We made leather pen sleeves, and a sunglasses case. Various finished leather stitched with tiger thread. Much fun was had!
Nick, your new approach of breaking the HAAS class into three segments seems to be successful. It seems like lot of people have completed their domino - it seems to be better than under the old approach. Kudos!
thank you. I can’t take all the credit but it sure seems like we’ve got a bigger success rate than the old system.
Not much to show yet but the tools at DMS are procreating! Between Walter, Inventables, and Shapeoko I have all the parts for my X-carve. Working on the gantry tomorrow…then I can return to beating my head on the wall with the laser and 3D printer repairs lol
Did you leave sone X-bar in electronics? If so, it’s now at lost and found.
After taking the class Thursday, I stayed back after and successfully completely the class practice turners cube!
Special thanks to @nicksilva for giving me a one on one last week to get my sherline training and to enable me to take the class and to @wandrson for offering such a great and challenging class! Looking forward to making my next one out of the brass cube!
Nah it all got delivered to the house and I’m trying really hard to assemble it here…that said I think once I’ve put together the X-carve/Shapeoko I’ll have a better idea how to solve the issue on the little laser. I did post getting the other two calibrated as a job opportunity though and am willing to pay someone else because the donors of both machines would like them used ASAP and I don’t have time to work on all three with my learning curve
Not finished yet but I’m very happy with where it’s going. American elm burl with cherry and ebony lid.
Looks great! Glad you found a good use for the burl! That burl has been waiting for someone to use it for 20 years.
Ooooh lovely. I particularly like what you’ve done with the lid and the finial. They complement the burl beautifully!
Great Job! Looks good!
The electronics committee was talking about creating ‘kits’ for Arduino classes. To package the Arduino boards and breadboards, so that they were less likely to walk off, I modified my design to include the logo and property of DMS Electronis, then printed ten of them.
Making soap and soap making - results from the first class. Soap is not blurry, my photography is. On left are jasmine essence and on right are a mixed pink grapefruit and rosemary essence. Thanks Joshua for a fun class
Some “makes” are in the realm of the Virtual …
I took the LT Spice circuit class today and everyone did some simulations … here’s one of mine on my Macbook Pro … I’m looking forward to building it in the Real and comparing … (in the Real this blinks two LED’s)
Teapot and Raku Bowl each took 2nd
Brown bowl took 1st in Wheel Thrown
I think the Teapot should have been in a different category? but, it was a last day to enter, and get my stuff up there thing.
So last year this time, I taught a couple of classes on how to make a morse code radio transmitter. I am bring this class back, and plan to teach it about once per month. There are still four seats available for the September class

At that time, I also started working on a design for a matching receiver, but ended up abandoning it because I thought it would be too much to get built in a single class.
Well a year of contemplation later, and a bit of nudging from @zmetzing and I have a new approach. The idea is to break the receiver into individual modules, and take each module as a single class. I believe this will be a more manageable approach. If each module class is offered regularly, then people can come to the classes they can and build their radio as they can.
A direct conversion receiver only has a few needed modules. Basically four (the RF Preamplifier is optional).
So yesterday, I started at the right side of the block diagram (that way you can use what you have built to test the new module) and created an audio amplifier module. Basically a NPN preamplifer and an LM386 amplifier. I am packaging these modules in custom 3D printer holders to allow for swapping them into and out of various radio designs.
Today, I finished building and testing the second module; a product detector built with a dual gate mosfet arrangment of two J310 JFETs. I am using a signal generator to simulate both the RF input and the Local Oscillator. The product detector takes two signal frequencies as input and produces the sum of those frequencies and the difference of those frequencies at the output. The local oscillator is tuned to be within a kilohertz or so of the RF frequency and the difference is in the audio range (that kilohertz or so), which is then presented to the audio amplifier (along with the sum which is too high a frequency for you to hear). Tomorrow I plan to create the band pass filter for the 80M band to match the receiver with the Mighty Mite transmitter.
One of the pouches from the leather hip pouch class! Should be doing another class for them in a few weeks
