AE1S Amateur Radio Blog: Installing lights on Traxxas E-Revo VXL
http://blog.kotarak.net/2013/07/installing-lights-on-traxxas-e-revo-vxl.html
Monday, July 15, 2013. Installing lights on Traxxas E-Revo VXL. My son really wanted his RC car to have lights "just like on the real cars". The Spektrum SR3300T receiver is a 3 channel receiver and the AUX channel can be used to control lights - so why not? Turning the head and tail lights by flipping the AUX switch on the remote control was an extra feature, I thought would be pretty cool. Parts used: rc-lights.com kits - RCL5004E, RCL5090 and miscellaneous connectors, wires, resistors. I made two elon...
AE1S Amateur Radio Blog: April 2015
http://blog.kotarak.net/2015_04_01_archive.html
Tuesday, April 28, 2015. Canon EF-S vs. EF Lens shaprness when shooting with APS-C. All shots were taken with Canon EOS 70D set on manual mode, ISO 500, fully open aperture. The idea was to compare the details in the image thus the lens sharpness. All images are a 100% crop - 1200 x 1000 px from the original pictures. I chose a subject with a lot of dust particles and imperfections rendering small details. EF-S 18-55mm @ 55 mm. EF 28-105mm @55 mm. Canon EF-S 18-55mm @ 26mm. Canon EF 28-105mm @28mm. Local...
AE1S Amateur Radio Blog: Align 450 DFC - Blade grip control link mod
http://blog.kotarak.net/2013/06/align-450-dfc-blade-grip-control-link.html
Thursday, June 6, 2013. Align 450 DFC - Blade grip control link mod. One disadvantage of the DFC (Direct Flight Control) Rotor Head is that it puts the blade grip control links under a lot of strain and they eventually can fail causing a crash. Align tried to solve the issue by changing the design of these links and supposedly making them stronger . The main issue with this design as part of a DFC rotor head is that it relies on a very stiff head dampening in order to minimize the axial movement of the f...
AE1S Amateur Radio Blog: Pebble Steel - the best digital watch I could wish for
http://blog.kotarak.net/2014/08/pebble-steel-best-digital-watch-i-could.html
Monday, August 11, 2014. Pebble Steel - the best digital watch I could wish for. They have some pretty cool and unusual designs. There is another problem I had - one looks at the watch a number of times a day, every day, every month and if you are like me - I'd get tired of the same watch after a month or two and would like to see something else on the display but then it means owning and maintaining a bunch of these watches and who has time and money for that. Even if you don't care about the Smart Watc...
AE1S Amateur Radio Blog: The Intelligent Telescope Dew Shield - iDewShield
http://blog.kotarak.net/2014/01/the-intelligent-telescope-dew-shield.html
Thursday, January 23, 2014. The Intelligent Telescope Dew Shield - iDewShield. Dew not only spoils the observation sessions but also dissolves contaminants in the air thus causing deterioration of the anti-reflective coatings. No matter how you slice it - it is a bad thing. So, here is the idea I have and it is what I have been working on lately - an Intelligent Dew Shield - iDewShield (again, the dreaded Apple Computers naming convention) based on the Arduino Controller. Andrey E. Stoev. For the amplifi...

K2ZA - Explorations in Amateur Radio. Amateur Radio, Electronics and Miscellany. Sunday, May 9, 2010. FT-817 Tip - Spectrum Scope. The Spectrum Scope Monitor (SSM) is a very handy feature of the FT-817 allowing you to monitor a quiet band and see when signals pop up outside the receiver passband. There are a couple of things not explained in the manual that make SSM more valuable as an operating aid. If you found this tip useful, please leave a comment. Links to this post.

K2ZA - Explorations in Amateur Radio: February 2011
http://k2za.blogspot.com/2011_02_01_archive.html
K2ZA - Explorations in Amateur Radio. Amateur Radio, Electronics and Miscellany. Saturday, February 19, 2011. A wonderful afternoon in the SolderSmoke shack. As my father was gifted with "the Knack" and a fellow devotee of the fire bottle, and Bill had mentioned on a podcast episode that he regretted letting the DX-100 of his youth slip away, it seemed right that my Dad's transmitter should find a new home in Northern Virginia. Fire Bottle = Thermionic Valve = Vacuum Tube. Links to this post. Michael J&#...
LZ4ZD - Любителско радио и фотография: ISD2560 Voice Keyer
http://lz4zd.blogspot.com/2008/11/isd2560-voice-keyer.html
LZ4ZD - Любителско радио и фотография. Неделя, 16 ноември 2008 г. По време на SSB контести се налага много викане на CQ. Тази част от контеста може много лесно да се автоматизира с използването на voice keyer на базата на ISD2560. Това е чип за запис на глас до 60с. и честота на дискретизация 8kHz - напълно достатъчно като качество. Първоначалния проект беше започнат още преди една година, малко преди LZDX 2007 контест. Тогава захванах да повтарям проекта на Serge VE2HLS. Проекта се намира тук. Наложи се...

http://lz4zd.blogspot.com/2007_12_01_archive.html
LZ4ZD - Любителско радио и фотография. Неделя, 9 декември 2007 г. От LongWire към DeltaLoop. Първите проби на 80 метра са положителни, но все още искат време и повечко QSOта. Събота, 1 декември 2007 г. Почти две седмици вече се струпа много служебна и лична работа. Нямах никакво време да се похваля с новото радио. Все още нямам време да направя някое QSO, надявам се този уикенд и това да стане. Направи ми много добро впечатление съвместимоста по изводи със стария ми Kenwood TS-430S.

LZ4ZD - Любителско радио и фотография. Събота, 10 ноември 2007 г. Навън вече вали първия сняг, а на мен още ми е есенно. Миналия уикенд се разходих да поснимам малко есенна красота и реших, че е крайно време да наблегна и на фотографията в този блог. Стига толкова думи, хайде да погледаме снимки :).

LZ4ZD - Любителско радио и фотография. Неделя, 25 май 2008 г. RSSI изход за MC3361. Наложи ми се да изкарам RSSI(Radio Strenght Signal Indicator) изход, или с други по-лесни думи "S-метър" изход. Приемника на мобилната станция ( Midland 70-1336. E направен с MC3361BP. Първото решение което пробвах беше AD8307. Беше достатъчно ясна и без описание. TK14565 нямам, нямам и намерение да ходя да го търся. Под ръка имах само MC13135P. Използвам съвсем малка част от MC13135 - само ограничителя (Limiter). Сиг...

Tuesday, November 3, 2015. When Lightning Strkes . I started wondering how the lightning discharge came into the house? Everything in my lab is grounded - I have a huge copper ground bus, attached with an 8 inch wide solid copper strap to the ground rods and every single piece of equipment in the Ham shack is attached to this bus with solid copper straps. The controller was grounded via the ground post on the back of the chassis to the main ground bus. It is now obvious that the hit came in thru the cont...
