This blog will keep to a simple theme of my tinkering with electronic and computer related toys, gadgets, projects and the like. I do hope from time to time there is something for someone to find when they are exploring these things for themselves. From an early age, I was always attracted to electronic gadgets an I continue to enjoy myself with my hobby. Unfortunately with a busy life, time becomes short an I can not indulge myself like in the past.
The AA7B is an antenna amplifier which will amplify radio frequency signals (HF, VHF, UHF). I'll use the AA7B with the SR2C in a future post for demonstration. The AA7B is connected by coaxial cable to the receiver. In addition, the AA7B can be powered by a 9V internal battery of external power supply. The AA7B is for boosting reception only; transmitting RF into the AA7B will damage the unit.
The Ramsey's SR2C is a single-conversion superheterodyne receiver designed for listening to AM broadcasting stations in the range of 4-19.5 MHZ. The SR2C does not come with an antenna or external speaker. In a future post, I will demonstrate the SRC2.
This is Kit 27 from Kitsrus a 1 Watt Mono Power (audio) Amplifier featuring Philips integrated circuit TDA 7052. I built this kit to modify a shortwave radio that will be featured in a future post the Ramsey's SR2C. This amplifier uses a 6-12 volt direct current power supply to drive up to a 8 ohms speaker. In the picture, I have a 8 ohm speaker, a 12VDC battery pack, and a mono plug attached; these items are add-ons and do not come with the kit.
I decided to sell my PanaVise 333 Rapid Assembly Circuit Board holder for the PanaVise 350 Multi-purpose unite. The 350 unite offers Ribbed, neoprene jaw pads and a self-centering 9-inch jaws. I did this because the 333 was too big for smaller PCB and did not allow me to work on the connections that were located at the edge of my PCB; more over, I could change out the vise with the 315 Circuit Board Holder (my preferred head for working a PCB). The 315 comes with a standard 12-inch cross bar, but, like me, one can buy bigger bars. I bought a 22 and 30-inch crossbar, and extra arms if I have two PCB on the bar at once. Lastly, I added the PanaVise 371 Solder Station, which is, a soldering iron holder, controlled solder wire feeder, and two sponges. The 371 is mounted with screws to the base of the vise. PanaVise for me is the best tool on the market for electronic hobbyist but PanaVise offers a wide selection of Vises and accessory's. In closing, I like to say that PanaVise offers the best customer service I have experienced. Thank you Cheri because you answered every question I had when I was putting together my vise.

This is an Infrared Spotlight on a 6x6 printed circuit board using six 100 ohm resistors and 36 IR light emitting diodes. The Spotlight requires a 12 VDC power-supply. In the pictures and video, the Spotlight did not illuminate or allow my camera to work in the dark, in other words, see in the dark . The Infrared Spotlight did seem to compliment my night owl scope with out using the scopes built-in IR. When I get the 12 volt battery pack, I can do a better assessment out of my work shop since I am tethered to my power supply currently. Some possible uses is as an IR-beckon, a complement to an IR-enabled device, or, possibly IR for a robot, but with the addition of IR light detectors.
