i spent most of saturday in the valley and what's a trip to the valley without a visit to Fry's in Burbank?? the theme of the store is alien/monster attack.

The FlashTron is a small light synth that makes a large range of electronic noises. It plays a little bit like a theremin, but with light as the main control.
Another Favourite of mine is the Yashica T4D. Superbly sharp lens and considered the poor mans Contax T2. I've owned both and they are impressive performers. This is my last shot of it before I put it upfor sale. Selling my film compacts as i rarely shoot film nowadays. Now sold.
Noong 13 Hunyo 1946, itinatag ng Amerikanong inhinyero na si James Lindenberg ang Bolinao Electronics Corporation (BEC), isang kompanya na gumagawa at bumubuo ng mga kasangkapan para sa radio transmission. Noon taong 1949, lumapit si Lindenberg sa Kongreso ng Filipinas upang hingin ang pahintulot na magtatag at magpatakbo ng isang himpilan ng telebisyon. At noong 14 Hunyo 1950, naaprobahan ang kaniyang kahilingan sa pamamagitan ng Republic Act No. 511 at 512, na nakasaad ang mga responsabilidad sa publiko ng isang himpilan ng telebisyon, tulad ng pagpapalaganap ng makabuluhang kaalaman lalo na sa mahahalagang isyung pampubliko. Ngunit dahil sa kakulangan sa materyales at mahigpit na patakaran sa pag-aangkat ng mga dayuhang produkto, itinuon na lamang ng BEC ang atensiyon sa pagsasahimpapawid sa radyo.
Taóng 1952 nang binili ni Antonio Quirino, na naghahangad ding magtatag ng isang himpilan ng telebisyon, ang malaking porsiyento ng BEC at pinalitan ang pangalan nitó bilang Alto Broadcasting System (ABS). Si Lindenberg ang naging punòng tagapamahala ng himpilan. Noong 23 Oktubre 1953, ang DZAQ-TV 3 sa ilalim ng pamunuan ng ABS ay unang sumahimpapawid at ipinakilála bilang ang kauna-unahang himpilan ng telebisyon sa bansa. Kayâ namang itinuturing ang BEC bilang pinagugatan ng television broadcasting sa Filipinas at si Lindenberg bilang ama ng Telebisyong Filipino.
Noong 1958, ang ABS ay nabili nina Eugenio Lopez, Sr. at ang noo’y pangalawang pangulo na si Fernando Lopez na siyáng may-ari ng Chronicle Broadcasting Network (CBN), isang radio network). Paglipas ng ilang taon, pormal na pinagsanib ang dalawang korporasyon at tinawag na ABS-CBN Broadcasting Corporation. Sa kasalukuyan, ang ABS-CBN ang isa sa mga kilalá at nangungunang kompanya sa larangan ng midya sa bansa. (MJ) ed VSA
Drones are one of the coolest gadgets out there right now, and there are so many different reasons you'd want to operate one.
A lot of the testing equipment may seem old, but it's likely rather new. The again most of the fleet is, on average, 27 years old.

Picked this up in an antiques market in Buenos Aires; it's super light but not that small and leaks a bit of light.

Here's the circuit for the Black Box Lightshow. I'm pretty sure it's right. And now, an explanation:
The LED array is shown here as individual diodes, though I used six 5x7 LED arrays, each one is 2" tall. They are arranged as 14 rows and 15 columns. The left channel is 8 columns and the right channel is 7 columns. The extra column from the left channel is the center column and gives nice symmetry. Not shown here is that on the right channel, the first column (pin 1) is not used so that the other columns are equal.
The LM3914 is a Dot/Bar Display Driver. It does all the heavy lifting of converting the audio signal into a series of bars - these are typically used as digital meters. The potentiometer sets the sensitivity of the display. Since the rows are multiplexed (see below), each column is only driving one LED at a time. I only show the left channel here, the right channel is identical, and they share the level setting potentiometer.
The right portion of the diagram is a 555 clock, a 7493 4-bit counter and a 74154 4-to-16 line decoder/demultiplexer. This is the "sweep" part of the display that cycles through each row of LEDs. The potentiometer at the top controls the sweep speed. The net result is that the 74154 is cycling through the pins/rows, grounding each in succession. Note that I only have 14 rows, but it is counting to 16 each time. No big deal, it doesn't affect the perceived output at all.
The N2907 transistors are there to provide enough power for all the LEDs. Potentially, all 15 LEDs in a row can be lit up at once, so the transistors make sure there is enough juice.
Unfortunately, I lost the original plans during a garage cleaning after I built the electronics (the box took another few months before I got around to it). I opened it up and reverse engineered my own work. I won't guarantee it, but it sure looks right to me. The one weird thing I found is that I don't have power going to pin 8 of the 555 (as shown here), but it works fine - go figure. Also, I'm not 100% sure I got the polarity of the LEDs right, sorry about that. I would recommend testing that out first.
Please post if you build this and let me know! Also, happy to answer questions along the way.

Prototype 4x4 matrix mixer. Inputs on the left, outputs on the right. DC coupled so it will work with audio and control voltages. Each knob effectively controls the signal level from an input bus to an output.
This board offers 4 channels of opto isolation. Its awesome for protecting circuits and stuff.
