Ten-Tec 1254 Receiver Display Upgrade Kit

Posted by David on 27 April 2017

Edward Cholakian (call sign KB1OIE) makes and sells a Ten-Tec 1254 Receiver Display Upgrade Kit that is designed to upgrade a Ten-Tec 1254 shortwave radio receiver.

One of the main features of the kit is that it provides a backlit 2×20 character LCD to replace the receiver’s original 5-digit 7-segment display, allowing much more information to be shown. The kit includes a clear plastic window to replace the receiver’s original smoked dark plastic window, and a black plastic display mask. Edward gets both of these pieces made using our custom laser-cutting service.

The display/control board in the kit uses the P-Star 25K50 Micro as its processor. Edward, a consulting engineer who designs embedded hardware and firmware, told us that he chose the P-Star because he was already using a Microchip processor similar to the P-Star’s PIC18F25K50 in one of his previous designs, and it was more economical to buy the P-Star than to hand-assemble his own board. He said the P-Star’s cross-platform USB firmware upgrade software was also a plus since his own bootloading software does not support Linux and macOS.

The kit comes with software for Windows that can control the receiver over USB. The software provides a graphical user interface and uses WinUSB to talk to the P-Star’s native USB interface.

Custom laser cutting for retro-gaming TV enclosure

Posted by Ryan on 5 April 2017

One of our customers used our custom laser cutting service to cut the birch plywood panels for his retro-gaming TV system that he sells on Etsy. The birch panels are stained with shellac. The system runs on a Raspberry Pi 3 Model B, to which you can connect (not-included) controllers with Bluetooth or USB. The Raspberry Pi’s Ethernet port, SD card slot, and 4 USB ports are accessible in the back.

Science Olympiad 2017 robot arm competition

Posted by Ryan on 3 March 2017

Congratulations to Matthew Siracusa and William Rule who placed first in the Robot Arm competition of the Science Olympiad SE PA Regional Tournament last Wednesday! They used our custom laser cutting service to cut the base and structural components of the robot arm out of black ABS. We wrote about another one of Matthew’s projects on this blog when he made a 6-string banjo (that has a frame we also laser cut) as part of the 2014 Science Olympiad.

Steel custom laser cutting available

Posted by Arthur on 2 March 2017

We’ve been offering quick-turn custom laser cutting service ever since “we” were just Candice and Jan operating a tabletop Epilog out of their home. Since then we’ve cut a wide assortment of customer designs including jewelry, engraved control panels, robot chassis, Christmas ornaments, and wedding invitations.

We started out mostly cutting acrylic, gradually moving into cutting a wider variety of plastics and wood. All along we’ve been improving our processes and increasing our capabilities by buying machines with bigger beds, better control systems, and more power. Without announcing it officially, we’ve been cutting metal for customers and ourselves over the past few years. For example, we cut our Basic Sumo Blade for the Zumo Chassis and the SMT stencils for our in-house electronics assembly. We’ve been refining our metal cutting processes and finding the best cut settings to minimize the chance of burring and dross, so most parts come out relatively clean and smooth to the touch.

The process quality has gotten to the level where we are comfortable announcing that metal laser cutting is generally available to customers!

You can see in the pictures above that laser-cut steel parts have a slight discoloration along the laser-cut edges caused by the chemical reaction that takes place when cutting. Depending on the steel type and whether the cuts are through the material, vector-etched line art, or raster-engraved filled-in areas, the discoloration is different (some tend to be brownish while others are a dark gray). We do not guarantee that parts will be free of blemishes; we ship the parts without any post processing, and we currently do not offer additional services such as deburring, tumbling, or bending.

As stocked materials (shown on our quote request page), we carry #304-2B stainless steel in 0.024″, 0.030″, 0.036″, 0.048″, 0.060", and mild steel in 0.030″ and 0.060″. We can arrange to use material you ship to us, but keep in mind that steel is the only metal we can cut. We cannot cut copper, brass, titanium, aluminum, or precious metals.

