An eastbound on the B&OCT hits Conrail's ex PRR FT. Wayne Line at Clarke Jct. in Gary, Indiana in the Falll of 1986. Conrail was in the process of single tracking the old Pennsy, and new signals bagged off are seen to the right as well as behing the semaphore. The semaphore was a Wabash train order signal. Eastbound Wabash trains left trackage rights just behind where I am standing and entered the 4th District rails, so grabbed orders at Clarke Jct. The tower was to the left of the semaphore.
For dinner tonight, since it was so hot & steamy, I whipped up a classic omelette recipe found in a vintage French cookbook. They were delicious, but required the use of many, many onions that had to be caramelized first...my eyes are still stinging, despite my having much earlier tossed said onions into the fridge to cut down on the pain! (FWIW, this *does* help, but needs to be done at least an hour ahead of time.) Anyhow, here's a peek into one of the kitchen linen drawers. My eyes can't take looking at a whole lot just yet! ;)
I will beat the fucking system with my egg-beater.

Looks a bit odd, sited away from the fence like that … but the fence is electrified - NOW it makes sense! 😂
Sheep are run into a large contained catchment area, then run through a narrowed alleyway, where they can be dosed with wormer, or whatever. Next is a crate for weighing fit lambs which can then be penned separately or released with the ewes, as per requirements.
A handling system like this reduces stress on the sheep (and stress on the handler!).
I've used similar many times over the years and with weighing apparatus, a cradle for turning sheep over to trim their feet (doesn't half save the shepherd's back!) plus gates in the feeder tunnels allows the sheep to be drenched (given wormers etc) foot-bathed and so on, a handling system really does reduce stress on both sheep and handler! In fact, I've seen sheep walk happily into a handling system at first sight of the dog, with no need for coercion of any kind!
I've written about this before. In practice it seems some lens/body combinations can be a little laggy at stopping down the aperture, but it was a noble concept. I notice that eBay sellers often do not realize what they're selling is a TX lens; and so there can be bargains if the mount type is unclear or some oddball one like Miranda.
Remote Node which uses a old Nokia phone charger to break down the
120V power source to 5V then a 3V regulator for the Xbee module. Not
much else to this side besides two blue LEDs. I had a much stronger
signal use the Xbee modules with small whip antenna as opposed to the
chip antenna.

Going from my Nikko integrated, to a new Kenwood system, you can see the system progress. However I downgraded my speakers it seems! I am also showing off my new CD player, a Fisher Studio Standard. LOL The big black box is a lightshow switcher and chaser system, with color organ of course!

