Took a brief break from work this afternoon to see if the hummingbirds would take to a feeder, sans the usual red dye nectar. Seems they are thirsty enough to try the new homebrew.
The ruby-throated hummingbird (Archilochus colubris) is a species of hummingbird that generally spends the winter in Central America, Mexico, and Florida, and migrates to Eastern North America for the summer to breed. It is by far the most common hummingbird seen east of the Mississippi River in North America.
Friday 12th April ... my Homebrew, ('Hearthstone' Stout), is ready for drinking. 😋
Another mobile 'phone image.
I retrieved this piece from some 'junk' that was being thrown out. I think it is an early homemade variable inductor. The two end pieces are hinged on small nails. At one time either side could be made to stay at any distance from the central coil. Has anyone else seen one of these? It reminds me of the Crosley 'book condensers'.

Field testing my first kitbash camera, the Bessabron SWC. The body/film transport is from a 1930s Bessa 66 with a re-housed Bronica 645 40mm f4 on the front. The idea was to recreate the general specs of a Hasselblad SWC from old parts. I think I've finally eliminated any remaining light leaks Still tweaking things but very happy overall
Camera: Bessabron SWC (homemade)
Film: Tri-X
I built this portable 2-meter (144 MHz) antenna from a plan in Vertical Antenna Classics, published by the American Radio Relay League (ARRL). This simplest way to describe it is as a telescoping 5/8-wavelength vertical antenna above a ground plane of four folding telescoping quarter-wave radial whips.
The heart of the antenna is a BNC female-to-female chassis-mount connector, to which I mounted a steel washer with four equally spaced holes. One of the quarter-wave telescoping antennas is mounted on each hole. I used 19.3" six-section whips that I purchased on eBay.
For the vertical, I used a Diamond RH-205 5/8-wave base-loaded telescoping whip, which is mounted to the upper BNC connector. A 3-foot length of coax cable with male BNC connectors at each end is attached to the lower connector.
I have not yet tested the antenna operationally; the author claims a theoretical 8 dB over the stock rubber duck antenna, though.
This was a great starter project, as the most difficult part was drilling the holes in the washer. It is very light and breaks down into small, easily-packed pieces. My hope is to extend my range during "Summits-On-The-Air" (SOTA) activations.
The above photo shows my little Yaesu VX-6R handheld connected to the antenna.
Make an easy to build portable softbox
- cut a backing frame from a 1/2 gallon plastic milk jug
- shape the plastic to fit the rear of your flash, like a bounce card, narrow at the bottom and more flared out at the top
- line the front of the plastic with a reflective material. I used the shiny mylar material from a package of Nabisco oatmeal cookies. I attached the mylar using double-sided tape.
- tape down the edges of the mylar to the plastic using gaffers tape
- Attach the reflector to flash using rubber bands
- make a "flip down" diffuser using simple tissue paper or other diffusing material
The flash and portable softbox can be used on-camera or off-camera, One Light Strobist style.

This is the third test of the original 1 liter of Hodes' monobath. Hodes' times were under or well under 5 minutes at 80 to 93 degrees F. I misinterpreted the original negatives thinking I had way over developed them and possibly the emulsion speed was slow. The second test at 3 minutes was completely washed out and thin. I realized that what I thought was 68 degrees F room temp was 60 degrees - a variation of at least 20 degrees. This third attempt, with Kodak 2238 film shot at ISO 16, with now used solution, was done for 6 minutes with constant agitation at 95 degrees. The results are as good as I would get from a conventional developer. Perhaps better in some ways.
Hodes' monobath is a low gamma developer with a cysteine fixer. The fix bath was the reason I kept working with this, even though I thought it was becoming a wasted effort. It was not

Above is a closeup of the heart of the antenna. The only liberty I took with the original plan was to add a 90-degree BNC female-to-male adapter to the bottom connector; the original plan has the coax plugging straight up into the bottom connector. I'm not yet sure if this addition will affect the efficiency of the antenna.
This is a cheap home brew SD card adapter for the Arduino. I will be using this with my Arduino Uno to make a SD floppy disk adapter for my 8bit Atari computers. See www.whizzosoftware.com/sio2arduino for more info on this project.
I got the design from this site : nathan.chantrell.net/20111128/diy-micro-sd-shield-for-ard...
