& Welcome: we provide open source designs for biomass
briquetting applications along with chime design and build. Designs include parts list, notes,
drawings and assembly instructions. Below are some recent
articles covering a range of topics.
sounding set of wind chimes can be built for about $15 to $40
depending on the chime set size you select. Choose from four
height selections ranging from 36 to 75 inches (900-1900 mm).
Add your creative touch by altering the material and style used
for the top support disk, striker and wind sail.
This small press is
suggested for single-family use, classroom demonstrations,
or a small village. Best used where a small footprint and easy to build press using hand
tools are required. There are two versions, Brace or Notch.
This is about Choices. Briquetting for any operation requires a biomass
mold, whether it’s a small village, single family, or classroom operation.
You have choices and there are no wrong or right, best or worst, good or
bad molds for making biomass briquettes.
A variety of molds will
work equally well and one type may be best suited for you
depending on the availability of construction materials, tools, cost, skill level, and briquetting requirements. This
document provides choices to consider when selecting a
biomass mold design.
Molds for shaping biomass into round, square, sticks, cubes
& chunks. Drilled, slotted, and split PVC molds along
with slotted wood as an alternate to PVC. Two caulking gun presses, split plunger pistons and more. Other DIY biomass designs Here

How time was decided in the Greater Cincinnati area before radio
signals, telegraphy, or other electronic methods. Preserving our
global heritage for signaling time, prior to modern electronic
methods, were time balls, time guns and time flaps that
synchronized with the local astronomical observatory. First
dropped in 1829 at Portsmouth, England, they remain today an

The traditional configuration of facing the headstone
along an east–west axis and positioning the body with the head pointing
west, thereby allowing the feet to see the rising sun, was not followed
with this pattern; instead, the wheel pattern was used, but why?

Dodge’s Institute of Telegraphy (DIT) began in December 1873 and
largest school of its kind in the Western Hemisphere. The institute
wireless telegraphy and courses in radio technology were added to the
In 1944, DIT was renamed Valparaiso Technical Institute (Valpo
Tech or VTI). Rated among the top 10 such educational organizations in
the world, Valpo Tech became the oldest electronic institute in the
country. The school celebrated its final graduation on May 25, 1990, and
closed its doors after the January 1991 graduation, sponsored by the
Valpo Tech Alumni Association.
As a quarter century has passed since the last VTI commencement
ceremony, I present this article in honor of all DIT and VTI graduates
on this Memorial Day, May 25, 2015.

Our scholarly work breaks new ground on an event that was of
tremendous importance to the world: the testing of the first
successful reaping machine, which revolutionized agriculture
globally in the nineteenth century and started farming down
the path toward industrialization. That test,
with its far-reaching consequences, took place near Mt.
Healthy, Ohio, in 1835. Even though books and articles from
the 1800s and early 1900s noted the achievement, it has been
largely overlooked in our time, and it has never been fully
researched and described. Bob and I made it our mission to
investigate the matter thoroughly. Over the past year, we
discovered many surprising facts that had been forgotten or
that had never been brought to light.

Inventor of the Reaper, Obed Hussey, Ohio
Historical Marker, Dedicated September 9, 2017
On the 12th of December (2014), Leland
Hite and Robert T. Rhode, acting on behalf of the Mt.
Healthy Historical Society, recovered the last remaining
component of the first cable suspension bridge built in
Ohio. The 167-year-old iron tripod was one of four that had supported the
cables of the 42′ bridge crossing the West Branch of Mill
Creek near Mt. Healthy. Built in 1847, the footbridge on the
Lane family farm was the brainchild of William Lane, brother
of Clark Lane, the noted industrialist whose company of
Owens, Lane & Dyer manufactured steam engines and sawmills
in Hamilton, Ohio. The ingenious bridge was one of the first
suspension bridges in the United States.

Said by Ersal Kindel: "A Sharp
Tool Is A Safe Tool, has been said many times and I say it again.
Not only that but there is joy in using a sharp tool. There is a lot of
satisfaction in making smooth clean cuts in a piece of wood, but---this
is nearly impossible if the cutting edge is not sharp. So, let's see how
we can get and hold a sharp edge.
I'll show you one way −
the way I do it."
