I originally used PCBWay.com, and had great success and fast service. Recently, they charged me $5 for 10 PCBs plus shipping. You might try https://jlcpcb.com/ they have 10 pcb for $2 plus shipping. Pricing is very competitive these days.

Nice design and more like "My New Flame".
There's a link in the Parts list to Lumiere Candles Inc.. These cylinders are made of a resin plastic with a matte finish. The look and feel of these are very much like real candles. It can worked like cast acrylic plastic, and I found it easy to mill on my CNC. Yes, several of these parts are expensive, especially the 6" H x 3" OD cylinder.I don't have a video of it in a dark room, but the amount of light generated by the LED Candle is comparable to real candle of the same size. The small LED's on the power supply are noticeable through the cylinder in a dark room.

I purchased the lasers at Aliexpress:[https://www.aliexpress.com/item/Red-Line-Laser-Module-5mW-650nm-Focus-Adjustable-Laser-Head-5V-Industrial-Grade/32915484279.html](https://www.aliexpress.com/item/Red-Line-Laser-Module-5mW-650nm-Focus-Adjustable-Laser-Head-5V-Industrial-Grade/32915484279.html)The rocker switch was purchased at Banggood:[https://www.banggood.com/20pcs-250V-3A-Mini-Boat-Rocker-Switch-2-Pin-Plastic-Button-ONOff-SPST-p-1044250.html](https://www.banggood.com/20pcs-250V-3A-Mini-Boat-Rocker-Switch-2-Pin-Plastic-Button-ONOff-SPST-p-1044250.html)

Thanks! I used Fusion 360.
The first step of the calibration procedure is to align the Laser line vertically for each laser. As a result, the Laser Guides are good for all levels of the Drill Press Table.
I've added an image to Step #5 which illustrates the principle of operation. The cross-hairs will indicate where the drill bit will contact the work piece regardless of the table height. As seen in the illustration, the laser lines form two vertically aligned intersecting planes where the intersection corresponds to the center line of the drill chuck.
The first calibration of the lasers is to align each laser lines (planes) vertically. The next step is to intersect these lines (planes) to the center line of the drill tip. These vertical intersecting planes (lines) are in the same spot regardless of the table height or distance from the chuck.It's hard to beat how well this makes drilling holes with Forstner Bits (or other large tool) when the bit obscures the spot to drill.
Absolutely, you can use any circuitry you wish to supplying 5 VDC to the lasers. I used the PowerBoost voltage regulator to boost my 3.7 VDC Li-Ion rechargeable battery to a 5 VDC output. The PowerBoost also provided low battery protection for Li-Ion battery. Your suggestion a 5 VDC cell phone charger is a simple and great idea.

I purchase resistors, transistors, capacitors, inductors and LED assorted kits for a few dollars from ebay, aliexpress, banggood or amazon. For specialty items, I go to Digi-Key.

I apologize for the error. The "from ListSelector import ListSelector" line should be removed from vac_sensor.py. Either manually remove the line, or download the edited version of vac_sensor.py from above.Merry Christmas
Also, you need to do the following:sudo apt-get install python-smbus python3-smbus python-dev python3-dev python-numpy

If you refer to Figure #2 Part B, I glued a 20-22mm thick piece of rubber between the two adapter plates (A and C) as a shock absorber between the sliding plate (#108 in Figure #1), which the upper wheel is attached to, and the load-cell.This model bandsaw has a brush to remove saw dust from each wheel, therefore, I haven't noticed any significant changes in force while the saw is in operation. Thanks for asking.

The UNO will not work. The YUN has Linux and WIFI, which are both required for this project.