Finally got a chance to work on the shark today and got her on the road for the first time in about 7 months. Threw on these M-System wheels to see how I like them ... not bad, but the 4x4 status is killing the look, not to mention they're in desperate need of freshening up. Suspension up next!
Sometimes I feel like building digitally makes me lazy, and the physical stuff was more challenging.
Then I port something into LDD and that pretty much gets affirmed.
Nike-Hercules Missile, designation MIM-14 (initially SAM-N-25), was a solid fuel propelled surface-to-air missile, used by US and NATO armed forces for high- and medium-altitude air defense. It could also be employed in a surface-to-surface role.The Nike-Hercules system, a follow-up to the Nike-Ajax missile, was developed during the Cold War to destroy enemy bombers and enemy bomber formations, as well as serve as an anti-ballistic missile system. Western Electric, Bell Laboratories, and Douglas Aircraft Company were chief contractors for the system. Nuclear-armed Nike Hercules missiles were deployed in the United States, Greece, Italy, and Turkey, and with Belgian, Dutch, and U.S. forces in West Germany. Conventionally-armed Nike Hercules missiles also served in the United States, Germany, Denmark, Japan, Norway, and Taiwan.The first deployments in Europe began in 1959 and the last nuclear-armed Nike Hercules missiles in Europe were deactivated in 1988. The Nike-Hercules missile systems sold to Japan (Nike J) were subsequently upgraded the internal guidance systems by replacing the original vacuum tube systems with transistorized ones.The guidance and control area (Integrated Fire Control, IFC) was located a distance (about 1 mile) from the area from where the missile was launched (Launching Area, LA). The IFC had an acquisition radar to detect (enemy) aircraft. After detecting and identifying a hostile aircraft this aircraft was followed or tracked in elevation, azimuth and range by a Target Tracking Radar (TTR). An analog (later digital) computer computed a point in the sky where the missile and target should meet (intercept point). After the missile was launched by the Battery Control Officer (BCO) a Missile Tracking Radar (MTR) followed the missile and the computer constantly updated the intercept point even if the hostile aircraft performed evasive actions. Steering corrections were sent to the missile by the MTR. When the missile neared the intercept point a command signal was sent to the missile to explode. To measure the range to the target under jamming conditions the IFC also was equipped with a Target Ranging Radar (TRR).
Il MIM-14 Nike Hercules è un missile di fabbricazione statunitense per la difesa antiaerea. Prodotto a partire dagli anni cinquanta fu in dotazione a molte forze armate che aderivano alla NATO.
Il missile MIM-14 Nike Hercules, fece il suo ingresso nel 1958. Pesava circa 5 tonnellate, con 4 motori ausiliari molto simile al precedente sistema missilistico Ajax.Venne utilizzato anche tra le schiere dell'Aeronautica Militare Italiana, che equipaggiò 3 stormi, complessivamente 96 lanciatori, con il suddetto sistema terra-aria.Al giorno d'oggi i MIM-14, sono stati tutti radiati con cerimonia ufficiale.Originariamente il missile venne chiamato SAM-A-25 Nike Hercules, ma poi nelle varie vicissitudini che ebbero le designazioni americane di quel decennio, venne ribattezzato M6, e infine MIM-14. Nel 1958 esso entrò in servizio, rimpiazzando l'Ajax per le basi a difesa di New York, Chicago e Washington D.C..Il nuovo sistema missilistico era quindi stato progettato per essere un'arma formidabile. Esso aveva prestazioni per l'epoca eccezionali, soprattutto in termini di gittata e di quota, tanto che i bombardieri pilotati stratosferici, anche se supersonici, vennero messi in dubbio, e dopo l'avvento di questo sistema non avrebbero più avuto la stessa importanza di prima.La sua struttura, molto caratteristica, era aguzza e possente al tempo stesso, con un insieme di caratteristiche che lo rendevano unico tra i pur numerosi missili antiaerei dell'epoca. Esso era bistadio: il primo aveva ben 4 motori a razzo con propellenti solidi, riuniti in un complesso chiamato M42, studiato per ridurre la lunghezza del missile a valori accettabili, e realizzato con i motori di accelerazione (booster) M5E1. Esso era dotato anche di 4 ali cruciformi per la stabilizzazione. Questo complesso pesava da solo 2345 kg e dava quasi 80.000 kg di spinta per 3,4 secondi.Una volta finita la spinta, veniva sganciato per non appesantire inutilmente il corpo missile vero e proprio, di diametro minore, e che era dotato di una struttura a 'pallottola allungata', con 4 alette anteriori fisse, 4 grandi alette triangolari posteriori per la stabilità del volo ma anche con elevoni per il controllo della direzione e quota, sistemati nella parte finale.Anche la guida del missile era su comando radio. Non appare infatti che esso avesse nessun sistema di bordo per l'acquisizione semiautonoma o autonoma del bersaglio di tipo radar o IR, ma le alette anteriori erano utilizzate come antenne per ricevere i comandi radio da terra ,mentre esisteva un trasponder per dare la posizione del missile alla stazione radar.

A 'short' project; convert a lipo charger into an arduino controlled system with a nicer display and 16bit a/d converters for voltage and current monitoring. Lots of useful features and open source, when its done.
The old school (literally; its probably over 40 years old, that 1k carbon) resistor thing is there to set the module's i2c address. They use an interesting way of using 1 wire to select from more than just 2 i2c addrs. you can tie the line to high, low or a SIGNAL line on the chip and it will know which one, even if the data changes (being on a signal line). Weird! But pretty cool idea. So, using a junker resistor, I selected addr 0x48. (Its usually a good idea to tie config lines to high or low thru a resistor instead of a direct connection. On some lines, they may want to output a level (for a short while) and if you hard-tied it to Vcc or gnd, that could be a 'fight').
This A/D module has 4 inputs (a0..a3) and you can use them in single ended mode or as pairs of differential (which is how I'm using it, here). In diff mode, I don't have to be ground-referenced; I can measure the battery voltage 'directly' from its + and - terminals. Same with current, I can use a 0.1ohm resistor as my sensor and put my diff-pair of wires across that resistor to measure 10x the actual current value, in Amps. The current measurement has to be differential since you are not doing a ground-referenced measurement at all!
The a/d module is easy to find, its $10 on amazon/etc.
The charger engine, itself, is an adafruit micro lipo board. The important part that makes this all work is the fact that the charger 'speed' (or Amps setting) is set by a single resistor and it works fine if you use a digital pot (spi or i2c; mine is spi since that's what I had on-hand) and a cpu to control it. A lookup table maps the current/amp value to the 0..255 pot value I have to set in software. With a 10k pot, you can go from less than 100mA to over 700mA of charge range, enough to cover almost all of my RC hobby batteries ;)
The two copters there are some of the test subjects ;) Small blue guy is a cheerson cx10 with built-in battery. The gold guy is a JJRC h20 hexacopter, with battery bay and external 150mA batteries. The cheerson is very small and cute, but not a very exciting flier. The h20, otoh, is quite a good flier, with good speed and fast control. Both are $20 or less (which I find amazing in itself).
