I recently built myself a backup NAS drive using Windows-7 professional as the OS. The power profile of this system was simple. Everyday wakeup at 3:00AM and sync up between the shared-drive and backup-drive. I use the task-scheduler to set…
For one of my projects i had to use the LTC3526 Boost Switching regulator chip from Linear. It is a great chip. One downside being an extremely small 2mmx2mm DFN package I never soldered a chip with this fine pitch.…
I recently finished building a NAS box to suit my media storage needs. Especially photos taken by my SLR and our iphones. Our backup had been mostly adhoc: Using an external USB disk to store data. While the disk is…
I recently rewound a Hextronik 1300Kv brushless motor (HXM2730-1300), also called “blue wonder”. I rewound it to see if i can make it better. Better thrust, cleaner windings and lower current consumption. Some specs related to the motor insides… Number…
For my latest project i wanted to use the famous GRBL firmware that loads into an arduino and helps drive steppers with G-code as input. I had an Arduino-Uno that i wanted to use. Now the arduino IDE can be…
I had a lot of old style passenger carriers in my HO collection and i wanted to add LED lighting to them. So i quickly threw in a Schottky diode bridge, followed by a 470uf capacitor to convert the pulsing…
I have a turnigy9x radio that came with a 2.4Ghz module. However i also had some DSM2 receivers (Orange rx) that i wanted to use. I came across lots of posts that describe the process of adding a DSM2 module…
Recently the USBASP programmer has become a hot favorite to program AVR chips. It is small, inexpensive and works great with avrdude. I was recently working with an RC brushless speed controller (ESC) and wanted to read the fuse values…
Having a fine gauge wire is really important with HO scale and finer gauge model railways. These locomotives are small and you really don’t want the wires to be the show stoppers to finishing your models. In the past i…
This documents my re-motoring and DCC mod of my Roco BR118 loco. This was an older loco that came with a great Roco motor. However there were 2 issues. 1: The motor’s stall current was about 1amp 2: The loco…
