Big boys Christmas toys.
June end of financial year sales are happening here. Unlike Christmas sales, these sales are legit. Huge discounts can be had. I've nabbed Garrick's "big Christmas present" early.
I bug Garrick pretty regularly about what toys he likes. He's pointed out the LaserX laser tag game that's in all the toy departments lately. I haven't been overly impressed. It's a nicely packaged laser gun kit, but nothing fancy, nothing new, and certainly not "new tech" or even a new idea with old tech.
However while looking around I did bump into the RECOIL branded laser game which is radically different. It's been available at retail in the U.S for the last year or so, but hasn't existed over here 'till now.
Here's some of the cool-itude
- The gun bluetooth pairs to your smartPhone.
- The phone wifi connects to a base station.
- The base station can host a game of up to 16 players.
- Game modes include a Free-for-all skirmish, Team skirmish, and Capture the flag.
- Players without a gun accessory can still play as medics and deploy utility weapons.
- The game uses your phone GPS to locate you in the battlefield. Supply crates are deployed in the virtual field which you can collect.
- Supply crates include things like armor, armor piercing rounds, landmines, more ammo, and airstrike deployments!
- The audio is great. A commando instructional voice makes the game feel great to both set-up, and play.
- The guns have a mechanical recoil motor.
- Due to the systems used, "near misses" are heard, as well as nearby gunfire on your own weapon's phone system (use headphones for premium play)
The starter kit includes a base wifi station, and x2 pistols. Additional weapons can be bought separately. These include rifles, and grenades.
The inner packaging is a bit-budget...however...
...the product feels GREAT in your hand. Good weight, feels solid. The big orange button on the hilt is the reload button.
The sights are colored plastic cylinders with a really high refractive index (maybe acrylic), so when looking down the sight they LOOK illuminated like an optical cable. The big orange button at the back is an audio-chat button. I completely forgot to test it.
The guns already have a great weight to them, but yet to be added are four AA batteries, and the users smart phone! Real guns are DECEPTIVELY heavy, so I guess all this extra weight really isn't a negative.
The phone holder is mounted with a solid m5 machine screw with a nice amount of thread engagement into a tnut embedded in the plastic. The molding of the holder and gun finger-lock into each other so the phone mount doesn't rotate about. There is an additional nut shown in this photo further towards the muzzle of the gun which is a mystery so far...
The phone clamp has a really nice set of deep spongy rubber grabbers on both sides. It worked GREAT on the three different model phones I tested. You feel that your expensive phone is completely secure.
The system was an absolute no-brainer to set up. The phone application instructions were great. The only confusion was actually playing with the usual "what do these buttons and icons do?" experiments while in a live-game. Five minutes of playing would have you as an expert-user. This is normal for the first round of any game, it's fun regardless.
So anyway...Grandpa and I went outside and had a quick test. We really did play a "test" game, not a "run around and try to win" game...but man it was REALLY fun to try a few things. We weren't ultra thorough, but got enough of a feel for it to realise it was clearly fun. Wow I wish I coulda' played with these and a bunch of guys as a kid in the yard. It's REALLY immersive. Placing landmines is sOooO fun. Sorry Tari...
The price for two more individual pistol guns is almost the price of the starter kit, and the rifles are almost the same price as the kit each. Only having two guns is dull on a battlefield...so I bought two starter kits. This gives him four guns, and a spare base-station. A pretty good deal IMO!! Can't wait for Christmas now!
Additional notes:
- The guns go into "battery saver" mode with fresh rechargeable batteries (1.2v each) instead of the intended 1.5v alkalines. In this state, the gun works fine, but the motorised recoil is disabled. Expect to buy alkalines, or make your own 5 x 1.2v battery pack.
- It has to be presumed the wifi base station suffers similarly with rechargeables. We had no problems in a brief test, but signal-strength is something you want to be operating at peak efficiency.
- The base station went through a firmware update when the 1st phone connected for the first time. This was painless and took less than 2 minutes. The app instructs you to reboot the base station when everything is done. Everything was easy.
- Playing inside resulted in many false-positive hits. Signals bounce off of everything indoors. Play outside as intended.
- Playing in outdoor GPS mode has you respawning at random locations. Often this is near instantaneous on the spot you happened to die. If you play in Indoor-mode, then respawn is controlled via a countdown. I agree with some other players video comments that this is a better respawn system, but you do lack some of the outdoor GPS functionality when playing in the indoor mode while outside.
- I tested a CHEAP ~$49 ZTE Blade L5 android phone with the Recoil gun system and it failed to work correctly. It was not able to maintain a solid wifi, gps, and bluetooth connection simultaneously while running the app live. While I doubt the entire ecosystem is particularly demanding, this phone is a BUDGET phone and would not do all-the-things. It works fine for pokemon, navigation, streaming audio, streaming video, and geocaching...but none of those use ALL the systems simultaneously. A wild guess would put any modern ~$150+ phone in the capable range. An old iPhone-5 worked fine so in that context, maybe a modern ~$89 phone will be fine. I completely forgot to test the cheap phone as a "medic" and not bluetooth'd to a gun. This might have been OK, as bluetooth was the primary failure when everything was running at once.
- The map view while playing shows the direction you're facing, however anyone that's gone geocaching knows this is dubious depending on the systems used. 1) If the system uses your compass, then the direction is PROBABLY correct. Recoil doesn't use your phone compass to my knowledge 2) If the system only uses your GPS, then it merely infers the direction you're facing via calculating a line between your current position, and previous positions. This means you MUST be moving, and movement MUST be sustained or over distances greater than 3 meters for any kind of accuracy. Spinning around leaves you no chance of correct orientation on the virtual map. You can however perform logical navigation based on known locations such as the HUB which is shown on the map.

