DF06 Aposematic (Friends style diesel shunter)

Remote Control for Mindstorms Robot outside of home.
dr_spock replied to jabz10's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Maybe a collar with an active radio like keyless entry system for cars would be simpler. If the system detects the collar nearby it can send a command to the mindstorm to open the cat door. When the collar is not detected, a close door command can be sent. Infrared sensors could be used to determine if it is safe to close the door. Or activate the water gun if they detect something and collar radio signal is not present. -

Nice. Dark pink and neon yellow works really well. Some times industries paint some of their equipment pink in support of breast cancer. -
It could be that the PU connectors have an active patent and may need licensing agreement with the TLG. Also PF is no longer produced or sold by LEGO so there is an easy niche market for 3rd parties to fill. I don't use 3rd party. Much cheaper and simpler to 3d print them and reuse old CAT5 wires. It is kind of fun learning to make your own stuff. PF train motors were cheaper than PU train motors and PU remote doesn't need line of sight to control like PF IR.

Why do American Lego sets have the number of pieces on the box but other countries don't?
dr_spock replied to MrZ's topic in General LEGO Discussion
Canadian 1980s sets have number of pieces listed on the bottom right hand corner. -
You could also try to glue shims under your baseplates so that they matches up to the height of the regular plates.

LEGO light bricks are bright enough for low light conditions. Those little button cells won't last very long if left constantly on. The batteries can go bad and leak from sitting in storage too. Measure the current draw of your lighting system, determine how long you want the light to last, and size your power source's amp hours according.

9V Battery Adapter for Lego Powered Up/Control+ Hub
dr_spock replied to 2GodBDGlory's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Soldering is not required if prewired 9V battery connectors and 3rd party PF connectors are used. Put the wire in the correct pin and press hard. Those components can be found on AliExpress.com. Several could be made for the price of a Green geckos If the 9V connector comes with pre-stripped wires, they can be cut off before putting in the PF connector to avoid short circuits. -

9V Battery Adapter for Lego Powered Up/Control+ Hub
dr_spock replied to 2GodBDGlory's topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Nice work. I think those 9V Li-Ion batteries should last enough for a truck trial run. I was puling at most 1.24 Amps on my WIP truck with 2L motors using an EBL battery. Those 9V Li-Ion batteries are not so expensive that you can't have a couple to swap out. Beats having to recharge in the woods. -
Cute. Looks like it could run year round at a tourist railroad in New Hampshire.

Sounds like the lithium cells may have dropped below safe voltage to charge. Is there warranty?

Merry Christmas!

Nice. Do they allow for traction tires?