GoonieBox: a puzzling piece of interactive furniture

Posted by Ryan on 22 February 2017

Customer Guido Bonelli Jr., who is also the creator of the Dr.Duino Arduino shield, had us laser cut pieces of baltic birch for a unique piece of furniture for his home: a large, interactive puzzle. An Arduino Mega 2560 R3 controls the various puzzles and contraptions packed into this piece. His article in Design News goes into more detail including a parts list and more pictures.

S3 Pilot board robot

Posted by Claire on 28 August 2015

Forum member spiked3, whom we previously posted about, has shared another robot with a custom laser cut chassis. The new robot uses his own custom Arduino shield, the S3-Pilot, which has sockets for an IMU and two of our MC33926 Motor Driver Carriers.

Custom Arduino shield created by forum member spiked3.

The MC33926 drivers control two 37D motors with encoders, and the encoder signals are processed by the Arduino. The robot also includes a lidar, PIXY Cam, and Raspberry Pi. The on-board IMU and encoders allow the robot to keep track of where it is and what direction it is facing, so spiked3 was able to implement a high-level interface for the robot that accepts movement commands like “go forward three meters” or “turn a certain number of degrees to the right”.

You can find out more about this robot and see some videos of it being tested on spiked3’s blog.

Odin sculpture and laser-cut model

Posted by Arthur on 12 January 2015

DeWitt Godfrey, a sculptor and professor at Colgate University, used our custom laser cutting service to create a 15% scale polystyrene prototype model before moving on to the final full-sized sculpture. The final installation, located on the Colgate campus, measures approximately 40′ × 20′ and weighs 13 tons. In the video above, the styrene model appears at 2:10, and again at 2:40. You can also see a time-lapse video of the sculpture’s installation here.

ORBIS - Wooden Kinetic and Lighting Sculpture

Posted by Arthur on 6 June 2014

Guido Bonelli Jr. of Innovative Electronic Solutions LLC created the ORBIS Wooden Kinetic and Lighting Sculpture for a client’s home using our custom laser cutting services. ORBIS hangs at 24″ in diameter and is 3/4″ thick. We laser-cut the parts from 1/8″ and 1/4″ baltic birch plywood, which were stained before assembly.

The separate control box and the wall unit each contain an Arduino Mega 2560 and an XBee module for wireless communication. The control box allows users to pick between two modes to control different features of the sculpture: kinetic mode allows users to adjust the rotating speed and direction of the two rings of the sculpture, and the color changing mode allows users to select various automated color patterns or control the red, green, and blue values individually to pick from 16 million colors.

Power Level Indicator for Ghostbusters Proton Gun

Posted by Arthur on 19 March 2014

Justin Chase Black (Throwing Chicken) is an artist and long-time laser cutting client who uses laser-cut parts in his prop and replica builds. Every time we ship a laser order to him, I eagerly await a new Facebook post showing off his latest project.

His work is extremely meticulous, skipping no detail in even the tiniest components. One of his more recent projects involves a tiny power level indicator on a “Proton Gun” replica from the movie Ghostbusters. Buying a power level indicator wasn’t an option; the ones he could find were made for aviation and cost over $1,000!

With a little trial and error, he was able to make them himself for a fraction of the cost by casting them out of resin, using our laser-cut parts to create the cast. A few of the design attempts did not come out well when cut from 1/8" acrylic since some of the features in the designs were much smaller than the thickness of the material (the design is only around 1/4" wide!). We cut various materials and thicknesses from 0.004" Mylar to 1/8" acrylic and a combination of thinner parts did the trick.

I’ll be sharing more awesome projects from Throwing Chicken in the future, but you can also check out his Artist page on Facebook for more updates. If you’d like to purchase a Ghostbusters Proton Gun Replica Kit, they’re sold on the Throwing Chicken Etsy shop.

If you have a cool project you’re working on and need some laser-cut parts: “Who ya gonna call?” (PO-LOLU!)