Fridge gizmology
Back during the summer I scoured the streets for a few weeks to find a second family size fridge to accommodate the four adults that live here.
It's been working great for months 'till the last week or so, and Jana noticed the fridge isn't keeping things cool any more. The freezer works fine though. I had a feeling the fan that blows cold air from the (lower) freezer up to the fridge had stopped working...it just didn't sound the same any more.
Time for some surgical gizmology.
I'd already done some work on this fridge when I found it and discovered some dodgy handyman work at the thermostat which I had to correct. It was reasonable to suspect more garbage handyman work on this expedition down to the freezer.
Two loose screws rolling around at the bottom of the freezer drip tray is a bad start.
...and a bunch of mismatching colored wires with the worst order of electrical tape joinery...
Featuring: Uninsulated dangling wires!
Mismatching screws to mount the fan!
Jared fixed it.
All tidy and works now.
Pixel supervised for the final 20mins of the 2hr job. She was a great help.

Bedroom tablet holder
Tablets are great for watching and reading in bed. Tablets are heavier than books!! Aaarrgh my arms!!
What's this got to do with tablets or bed? Nothing!!
Cat memes forever...
Moar kitteh!!
A test arm mounted to the bed head with no tablet holder installed.
Tablet holder mounted.
The plastic knuckles are cast-off parts from a lighting component we build into a clients job at work. They're not designed for 1000mm leverage, but work great for short joints.
I need to replace this primary joint with something more substantial. I'll make something out of timber tomorrow. This failed on me during the photo-testing phase. Never mind, it was partially expected. 90% of the work is done. :)

Magna TF unique starter motor isuse.
My car suddenly started to make a terrifying loud noise. It literally sounded like a bucket of bolts being shaken around in a tin can. The car started, and drove fine...I could not pinpoint the exact source of the noise. It was just "somewhere inside the engine". Terrifying.
I bumbled into suggestions online implying a broken flexplate/driveplate (flywheel on manual transmission cars). I listened to some youtube videos online of this problem, but the sound wasn't quite right. In some obscure forum comment somewhere while looking deeper into the flexplate issue, I saw a guy mention the starter motor failing to disengage properly as a cause for some really crazy noise. While closely related, this is different to the sound you hear when you leave the key turned too long when the car has started. In that scenario, the electric motor is under power.
...so, given the complexity of dealing with an auto-trans on an East/West front wheel drive...I decided to investigate the starter motor first...
Here you can see the pinion gear doesn't really look retracted very much. It doesn't match photos of a new starter motor.
Two long bolts hold the motor to a planetary gear reduction and the pinion assembly.
The planetary gear is housed in a plastic casing. You can see this collar has broken off.
I determined that the plastic collar only serves to retain the planetary assembly as one "part" before the entire thing is assembled together with the Y-harness/spring for the pinion, and the electric motor. Once the electric motor rotor is aligned inside the planetary gear, the plastic does nothing. Everything is retained and aligned by metal parts after that. These broken parts rattling around were interfering with the intended stroke of the pinion gear.
Reassembled. Now the pinion gear looks retracted correctly!
So back in the car...everything works great! Problem solved.
