it can be controlled remotely. The entire set up is a unit consisting of two PCBS: PCB1, power input and stepdown. PCB2, control board that sends DC...

Hi All, Thanks for the comments! Regarding the number of pots, I'm just running 8 that are going directly into their respective pins. No multiplexers for this one. Regarding the large value spikes, I was able to curb this via modifying the ResponsiveAnalogRead library via its default...

I believe I had tried it at one point, but eventually removed/commented it out. I'm using a Teensy 4.1.

Hello, I'm currently in a bit of a pickle regarding a batch of 60mm, 10k linear potentiometers that I received. For this application, I have used some Bourns sliders in the past; however, there were some changes in the availability/manufacturing of those parts: the specific item skew is no...

Ya, after reviewing my options, I just went with a STM32 chip. It pretty much has everything that is needed, and it avoids the exact issues you outlined, because those were giving me some anxiety. Really, me trying to go the other route was an attempt to avoid prototyping with any SMT...

Hmmm. It looks like my best bet is probably to use a USB to i2c bridge. It looks like there are plenty of decent options that can function as i2c masters, with a comfortable amount of GPIO available, which means there is more than enough expansion available for each module to have whatever i2c...

Hi All, I'm currently in the planning phases for a new project that is going to require hot-swappable PCB modules with various I/O on them: Some switches, encoders, screens, and I believe some sensors—the type are yet to be determined. I was originally planning on using an ADS7138...

Looked into some more of the bourns encoders, and they appear to have some optical ones as well now: https://www.mouser.com/ProductDetail/Bourns/EM14A1D-C28-R032H?qs=sGAEpiMZZMv5XWiOWIxhpCGiFeRbpVwfui9DcN9JPpd%2F5UwOrwJ6VA%3D%3D - 32PPR - 32 Detents - Hard Switch...

Thanks for the reply! Price per encoder doesn't really matter in this case. Function is more important than anything, as these will be used a ton. Overall, we are trying to keep the form factor of the entire device down to something below 6"x 6". Something that we can easily move around desks...

Hello, New to making things with teensy, and while I have experience soldering synth kits, I'll admit my electronic knowledge is fairly rudimentary. I have been asked to create a small controller to control the output volume of a studio's speakers. Since they want it to be fairly precise, I...
