Arduino

I’ve been working on an Arduino project with the Atmel ATMega328P on a custom board using an Olimex AVR-ISP-MK2 to program through the ICSP header and kept running into an error when trying to flash a newly compiled program to the 328P. The error would come up as “avrdude: verification error, first mismatch at byte […]

I’ve been tempted to build a 3D Printer for the last couple of years. I’ve followed their development on reprap.org and on message boards and forums but never really liked the print quality and the ribbed, non-smooth appearance of the printed items. A few months ago I finally decide to try out the 3D Printing […]

I replaced the fuel pump on an 87 Honda Accord today and it wasn’t all that bad.

The fuel pump is inside the tank but you don’t need to remove the gas tank. Just disconnect the battery and open up the trunk. Remove everything over the spare tire and near the back seat on the left you’ll see a metal disc sealed to the
bottom of the trunk. Remove the metal disk with a screwdriver and you’ll see the fuel pump assembly. Disconnect the electrical cable and the fuel line (some fuel may run out so no open flames, furnaces, stoves, water heaters or cigs near this.) Open the gas cap to relieve any pressure then remove the 6 bolts on top of the assembly and extract the fuel pump.

The replacement fuel pump has instructions but you must ALSO get a new filter for the new pump. The OEM FILTER WONT FIT and a new one wasn’t included! This cost me an extra trip to auto zone.

Replace the fuel pump according to the instructions and reinstall. Overall cost was about $70.

On a 1-10 scale of difficulty I’d rate this a 5 just because of the fire risk of the open fuel tank AND people’s lack of common sense around flammable materials.

I just did my first flight with my Multicopter FPV setup and it was AWESOME! I’ve flown planes and gliders via FPV before, but one of the main reasons for building my Multicopter was to do FPV. My final goal is to attach a stabilized DSLR onto my multicopter rig and shoot some high quality […]

I have wanted to get into multicopter building and flying for a few years now but this year I finally took the dive and got into it pretty quickly. I did a lot of reading and shopping for which flight controller to purchase and while I would like to experiment with the open source software […]
