@Sean0Did a 26 mile cycle ride from home to a campsite. Now enjoying a drink
@MahakKumawat-U04ER6F116H0Yo, it's like Day 4 or something and the person I was counting on to know this stitch I need for my hoodie didn't know how to do it with wire. It's all good though, gotta keep the faith! I'm waiting until Sunday when I'll hit up this gift-making shindig and hopefully find someone who can hook it up with the right stitch (shoutout to adafruit for trying, but their instructions didn't quite cut it). Worst case scenario, I'll just have to improvise and use some pins or something to make it work. Anyways, enough about that, check out this sick bike I used to cruise around the biggest city in the US!
@Daniel0Winter Wonderland - Days 5 and 6/10! (#hardware-party)
I passed out before I could write an update yesterday, so this'll contain my progress for both today and yesterday 😅
Using bullet points because they seemed to work well for my last update:
• Printed motor slider block
• Proceeded to break motor slider block when I rode my bike without metal plates clamping the plastic :|
• Soldered banana plugs to ESC motor output
• Soldered hall effect sensor to long wire and crimped end to plug into ESC connector
• Added y-joint to power throttle and crimped throttle sense cable for ESC as well
• Assemble motor and speed controller to bike (use broken slider block because break is along layer lines and those will be clamped by aluminum plates)
• Cable management for wires on bike
• Hot glue hall effect brake setup to handles (only temporarily)
• Testing :)
CAD for reference
@Daniel0Winter Wonderland - Day 4/10! (#hardware-party)
I'm super tired today, so I'm going to keep this update short with bullet points:
• Got motor mounting plate made on router!
• Received last connector I needed to hookup battery to speed controller
• Soldered different connector types to wire
• Made first basic configuration for speed controller (completely untested)
• 3D print motor mount slider block
• 3D print pulley
• Assemble all major components to bike
• Wire everything (a lot of things!)
• Cable management
• Test the esc configuration
I thought of another addition to the project as well. It would be nice to have a small bike computer with gps and a high contrast e-ink style display. This is definitely not going to be possible in these 10 days, but it's another thing to do after the base bike is done!
As always, here's the CAD for reference, and I'm open to suggestions!
(The pictures will be better tomorrow I promise)
@Daniel0Winter Wonderland - Day 3/10! (#hardware-party)
I wasn't able to get my partial depth cut motor plate made today, so I put my attention towards some newly received hall effect sensors! Unlike the last pack I mistakenly ordered, these are ratiometric. This means that their output voltage is proportional to the strength of the magnetic field present (the ones I brought previously only functioned as magnetic switches).
This proportionality is important because these sensors will sense how much I pull the brake lever in order to vary the strength of regen braking. Having varying voltage also means that I'm going to have to tune the speed controller with minimum and maximum voltages output by the sensor.
Testing time! I only slightly burned myself by shorting the sensor, but the sensor was fine. After that slight mishap, I hooked it up to the oscilloscope and grabbed a neodymium magnet I plan to use on the bike. With that specific magnet, I tested the detection range of the sensor and from that determined where the magnet should be mounted for the greatest (while still detectable) range of brake handle motion.
I plan to use good old hot glue to mount the hall effect sensor and magnet to the bike, but if it ends up too janky, I'll design a 3D printed solution.
Aside from machining the motor mounting plate, I also need to 3D print my large pulley. Once that's done, I can get to assembling V1 onto the bike!

@Daniel0Winter Wonderland - Back Again for Day 2/10! (#hardware-party)
Today has been a pretty busy day for me, so I didn't get quite as much done as I wanted to. Nevertheless, progress has been made and you're here to see it.
First things first, I went through three different motor mount bracket revisions trying to get the angles just right (a tilted motor would lead to belt wear nightmares down the road).
After getting the motor mount sides printed, I decided to knock out a couple easy tasks, so I mounted the battery to the bike, which was easy to do with the water bottle holes already found standard on the bike frame. I also printed the mount for the speed controller (out of PETG for heat resistance) and gave it a test fit on the bike. While the part looks super pretty and clamped on to the frame well, it didn't have the friction to resist my pushing it down the tube. To solve this problem, I'm thinking of lining the inside of the clamp with electrical tape for its thin but rubbery surface.
One more super exciting thing - I got some of my aluminum plates machined at robotics! All I need now is the motor mount plate, which is a little bit more complex with its partial depth cut wings.
Just like the last post, feel free to message me with any questions or input!

@al0I went Fat Biking for the first time today it was a lot of fun
@reesericci0I worked on a spreadsheet to convince my parents that they should get me an ebike for my birthday:
@caleb0Today I went on a bike ride with the one and only @matt (the first official Hack Club New Hampshire Meetup!)
Saw a bunny (pictured) and a deer.
@m040First walk cycle :maya:@HenryBass-U02KEJ8T6D80What's the goal of life, if all of existence is an simply endless cycle of making something on firefox just for it to break on chrome?
Anyway remaking my portfolio, here's what I have so far. Tell me what you think, or if it even loads
(Also, I don't update my github as often anymore, so sadly my commits sorta hit a dead end, but I'm still working actively on a lot of projects)
@ella0Added a streaks page to the Scrapbook site. See the leaderboard at scrapbook.hackclub.com/streaks
I also rode a bike with clip-in pedals for the first time. I fell twice, but it was super fun. Also chased some geese.
@courtney0I went on a short bike ride yesterday around my neighborhood.
@matt0Rode 84 miles in Acadia this week! Tons of climbing and amazing weather. I’ve got some photos from my camera that I hauled the whole time that I’ll share here once edited! Coming home tmr :sad-yeehaw:
@Ishan0Oh no did I lose my streak.
Today I did a lot of things. We bought a bike from someone so I went to pick it up but it wouldn’t fit in the car so I rode it back home the whole way. Going up the hills was so painful. My parents and sister were in the car the whole time. I HAD SO MUCH FUN GOONG DOWNHILL AND INHALING THE SWEET FRESH MOUNTAIN AIR. Then we returned something at Kohl’s and then we went to Target where I bought two kinds of hot sauce, a really nice looking barbecue sauce, a slime thing for my sister, some chocolate cereal, almost a pair of walkie talkies. I can’t wait to try the sauces tomorrow. Then we went to mod pizza for the first time ever. What a concept: Subway but for pizza. Great brand image. Busy day so I didn’t get to see all the swap fun :smiling_face_with_tear::eggsdee:
Also here’s my teddy bear from since I was 2
@Odyssey3460Was around Mjøndalen with friends, I was supposed to also go to Drammen but unfortunately my friend had to go home so that's something we can do another day. Still pretty nice though! (13,37km, nice)
@Odyssey3460Biked to Drammen Sentum and back home with friends
@sampoder0my mum, brother and I went Palau Ubin today 🏝️ we cycled around it, had lunch, had an ice lolly, did more cycling, had another ice lolly and got on a boat.... ya and my mum made us take lots of selfies lol good time :)
@rishi0Went mountain biking with my friends again! My bike chain broke, but it I’m working on it :)
@rishi040km mountain bike trip done. Topics discussed with myself: the nature of learning, effective modelling, and why school isn’t worth it.
