Various ramblings – Electronics, Radio, 3D Printing & CNC
While working on a small PIC project as an addition to a larger project (a JUMA RX1 DDS LSB/CW receiver) I had the displeasure of using Microchip’s IDE MPLAB. MPLAB looks like it was designed in the mid-90’s, and while it does let you piece together code and compile it into PIC compatible hex, it’s not the most user friendly...
With the case finished, there was only one thing left to do… Jam the radio in the case and make it work! The digital dial kit and main board are secured to the case using brass stand offs (used for securing motherboards in PC cases), once cleaned up they solder rather nicely to the PCB cladding. The lid is secured...
My relatively new BK Precision multimeter got rained on, a leak in the roof on the deck soaked the table I was working on when some heavy overnight rain decided to come bucketing down. To say it was rained on is an understatement really, it must have been placed perfectly under a torrent of water that jammed more water into...
My first transceiver kit, a nice little radio with great instructions and is easy to build. I built this board over 2 nights, about 4-5 hours in total. While researching and ordering this kit I was still in the process of getting my foundation license, and not long after getting the kit in the mail I stumbled onto a small...
Some pictures of a failed project that I never got working properly and lost interest in. I removed the standard ROM on a Gameboy cartridge and soldered a bunch of wires in its place. I then wired in a PLCC socket with the intention of burning ROM’s into a PLCC EEPROM, but the games never got any further than the...
I ordered a set of DIP-PLCC adapters off eBay so I could program a chip to test a Gameboy cartridge I had modified (my EEPROM burner has a 40pin ZIF DIP socket), but there were delays in the postage. I was sick of waiting so thought I’d have a crack at making my own. I drilled out the centre of...
I picked up a Hori EX2 arcade stick to play fighting games on my Xbox 360. Great unit, though it always bugged me that it was USB and not wireless. I finally decided to investigate converting my arcade controller to wireless after having owned it for a few months. After some googling, I found out that a few people had...
A small adapter I made for programming Atmel chips, based on the ArduinoISP circuit from the Arduino website. I managed to cram the circuit onto a fairly small piece of veroboard by hiding the crystal capacitors inside the socket along with some of the links to get power to both sides of the chip being programmed The circuit performed flawlessly. After burning...
